Item Efeitos do armazenamento nos parâmetros físicoquímicos e resistência à Salmonella Enteritidis em ovos de ema (Rhea americana)(Universidade Federal de Goiás, 2014-02-12) Cervi, Renato Clini; Araújo, Luciana Batalha de Miranda; Rezende, Cíntia Silvia Minafra e; Café, Marcos Barcellos; http://lattes.cnpq.br/9860968235125158; Café, Marcos Barcellos; Bailão, Alexandre Mello; Andrade, Maria AuxiliadoraThe egg is an animal product with excellent nutritional value used in human food. The Ema (Rhea americana) is an animal of the Brazilian wildlife with potential to produce eggs that differ from other species in its microbiological resistance and percentages of nutrients. In order to obtain information about the chemical composition, resistance to Salmonella Enteritidis, and appropriate forms of storage for preservation of quality, were evaluated five lots of eggs from emus to assess quality in periods of seven , 14 , 21, 28 and 35 days of storage at refrigeration temperature , and three lots on 10 , 20 and 30 days to contamination of Salmonella Enteritidis. According to the results, it can be concluded that the internal quality changes with storage time, remaining viable up to 21 days of storage. The fractions of the egg change with protein degradation, and significant reduction in quality values, expressed in Haugh Unit. The eggs had high resistance to contamination by salmonella Enteritidis in all storage periods. Protein fractions of white and yolk and rheological parameters show differences from chicken egg, providing information to appropriate use of these products by the industry.Item Farinha de camarão em dietas para o tambaqui (Colossoma macropomum)(Universidade Federal de Goiás, 2015-03-03) Souto, Cristielle Nunes; Pádua, Delma M. Cantisani; Paula, Fernanda Gomes de; Guimarães, Igo Gomes; http://lattes.cnpq.br/1959358415883904; Guimarães , Igo Gomes; Miranda, Edma Carvalho; Oliveira, Denise Silva deThis study aimed to evaluate the feasibility of replacing soybean meal by shrimp meal in diets for tambaqui. In trial I, the coefficient of total tract apparent digestibility of the dry matter, protein, amino acids, fat, chitin, and organic matter was determined for shrimp meal, while in trial II, the growth performance of tambaqui fed diets containing graded levels of shrimp meal was evaluated. Triplicates groups of Tambaqui fingerlings with 2.7±0.72g mean initial weight were randomly assigned to 20 310L-aquaria and fed five diets that the soybean meal protein was replaced by shrimp meal protein at 0.0, 12.5, 25, 50 and 75%. The parameters evaluated were weight gain, feed intake, feed conversion ratio, specific growth rate, protein efficiency ratio, protein retention and diet with lower valuation was represented by higher replacement. Carcass chemical composition, haematology and serum biochemistry were analysed as well. Chitin seems not to be digested by tambaqui and tended to reduce the CTTAD of dry matter and organic matter. The CTTAD of amino acids were high and correlated to the CTTAD of protein. Fish fed diets containing the 48.6% shrimp showed the highest ash content (P<0.05). Haematology of tambaqui was not affected by shrimp meal inclusion. However, the number of thrombocytes and eosinophils increased in fish fed the diets with the highest shrimp meal level. The gain in weight was low with the highest level of shrimp meal inclusion, however, no effect of shrimp meal inclusion to the diets was observed in others growth parameters. Total serum protein and globulin levels increased according to the increase of shrimp meal levels (P<0,05). In sum, shrimp meal protein seems to be able to replace the soybean meal protein up to 75% in diets for tambaqui without reducing the growth performance or health status. A possible immune enhancer effect of natural chitin from shrimp meal may take place in tambaqui; however further studies are needed to confirm our hypothesis.Item Avaliação do efeito de variáveis produtivas na conversão alimentar de frangos de corte(Universidade Federal de Goiás, 2015-03-27) Lupatini, Flaviana; Stringhini, Jose Henrique; http://lattes.cnpq.br/8505634095383289; Café, Marcos Barcellos; http://lattes.cnpq.br/9860968235125158; Arnhold, Emmanuel; http://lattes.cnpq.br/7156945506134934; Café, Marcos Barcellos; França, José Maurício; Carvalho, Fabyola Barros deThe feed conversion is one of the more indexes monitored by poultry agroindustry, in order to keep their production costs within bounds economically viable. The present study was conducted in order to identify which variables productive have the greatest impact on feed conversion of broilers. Was used production data of poultry agroindustry in the central-west of Brazil. The field results were collected from January 2012 to September 2013, a total of 2,978 broilers flocks. The sample is composed of lots of commercial strains Cobb and Hubbard, not sexed. Was made analysis of variance with Tukey Test (P> 0.05), and analysis of variance in mixed model for the following qualitatives variables: year period, commercial strains, hatchery, incubator type, type of poultry house, homogeneity of flock weight at birth. The correlation and regression polynomial for the following quantitative variables: birth weight, weight to 7, 14, 21, 28, 35, 42 days, weight slaughter, slaughter age, mortality, average daily gain and time interval between flocks on the field. Statistical analysis was made through the statistical program R. The sum of squares in the mixed model, the variables that presented the greatest impact on feed conversion were: period of the year with 39.90%, type of poultry house with 35.70% and lineage with 17.80%. Between quantitative variables that had a greater correlation with the feed conversion ratio is the average daily gain,-0.57 (P < 0.01). Each gram in average daily gain results in nine grams in feed conversion. Flocks that showed lower mortality rate, showed greater correlation between average daily gain and feed conversion. Thus, in the present study, the variables that presented the greatest impact on feed conversion were: average daily gain and period of the year.Item Óleo-resina de copaíba e extrato de barbatimão na dieta de poedeiras comerciais infectadas por Escherichia coli(Universidade Federal de Goiás, 2015-04-17) Barbosa, Aleane Francisca Cordeiro; Café, Marcos Barcellos; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721288T1; Andradae, Maria Auxiliadora; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4780227J3; Leandro, Nadja Susana Mogyca; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4785461T6; Leandro, Nadja Susana Mogyca; Rodrigues, kênia Ferreira; Stringhini, José HenriqueThe present study was performed to evaluate the supplementation of copaiba oleo resin or barbatimão extract in the diet of laying hens challenged with Escherichia coli. A total of 200 Isa Brown laying hens (64-76 weeks old) were used, and all the birds were intravaginally inoculated with 0.5 mL of 0.85% sterile saline solution containing 8.8 x 109 CFU / mL of Escherichia coli. It was adopted the randomized complete block design (birds weight used as block criteria), with four treatments and five replicates of 10 birds. The treatments consisted of: basal diet without additives (control); basal diet + 30 mg / kg of antibiotic (halquinol); basal diet + 30 mg / kg of copaiba oleo resin and basal diet + 40 mg / kg barbatimão extract. The experiment lasted three periods of 28 days. At the end of each period, the performance and the external and internal egg quality were evaluated as the search for the presence of Escherichia coli in eggs; and at the end of the total period, the search for Escherichia coli in ovarian follicles and oviduct. Data were subjected to analysis of variance and means, when necessary, were compared by Tukey test (5%). For the Escherichia coli searching in eggs, follicles and oviduct, it was applied descriptive analysis (absolute and relative frequency). The inclusion of 40 mg / kg diet of barbatimão extract lead to worse feed conversion than the control treatment and decreased egg production compared to antibiotic treatment. The addition of 30 mg / kg diet of copaiba oleo resin did not influence the hens performance. The use of barbatimão extract lead to production of heavier eggs, and worse shell thickness and internal quality (UH) when compared to antibiotic treatment. Egg weight, the albumen percentage and the yolk index in the treatment with copaiba oleo resin were better than those of antibiotic treatment. However, the inclusion of copaiba oleo resin resulted in a lower yolk percentage when compared to antibiotic treatment. There was a lower frequency of isolation of Escherichia coli in intra-vaginal swabs samples from treatment with copaiba. The inclusion of barbatimão or copaiba provided lower frequency of isolation of E. coli in ovarian follicles in relation to antibiotic treatment. There was a lower frequency of isolation of E. coli in the oviduct with the addition of barbatimão extract when compared to antibiotic treatment. The treatment with copaiba oleo resin showed higher frequency of isolation of E. coli in the oviduct than the other treatments. The use of copaiba oleo resin or barbatimão extract resulted in lower frequency of isolation of Escherichia coli in the shell, albumen and yolk samples, in relation to antibiotic treatment. The inclusion of copaiba oleo resin may be an alternative to antibiotics in laying hens commercial diets.Item Relações de aminoácidos sulfurados: lisina digestíveis e diferentes fontes de betaína nas dietas pré-inicial e inicial de frangos(Universidade Federal de Goiás, 2015-05-07) Rezende, Pedro Moraes; Andrade, Maria Auxiliadora; http://lattes.cnpq.br/9441751521255467; Café, Marcos Barcellos; http://lattes.cnpq.br/9860968235125158; Stringhini, Jose Henrique; http://lattes.cnpq.br/8505634095383289; Stringhini, José Henrique; Laboissiere, Michele; Carvalho, Fabyola Barros deResearches with the use of betaine in broiler diets have shown its role inintestinal osmoregulator under stress, increasing cell water retention and its role as a methyl group donor in metabolic processes.The use of additives as betaine is a good economical alternative to feed chickens. The objective of this study was to evaluate growing relations of sulfur amino acids: lysine in combination with two sources of betaine in broiler diet in pre-starter and starter phases.The experiment was conducted at experimental poultry of School Veterinary and Animal Science of Federal University of Goiás in Goiânia, The experimental protocol was approved by the Ethics Committee on Animal Use / CEUA registered under protocol. 068/13. 504 chicks Cobb 500® males with a day old were housed, in galvanized steel batteries with five floors, troughs and linear feeders Division and incandescent lamps for heating.The experimental designused was randomized block in a 3x4 factorial design, corresponding to diets containing betaine (synthetic and natural) compared to the control with out use of the compound, and different relations of methionine+cystine: digestible lysine (57%, 65%, 73% and 81%), with 12 treatments, 6 replicates of 7 birds.The experimental diets of corn and soybean meal, free from growth promoters and anticoccidial, were formulated with the exception of methionine and cystine levels in the appropriate treatments, and the DLmethionine added to replace the starch. Performance was measured with the weighing of birds and diets on the accommodation and 7, 14 and 21 days of age, determining the average final weight, weight gain, feed intake and feed conversion, For the blood biochemical profile, blood was collected for determination of serum Na+, K+, Cl-, albumin, globulin, albumin:globulin, protein, cholesterol, triglycerides, HDL, VLDL, LDL and uric acid. Formetabolizability of nutrients was used the total excreta collection 4-7 days and 17-21 days of age, determining the coefficients of raw dry, nitrogen and nitrogen retained and nitrogen balance. Necropsies were done on chicks with 7 and 21 days of age, during which time samples were collected from the small intestine (duodenum, jejunum and ileum) for mounting histological slides and weighing the organs of the gastrointestinal tract (GIT). For histomorphometry, was checked villus height, crypt depth and villous:crypt duodenum, jejunum and ileum. Data were subjected to analysis of variance (P <0,10) and applied to polynomial regression analysis for methionine+ cystine: lysine. Al though there was no expressive difference in the use of betaine sources, you can check the sparing effect of methionine, as the birds fed the lower methionine+ cystine: lysine showed higher weights when supplemented with betaine, in particular the source of natural betaine. There was a positive interaction of betaine on the Met+Cys relations: Lys digestible for blood biochemistry profile, villus height and metabolization of nutrients.Item Degradabilidade in situ de silagem de cultivares de milheto com inclusão de casca de soja(Universidade Federal de Goiás, 2015-07-01) Lima, Mayra Lôbo de Vellasco; Eichler, Verner; http://lattes.cnpq.br/8631385299972581; França, Aldi Fernandes de Souza; http://lattes.cnpq.br/0724478254270327; França, Aldi Fernandes de Souza; Magalhães, Roberto Toledo de; Basto, Débora CarvalhoAvaliou-se a degradabilidade in situ da silagem de milheto (Penisetun glaucum (L.) R. Br.) cultivares ADR500, BRS1501 e ADR8010 com a inclusão de diferentes níveis de casca de soja (0%, 3%,6% e 10%). Foram utilizadas três vacas mestiças Holandês x Zebu, fistuladas no rúmen, com peso corporal aproximado de 450kg. O delineamento experimental adotado foi o de parcelas subdivididas em arranjo fatorial 3 x 4, com três repetições, totalizando 36unidades experimentais. Os tempos de incubação foram em ordem decrescente de 144, 72, 48, 24, 12, 0h. O tempo zero foi utilizado para o cálculo da solubilidade das forrageiras. Os resultados obtidos foram submetidos a análise de variância e a comparação de médias realizada pelo teste de Tukey à 5% de probabilidade e à regressão polinomial para avaliação dos efeitos dos níveis de casca de soja. Por meio da técnica in situ, é possível estimar parâmetros relacionados à cinética da degradação de um alimento e de suas frações, em função de períodos de incubação no rúmen. Para efeito isolado de cultivar, não foi observado (P>0,05) para os parâmetros de degrabilidade ruminal da (MS). Não foi observado efeito de interação (P>0,05) para entre as cultivares e os níveis de inclusão de casca de soja para a matéria seca (MS) nas frações “a” e “b”, taxa de degradação (TD), degradabilidade efetiva (DE) nas taxas de passagens 2, 5 e 8%, fração indegradável (FI) e degradabilidade potencial (DP). Houve efeito significativo (P<0,05) entre os níveis de inclusão de casca de soja para a fração “b” (fração potencialmente degradável), TD, DE nas taxas de passagens 2 e 5%, FI e DP (%), foram realizadas equações de regressão, para análise dos efeitos isolados de níveis. Para a matéria orgânica (MO), não foram observadas nenhuma interação (P<0,05) para os parâmetros de degradabilidade in situ analisados. Entre as cultivares, foram observadas diferenças significativas (P<0,05) para a fração “b”, onde a cultivar BRS1501 apresentou maior valor quando comparada as demais cultivares. Para efeito de níveis, foram observadas diferenças significativas (P<0,05) para a fração “b”, TD, DE na taxa de passagem a 8%, FI e DP(%). Para a análise da degradabilidade in situ da proteína bruta (PB), foram observadas interações entre as cultivares e os níveis de inclusão de casca de soja para a fração “b”, onde a 3, 6 e 10% de inclusão de casca de soja a cultivar ADR500 apresentou menor degradabilidade para a degradabilidade efetiva a 2%. Diferenças significativas (P<0,05) foram observadas nos quatro níveis de inclusão de casca de soja para a DE onde a cultivar ADR500 apresentou menores valores enquanto a ADR8010, apresentou valores de degradabilidade efetiva a 5%; as três cultivares de milheto apresentaram maior degradabilidade no nível de inclusão a 6% de casca de soja. Para a degradabilidade potencial (DP), a cultivar ADR8010 apresentou maior no nível de inclusão a 6%, observa-se também que quando a inclusão de casca de soja é aumentada para o nível de inclusão a 10%, a DP é reduzida nas três cultivares.Item Efeito antioxidante do subproduto da goiaba na dieta de frangos sobre o desempenho e a qualidade de carne(Universidade Federal de Goiás, 2015-07-09) Oliveira, Maryelle Durães de; Mascarenhas, Alessandra Gimenez; http://lattes.cnpq.br/9082632592936909; Mello, Heloisa Helena de Carvalho; http://lattes.cnpq.br/5510965166352073; Mello , Heloisa Helena de Carvalho; Rocha, Fernanda Rodrigues Taveira; Leandro , Nadja Susana MogycaAn experiment was conducted with the objective of evaluating the antioxidant potential by product Guava as nutritional additive in broiler rations aimed at improving intestinal integrity, metabolism of nutrients, the growth performance of animals and the meat quality . 288 female chicks were housed, Cobb500 lineage, with one day old galvanized wire batteries. The experimental design was completely randomized, consisting of four treatments (0%, 0.5%, 1.0% and 1.5% of guava byproduct.) And six replicates of 12 birds / cage each. The diets were isonutritives. The feeding program comprised two phases: pre-starter feed (1 to 7 days old), starter (8 to 21 days of age). The byproduct of guava was added to the basal diet replacing starches. The final weight was measured, the weight gain, feed intake and feed conversion at 21 days of age. The metabolizability of the dry matter and nitrogen was assessed in metabolic assays conducted from 17 to 21 days of age. At 21 days of age were sacrificed for the collection chest, thigh and drumstick to the analysis of colorimetry, pH and reactive substance to thiobarbituric acid (TBARS) and fragments duodenum, jejunum and ileum were collected for preparation of histological slides, and later , measurements of villus height and crypt depth of the intestinal mucosa. The data were submitted to ANOVA and mean test, was adopted α = 0.05%. Guava byproduct did not improve the performance of the birds, and did not harm any of the variables studied. The pH of the colorimetrically and breast and thigh were not influenced by the use of guava byproduct. There was less TBARS value, indicating lipid oxidation of lower thigh meat, the inclusion of 1.5% of byproduct of Guava that was statistically similar to include 0.5 to 1.0%, which shows the characteristic antioxidant guava. There was no influence of guava byproduct levels used to average values of TBARS in the breast meat samples. There was no significant difference (p> 0.05) between treatments for the villi height variables, crypt depth and villus / crypt of the duodenum and jejunum. It is observed significant result for depth variables crypt and villus: crypt. For metabolizing analysis of nutrients in all studied variables obtained significant differences (p> 0.05).Item Efeito do resveratrol na qualidade e desenvolvimento de embriões bovinos criopreservados ou conservados em meio holding(Universidade Federal de Goiás, 2015-08-04) Silva, Ariany Rafaella Neto; Santos, Klayto José Gonçalves dos; http://lattes.cnpq.br/3121469559821246; Viu, Marco Antonio de oliveira; http://lattes.cnpq.br/7829414158162743; Viu, Marco Antônio de Oliveira; Meirinhos, Maria Lúcia Gambarini; Lopes, Dyomar ToledoThis study was developed with the objective of evaluating the response of bovine embryos produced in vitro (PIV) the addition of resveratrol (Resv) to recultivo to embryos vitrified (Experiment 1-E1) and medium Holding for fresh embryos (Experiment 2-E2) to check the maintenance or improvement in the quality of these embryos. In E1 PIV vitrified bovine embryos were heated and recultivados in the medium containing 0.5 μM of resveratrol, evaluating the re-expansion rates, hatching and cell quality by analysis of TUNEL. In E1, the hatching rate of recultivo more than 24 hours after (P < 0.05) in the Resv Group (37,7 vs. 19,1%). The rate of embryos according to the stage of development did not show difference between treatments. Even in E1, for fresh embryos PIV the total number of cells (NTC) was superior to that found in the vitrified embryos (131,6 vs 88,8 and 82,7%) , as well as the NCA (number of apoptotic cells) was lower (6,3 ± 0,8) compared with control groups and resveratrol (15,8 ± 1.2 and 13,5 ± 1,0), which did not differ among themselves in these variables. No difference was observed in embryos degenerates and reactive oxygen species (ROS) and Glutathione (GSH). In E2 bovine embryos were fresh bottled PIV in 0,25 ml straws with a holding in the presence (TR6 and TR10) or absence (TH6 and TH10) of resveratrol and kept on warming plate to 36° C in different times, six and 10 hours, followed by the unloading spouts and recultivo until 24 hours. Hatching rates at 24 hours of embryos treated with antioxidant tended to be greater than in the control. Bx TR10 rates was higher (51,2%) the TR6 (30,8%) (P < 0.05), the other stages of development were similar, the NTC was lower in TH10. The index of EROS was superior in TH10 (23,4126 ± 1,5661). The values of the GSH TR6 (95,2208) were larger than TH6 (30,7594) (P < 0.05), the TR10 issuing GSH (49,5330 ± 6,5332) did not differ from TH10 group (47,2044) (P > 0,05).Item Uso do extrato seco de barbatimão (Stryphnodendron adstringens) e óleo bruto de sucupira (Pterodon emarginatus) e monensina na dieta de vacas leiteiras(Universidade Federal de Goiás, 2015-10-08) Jesus, Flávia Duarte de; Ferreira, Reginaldo Nassar; http://lattes.cnpq.br/2555785079833283; Arnhold, Emmanuel; http://lattes.cnpq.br/7156945506134934; Arnhold, Emmanuel; Malaquias Júnior, João Darós; Zacaroni, Ozana de FátimaVarious synthetic additives are used in feed for ruminants with a view to improving production efficiency. However, the consumer society is increasingly criticizing the use of these products. The ever-increasing demand for healthy and safe food is causing great pressure in various sectors of agriculture. Thus, in order to develop sustainable technologies, have been used two plants of the Cerrado, the Barbatimão and Sucupira, that have proven antimicrobial activity. The objective was to evaluate the effects of natural additives Barbatimão and Sucupira on consumption and total apparent digestibility of dry matter and nutrients, ruminal fermentation, milk yield and composition and productive efficiency. The used treatments were: Control (M): Inclusion of 22,5mg / kg DM of Monensin Sodium; Barbatimão (B1000): inclusion of 1000mg / kg MS of active Ingredient of dry extract of barbatimão ; Barbatimão (B500): inclusion of 500mg / kg MS of active Ingredient of dry extract of barbatimão; Sucupira (S250): inclusion of 250 mg / kg DM of crude oil of Sucupira; Sucupira (S500): inclusion of 500mg / kg DM of crude oil of Sucupira. Where utilized five crossbred lactating cows. The design utilized was a 5x5 Latin square design with periods of 21 days, 14 for adaptation of animals and seven for data collection. For the variables consumption of crude protein (CP), ether extract (EE), non-fibrous carbohydrates (NFC), and total carbohydrate (TC), there was no statistically significant difference (p> 0.05) between neither treatment. The averages of dry matter intake for the B1000, S500 and S250 treatments did not differ (p <0.05) to the treatment M. For the variable percentage of dry matter intake relative to body weight all natural additives statistically similar means (p <0.05) M, except B500 treatment, which averaged more than M (p <0.05). The results of the fiber intake of neutral detergent fiber (NDF) and percentage of NDF intake in relation to body weight showed that only treatment S500 was able to affect these variables similarly to monensin (p <0.05). There was no statistically significant difference (p> 0.05) between treatments evaluated for the average pH and ammonia nitrogen concentration of rumen fluid. No statistically significant difference (p> 0.05) between the averages of DM, OM, CP, EE, TC and NDF in neither of the treatments. The digestibility of NFC was no statistical difference (p <005) only between treatment M and B500, in which the digestibility for B500 was smaller than M (78.62 vs 71.16). For the averages of milk production, corrected milk production and milk composition were no statistically significant differences (p> 0.05). There was also no statistically significant difference (P> 0.05) between the averages of treatments when evaluating production efficiency.Item Características bromatológicas e perfil fermentativo da silagem de milheto forrageiro (pennisetun glaucum) aditivado com casca de soja(Universidade Federal de Goiás, 2015-10-13) Silva, Renan Sousa da; Rosa, Beneval; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783900J0; Miyagi, Eliane Sayuri; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4761394J4; Miyagi, Eliane Sayuri; Eichler, Verner; França, Aldi Fernandes de SouzaThe ensiling process is a much used alternative in animal husbandry systems, consisting in the preservation of moist forage, fresh-cut or pre-dried, with high nutritional value, to be administered in times of food shortages. Brazil is characterized by a strong seasonality and basically has two distinct seasons in some regions of the country, one high and one low rainfall. The tropical grasses used in Brazilian pastures lose their quality and produce less in times of drought and low temperatures. All these factors justify the use of silage technique. The objective of this study is to evaluate four different levels of inclusion of soybean hulls in millet forage silage in order to determine the nutritional increments that it provided, in addition to analyzing the fermentation process associated losses of the silage process. The bromotalógica composition was positively affected by the inclusion of soybean hulls, with .lineares increases in DM and CP levels. The NDF also an increase in the levels. The inclusion of soybean hulls in silage millet reduced losses by gases and effluents, keeping stable the recovery of dry matter. The ammonia levels were reduced with the addition of the additive. Soy hulls did not affect the lactic acid content, acetic and butyric within acceptable Nives no statistical difference. The work also revealed a slight decrease in propionic acid. The titratable acidity and pH levels of silage did not differ. Palavras Chaves:Item Valor nutricional e características fermentativas da silagem de capim-mombaça com adição de farelo de girassol(Universidade Federal de Goiás, 2015-10-15) Costa, Eduardo Rodolfo da; Costa, Adriana Rodolfo da; http://lattes.cnpq.br/8142254771826531; França, Aldi Fernandes de Souza; http://lattes.cnpq.br/0724478254270327; França, Aldi Fernandes de Souza; Souza, Flávio Faria de; Bastos , Débora de CarvalhoThe nutritional value and fermentative characteristics of the silage grass mombaça with sunflower meal inclusion were evaluated. The treatments consisted of four levels of inclusion: 0%, 10%, 15% and 20%. The levels of dry matter determined in silage grass mombaça, differed depending on the sunflower meal inclusion levels, ranging from 24.69 % to 28.50%. The CP content ranged from 11.63 % to 21.651 % and significant differences were observed between the inclusion levels (P<0.05). The highest level of sunflower meal inclusion - 20% - resulted in smaller losses by effluent. The pH values found varied between 4.89 and 5.57. The average levels of ammonia nitrogen (NH3-N) remained between 1.33 and 6.42. The average levels of residual soluble carbohydrates ranged between 4.63 and 8.38, with significant similarity only between the levels of 15% and 20 % of sunflower meal (P> 0.05). The contents of lactic acid, acetic, propionic and butyric ranged from the 1,245 to 3,898; the 2.428 to 8.670; the 0.248 to 0.135 and the 0.016 to 0.027 respectively, and differed significantly (P<0.05) between the sunflower meal levels. The degradability of the dry matter of silage varied as a function of sunflower meal inclusion levels , having the potential degradability (PD) between 71.46 % and 81.96 %, being to 27.86 % to 32.83 % variation to the fraction "a" and between 39.01 % and 52.07 % for the "b" fraction . Regarding the CP, PD ranged from 83.09 % to 92.57 %, and the contents of the fraction "a", fractions "b" and part "c", were significantly influenced by the addition levels sunflower meal (P < 0.05) showing variation of 24.79 % to 61.50 %, 28.68 % to 59.73 %, and 0.0194 % to 0.0411 %, respectively.Item Taxa de alimentação para juvenis de pirapitinga criados em hapas(Universidade Federal de Goiás, 2015-10-19) Zarpellon, Idayana; Paula, Fernanda Gomes de; http://lattes.cnpq.br/9353071033895125; Arnhold , Emmanuel; http://lattes.cnpq.br/7156945506134934; Paula, Fernanda Gomes de; Oliveira, Raquel Priscila de Castro; Santin, Ana Paula IglésiasThis study was conducted in order to evaluate the effect of different feeding rates on growth performance, economic evaluation, morphometric characteristics and blood biochemistry of pirapitinga (Piaractusbrachypomus) in ponds during rearing.

The experimental design was completely randomized with 4 treatments and 4 replications, totaling 16 experimental units. Data were submitted to analysis of variance, means were compared by 5% Tukey test and regression analysis for the inclusion levels. dry matter content (DM) determined in silage differ (P <0.05) as a function of the MDPS inclusion levels, ranging from 26.53% to 38.69% control treatment and for treatment with higher level inclusion. For values of organic matter found a significant difference only from the IV treatment with 15% inclusion of CEC (P <0.05) compared to other treatments. Regarding crude protein (CP) observed a linear increase (P <0.05) due to the increase of CEC levels, ranging between 9.46% and 14.92%. NDF and the FDA determined in silages ranged from 58.50% to 66.25% and 31.25% for FDA to 38.50 for the FDA so there significant differences between treatments. For certain ether extract in silages millet forage with inclusion of MDPS ranged from 3.13 to 3.95%. The content of mineral matter (MM) showed a significant difference (P <0.05) according to the MDPS inclusion levels, ranging from 5.26 to 7.55%. The inclusion of MDPS reduced (P <0.05) losses gases and effluents in all the treatments, ranging from 6.10 to 3.48 for gas losses and 9.05 to 17.28 for losses effluent and contributed significantly in the dry matter recovery process (MS). The buffer power values (PT), pH and ammonia-N were influenced (P <0.05) by the inclusion of different levels of ground ear corn silage. The levels of acetic, propionic, butyric and lactic, so influenced by the addition of ground ear corn silage. The soluble carbohydrate values have an increasing depending on the MDPS inclusion levels, proving to be efficient in their use to improve the fermentation profile of silages.Item Parâmetros fisiológicos e tricológicos na avaliação do conforto térmico em bovinos de corte(Universidade Federal de Goiás, 2016-02-29) Mastelaro, Ariadne Pegoraro; Alves, Fabiana Villa; http://lattes.cnpq.br/1153061642306224; Hellmeister Filho, Paulo; http://lattes.cnpq.br/4391389845941028; Miyagi, Eliane Sayuri; http://lattes.cnpq.br/5838290185532582; Miyagi, Eliane Sayuri; Menezes, Gilberto Romeiro de Oliveira; Bocchi, Adriana LuizeThis study aimed to evaluate the physiological responses and morphological characteristics of cattle belonging to four different genetic groups with different degrees of heat adaptability, raised in pastures in the Center - West of Brazil. The experiment was conducted in two experimental periods (March and August 2015), at São Carlos Farm, Três Lagoas (MS). 54 calves recently weaned from four genetic groups were used, 14 Nellore, 14 Senepol, 12 ½ Angus x ½ Nelore and 14 ¼ Brahman ¼Nelore x 2/4 Senepol, with age, in the beginning of the experiment, five seven months. The average weight of the animals was 197.0 kg (Nelore), 169 kg (Senepol), 235 kg (½ Angus x ½ Nellore) and 233 kg (¼ Brahman x ¼ Nellore x 2/4 Senepol). The experimental design was completely randomized, with four treatments (breeds), where repetitions are the animals within each genetic group. They measured the temperature (rectal, superficial skin and superficial hair coat), heart rate, respiratory rate and surface skin temperature, surface temperature of fur and sweat rate. Moreover, it was determined some morphologic characteristics of the dorsal region. To characterize the environment, there were collected dry bulb temperature, black globe temperature, dew point temperature, wind speed and relative humidity, the sun and the shade, to determine the following thermal comfort indexes: index temperature and humidity, globe temperature and humidity index, and radiation heat load. Among the adaptive features, only those relating to the present differences between the experimental groups (p <0.05), and the genetic group ½ Angus x ½ Nellore showed the highest values of length, diameter, number of hair, density medium and thickness of the hair coat cover in both evaluation periods (March and August). For physiological variables, there was no statistical difference between the experimental groups (p> 0.05), a fact that was also found in the evaluated periods (p <0.05). It follows, therefore, that the choice of breeds with characteristics consistent with the breeding environment is an important factor in the production system efficiencyItem Aditivos fitogênicos e ionóforos na degradabilidade da fibra e parâmetro metabólicos em bovinos(Universidade Federal de Goiás, 2016-03-01) Almeida, Jean Sardinha de; Ferreira, Reginaldo Nassar; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4787019Y5; Padua, João Teodoro; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721189P8; Pádua, João Teodoro; Taveira, Rodrigo Zaiden; Miyagi, Eliane SayuriThe objective this paper was evaluate the inlcusion of crude extract of Croton urucurana Baillon or composed of essential oil of cashew and castorbean oil or monensin on the degradability of dry matter and fiber in vitro and dry matter in situ and fermentation ruminal metabolic parameters in beef cattle. The experiment was conducted in the Institute of Biological Sciences (ICB) and the School of Veterinary and Animal Science of the Federal University of Goiás – GO, from August 2015 until January 2016. There were four treatments through in vitro technique: control, monensin, Croton urucurana Baillon, biophytus (functional oil composed of cashew and castorbean), with five repetitions. Were evaluated the parameters of degradability of dry matter. Metabolic analysis and in situ was through four animals distributed in a Latin square, were measured glucose, urea, urea nitrogen in the blood, aspartate aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase, albumin, total bilirubin and factions, creatinine, Total cholesterol, HDL, LDL, VLDL, triglyceride and lactate dehydrogenase. Ruminal parameters were determined by protozoa count, ammonia nitrogen, pH, short chain fatty acids, bacterial reductive activity. The experimental design was completely at random. The data were submitted to analysis of variance and compared by Tukey test at 5% probability. The treatments did not increase the IVDMD (P> 0.05). There was no significant effect (P> 0.05) of the treatments on in vitro degradation parameters of DM and NDF in all evaluated times. For MS degradability in situ parameters, there was a significant effect (P <0.05) between treatments for soluble and effective degradation fraction with 2% by pass rate. The DM intake, had significant difference (P <0.05) between treatments, with lower consumption for monensin with admission was independent of diet type, either directly via the rumen cannula, it can be show that the lower consumption of diet with monensin supplementation is not by means of sensory but physiological and metabolic mechanisms. There was no significant effect (P> 0.05) for pH between treatments, but the collections after feeding was significant (P <0.05) monensin treatment, occurring up before feeding up two hours. Acetic acid levels were significant (P <0.05) for the hours of collection. The levels of butyric acid was affected by treatments (P <0.05) and not the hours of collection (P> 0.05). The concentrations of AST, GGT, LDH FA and was not affected by treatments (P> 0.05). The inclusion of essential oils, Croton urucurana Baillon and monensin in beef cattle diets hay base has not improved the evaluated parameters. The effective degradability of dry matter had better results with the inclusion of functional oils composed cashews and castorbeans. The intake was influenced by monensin and functional oil in addition the fuction of the two are similar, can be used one over the other.Item Utilização de misturas de coprodutos em rações de vacas leiteiras(Universidade Federal de Goiás, 2016-03-04) Ferreira, Lorrany Bento; Lima, Milton Luiz Moreira; http://lattes.cnpq.br/7562710128026687; Fernandes, Juliano José de Resende; http://lattes.cnpq.br/7949776443064259; Zacaroni, Ozana de Fátima; http://lattes.cnpq.br/4582215859105753; Zacaroni, Ozana de Fátima; Amaral, Alliny das Graças; Ribeiro, Marinaldo DivinoThe objective of this study was to evaluate the partial replacement of corn silage and concentrate mixtures of by-products on the dry matter intake, milk yield and composition, conditioned meal, apparent digestibility in the digestive tract and feeding behavior of dairy cows. Nine multiparous lactating cows, coming from Holstein x Jersey cross, were confined in tie stall stalls and used Latin square 3x3 replicated, with periods of 18 days. The treatments were (% DM): Control - 53.5% corn silage and 46.5% concentrate; Mixture 1-43% corn silage, 30% concentrate and 27% of by-products of mixture 1 and Mixture 2-18% corn silage, 31% concentrate and 51% of by-products mixture 2. The feed was provided individually twice a day in complete diet. In each period, the offered food, leftovers and feces were collected, quantified and analyzed for dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber ( NDF) and mineral matter (MM) to determine the intake and digestibility. The production of milk was recorded at the end of each experimental period, wherein the milk samples were collected and composed of two daily milkings and analyzed for fat, protein and lactose. The conditioned meal was assessed on days one, seven, and 14 of the experimental period, in which the feed was weighed two hours after its supply in the morning. The masticatory activity was visually assessed every 5 minutes for 24 hours. Statistical analysis was performed with PROC MIXED SAS and the means compared by Tukey test at 5% significance level. The dry matter intake, production and composition of milk did not differ (P>0.05) between treatments Control and Mixture 1. Mixture 2 treatment decreased (P<0.05) dry matter intake (13.2 vs. 15.9 kg /d) producing corrected milk fat (22.7 vs. 25.3 kg / d), fat content (3.63 vs. 4.06%), protein (2.87 vs. 3.07 %) and lactose milk yield (1.11 vs. 1.17 kg / day) compared to the Control treatment. There was no effect (P>0.05) on the digestibility of DM, OM and NDF between Control and Mixture 1 treatments, however the Mixture 2 treatment DM digestibility (65.8 vs. 58.4%) and MO (68.6 vs. 60.6%) were higher (P<0.05) compared to Control. MS consumption in the conditioned meal was lower (P<0.05) on day seven and 14 for Mixture the 2 treatment compared to the Control. The intake variables, rumination and chewing did not differ (P> 0.05) between the Control and Mixture 1. Mixture 2 and the treatment rumination times (425 min/d) and chewing (640 min/d) were lower (P<0.05) compared to Control. The Mixture 1 treatment can be used without loss in animal productivity, however treatment Mixture 2 depressed the dry matter intake, milk production and solid content.Item Influência do enriquecimento ambiental no comportamento e desempenho de leitões na fase de creche(Universidade Federal de Goiás, 2016-03-08) Oliveira, Marcus Vinicius Garcia de; Di Campos, Melissa Selaysim; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4717226U7; Mascarenhas, Alessandra Gimenes; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4795211T6; Nunes, Romão da Cunha; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4796163U1; Di Campos, Melissa Selaysim; Silva, Ana Carolina de Sousa; Hellmeister Filho, PauloThe animal welfare assessment techniques are used to check the stress level of the animals. Swine production has been reported as one of the most stressful livestock. The nursery phase is heavily critical, whereas the piglets are liable to several agent stressors leading them to welfare state decrease and causing stereotyped behaviors. One way to reduce the issues stress in the nursery phase is environmental enrichment technique. This technique consists in providing enriching objects that stimulate the exploratory behavior pigs, increasing the well-being and animal cognition improvement. However, the enriching object pigs adaptation with permanent presence in pen leads to decreased of interaction frequency with the enriching object. Environmental enrichment in time intermittently may increase the piglets interaction frequency with enriching object, promoting the novelty aspect and increasing well-being. Therefore, the aim of the study was to evaluate the effect of time intermittently of environmental enrichment on the novelty effect and interaction frequency of piglets with enriching object (wheelbarrow tire) and its influence on the nursery piglets behavior and performance. Were used 720 piglets in nursery phase of both sexes. The piglets were assigned into four treatments: WEO - without enriching object; PEO - permanently enriching object; WEO24 - No enriching object with 24h intermittent; WEO48 - No enriching object with 48h intermittency. Were evaluated the piglets behavior whereof ethogram, the Black Globe and Humidity Index(BGHI) effect in the behavior, injury score, diarrhea score and performance. There was recorded a significant effect (p <0.05) in the piglets interaction with enriching object for treatments with intermittent time and A significant effect (p <0.05) of environmental enrichment treatments in reduce stereotypes behavior (WEO: 7.62%; PEO%: 6:21%; WEO24: 6,31%e WEO48: 6.59%). The BGHI variation changed the piglets behavior. Significant effects were observed (p <0.05) for lesion score values, diarrhea and performance among the treatments. The higher interaction frequency with the enriching object was observed in piglets submitted to, whereas was observed that the intermittency time promoted the novelty aspect when was reintroduced into the environment. The decreased stereotyped behavior increasing the piglets welfare. However, the intermittency time did not influence the piglets performance.Item Sistemas de terminação de cordeiros do grupo genético pantaneiro(Universidade Federal de Goiás, 2016-03-08) Villafuerte, Sergio Giovanni Espinosa; Franca, Aldi Fernandes de Souza; Costa, José Alexandre Agiova da; Restle, João; http://lattes.cnpq.br/7559938697233077; Restle, João; Zimmer, Ademir Hugo; Batos, Débora de CarvalhoPantaneiro genetic sheep group are native to the Pantanal Biome, in the Midwest region of Brazil, which is characterized by the production of meat. They are usually created under pasture, and the lambs usually finished in confinement. But should be considered sustainable and intensive finishing systems, adapted to the region. The aim of this study was to evaluate four finishing systems, including the productive performance and economic results as profitability indicators. Were used 54 lambs, 24 males and 30 females, wormed at weaning, with initial weight of 16.70 kg, with a mean age of 74 ± 9 days. Finishing systems were; Feedlot with corn silage (Zea mays) (CS) as roughage; Feedlot with mix corn silage and Pigeon pea (Cajanus cajan cv Mandarin) as roughage (CPS); Integration Crop-Livestock (ICL) grazing Brachiaria brizantha cv. BRS Piatã grass with Pigeon pea (Cajanus cajan cv Mandarin) in succession to mixed cultivation; stockpiled pasture (SP) with Brachiaria brizantha cv. BRS Piatã grass. All treatments the animals received energy-protein concentrate supplementation (16% CP and 82% TDN) equivalent to 2% of body weight. The experimental design was completely randomized in a factorial design, with four finishing systems and two sexes. The variables were final weight (FW) and average daily gain (ADG), and economic evaluation. Finishing systems under CS and ICL, obtained better productive performance not differing significantly from the CPS, which in turn did not differ statistically from SP. However, the economic evaluation demonstrated that the ICL and CPS systems were more profitable in finishing lambs. The pasture system formed in Integration Crop-Livestock with supplement of 2% of body weight, proved to be the most appropriate for the Midwest region in the finishing of Pantaneiro lambs in the dry season.Item Comportamento preferencial de leitões na fase de creche em ambiente enriquecido(Universidade Federal de Goiás, 2016-03-09) Leal, Guilherme Brunno de Medeiros; Di Campos, Melissa Selaysim; http://lattes.cnpq.br/1636247556914689; Nunes, Romão da Cunha; http://lattes.cnpq.br/4335133347523404; Di Campos, Melissa Selaysim; Silva, Ana Carolina de Sousa; Taveira, Rodrigo ZaidenThe welfare's absence in animal breeding has a direct impact on food production, affecting internal trade and especially exports. Environmental enrichment is the improvement of facilities in order to make the environment more appropriate to behavioral needs. Inserting objects in the environment such as, tires, chains, ropes, plastic bottles, wood or plastic bars are the most common types of environmental enrichment. However, only few tests have been made on swine's preference by the types of objects available to enrich its environment. It was aimed to evaluate the preferred behavior, as well as, animal performance (daily feed intake, daily weight gain, feed conversion) and lesion rates in pigs in the nursery stage using different types of objects (tire and metal chain), and scenarios (suspended, embedded in the wall, fixed on the floor). The experiment was performed in a commercial farm from July 30 to September 21, 2015. The animals were housed in collective cages, partially slatted floor, equipped with semi-automatic feeders and nipple drinkers. Every room with eight cages 113,02 ft² each, which makes a 2712,51 ft² experimental area. 696 pigs were used in Choice Genetics® breed, with an average age of 21 days, average weight of 12,34 pounds, divided between males and females. The pigs were divided into the treatment groups of 29 animals. The experimental design was a randomized block, with four different presentation scenarios of objects (control = without enriching object; T + C suspended = tire + suspended metal chain; T + C wall = tire and embedded metal chain on the wall; T + C floor = tire and fixed metal chain on the floor), repeated six times in a row. Camcorders were used for filming and subsequent evaluation of the behavior recorded every 10 minutes during 11 hours per day (7 a.m. to 6 p.m.), once in a week, 41 days. In the treatments with environmental enrichment, there were differences in the interaction with enriching objects (P <0.05). Regarding the presentation and the type of object, the animals preferred the suspended position and metal chain, respectively. The animal performance factors (daily feed intake, daily weight gain, feed conversion), and lesion rates, were not influenced by environmental enrichment.
