Item Biometria dos dígitos de bovinos e bubalinos e possivel relação com enfermidades podais(Universidade Federal de Goiás, 2012-12-21) Campos, Suyan Brethel dos Santos; Menezes , Liliana Borges de; http://lattes.cnpq.br/2012543423092393; Beletti , Marcelo Emílio; http://lattes.cnpq.br/1895300906751714; Silva, Luiz Antônio Franco da; http://lattes.cnpq.br/0446055905975647The morphometric study of the digits of cattle and buffaloes can contribute to understanding the pathogenesis of foot diseases and may serve as a valuable tool in the selection of animals with the intention of reducing the harm caused by these bulky disease in cattle. Several breeds of cattle and buffaloes still need further studies to determine such measures. The aim of this study was to describe and compare the measurements of the digits of cattle in CurraleiroPantaneira and Nellore and Murrah buffaloes. After submission and approval by the Ethics Committee of the Universidade Federal de Goiás, Protocol No 189/11, were used 80 ends distal limb locomotion of healthy cattle and buffaloes. Members were obtained in Refrigerator under Federal Inspection, disjointed carpal-metacarpal joints and tarsal-metatarsal being used only the fore and hindlimbs rights. The morphometric measurements were obtained with the aid of a mechanical caliper graduated and angles of tweezers conferred through metal protractor. The main parameters evaluated in digital chest and pelvic limb of each animal was measured both using the digit digit as medial side were dorsal hoof angle (A), dorsal wall length (B), the bead height (H), clip height (D), the hull length (L), diagonal length of the hull (F), the digit lateral width (G), the digit width medial (M), length of the digit side (I) and medial digit length (J). For comparison of average results between races we used the Tukey test (p <0.05). Multivariate analysis for the graphical representations of canonical variables was used to express the similarity of the variables between the groups in which they used the software R. The average weight obtained at the end of the experiment each group of cattle and buffaloes was analyzed to establish a possible correlation between the measures of the digits and the size of the animals used in the experiment. The results revealed that the major buffaloes present morphometric measurements for the variables B, C, D, E, F, G, H, I and J, only the variable A (dorsal hoof angle) that have lower angles to different breeds cattle studied. We conclude that there is evidence that morphometrics influence the occurrence of illnesses digital, but does not act as an isolated factor, requiring interaction with other structural factors, and environmental management for the manifestation of these diseases.Item Avaliação da toxicidade aguda e subcrônica do aspidosperma subincanum (apocynaceae) em camundongos(Universidade Federal de Goiás, 2013-09-03) Costa, Thays Nascimento; Moura , Veridiana Maria Brianezi Dignani de; http://lattes.cnpq.br/8773201078957745; Sant’Ana , Fabiano José Ferreira de; http://lattes.cnpq.br/5101695721028346; Damasceno, Adilson Donizeti; http://lattes.cnpq.br/3900110295277130In order to define the safety of phytotherapeutic use of plants is important an evaluation of the toxic potential by clinical, laboratory and histopathological studies in animals after exposure to extract of parts of the plant in different intervals of time. Due to bark infusion from species of Aspidosperma is employed without proof of its toxic potential in treatment of the diabetes mellitus, hypercholesterolemia and gastric disorders, this study proposes an experimental test with ethanolic extract of Aspidosperma subincanum to verify if induces acute and subchronic toxicity in heart, liver and kidneys of mices (Mus musculus). The animals (male and female) received orally a 75 mg/kg, 150 mg/kg and 300 mg/kg of the extract for subchronic intoxication evaluation by daily exposure along of 28 days. In the acute toxicity evaluation were used female mices that received an only dose of 300mg/kg and 2000 mg/kg of the extract and observed during to 14 days. Pharmacological tests were conducted to check the possible action of the extract in central nervous system in male mices submitted to 200 mg/kg, 400 mg/kg and 750 mg/kg by oral, subcutaneous and intraperitoneal ways. The animals showed some signs of neurotoxicity whose intensity was proportional to extract concentration and died with oral dose of 2000 mg/kg. Hematological parameters did not showed any significant abnormalities. Biochemical tests did not presented any changes, except ALT and AST measures which presented significant increases in exposed groups in relation to control group. Concerning histopathological exam it was possible to detect lesions that suggest the existence of injuries in liver (microvacuolization and hyperemia) and kidney (hyperemia and hemorrhage). Thus, it can be concluded that ethanolic extract of Aspidosperma subincanum is toxic orally, both acute and subcronically, in mices and the estimated median lethal dosis (LD50) was below 2000 mg/kg.Item Avaliação eletrocardiográfica contínua 24 horas (ecg-holter) durante o período perioperatório em cães(Universidade Federal de Goiás, 2012-08-29) Jacobina, Gabriel Costa; Damasceno , Adilson Donizeti; http://lattes.cnpq.br/3900110295277130; Farias, Anderson; http://lattes.cnpq.br/0842230565580053; Moreno, Juan Carlos Duque; http://lattes.cnpq.br/8509640024284103The ambulatory electrocardiography (ECG-Holter) is a method to obtain the electrocardiographic tracing continuously, noninvasively for prolonged periods (24 hours). Changes in cardiac conduction and arrhythmias can be observed frequently during the perioperative period (pre, during, and post), however this tends to be more careful monitoring before and during surgery. It was shown that there is always the risk of arrhythmias in the postoperative period, but there are few studies in dogs detecting and comparing the electrocardiographic changes during the perioperative period. In this work, we intend to perform a more comprehensive evaluation by electrocardiographic monitoring during the periods before, during and post-anesthesia using the electrocardiogram continuous 24 hours (ECG-Holter) in dogs. It were used 23 dogs underwent to elective surgical procedures and allocated into three groups, young dogs or young adults (GAS), dogs with cardiac disease (GCP) and older dogs (GAI). There were no clinically significant changes in the variables evaluated during the trans-anesthetic. There were no statistical differences between the quantities of arrhythmias observed in the three groups and at different times. However, a greatest number of EV EVS were observed in GAI, especially in the post-anesthetic evaluation. A dog of GAI showed large amounts of ventricular arrhythmias caused by a hidden heart disease. There was no significant difference between the FC (max, min and mean) and HRV between the groups. The atrioventricular blocks (1 and 2) occurred in some dogs in three groups and were mainly observed at night in the pre-and post-anesthetic evaluations and few minutes after anesthetic induction. In conclusion, the anesthetic protocols used proved to be safe and cause few complications in dogs during the trans-anesthetic ECG-Holter monitoring proved to be practical, easy to use, and important for the perianesthetic evaluation in dogs.Item Goniometria em cães da raça Rottweiler(Universidade Federal de Goiás, 2009) Mendonça, Giselle Bonifácio Neves; Alves, Rosângela de Oliveira; http://lattes.cnpq.br/5593911382353878; Silva, Olízio Claudino da; http://lattes.cnpq.br/7787082855013504Goniometry has been used in canine orthopedics to assess clinics, surgical and/or therapy physical treatment efficacy involving shoulder, elbow, carpal, hip, stifle and tarsal. However, in dogs this procedure is few studied and validated to scientifics researches. The purposes of this experiment were to estimate the maximum flexion and extension angle of shoulder, elbow, carpus, hip, stifle and tarsus and carpus adduction and abduction in dogs with breed Rottweiler, compare goniometric joint measurements obtained from no sedated, sedated and measurements made in radiography, and compare this goniometric joint measurements between males and females. The goniometric assess was accomplished by universal plastic goniometer, in 11 dogs Rottweilers, clinically healthy, in Goiânia-GO. One examiner accomplished assess, tree times, in each joint position (flexion and extension of shoulder, elbow, carpal, hip, stifle and tarsal, as well as carpus adduction and abduction) before and after dogs sedation. Also, accomplished measurements from radiographs taken of these joint positions while dogs were sedated, totalizing 1386 measurements. To compare the joint goniometric measure mean of animal nonsedated, sedated and radiographs was used the Friedman test. To compare the goniometry between males and females was used the t test. The differences were considered significant at values of p 0,05, for all comparisons. The results indicated that joint measurements did not differ significantly when compared goniometric measurements in nonsedated dogs, sedated and radiographs, for all joints positions evaluated, exception for shoulder and stifle extension and carpus adduction. Also, no significant differences were identified between the sexes, exclusion the shoulder extension in sedated dogs and carpus abduction in radiographs taken.Item Resultados produtivos no incubatório e na granja de frangos de corte utilizando sistema de incubação em estágio múltiplo e estágio único(Universidade Federal de Goiás, 2013-04-02) Mesquita, Mariana Alves; Gonzales, Elisabeth; http://lattes.cnpq.br/5436760646498130; Leandro, Nadja Susana Mogyca; http://lattes.cnpq.br/3136809931691012; Arnhold, Emmanuel; http://lattes.cnpq.br/7156945506134934The aim of this study was to compare the incubation systems in multiple stage and single stage, by evaluating the performance of the incubation process and the production performance of broilers originated from embryonated eggs incubated in the both systems. To evaluate the yield of incubation five experiments were performed, using eggs of Cobb broiler breeders. Each test was divided into two phases. In the first experimental phase, eggs weight, chicks weight, residual yolk weight, length and quality score of the chicks were analyzed using randomized block design with two treatments (single stage and multiple stage), and with blocks being each experimental trial. In each test, 140 eggs and all the chicks borned from those eggs from each treatment were assessed (experimental unit). In the second phase of the trial, a total of 25.360 eggs and was incubated and spread on trays for analysis of hatchability, hatch window, birth distribution and embryo diagnosis. For hatchability data and hatch window, a randomized block design in a 2x3 factorial arrangement (two incubation systems and three positions of the trays into the incubation machine) was used. The repetitions were composed by the trays, totaling 285. For the results of embryo diagnosis all unhatched eggs from 285 selected trays were evaluated. The productive performance was evaluated until 35 days of age by means of a completely randomized 2x2 factorial arrangement (chicks from two stages of incubation and both sexes), with six replicates. Each experimental unit consisted of 25 birds, totaling 600 birds. We concluded that incubation of fertile eggs from Cobb 500 broiler breeders in single stage machines enables to obtain better productivity of the hatchery than incubation in multiple stage machines, as a result of higher hatchability and better neonate quality. The productive performance of broiler up to 35 days of age was not affected by the type of machine used for incubation.Item Salmonella sp. em frango e ambiente de abate(Universidade Federal de Goiás, 2012-02-29) Oliveira , Aline Pedrosa de; Andrade, Maria Auxiliadora; http://lattes.cnpq.br/9441751521255467; Mesquita, Albenones José de; http://lattes.cnpq.br/3180029815183858; Rezende, Cintia Silva Minafra e; http://lattes.cnpq.br/5841210447886226Poultry food products are identified as being important backers of Salmonella sp. and cause of salmonellosis, which can occur all over the world. In consequence of the impact of this agent to public health and the economy, its monitoring and control should be established in poultry slaughtering. In relevance has been observed the emergence of resistant strains isolated from food to antibiotics in treatment failures reflect the lack of effective response to the principle of the pathogen antimicrobial elected. In this context, the aim of this work was to verify the occurrence of Salmonella sp. in broilers slaughtered in 15 batches from four industries of the state of Goias. The plots were composed of six different samples of carcasses, hearts, gizzards, livers, defeathering and evisceration gutters, using the methods conventional bacterial isolation and enzyme immunoassay VIDAS® for investigation. The susceptibility profile of isolates was determined. Observed the occurrence of Salmonella sp. in 53.33% (8/15) of the lots analyzed and it was found that among the 300 samples analyzed, 21 (7%) were contaminated by the agent. Samples of heart and gizzard showed a higher positivity rate (8.90%), followed by carcass samples (8%), evisceration gutters (6.70%), liver and defeathering showed lower percentages of isolation (4.45 %). In all categories of samples was the isolation of the pathogen, which characterizes the presence of the agent in food and environment slaughter and processing of poultry products. The most frequently isolated serovar of Salmonella Schwarzengrund was (22.41%), followed by serovars Salmonella Cerro (20.69%) and Salmonella Typhimurium (20.69%), Salmonella Livingstone (10, 34%), Salmonella Infantis (5.17%), Salmonella Enteritidis (3.45%), Salmonella Mbandaka (3.45%), Salmonella Saintpaul (3.45%), Salmonella Anatum (1.72%), Salmonella O: 9.15 (1.72%), Salmonella Ohio (1.72%) and Salmonella reacted, but did not conform RDNC (5,17%). Profile of antimicrobial susceptibility, it was observed that 100% of the strains were resistant to erythromycin, 56,89% to nalidixic, 13,79% enrofloxacin, 6,90% to cefotaxime, 3,45% cephalothin and cefoxitin, none of the strains were resistant to sulfazotrim and chloramphenicol. It was observed that 35 (60.34%) were resistant to more than one rule, and one of the isolates was resistant to six of the eight principles antimicrobials. By this results, obtained by evaluated plots, it can concluded that poultry food “in natura” realeased to contain Salmonella consumption, it is also present in the environment of slaughter. This finding supports the need for monitoring food consumption and the environment slaughtering of broilers. Isolates strains denoted different profiles of susceptibility to antimicrobials, occurring multiple resistance and cross-resistance to be considered when evaluated the risk of pathogen in foods.Item Resistência das raças bovinas nelore, curraleiro-pé-duro e pantaneiro a intoxicação experimental por palicourea marcgravii a. St. Hil.(Universidade Federal de Goiás, 2013-08-29) Serodio, Juliana Job; Fioravanti, Maria Clorinda Soares Fioravanti; http://lattes.cnpq.br/8772502020076257; Brasil, Percilio Passos; http://lattes.cnpq.br/4728499090629654; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194The study aimed to evaluate bovines from different brazilian breeds that were submitted to experimental intoxication to Palicourea marcgravii A. St. Hill. Six animals from Nelore (G1), Curraleiro Pé-Duro (G2) and Pantaneiro (G3) breeds were used in the groups. The animals were experimental intoxicated with sodium monofluoracetate acid receiving one single dose of the compound in a dosage of 0,5kg/mg that was administered orally. In order to evaluate the animals, several exams were proceeded such as clinical (rectal temperature, heart and pulmonary rate and ruminal motricity),laboratorial (glucose, alcaline phosphatase, gamma glutamyl transferase, aspartase aminitranferase, creatinine, kinase, creatine, urea, bilirubin, total protein, albumin, globulin) and also histopatological examination. The bovines from G1 showed the first clinical signs between 4h28min and 5h55min and the whole group died after. First clinical signs presented by the G2 animals were between 2h45min and 4h05min after the plant was administered culminating in death of all animals. The main clinical signs observed was inapetence, jugular was dilated, tachycardia, tachypnea, paddling movements, vocalization, hypertermia and low ruminal motricity. The hematology and ALP results showed normal parameters in their results. However, GGT, bilirubin, urea and albumin showed relevant alterations that confirmed azotemia in animals that belonged to G1 and G2. Histopatology results showed multifocal citoplasmtic macrovacuolization and nuclei presenting picnose in epithelial cells from the convoluted tubules. The lesions that were found in the bovines kidneys’ were able to prove the efficacy of the intoxication protocol. The lower indexes of death were identified in Curraleiro Pé Duro bovines showing the greater resistency when compared to Nelore and Pantaneiro breeds. The shortest time interval between the plant intake and death suggest that Pantaneiro breed is more sensitive than Nelore and Curraleiro Pé Duro breeds.Item Ocorrência de Campylobacter spp. em carne de frango(Universidade Federal de Goiás, 2012-03-29) Trassi, Agna Miranda Castro; Mesquita, Albenones Jose de; http://lattes.cnpq.br/3180029815183858; Andrade, Maria Auxiliadora; http://lattes.cnpq.br/9441751521255467; Rezende, Cíntia Silva Minafra e; http://lattes.cnpq.br/5841210447886226The Campylobacteriosis is a zoonosis of worldwide distribution, being Campylobacter jejuni the principal agent etiologic of gastroenteritis cases in humans. The presente study was check for the presence of Campylobacter spp. in carcasses and giblets of poultry, evisceration and depenadeira of three agribusiness located in Goiás State, subject to state inspection service (SIE). 160 samples were analysed from broiler slaughterhouses (A, B, and C), between the months of March and June 2011.Used the technique of conventional bacterial isolation. The positivity was found in 12.5% C. lari e C. jejuni) for liver, 12.5%(C. jejuni) for heart and 4.17% (C. lari) for gizzards. In analyses of the evisceration,broiler carcasses and depenadeira not detectedany samples positive. Through this study noted high exposure to the pathogen, since among the 160 samples analysed 7 (4.37%) contained the bacteria, giblets of poultry larger related edible risk exposure of the consumer population of this class of food.
