Two experiments were carried out to evaluate the use of quaternary ammonia on Salmonella Enteritidis inoculated in eggshell and its penetration capacities, verify the ability to infect the egg inoculated in eggshell, determine embryo mortality, infect hatched chicks and affect incubation parameters of two broiler lines. A total of 302 and 290 fertile eggs of Ross and ISA Label, respectively, were distributed in six treatments: eggs sanitized with placebo (Treatment 1- PC) quaternary ammonia inoculated with Salmonella Enteritidis (Treatment 2-PI); eggs non-sanitized and inoculated placebo (Treatment 3- NPC) with Salmonella Enteritidis (Treatment 4- NPI); eggs inoculated in allantoidal cavity with placebo (Treatment 5-CAC) or Salmonella Enteritidis (Treatment 6- CAI). Immediately after inoculation, the eggs were hatched and embryo mortality was evaluated after 96, 432 and 528 hours. The qualitative results were analyzed by non-parametric tests of chi-square and Kruskall-Wallis. The incubation parameters were not affected when the pathogen was inoculated in eggshell. It was observed that Salmonella Enteritidis inoculated in allantoidal cavity determined late embryo mortality in fast 17,02% and slow growing 13,04% lines, and eggs inoculated in allantoidal cavity originated chicks with high frequency of intestinal colonization by Salmonella Enteritidis of 76,67% and 26,67% Ross and ISA Label, respective.

Thirty six Nelore bulls with age between 30 and 120 months were used to evaluation of the seminal quality and the reproductive aptitude. The animals had been kept in extensive conditions, with feeding the grass, receiving mineral supplementation and serving a herd with 3,782 females of some categories (heifers and cows). Data enclosed measured of scrotal circumference and evaluation of the semen collected by eletroejaculation and evaluated the physical characteristics (volume, mass activity, motility, strong), morphologic (major, minor and total defects) and spermatic structure integrity (integrity of plasmatic membrane, acrosome and chromatin) in this period had been carried through that preceded three consecutive mating season (2003, 2004 and 2005). The data had been submitted analyze of variance, the averages compared for test SNK and the coefficient of correlation of Pearson was calculated using the SAS. The bulls presented scrotal circumference of 33.8 ± 2.8cm, 15.6 ± 8.5% of total spermatic defects, 40.1 ± 23.1% of gametes with normal membrane and acrosome and 8.8 ± 3.8% of fragmented chromatin. The relations between scrotal circumference, physical and morphologic characteristics, spermatic integrity and the reproductive performance of the herd had been low and not significant (P< 0.05). In sexually mature bulls the integrity of plasmatic membrane, acrosome and nuclear chromatin had not been the most frequent trouble of the spermatic morphology.

The subclinical mastitis is a mammary gland inflammatory reaction that is characterized by increased levels of somatic cells in the milk. The milk with higher somatic cell counting (SCC) shows alteration in the composition that alters the quality of the milk products. This study aimed to evaluate the effects of the SCC in the milk products in relation to the microbiologic and the physical-chemistry features of the mozzarella cheese. It was chosen cattle with SCC 200.000 cells/mL; SCC >200 a 400.000 cells/mL; SCC >400.000 cells/mL to 750.000 cells/mL and SCC >750.000 cells/mL. The animals did not receive antimicrobial treatment before and on the day of the milk collection. The mozzarella cheese preparation were realized at Planta de Laticínios do Centro de Treinamento da Agência Rural. It was analyzed the milk sub products compositions. The cheese were evaluated after 1, 15 and 30 days of maturation or storage at 7°C for the pH, acidity, humidity, total and soluble protein, fat, total dry extract, defatted, milk acid bacteria count, total and fecal coliforms and psicotrofics microorganism. The experiment was repeated four times in order to demonstrate reproducibility. The results were homogenous for the residues (turkey test) and the variances were compared using a F test, adopting =0,05. The milk with high SCC showed low concentration of protein and the higher nitrogen levels. There was loosing of protein and fat to serum. The cheese elaborated from milk with higher SCC (>750.000cells/mL) showed lower protein level, more humidity and less industrial income and presented lower growth of lactic acid bacteria during the maturation time. Mozzarella cheese prepared with milk containing SCC around 400.000 cells/mL presented increased proteolysis. The results showed here demonstrated that in order to get a good quality mozzarella cheese is necessary the utilization of the milk with somatic cell counts bellow 400.000 cells /mL
Lesões de isquemia arteriovenosa e reperfusão em jejuno de equinos: imunoistoquímica de proteínas de junção e histopatologia
(Universidade Federal de Goiás, 2007-12-31) NASCIMENTO, Aline Machado Rapello do; ARAÚJO, Eugênio Gonçalves de; http://lattes.cnpq.br/3919777570059928; BRITO, Luiz Augusto Batista; http://lattes.cnpq.br/3212353728321020
To evaluate whether complete arteriovenous ischemia followed by reperfusion of mesenteric blood flow aggravates lesions involving small intestine of horses, β--catenin and occludin expressions were measured in jejune epithelia of seven equines, without definite breed. The animals had been submitted to aseptic ventral midline celiotomy and five jejune segments collected corresponding to a baseline segment, a five minutes segment subjected to ischemia, and three segments collected after being subjected to five, sixty and one hundred and twenty minutes of tecidual reperfusion, respectively. Experimentally induced lesions created by total arteriovenous occlusion followed by reperfusion were similar to naturally acquired lesions, as much in the period of ischemia as in the aggravation of the injuries observed during reperfusion. Changes that occur when ischemic intestine is reperfused are progressive, and include mucosal, submucosal, and serosal edema; polymorphonuclear and mononuclear cell infiltrates; and alterations in vascular patterns. Imunohistochemistry analyses have shown strong staining baseline segments for β-catenin in all animals and its progressive lack of staining during ischemia and reperfusion treatments. That indicates progressive lack of intercellular adherence. Similar results of specific decreases of total expression of Occludin, a tight junction protein, were observed. This protein is involved in regulating the movement of solutes in the paracellular pathway and also plays an important role in the maintenance of cell polarity. The reduction of expressions of both intercellular proteins measured directly demonstrates β-catenin injury due to progression of edema during ischemia and its aggravation during reperfusion and also shows an increase of the permeability of paracelular pathways and its related consequences to degradation of Ocludina.

(Universidade Federal de Goiás, 2008-02-28) LIMA, Aline Maria Vasconcelos; ARAÚJO, Eugênio Gonçalves de; http://lattes.cnpq.br/3919777570059928; BRITO, Luiz Augusto Batista; http://lattes.cnpq.br/3212353728321020; CHAVES, Nilo Sérgio Troncoso; http://lattes.cnpq.br/9218281815823682
Considering the relevance of tear production and tear quality to the conservation of the corneal health, the present study aimed to evaluate tear production and conjunctival goblet cells density in Shih-tzu dogs. Thirty five grownup Shih-tzu dogs, including 33 females and 2 males, were subjected to Schirmer tear test 1 (STT-1) and Schirmer tear test 2 (STT-2). Among these dogs, fourteen females and one male were underwent to conjunctival biopsy for histologic evaluation of goblet cell density (GCD) and goblet cell index (GCI). The STT-1 mean values found were 19,66 ± 7,3 mm/min for left eye (LE) and 21,97 ± 5,7 mm/min for right eye (RE). The STT-2 mean values were 10,71 ± 6,1 mm/min and 9,14 ± 4,78 mm/min for LE and RE, respectively. The GCD mean values found were 13,64 ± 3,44 goblet cells/50 epithelial cells for LE and 13, 64 ± 4,07 goblet cells/50 epithelial cells for RE. The GCIs correspondent were 0,27 ± 0,069 and 0,27 ± 0,081 for LE and RE, respectively. There was significant difference between LE and RE STT-1 values. There was not significant difference between eyes for STT-2, GCD and GCI values. STT-1 and STT-2 values did not influence significantly GCI values. STT-1 and STT-2 values are within of the pattern considered normal, but the GCD and GCI mean values are lower than those values described in literature for healthy dogs of other breeds. The conjunctival specimens histological evaluation was accepted as convenient, which demonstrated squamous metaplasic areas in 83,3% of the specimens. Within 44% of these, squamous metaplasia was predominantly associated with mononuclear inflammatory infiltrate.
Imunofenotipagem e avaliação quantitativa de linfócitos circulantes de bovinos da raça curraleiro
(Universidade Federal de Goiás, 2008-03-03) MORAES, Júlia de Miranda; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; BRITO, Luiz Augusto Batista; http://lattes.cnpq.br/3212353728321020
The Curraleiro cattle are extremely docile and resistant to infectious diseases and parasites. They may be used in exploration of low-quality pastures, without great investments, when other breeds could show a low productivity or even survival difficulties. This genetic potential runs risk to extinction due to its replace by more productive breeds. The Curraleiro cattle resistence to illness is popularly known and many works has been published about it, although its immunologic system physiology is completely unknown. Such features are plausible reasons for the preservation of this potentially genetic resource. So, the mean aim of this study was to establish an immunological profile by marking and quantification of T and B lymphocytes in Curraleiro breed with immunocytochemistry. Thus, it was used 116 bovines, male and female, with different ages from two farms situated at Goiás State, Brazil. The animals were allotted in groups according to age, sex and origin. Blood samples were collected and processed in accordance with immunocytochemistry standard technique using lymphoid markers species-specific, anti-CD3 (MM1A BoCD3) and anti-LB (LCTB16A clone B-B14), for T and B lymphocytes counting, respectively. All procedures were accomplished at Veterinary School, Federal University of Goiás, Brazil. The data were submitted to descriptive statistics and then to Kruskall Wallis and Mann-Whitney tests. The results showed decreased levels of leukocytes, lymphocytes, T lymphocytes and B lymphocytes along the age advance. Absolute values of leukocytes, lymphocytes and T lymphocytes were higher in males than females. None of the evaluated parameters were affected by differences of the management carried out at two farms.
ANESTESIA COM CETAMINA S(+) ASSOCIADA À ATROPINA E XILAZINA EM CÃES: AVALIAÇÃO CARDÍACA E BIOQUÍMICA SÉRICA
(Universidade Federal de Goiás, 2008-03-05) FRANCO, Leandro Guimarães; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; SILVA, Luiz Antônio Franco da; http://lattes.cnpq.br/0446055905975647
Changes in physiological parameters of electrocardiography, echocardiography and biochemistry markers were evaluated in dogs anesthetized with different associations of atropine, xylazine and S-ketamine. Twenty three healthy female dogs randomly distributed in four groups named as GI-6, GII-6, GIII-6 and GIV-5 were treated respectively with atropine and S-ketamine (0,04mg/kg; 10 mg/kg); S-ketamine (10 mg/kg); atropine, xylazine and S-ketamine (0,04mg/kg; 1,1 mg/kg; 10 mg/kg) and xylazine and S-ketamine (1,1 mg/kg; 10 mg/kg). Ten minutes after induction, 5mg/kg of S-ketamine was administered to animals from all groups. Measurements of electrocardiogram, echocardiogram and serum activity of aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase MB isoenzyme (CK-MB) were evaluated for 36 hours. Concerned to electrocardiography, the proposed anesthetic protocols showed significant changes especially in atrioventricular conduction period (PR interval) and systole period (QT interval), mostly in GIV. In relation to echocardiography, the main alterations happened in following variables, final stroke volume, ejection fraction and cardiac output, predominantly in GIV. In serum biochemistry analysis, it was observed alterations in CK and CK-MB values in all groups, which maintained changed for a longer time in GIII and GIV. Thus, under conditions of this study, it can be conclude that atropine, xylazine and S-ketamine association (GIII) determined lower effects on heart, while marking alterations occurred in animals from GIV

It was the objective of this study to evaluate the performance and reproductive parameters of different genetic groups of japanese quails between six and 26 weeks of age. There were used 384 japanese quails, assigned according to the experimental design (ramdomized blocks), considering the initial live weight of the birds as blocks in the beginning of the experiment. The treatments were three genetic groups with eight replicates, in a total of 48 experimental units with eight birds in each experimental unit (two males and six female). The birds were fed rations according to recommendations of NRC (1994), having soybean meal and ground corn as the main components. The variables of performance were studied every 14 days and three incubation trials were done with 15, 24 and 33 weeks of age. For the statistical analysis the proc GLM of SAS software was used and the means were compared by the t Student test. In each incubation study the completely ramdomized blocks experimental design was used, considering the incubating machines as blocks, with 70 replicates per treatment and one egg as the experimental unit. The parameters evaluated were the egg weight, hatchability, chick weight at hatching, weight loss and weight after six hours of fasting. The results were submitted to variance analysis and the means compared by the t Student test (5% of probability). The genetic groups presented differences among each other for the live body weight in the beginning of production, age at 50% of of productiontwere different to body weight at the beggining and age at 50% of production, where the commercial parent line obtained the best performance. The parameters peak persistence, eggs production, feed intake, viability and beak behavior did not present differences among the genetic groups. The live body weight influenced the egg weight. In the incubation trials the commercial parent line presented more weight of the incubating egg and more weight of the chicks at hatching. It was concluded in the present study that there are statistical differences on the performance and incubating parameters among genetic groups of japanese quails.
Componentes sanguíneos de bovinos (Bos taurus) da raça Pantaneira em diferentes faixas etárias, criados extensivamente

The Pantaneiro cattle reveal docility, resistance to illnesses and parasites, and an incredible ability to adapt to Pantanal's edophoclimatic conditions. The cattle may be used without considerable investment to explore low-quality natural pastures in which other breeds might endure low productivity or even survival difficulties. Thus the determination of the normal blood constituents of Pantaneiro bovines was set in order to reveal further information regarding the physiological aspects of these animals. Therefore 293 blood samples were collected from two rural properties, one from Mato Grosso and the other from Mato Grosso do Sul. These individuals were classified in five groups according to their age group, as follows: G1, G2, G3, G4, and G5. The parameters under investigation were the erythrogram and the leukogram. Initially the data was submitted to descriptive statistics which included the determination of averages, standard deviation, and coefficients of variation. Subsequently data was submitted to the Kruskall Wallis test in order to establish the age relationship and to the Mann-Whitney test in order to establish the sex relationship. Age advancement revealed an increase in MCV, MCH, and in the number of eosinophils. Age advancement showed a reduction in the number of red blood cells, hemoglobin, MCHC, segmented neutrophils, and band neutrophils. The values of globular volume and monocytes revealed a rising behavior up to 35 months of age and subsequently suffered a reduction as age advanced. The values of lymphocytes and total leukocytes presented a rising behavior up to 11 months of age and a subsequent decline as age increased. The results of this research failed to show any relations between hematological parameters and the sex factor

Idade da matriz e período de armazenamento de ovos incubáveis no rendimento de incubação e desempenho inicial de poedeiras comerciais
(Universidade Federal de Goiás, 2008-05-21) TANURE, Candice Bergmann Garcia e Silva; LEANDRO, Nadja Susana Mogyca; http://lattes.cnpq.br/3136809931691012; CAFÉ, Marcos Barcellos; http://lattes.cnpq.br/9860968235125158
Two experiments have been carried out to evaluate the effect of the breeder hen ages and of the storage period of the eggs over the incubation efficiency and initial performance of laying hens. In the first experimental phase, 7224 Dekalb eggs with 32 and 57 weeks old, were incubated with three, five and seven days of storage. The treatments were defined according to the breeder hens ages and their period of storage of eggs, summing up to six treatments with fourteen repetitions of treatment each. The statistical outline was random and the tray height was a covariable. The efficiency of the incubation, the eggs loss of weight during storage, the quality of incubated eggs and the absolute weight of the yolk sac in relation to the weight of the chicken was evaluated. On the second experimental phase, 600 chickens from the six treatments of the first experimental phase were used. The poultry were bred up to the 28th day of life in common batteries. The statistical outline was totally random, and the height of the batteries was a covariable, with five repetitions of twelve birds in each treatment. The starter performance of chicks (up to 28 days of life) was evaluated. The results were submitted to variance analysis and to verify the importance of differences between the average of treatments, the Tukey test was used, with a probability of 5%. The breeder hens of 57 weeks produce heavier eggs with a larger quantity of albumen and yolk. The old breeder hens eggs had a lower quality of albumen when stored for seven days. The loss of weight of the eggs during storage and removal was higher according to the aging of the breeder hen. Eggs produced by the young breeder hens had a higher hatching rate; however, no matter the age of the breeder hen, there was a decrease of the hatching rate of fertile eggs whenever the storage period was increased. The breeder hens with 57 weeks produced heavier chicks and lower chick/egg weight coefficient. The higher ratio yolk sac/chick weight was obtained by the eggs produced by the old breeder hens. There was a lower weight loss of chicks from young breeder hens during the removal of incubatory trays to the grange. The storage period did not interfere in the birds performance and birds from old matrixes presented worse uniformity, higher final weight and bigger food allowance
FLUIDOTERAPIA AQUECIDA NO CONTROLE DA HIPOTERMIA EM CADELAS SUBMTIDAS A OVARIOHISTERECTOMIA SOB ANESTESIA INALATÓRIA

Hypothermia is a frequent event in the per-operative period. Usually neglected in Brazil, it may lead to complications such as delay on anesthetic recovery, blood gas impairment, brain and myocardial ischemia and postoperative shivering. Prevention of hypothermia includes aspects from hospital facilities to training the nurse team. Heated fluid infusion is an aid on maintaining body temperature. A recent release of Brazilian industry, the SAF® Fluid Heating System, is a device which maintains warm the fluid to be infused, intended to reduce risks related to per-operative hypothermia. The following study aimed to evaluate clinical and electrocardiographic parameters, blood gas analysis, and serum biochemistry of female dogs submitted to elective ovariohysterectomy and infusion of 0,9% saline solution heated at 37ºC by SAF®. Thirteen female dogs were allocated in two groups: GI control (n=6), and GII treatment (n=7), in an operating room acclimatized at 22ºC. The parameters were evaluated along 90 minutes from pre-anesthetic medication. There were no significant clinical or biochemical variations; however there was group effect on the variables mean arterial pressure, urea, ALT, ALP and hypnosis time. There was no expressive variation on blood gas analysis, although some variables presented significant differences along the moments, but not between the groups. Electrocardiographic significant alterations were not evident, except for P wave, indicating atrial overload in GI. The isolated use of SAF®, on the conditions and degree of hypothermia of this study, was not enough to avoid hypothermia in female dogs submitted to general inhalatory anesthesia.
PERFIL SANITÁRIO DE BOVINOS DA RAÇA CURRALEIRO FRENTE A ENFERMIDADES DE IMPORTÂNCIA ECONÔMICA
(Universidade Federal de Goiás, 2008-06-20) SANTIN, Ana Paula Iglesias; KIPNIS, Ana Paula Junqueira; http://lattes.cnpq.br/1252262903952987; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; BRITO, Wilia Marta Elsner Diederichsen de; http://lattes.cnpq.br/7605775995731168
Com o objetivo de ampliar os conhecimentos sobre os aspectos sanitários de bovinos da raça Curraleiro, foi realizado o estudo comparativo entre animais Curraleiros e outras raças bovinas (Guzerá, Nelore, Girolando e Caracu), em relação a enfermidades de importância econômica e epidemiológica para pecuária. Para tanto avaliou-se a ocorrência de eventual diferença no perfil sanitário destes animais através de pesquisa de anticorpos para B. abortus, Leptospira spp, Neospora caninum, Toxoplasma gondii, vírus da leucose enzoótica bovina (BLV), herpesvírus bovino-1(BHV-1), vírus da diarréia viral bovina (BVDV) e realização de reação intradérmica para Mycobacterium bovis. As fêmeas bovinas eram provenientes de propriedades localizadas em Goiás e Tocantins e na região de divisa entre Goiás, Minas Gerais e Bahia (Trijunção). Em relação às doenças bacterianas, nenhum dos animais foi reagente para brucelose e tuberculose. Por outro lado, todas as propriedades estudadas apresentaram animais sororreagentes para Leptospira, N. caninum, T. gondii, BLV, BHV-1 e BVDV. Ao se comparar o Curraleiro com as outras raças separadamente, verificou-se para leptospirose que houve um número significativamente maior de animais sororreagentes da raça Guzerá. Em relação à neosporose os Curraleiros apresentaram um número significativamente maior de bovinos sororreagentes do que a raça Guzerá e Nelore. Resultado semelhante foi observado na toxoplasmose ao se comparar o Curraleiro com o Caracu. Para as demais enfermidades a resposta sorológica foi semelhante entre os Curraleiros e as outras raças. Para leucose enzoótica bovina ainda foram avaliados os níveis de proteínas totais, de frações protéicas, além da contagem de leucócitos e linfócitos, sendo os resultados comparados entre animais reagentes e não reagentes ao BLV, independente da raça. No entanto só foi observada diferença significativa em relação à gamaglobulina que encontrava-se aumentada em bovinos sororreagentes e os linfócitos, que apesar de apresentarem-se dentro dos padrões considerados normais estavam com níveis mais elevados nos animais soropositivos
SUBSTITUIÇÃO DA SILAGEM DE CANA-DE-AÇÚCAR PELA SILAGEM DOS RESTOS CULTURAIS DO ABACAXIZEIRO NA ALIMENTAÇÃO DE RUMINANTES

The objective of this trial was to study the substitution of sugar cane silage + 0,5% urea (SCS) by the pineapple stalk silage (PSS) on the feed ruminants. The trial was done in Goiânia-GO and lasted 95 days. Five non castrated male lambs from Santa Inês breed were utilized, with an average age of eight months and live weight of 30,2kg ± 4,8kg. The experimental design was a 5x5 Latin Square, the diets were isoproteic (13,5% CP) and isoenergetic (63% TDN) and the forage:concentrate ratio was 60:40. The parameters evaluated were the dry matter intake (DMI) and relative voluntary intake (RVI), apparent digestibility of nutrients, nutritive value index, physically effective fiber, rumen pH and rumen kinetics. The treatments were the following: 100% PSS:0% SCS (100P); 75% PSS:25% SCS (75P); 50% PSS:50% SCS (50P); 25% PSS:75% SCS (25P) and 0% PSS:100% SCS (0P). There were no differences (P>0,05) among treatments for the DMI (597,27 g/day) and RVI (58,41 g of MSU/day). The dry matter digestibility (DMD) and neutral detergent fiber digestibility (NDFD) did not differ (P>0,05) among diets. The crude protein digestibility (CPD) increased when SCS was linearly added, whose values were 68,09%; ,57%; 70,68%; 73,06% and 78,05%, respectively for the treatments 100P, 75P, 50P, 25P and 0P, which can be explained by the addition of 0,5% urea when the sugar cane was ensiled and characterizing the presence of non protein nitrogen (highly soluble in the rumen). It was not verified differences for the nutritive value index (NVI) among treatments, where the mean was 37,74%. Probably due to the DMI and DMD did not present differences (P>0,05) among treatments. Regarding the physically effective fiber (peNDF), there was not effect among treatments and the mean value was 25,92%. There was reduction in the ruminal digesta dry matter disappearance (%/h) with increasing addition of SCS. The values for this parameter were 8,08%/h; 8,31%/h; 5,85%/h; 6,49%/h and 7,03%/h respectively for the treatments 100P, 75P, 50P, 25P and 0P. Since there was no effect in the DMI among treatments and the ruminal digesta dry matter disappearance in the treatments having PSS was higher, it can be concluded that the dry matter digestion rate of the PSS was also higher. The rumen pH increased linearly with addition of SCS, where the values for the treatments 100P, 75P, 50P, 25P and 0P were respectively 6,16; 6,16; 6,33; 6,42 and 6,63. Based on the nutritive value it can be concluded that the sugar cane silage + 0,5% urea can be substituted by the pineapple stalk silage

The state of Goias has the third largest cattle herd in Brazil, but the production has some obstacles, such as reproductive diseases, which cause abortions and infertility, including leptospirosis, also important in public health. This study aimed to determine the prevalence of antibodies against Leptospira spp., determine their regional distribution and evaluate the main risk factors for the disease in cattle in the State of Goias. The study was conducted using the 4571 samples taken from 715 properties of 213 of the 246 municipalities in the state of Goiás The samples were analysed by the microagglutination test. To determine the correlation between the prevalence and associated factors, the test of Logistic Regression was used through the software SPSS. The percentage of positive samples for at least one of the16 serovars tested was 62.2%, with major prevalence of co-agglutination (40.24%), followed by serovars wolffi (14.53%), hardjo (12.70 %), grippotyphosa (10.55%) and shermani (6.55%). The prevalence of antibodies against Leptospira spp. proved to be associated to the following factors: stratum of production, with a greater prevalence in stractum one, predominantly for meat production; practice of artificial insemination; cattle breed; presence of sheep and goats; presence of capybaras; purchase of cattle in breeding exhibitions and from other properties; rent of pastures in any time of year; presence of maternity paddock and occurrence of abortions. On the other hand, it was not found correlation with the following factors: type of exploitation and creation charged in the property; kind of milking; presence of horses, pigs, dogs, cats, deer and other wild animals; presence of other animals; purchase of animal at fairs and/or auctions; selling of cattle in exhibitions, in fairs and/or auctions, from traders or from other properties; presence of pastures in common with other properties, veterinary care and vaccination against brucellosis, IBR and BVD. It was concluded that leptospiral infection is endemic in Goias.
