Foram utilizadas 22 búfalas, distribuídas em dois grupos experimentais: grupo rbST - aplicação de 500mg de rbST a cada 14 dias; grupo Controle - sem aplicação de rbST. A cada sete dias, foram coletadas amostras de sangue para a determinação do perfil bioquímico e mensuraram-se a produção de leite e o escore de condição corporal dos animais. As médias dos parâmetros estudados para os grupos rbST e Controle foram, respectivamente: produção de leite (PL): 6,44kg vs. 6,68kg; escore de condição corporal-ECC (1-5): 3,51 vs. 3,57; glicose: 70,58 vs. 64,81mg/dL (P = 0,0003); colesterol: 132,38 vs. 133,40mg/dL; triglicérides: 29,18 vs. 28,32mg/dL; proteína total: 8,57 vs. 8,75g/dL; albumina: 3,47 vs. 3,60g/dL; ureia: 32,46 vs. 33,86mg/dL; creatinina: 1,27 vs. 1,39mg/dL; cálcio:10,25 vs. 10,73mg/dL; fósforo:5,76 vs. 5,62mg/dL; e magnésio:3,70 vs. 3,70mg/dL. O uso de 500mg de rbSTinfluenciou o metabolismo da glicose, porém não modificou a PL, o ECC e os níveis dos demais parâmetros metabólicos estudados. ABSTRACT The aim was to evaluate the influence of recombinant bovine somatotropin (rbST) on the energy and mineral metabolism of buffaloes between 63 - 154 days in milk. Twenty-two buffaloes distributed in two experimental groups were used: Group rbST (n= 11) - application of 500mg of rbST every 14 days; Control Group (n= 11) - no rbST. Every seven days, blood samples were taken to determine the biochemical profile, and milk production and body condition score were measured. The averages of the variables for rbST and Control groups were, respectively: milk yield (MY) - 6.44kg vs. 6.68kg; body condition score (BCS) - 3.51 vs 3.57 (1-5); glucose - 70.58 vs. 64.81mg/dL (P = 0.0003); cholesterol - 132.38 vs. 133.40mg/dL; triglycerides -29.18 vs. 28.32mg/dL; total protein - 8.57 vs. 8.75g/dL; albumin - 3.47 vs 3.60g/dL; urea - 32.46 vs 33.86mg/dL; creatinine - 1.27 vs 1.39mg/dL; calcium - 10.25 vs. 10.73mg/dL; phosphorus - 5.76 vs 5.62mg/dL; and magnesium - 3.70 vs 3.70mg/dL. Use of 500mg rbST influenced glucose metabolism, but did not modify the MY, BCS and the levels of the other metabolic parameters studied.

Background Bovine tuberculosis (bTB), is a worldwide disease caused by Mycobacterium bovis (M. bovis). The success of bTB eradication and control programs is based on early detection and the removal of reactors from a herd thus routine testing and cull strategy have been applied globally. Since the late nineteenth century, the Tuberculin Skin Test (TST) has been the primary antemortem test available to support bTB eradication campaigns. Due to the TST limitations in terms of Se and Sp, the credibility of the diagnosis is frequently questioned given the occurrence of false-positive and false-negative reactions, therefore, it is necessary to confirm reactive animals using other methods, ensuring the reliability of the diagnosis. The aim of this study was to evaluate the sensitivity and specificity of a multiplex enzyme-linked immunosorbent assay (ELISA) relative to the tuberculin test used for the diagnosis of tuberculosis in cattle in Brazil. Results Lack of agreement between comparative cervical tuberculin test and ELISA IDEXX TM was observed. The 2 animals positive on the comparative cervical tuberculin test did not react at the ELISA IDEXX TM and 22 negative reactors by comparative cervical tuberculin test were positive by the ELISA IDEXX TM. The ELISA IDEXX TM showed sensitivity that is significantly lower than the official screening test the single cervical tuberculin. ELISA IDEXX TM also detected infected animals and herds undetected by the comparative cervical tuberculin test. The parallel use of comparative cervical tuberculin test and ELISA IDEXX TM increased sensitivity and the feasibility bTB screening. Conclusions The results obtained here suggest that the ELISA IDEXX TM may be a supplemental test for the detection of Mycobacterium bovis infection in regions without routine testing and slaughter, where the disease generally progresses to more advanced stages and antibody responses are likely to be more prevalent. Evidence to support the validation of the ELISA IDEXX™ as a supplemental test for bTB eradication programs was provided.

Hyperketonemia in sheep is associated with a disease known as pregnancy toxemia. The purposes of this study were to (1) induce hyperketonemia by infusion with D-beta-hydroxybutyrate (D-BHB) in eighteen healthy, non-pregnant, non-lactating ewes, (2) to evaluate the metabolic pathways in which recombinant bovine somatotropin (rbST) may be involved, and (3) to evaluate the possible benefits of preventive rbST therapy on the metabolic profiles of the sheep. The sheep were intravenously infused with a D-BHB solution over 2 h. Three days prior to the infusion, one group (n = 9) was injected with a single dose of 160 mg rbST, and the other group (n = 9) was injected with saline as a control. Blood samples were collected and metabolic profiles were analyzed every 20 min during the infusion and at 15, 30, 60, 120, 180, and 240 min post-infusion. Hyperketonemia was successfully achieved, demonstrated by serum BHB concentrations of 3.9 and 3.0 mmol/L in the rbST and control groups, respectively, without the presence of clinical signs. An increase in peripheral insulin resistance was observed after infusion but not during the infusion, in the rbST group. Higher glucose concentrations were observed in the rbST group post-infusion, suggesting a positive impact of D-BHB on gluconeogenesis. Our data suggest that prophylactic treatment with rbST may be useful in sheep to reduce the risk of PT.

Objetivou-se avaliar a influência da somatotropina recombinante bovina (rbST) sobre a produção e os constituintes do leite de búfalas entre 63 e 154 dias em lactação. Foram utilizadas 22 búfalas, distribuídas em dois grupos experimentais: grupo rbST - aplicação de 500 mg de rbST a cada 14 dias; grupo controle - sem aplicação de rbST. A cada sete dias, foi aferida a produção de leite de todas as búfalas e coletada uma amostra para análise físico-química. As variáveis produtivas e as oriundas de análises laboratoriais foram avaliadas como medidas repetidas no tempo, utilizando-se o comando Repeated gerado pelo procedimento GLM do SAS. A média dos parâmetros estudados para os grupos rbST e controle foram, respectivamente: produção de leite - 6,54 vs. 6,68 kg; gordura - 6,31 vs. 6,34%; proteína 3,86 vs. 3,81%; lactose - 4,96 vs. 5,02%; sólidos totais - 16,05 vs. 16,03%; extrato seco desengordurado - 9,75 vs. 9,74%; contagem de células somáticas - 329,90 vs. 171,68 (x 1000/mL); e elecondutividade - 2,87 vs. 2,81mS/cm. A utilização de 500mg de rbST administrados quinzenalmente, entre 63 e 154 dias em lactação não alterou a produção de leite, a proporção dos constituintes e a CCS do leite de búfalas leiteiras. This study aimed to evaluate the effect of recombinant bovine somatotropin (rbST) on milk yield and the proportion of buffalo milk components during lactation. Twenty-two buffaloes randomly distributed in two experimental groups were used: Group rbST - application of 500mg rbST every 14 days, between 63 and 154 days in milk (DIM); Control Group - without treatment. Weekly, the milk yield of buffaloes was measured and a sample was collected for physicochemical analysis. The response variables were evaluated as repeated measures, using the Repeated procedure through the GLM procedure of SAS. Means of each variable after rbST and Control were: Milk yield - 6,54 vs. 6,68 kg; Fat - 6,31 vs. 6,34%; Protein - 3,86 vs. 3,81%; Lactose - 4,96 vs. 5,02%; Milk solids - 16,05 vs. 16,03%; Defatted dry matter - 9,75 vs. 9,74%; Somatic Cells Count - 329,90 vs. 171,68 (x 1000/mL); and electrical conductivity- 2,87 vs. 2,81mS/cm. The use of 500mg of rbST administered every two weeks, between 63 and 154 DIM did not affect milk yield, proportion of milk constituents and SCC of dairy buffaloes.

The relationship between body maturation at puberty and pregnancy after fixed-time AI (FTAI) was investigated in young Nelore (Bos indicus) heifers. Heifers (n = 650; 13.9 ± 0.03 months; 252 ± 0.99 kg LW) were assessed for body condition score (BCS, scale 1–5), withers height (hWITHERS, cm), chest depth (cDEPTH), subcutaneous fat thickness (SCFT, mm), and the presence of a corpus luteum (puberty). Heifers then underwent a progesterone-based estrus synchronization protocol with FTAI, and pregnancy rate to AI (P/AI) was recorded. Data were analyzed by univariate and multivariate logistic regression using the GLIMMIX procedure of SAS 9.3 and Receiver Operating Characteristic (ROC) curves were used to ascertain the effects of variables on puberty and P/AI. BCS and hWITHERS were not related (P > 0.05) to either puberty or P/AI. cDEPTH had no relationship (P = 0.56) with puberty but influenced (P 3.4 mm attained puberty and the P/AI was greater (P = 0.0003) for heifers with SCFT > 2.5 mm. The findings were interpreted to indicate that both puberty and the response to estrus synchronization-FTAI in young Nelore heifers are dependent on the acquisition of subcutaneous adipose tissue that is sufficient to support reproductive function. It was concluded that Nelore heifers selected and nutritionally managed for body maturation can achieve a pregnancy rate to FTAI at around 14 months of age that is similar with pregnancy rates in older heifers.

The neonatal period is a challenging phase for calves, and during this phase constant adaptations are required. The aim of the present study was to evaluate the invasive hemodynamics with the Swan-Ganz catheter in neonate calves to understand adaptive changes during the first 30 days of life. A prospective and observational study was conducted with 10 Holstein calves. Assessments of the right atrial pressure (RAP), right ventricular pressure (RVP), pulmonary artery pressure (PAP), pulmonary capillary pressure (PW), cardiac output (CO), heart rate (HR), pulmonary vascular resistance (PVR), and blood gas levels were performed. The analyses of PAP, PVR, PW, HR, sO2, and arterial blood gases differed (p <, 0.05) between the evaluated periods. Our results indicated transient pulmonary artery hypertension during the process of extrauterine adaptation during the first 30 days of life. This hypertension must be considered as physiological and consequent to the neonatal adaptation process.

Made available in DSpace on 2018-11-26T17:55:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-08-01 Pregnancy-associated glycoproteins (PAG) are expressed in the placenta of ungulate mammals. Ruminants secrete PAGs continuously from embryonic implantation until delivery. In this study, we evaluated the feasibility of using ELISA to detect PAG levels as a method for early pregnancy diagnosis in Zebu (Nelore) beef cows. We compared the efficacy of this method with transrectal ultrasonography (US) in detecting pregnancy on the 25th and 28th days after timed artificial insemination (TAI) of 130 crossbred Zebu cows. Blood samples were taken during these two time points for PAG determination; ultrasound examinations were also performed on both days. Rectal palpation was used on the 80th day to definitively verify pregnancy. PAG ELISA accuracy was equal across both time points, with 100% sensitivity, 92.86% specificity, 96.70% positive predictive value, and 100% negative predictive value. In contrast, US had 62.50% and 93.18% sensitivity, 95.24% specificity, 96.49% and 97.63% positive predictive value, coupled with 54.79% and 86.96% negative predictive value on the 25th and 28th days, respectively. Thus, the two diagnosis methods differed significantly in negative predictive value and sensitivity, but not positive predictive value or specificity. In conclusion, PAG ELISA was just as specific as US, but more sensitive. Its safety (compared with US and rectal palpation) and high accuracy in identifying nonpregnant cows make PAG ELISA a good option for early pregnancy diagnosis (beginning 25 days post-TAI) in Zebu females.

Objetivou-se com este trabalho descrever as medidas biométricas de cordeiros lactantes da raça Santa Inês criados em condições amazônicas; estabelecer relação entre a idade e as medidas corporais; bem como correlacionar essas medidas biométricas com o peso corporal. Utilizaram-se 75 animais criados em sistema semi-intensivo, submetidos a mensurações do peso corporal (PC), comprimento corporal (CC), altura do anterior (AA) e do posterior (AP), perímetro torácico (PT), largura da garupa (LG) e do peito (LP), comprimento da perna (CP), perímetro da perna (PP) e compacidade corporal (COMPC), ao nascer e aos 15, 30, 45 e 60 dias de idade. Somente as medidas LG e PP demonstraram regressões com R2abaixo de 0,70 em relação à idade dos cordeiros. Todas as medidas corporais utilizadas nesta pesquisa, individualmente, demonstraram r positivo com o peso corporal. As variáveis biométricas que melhor compuseram a equação de predição do peso dos cordeiros utilizados neste estudo foram CC, AP, PT, LG e PP. Concluiu-se que a idade de cordeiros pode ser utilizada como preditora do peso e de algumas medidas biométricas corporais e que o peso pode ser estimado por meio de algumas medidas biométricas. This study aimed to 1) describe the biometric measurements of Santa Inês lambs until weaning, when raised in the Amazonia conditions; 2) establish the relationship between age and body measurements; and 3) correlate these biometric measurements to body weight. 75 animals submitted to semi-intensive breeding were used, and underwent measurements of body weight (BW), body length (BL), height of the forelimb (HF) and hindlimb (HH), thoracic perimeter (TP), width of rump (WR) and chest (WC), length of leg (LL), perimeter of leg (PL) and more body compacity (COMP), at birth and at 15, 30, 45 and 60 days of age. As a result, the WR and PL measurements demonstrated regressions with R2 below 0.70 in relation to age of lambs. All biometrical measurements used in this study individually demonstrated positive r with body weight. Biometric variables that compose the equation for predicting weight of lambs used in this study were BL, HH, TP, WR and PL. It was concluded that the age of lambs can be used as a predictor of weight and some body biometric measurements. The weight can also be estimated by some biometric measurements.

As injúrias sofridas pelos dígitos dos bovinos são altamente dolorosas e, quando não tratadas, levam a sérios problemas sanitários, afetando diretamente a produtividade e o bem-estar dos animais. A prevalência dessas enfermidades já é bem estabelecida em vacas leiteiras, todavia, no gado de corte em varias regiões do país pouco se sabe sobre sua ocorrência. Deste modo, objetivou-se realizar um estudo sobre a ocorrência de doenças podais em bovinos de corte no estado do Pará. Foram utilizados nesse estudo os cascos de 1318 bovinos (1108 fêmeas e 210 machos) advindos de diversos municípios e mesorregiões do estado do Pará, obtidos em um abatedouro localizado em Belém. Após o abate, cada unha foi individualmente examinada para diagnóstico e eventual classificação das doenças. A análise estatística dos dados foi conduzida com base no teste de Qui-quadrado (x2), com nível de significância de 5%, a fim de quantificar e qualificar as lesões podais. Observou-se que 26,25% (346/1318) dos bovinos avaliados apresentavam pelo menos uma lesão em uma das regiões do casco, sendo que nos bovinos criados em lotação contínua as enfermidades dos dígitos mais prevalentes foram a hiperplasia interdigital, doença da linha branca (fissura e abscesso de linha branca) e erosão de talão. A incidência de lesões podais foi maior em fêmeas.

General Veterinary ,Animal Science and Zoology ,Food Science - Abstract
A criação de búfalos no mundo todo e, em particular no Brasil e países do Mercosul, vem se expandindo. Todavia, para obtenção de índices satisfatórios de produtividade, os animais necessitam de uma boa gestão da sanidade. Dentre as muitas doenças comuns aos bovinos, algumas se comportam diferentemente em bubalinos. Portanto, objetivou-se com esse estudo descrever a prevalência das enfermidades podais em bubalinos criados em áreas de várzea e campos alagados da Ilha de Marajó. O estudo foi realizado em matadouro localizado no município de Belém, utilizando-se 177 bubalinos (97 fêmeas e 80 machos) criados em lotação contínua em fazendas localizadas no arquipélago do Marajó. Os 708 cascos foram examinados individualmente, onde cada uma das 1416 unhas e 708 espaços interdigitais (2124 áreas dos cascos) foram classificados de acordo com a doenca apresentada. A análise estatística dos dados foi conduzida com base no teste de Qui-quadrado (x2), com nível de significância de 5%, a fim de verificar associação significativa entre sexo e cada uma das variáveis estudadas. O estudo mostrou que 14,12% (25/177) dos búfalos avaliados apresentavam pelo menos uma lesão em uma das áreas dos cascos. Das 2124 áreas examinadas, 1,74% (37/2124) apresentavam enfermidades podais. Tanto em machos como em fêmeas, a doença mais prevalente foi a unha em tesoura (UT), com 0,86% (10/1164) e 1,04% (10/960) de unhas afetadas pela doença, respectivamente (p = 0,1571), sendo que 0,38% (4/1062) das unhas com UT foram diagnosticadas nos membros anteriores, enquanto 1,51% (16/1062) nos membros posteriores (p = 0,0414). Considerando-se o plano mediano do corpo dos animais, 0,56% (6/1062) das UT foram observadas nas unhas direitas e 1,32% (14/1062) nas esquerdas (p = 0,0387). Os dados obtidos permitem observar que em bubalinos, tanto para machos quanto para fêmeas, a lesão mais prevalente é a UT, o que possivelmente está relacionado à ausência da prática de casqueamento corretivo.

O experimento foi realizado com o objetivo de investigar a dinâmica da infecção por nematódeos gastrintestinais em vacas no periparto. Utilizaram-se 106 vacas de corte, divididas em dois grupos: o grupo 1 (G1), constituído por 42 vacas de primeira e segunda cria; e o grupo 2, (G2) por 76 vacas de terceira cria ou mais. A partir dos 120 dias do pré-parto até os 90 dias pós-parto, coletaram-se fezes para contagens de ovos por grama de fezes (OPG) e sangue para determinação do volume globular e hemoglobina de cada um dos animais a intervalos mensais. Nos mesmos intervalos, avaliaram-se os escores de condição corporal (ECC). Os valores médios ± desvios-padrão de OPG para os animais do grupo 1 foram iguais a 19,4 ± 42,9, enquanto para os do grupo 2 foram de 31,1 ± 68,0 não havendo diferenças significativas entre eles, tampouco entre os valores hematológicos que permaneceram nos padrões normais para ambos os grupos. Maiores contagens de OPG foram observadas no período pós-parto, com médias de 32,5 ± 55,5 e 51,5 ± 84,8 para os grupos G1 e G2, respectivamente. Observou-se diferença significativa (p < 0,05) nos parâmetros estudados, quando foram comparados os períodos pré e pós-parto dentro de cada um dos grupos, com diminuição dos valores hemáticos e escore corporal e aumento dos valores de OPG no pós-parto. Os resultados sugerem que as vacas podem estar mais susceptíveis à infecção por nematoides desde o parto até os 90 dias pós-parto; todavia, vacas adultas, quando bem manejadas, não constituem fator importante na epidemiologia das verminoses gastrintestinais, mesmo no período pós-parto. The experiment was conducted to investigate the dynamics of infection by gastrointestinal nematodes during the periparturition period in cows. One hundred and six beef cows were divided into two groups: G1 was formed by 42 cows of one and two parturitions, and G2 by 76 cows of three or more parturitions. From the 120 days pre partum until the 90 days post partum, feces were collected for faecal egg counts (EPG) while blood was collected to determine the packed cell volume and hemoglobin levels of each animal, with monthly intervals. In the same intervals the body condition scores (BCS) were evaluated. The mean values ± standard deviation of the EPG for G1 were equal to 19.4 ± 42.9, and for G2 31.1 ± 68.0. No significant differences were observed between G1 and G2 in relation to EPG and hematological parameters, which remained within normal patterns for both groups. The two groups had higher counts of EPG in the post partum period than in the pre partum period, with averages of 32.5 ± 55.5 and 51.5 ± 84.8 for groups G1 and G2, respectively. A significant difference (p < 0.05) in the parameters was observed when comparing the pre and post partum within each group studied resulting in declining values of blood and body score and an increase in EPG in the post partum. The results suggest that the cows may be more susceptible to infection by nematodes from giving birth up to 90 days post partum. However, adult cows, when well-managed, are not an important factor in the epidemiology of gastrointestinal nematodes, even in the post partum period.

General Veterinary - Abstract
Objetivou-se quantificar a ocorrencia de lesoes em carcacas bovinas, mensurar o impacto economico do descarte dessas partes para o produtor e para o frigorifico, assim como correlacionar a distância entre a fazenda e o abatedouro com as informacoes levantadas. A pesquisa foi realizada em um frigorifico sob controle do Servico de Inspecao Estadual – SIE, no municipio de Parauapebas - PA. Foi acompanhado o abate de 490 femeas bovinas oriundas de 25 propriedades. A quantidade de animais examinados foi determinada de acordo com o fluxo de abate do frigorifico (10% de animais/dia). A estatistica descritiva e de inferencia dos dados foi obtida por meio do programa SAS® versao 9.3. Foi possivel observar que a ocorrencia de lesoes na carcaca de animais durante o abate foi alta (99,0%), independentemente se a natureza era traumatica ou abscedativa. A presenca de lesoes nas carcacas culminou em grandes prejuizos economicos, tanto para o produtor (R$ 11,67 / animal) como para o frigorifico (R$ 13,41 / animal). As analises de correlacao entre a distância das fazendas para o abatedouro nao apresentaram significância para nenhuma das variaveis-resposta analisadas nesta pesquisa (P > 0,05). Conclui-se que a ocorrencia de lesoes nas carcacas de bovinos abatidos no Municipio de Parauapebas – PA e alta e tem impacto economico substancial sobre a rentabilidade e venda de cortes carneas, e que a distância entre a fazenda e o abatedouro, isoladamente, nao e determinante para a alta ocorrencia de lesoes nas carcacas de bovinos.

No período periparto ocorrem importantes adequações fisiológicas que, se não forem efetivas predispõem a fêmea a enfermidades metabólicas. O conhecimento desta adaptação é relevante para que sejam implementadas, precocemente, medidas preventivas a poupar perdas produtivas. Com este objetivo foi avaliado o perfil energético e hormonal de ovelhas Santa Inês durante a gestação e puerpério. Foram utilizadas 10 ovelhas não gestantes (G0), 10 gestantes de um (G1) e 14 gestantes de dois e três fetos (G2). Foram avaliadas concentrações plasmáticas de glicose, ácidos graxos não esterificados (AGNE), betahidroxibutirato (BHB), e as concentrações séricas de insulina, glucagon, cortisol, triiodotironina (T3) e tiroxina (T4) a partir do 88º dia de gestação até o 28º dia pós-parto. No terço final de gestação, ovelhas gestantes apresentaram maiores concentrações de AGNE, T3 e T4 que as ovelhas não gestantes. No momento do parto foram observadas maiores concentrações de glicose, AGNE e T3 para todas as ovelhas gestantes em relação às não gestantes. Não houve diferença entre as ovelhas gestantes de um, dois ou três fetos. As diferenças observadas ocorreram apenas entre ovelhas gestantes e as vazias. Portanto, quando há adequada adaptação neste período de elevado desafio metabólico, os parâmetros bioquímicos aqui considerados independem do número de fetos gestados e podem ser considerados como valores de referência para ovelhas gestantes de um feto ou mais fetos do terço médio de gestação ao primeiro mês pós-parto. Important physiological adaptations occur in the periparturient period; their failure predispose the ewe to metabolic diseases. Knowledge of normal changes makes an early recognition and treatment of mal functions possible and enables prevention of diseases and losses. The biochemical profile of Santa Ines ewes from the 88th day of gestation until 28 days after parturition was evaluated and compared to non pregnant controls. The ewes were divided in groups according to the number of fetuses: G0, non pregnant (10); G1, one (10); G2, two and three fetuses (14). All animals had their heart and respiratory rates as well as their ruminal motility recorded. Serum and plasma was analyzed for the following parameters: glucose, non esterified fatty acids (NEFA), beta hydroxibutyrate (BHB), T3, T4, insulin, glucagon and cortisol activities. Results showed changes in biochemical variables of energy and protein profile during pregnancy and parturition. During the last third of gestation, all ewes showed slightly increased NEFA, T3 and T4 levels when compared to non pregnant ewes. At lambing pregnant ewes, had higher glucose, NEFA and T3 levels. No significant differences on measured parameters comparing simple and multiple gestations were observed. Therefore, when there is adequate adaptation in this period of high metabolic challenge, biochemical parameters considered here are independent of the number of fetuses gestate and can be considered as reference values for a pregnant ewes from the middle third of gestation to first month postnatal period.

The purpose of this study was to establish normal reference electrocardiographic (ECG) values for standard limb lead II in Saanen goats. For this, were used 19 healthy adult female Saanen goats. And for reference values for the ECG parameters, were used 95% confidence level. The overall P, Q, R, S and T durations (seconds) were 0.03±0.01, 0.02±0.005, 0.03±0.014, 0.03±0.011, 0.06±0.014 respectively, and the reference values were 0.01-0.04, 0.01-0.02, 0.01-0.06, 0.02-0.04 and 0.04-0.08 respectively. The amplitudes (milivolts) of these waveforms were 0.1±0.031, 0.06±0.023, 0.44±0.312, 0.39±0.434, 0.26±0.164 (T negative) and 0.15±0.071 (T positive), respectively. The reference values were 0.05-0.15, 0.05-0.1, 0.05-1.2, 0.05-1.1 and -0.2-0.7 respectively. The PR and QT interval, the QRS complex and the ST segment durations (seconds) were 0.08±0.018, 0.26±0.03, 0.05±0.008, 0.15±0.041 respectively. The reference values were 0.06-0.12, 0.2-0.32, 0.04-0.07 and 0.11-0.26, respectively. It was possible to observe differences in ECG of Saanen goats regarding the amplitude and duration of the constituents when compared to the results of other breeds. Therefore it is necessary to conduct further studies to allow comparisons, detect and diagnose cardiac arrhythmias and help the development of therapies. O objetivo deste estudo foi de estabelecer os valores de referência para o eletrocardiograma normal de derivação II de cabras Saanen sadias. As durações totais (segundos) das amplitudes de P, Q, R, S e T foram 0.03±0.01, 0.02±0.005, 0.03±0.014, 0.03±0.011, 0.06±0.014, respectivamente, e os valores de referência foram 0.01-0.04, 0.01-0.02, 0.01-0.06, 0.02-0.04 e 0.04-0.08, respectivamente. As amplitudes (milivolts) dessas formas de onda foram 0.1±0.031, 0.06±0.023, 0.44±0.312, 0.39±0.434, 0.26±0.164 (T negativo) e 0.15±0.071 (T positivo), respectivamente. Os valores de referência foram 0.05-0.15, 0.05-0.1, 0.05-1.2, 0.05-1.1 e -0.2-0.7, respectivamente. As durações (segundos) dos intervalos PR e QT, do complexo QRS e do segmento ST foram 0.08±0.018, 0.26±0.03, 0.05±0.008, 0.15±0.041, respectivamente. Os valores de referência foram 0.06-0.12, 0.2-0.32, 0.04-0.07, e 0.11-0.26, respectivamente. Foi possível observar diferenças em relação à duração e amplitude dos constituintes do ECG quando comparados com os resultados de outras raças. Portanto, torna-se necessário a realização de mais estudos para se permitir comparações, detectar e diagnosticar arritmias cardíacas bem como auxiliar no desenvolvimento de terapias.
