| The antimicrobial susceptibility of 25 Campylobacter sp strains isolated from calves with and without diarrhea - 7 C. coli, 16 C. fetus and 2 C. jejuni was studied by the disk diffusion method. Eleven antimicrobial agents were tested amikacin, ampicillin, kanamycin, chloramphenicol, erythromycin, gentamicin, neomycin, nitrofurantoin, penicillin G, tetracycline and sulfamethoxazole-trimethoprim. All Campylobacter sp strains were susceptible to amikacin, ampicillin, chloramphenicol, erythromycin, gentamicin, neomycin and nitrofurantoin. Three strains were moderately susceptible to kanamycin (2 C. coli and 1 C. fetus). All the strains were resistant to penicillin G. Two C. fetus strains were moderately susceptible to sulfamethoxazole-trimethoprim and 1 C.... |

| The clinical conditions of healthy calves infected with 10(9) CFU of Salmonella Typhimurium were evaluated and the viability of the experimental model in disease induction was verified. Twelve male Holstein calves, 10 to 15-days old, were examined. They were allocated into two groups, control and experimentally infected. Animals were submitted to clinical examination after inoculation and at every 24 hours, during six days after infection. Samples of rectal swabs were collected for Salmonella Typhimurium isolation. Results showed that all animals had different degrees of diarrhea, with mucus and bleeding, 24 to 72 hours after experimental infection with Salmonella Typhimurium, accompanied by fever, but no signs of sepsis. The isolation of Salmonella... |

| A pecuária de corte é a principal atividade econômica desenvolvida na região do Pantanal. É caracterizada pela forma extensiva de produção e pelo predomínio da fase de cria. De maneira geral, a atividade tem sido desenvolvida com baixa adoção de tecnologias e poucas alterações no ambiente original. A utilização de campos naturais, invernadas grandes e o baixo efetivo bovino por unidade de área são algumas das características que favoreceram a conservação da região. Contudo, o desempenho produtivo abaixo da média do Estado (Zimmer et al., 1998), a premente redução na área das propriedades e a queda na rentabilidade da atividade têm comprometido a eficiência econômica dessa forma de criação. Nos últimos anos, as dificuldades econômicas dos produtores têm... |

| An immunoistochemical (IHC) test was developed to detect bovine respiratory syncytial virus (BRSV) in cell cultures and tissues of experimentally infected mice and calves, using a commercial monoclonal antibody (Mab) against human respiratory syncytial virus (HRSV), as a less expensive alternative, instead of producing specific monoclonal antibodies to BRSV. Clinical samples from calves suffering respiratory disease were also submitted to this test. IHC detected BRSV antigens in mouse tracheas (3, 5 and 7 days post-infection) and lungs (5 and 7 days post-infection), and in one of three lungs from experimentally infected calves. Lungs samples from two naturally infected calves were tested and resulted positive for BRSV by the IHC test. These results suggest... |

| The fluctuations in the plasma levels of several bone markers were investigated in newborn calves. Experiment 1 monitored the postnatal changes in the plasma levels of tartrate-resistant acid phosphatase isoform 5b (TRAP5b), total alkaline phosphatase (t-ALP) and bone-specific alkaline phosphatase (BAP) in four calves. These markers increased significantly from 9−20 hr after the first colostrum-suckling compared with the values immediately after birth. Experiment 2 evaluated changes in the plasma TRAP5b, t-ALP, BAP and type I collagen cross-linked N-telopeptide (NTx) levels within 2 days post-birth in five calves with successful passive immunization via colostrum (non-deficient group) and five others with poor colostrum intake (deficient group). The... |

| ABSTRACT: This study compared the effects of enteral electrolyte solutions with different osmolarities in Holstein cattle. Eighteen newborn calves were evenly divided into three groups and administered the following treatments: hypotonic electrolyte solution (ESHYPO) containing 4g NaCl, 0.5g KCl, 1g sodium acetate, and 7.5g dextrose diluted in 1,000mL water; isotonic electrolyte solution (ESISO) containing 5g NaCl, 1g KCl, 2g sodium acetate, and 10g dextrose diluted in 1,000mL water; and hypertonic electrolyte solution (ESHYPER) containing 6g NaCl, 1g KCl, 3g sodium acetate, and 15g dextrose diluted in 1,000mL water. Solutions were administered at a rate of 15mL kg-1hr-1 for 12 hours in a continuous flow. All three solutions increased the concentration of... |

| Na pecuária de corte, a exploração comercial do sistema de cria se constitui na fase do sistema produtivo, que envolve a criação e o manejo não só das matrizes bovinas e seus respectivos bezerros ate a desmama, mas também das novilhas de reposição e dos touros. Esse sistema tem por objetivo a produção de bezerros desmamados que representa a maior fonte de receita do criador. A venda de vacas descartadas e outros animais, apesar de contribuírem para a produção total, e uma fonte de receita marginal. Portanto, a viabilidade do sistema vai depender da eficácia e eficiência com que são utilizados os meios disponíveis para a otimização da produtividade. O escopo deste trabalho foi o de apresentar e discutir as principais praticas de manejo reprodutivo, que... |

| Foi realizado um levantamento de algumas doenças de bezerros de corte do nascimento ao desmame criados extensivamente na região de Campo Grande, Estado de Mato Grosso do Sul. Foi observado índice médio de mortalidade de 5,9% e o de morbidade de 26,8%. Os maiores índices de mortalidade ocorreram em fazendas com vacas positivas ao teste sorológico para o diagnóstico da brucelose. |

| A healthy 71-day-old female Japanese Black calf was evaluated for fracture of the left humerus. The left humeral fracture was treated by closed repair and unilateral external skeletal fixation (ESF) with an epoxy putty fixator. The calf was active, and eight days after surgery slipped and fell, resulting in breakage of the ESF. The calf underwent repair by transfixation pinning and casting (TPC), which is an alternative to the ESF method. The TPC was removed 37 days after the first surgery, and the calf could bear weight on the left forelimb while walking. This case suggests that recovery after closed repair with TPC for a humeral fracture in an active calf can be successfully managed on the farm. |

| Rectal temperature, heart and respiratory rates, and the course of some blood parameters were monitored in calves during perinatal and neonatal periods. The study was carried out on eight Limousine calves. From all subjects, rectal temperature, heart rate, and respiratory rate were measured. Blood samples were taken at the same hour (9am) from the external jugular vein, and then centrifuged and stored until analyses. By means of an UV spectrophotometer, the following blood parameters were assessed for each subject: total protein, total cholesterol, triglycerides, glucose, non-esterified fatty acids (NEFA), urea, creatinine, cholinesterase, lactate dehydrogenase (LDH), hydroxybutirate, glutamate pyruvate transaminases (GPT), glutamate oxalacetate... |
