| This study evaluated the ingestive behavior of Hostein calves kept in two husbandry systems: feedlot or pasture. We examined the ingestive behavior of 11 male non-castrated calves, with average initial age of 75 days, six of which were individually penned, consuming corn silage and concentrate-based diet at a ratio of 40:60 (on a DM basis), and the remainder, on pearl millet pasture (Pennisetum americanum) receiving concentrate supplementation at 1.0% body weight. Evaluations were held from November to February, from 8:00 am to 6:00 pm. Feedlot calves stay longer (p < 0.05) in idle, both in lying and standing positions, while animals on pasture spent more time in eating and ruminating activities. Confined animals performed a higher number of daily... |

| ABSTRACT: Efficient handling programs that provide high quality colostrum in adequate amounts to dairy farm calves are needed to assure their health and survival. Replacers (or milk substitutes) often become necessary when colostrum presents inadequate quality, or in order to break the cycle of infectious disease transmission. In this study we aimed to assess the effect of anaerobic fermentation processing (colostrum silage) on bacterial that represent interest to animal health. Colostrum samples were inoculated with cultures of Brucella abortus , Escherichia coli , Leptospira interrogans serovar Copenhageni , Mycobacterium bovis , Salmonella Enteritidis , Salmonella Typhimurium , Staphylococcus aureus , and Bacillus cereus and then subjected to... |

| Abstract: The aims of this study were to investigate whether treatments with zinc edetate (Zn) and diphenyl diselenide ((PhSe)2) enhance performance, immune responses, protein metabolism, and oxidant/antioxidant status in calf serum and muscle. Animals were divided into four groups (n=6 each): control (without supplementation), and groups supplemented on days 50 and 70 of life with (PhSe)2, Zn, and a combination of (PhSe)2 and Zn. Animals treated with (PhSe)2 gained more weight by experimental day 220 than did the control group, but there was no difference by the end of the experiment (day 300). The absolute number of leukocytes and lymphocytes increased in groups Zn and (PhSe)2+Zn on day 20 of experiment, but decreased on day 40 in groups (PhSe)2, and... |

| A pecuária no Estado do Acre desenvolve-se sob condições de um clima quente e úmido, fatores estes favoráveis ao desenvolvimento dos ciclos evolutiyos de parasitos diversos. As infecções parasitárias, dentre elas as causadas por helmintos gastrintestinais, têm se constituído em sério entrave ao aumento da produtividade e ao sucesso econômico na exploração bovina, mesmo naquela executada sob adequada tecnologia zootécnica. Com vista ao problema, a Unidade de Execução e Pesquisa de Âmbito Estadual de Rio Branco - UEPAE/Rio Branco-AC, desenvolveu um estudo preliminar para conhecimento da fauna helmintológica em bezerros de corte, visando determinar a. prevalência das espécies que parasitam os bovinos da região, o que, por certo, contribuirá para futuras... |

| ABSTRACT: This study was conducted at a beef cattle breeding farm in the far southern region of Brazil. The birth of a calf with unilateral corneal opacity was immediately reported to the Laboratory of Parasitology, in the Universidade Federal de Pelotas, Rio Grande do Sul, Brazil; blood was collected from the cow and calf before colostrum intake. The umbilical cords from this calf and from six other healthy animals were collected. Serological examination, utilizing an indirect fluorescent antibody test, was done using a cut-off point of 1:100. Polymerase chain reaction (PCR) was also performed using the umbilical cord samples. Serological tests showed that the calf was positive for Neospora caninum at birth, with a titer of 1:1600; a titer of 1:3200 was... |

| Abstract: The aim of this study was to evaluate whether the use phytogenic as feed additive of Holstein calves could exert beneficial effects on animal health and performance. Thirty newborn calves were randomly divided into two groups (control and treated), and the treated consisted of 10 g of the phytogenic product diluted in milk once a day for 30 days. Blood and fecal samples were collected, and fecal score was performed daily in order to determine the occurrence of diarrhea. Treated calves showed higher hematocrit on days 45 and 60 of life. Serum levels of urea, total proteins, globulins and glucose were lower in the treated group on day 60 of life, while triglycerides were lower on days 15 and 60 of life. Serum glutathione S-transferase activity was... |

| O sistema de produção de gado de corte, desde a preparação para a estação de monta ate a terminação dos animais, necessita de um planejamento sanitário. Esse controle, em uma primeira analise, visa a dar maior segurança econômica ao produtor, pela diminuição dos riscos de perdas na produtividade do sistema. Ao mesmo tempo, o sistema vai oferecer um produto mais seguro, do ponto de vista sanitário, para o consumidor. Portanto, a viabilidade da resposta dos investimentos no sistema de produção, com relação ao melhoramento genético e nutrição animal, vai depender da eficácia da prevenção de doenças no sistema. Este trabalho tem o objetivo de discutir a importância do planejamento sanitário nas doenças consideradas importantes, sem a pretensão de esgotar o... |
