Obstructive urolithiasis in Nelore cattle in the Recôncavo of Bahia / Urolitíase obstrutiva em touro Nelore no Recôncavo da Bahia

Background: Urolithiasis is a metabolic disease of ruminants castrated and uncastrated. The formation of uroliths causes trauma and obstruction in the tract urinary. The nutrition and management are the main predisposing factors for this disease. Many cases occur sporadically, but outbreaks can occur or become an endemic problem. This paper describes a case of obstructive urolithiasis in Nelore cattle uncastrated in Recôncavo of Bahia, Brazil. Case: An 4-year-old Nelore cattle, uncastrated male was sent to the Centro de Desenvolvimento da Pecuária da Universidade Federal da Bahia (CPD-UFBA), Bahia, Brazil. by presenting a swelling on the ventral abdomen 5 days ago. Clinical examination revealed the exposure with mucosal necrosis and hemorrhage preputial, and continuous dripping of urine. The animal was euthanized in extremis and submitted to necropsy. The animal was necropsied and samples collected from the abdominal cavity, thoracic cavity, and nervous system. The samples were fixed in 10% formalin, cleaved, processed routinely for histology, embedded in paraffi n, cut at five microns thick and stained with hematoxylin and eosin (HE). Urinary stones collected during necropsy were sent for analysis of chemical composition. The macroscopic had swelling in the ventral abdominal region. By cutting this region was the formation of cavities and fi lled with red liquid and odor uremi

Malignant edema caused by Clostridium chauvoei in a Horse / Edema maligno em equino causado por Clostridium chauvoei

Background: Malignant edema occurs when a wound is contaminated by one or a combination of the following bacteria: Clostridium septicum, C. sordellii, C. chauvoei, C. novyi type A, and C. perfringens type A. Although malignant edema has been recognized as a disease of economic importance in domestic ruminants, it has rarely been reported in horses in Brazil. Immunohistochemistry is a method that combines histological, immunological and biochemical techniques which, with the use of specifi c antibodies, detects the agent in situ. This paper reports a case of malignant edema by Clostridium chauvoei in a horse in Bahia, Brazil.Case: A 4.5-year-old male horse was submitted for necropsy. The clinical history was obtained from the owner. Samples from the abdominal cavity, thoracic cavity, central nervous system and integumentary system were collected. The samples were fi xed in 10% formalin, processed routinely for histology, embedded in paraffi n, sectioned at fi ve microns, and stained with hematoxylin and eosin. Additionally, histological sections were subjected to immunohistochemistry anti-Clostridium perfringens type A, C. septicum, C. chauvoei, C. novyi type A, and C. sordellii. Positive and negative controls were included. The animal presented diffi culty in walking, swelling of the pelvic limbs two days after intramuscular anti-infl ammatory treatment, and died seven hours af

COMPORTAMENTO INGESTIVO DE CORDEIROS SANTA INÊS EM PASTAGEM DE Panicum maximum CV. Aruana: ASPECTOS METODOLÓGICOS

Este estudo teve como objetivo definir o intervalo de tempo do comportamento ingestivo de cordeiros da raça Santa Inês em sistema de pastejo contínuo de capim Aruana (Panicum maximum). Foram utilizados oito animais para registro das atividades de alimentação, ruminação e outras atividades no período de 24 horas. Para tanto, foi calculado os números de períodos de alimentação, ruminação e outras atividades e os tempos despendidos por período de cada atividade. Foram comparados os intervalos de observações de cinco, 10, 15, 20 e 30 minutos. Os tempos despendidos em alimentação, ruminação e outras atividades diferiram nos intervalos estudados. Os valores obtidos das durações médias diárias, para as variáveis: alimentação, ruminação e outras atividades e para as porcentagens de ruminação deitado e ócio deitado não diferiram entre os intervalos de cinco, 10; 15; 20 e 30 minutos. Ao avaliar o número de períodos de alimentação, ruminação e outras atividades, os valores obtidos diferiram entre os intervalos de observações, indicando que à medida que aumentou os intervalos de observações o número de períodos diminuiu. Conclui-se que o intervalo de tempo influencia os resultados do comportamento ingestivo de ovinos machos não castrados da raça Santa Inês. Palavras-Chave: alimentação; metodologia; ovelhas; ruminação.

COMPORTAMENTO INGESTIVO DE DIFERENTES CATEGORIAS DE OVINOS SANTA INÊS EM PASTEJO CONTÍNUO EM Brachiaria decumbens

O objetivo deste trabalho foi avaliar o comportamento ingestivo de ovinos da raça Santa Inês em pastagem de Brachiaria decumbens. O delineamento experimental foi o inteiramente casualizado, com duas categorias (borregas e ovelhas) representando os tratamentos com oito repetições cada. Os animais foram submetidos à avaliação visual do comportamento ingestivo a cada cinco minutos. As variáveis analisadas foram: alimentação, ruminação e ócio, a partir dessas informações foram calculados os períodos de alimentação, ruminação e ócio e os tempos por alimentação, ruminação e ócio. Os resultados evidenciaram que não houve diferença no comportamento ingestivo pelas diferentes categorias de ovinos sob mesma condição de pastejo, com tempos médios de 576,57; 432,51 e 430,94 minutos/dia-1, respectivamente para alimentação, ruminação e ócio. Assim, o comportamento ingestivo não é influenciado pela categoria animal. Palavras-Chave: borregas; ingestão; ócio; ovelhas; ruminação.
