RESUMO -Objetivou-se avaliar o desempenho de cabritos de três grupos raciais. Foram considerados nas avaliações o peso, o ganho de peso, as medidas biométricas, a conversão alimentar e o custo de produção relativo à alimentação. Utilizaram-se 41 cabritos, machos e fêmeas, de três grupos raciais (A -Alpino; ½ BA -½ Boer + ½ Alpino; e ¾ BA -¾ Boer + ¼ Alpino), avaliados aos 60, 90 e 120 dias em sistema de confinamento. As médias foram comparadas por análise de variância utilizando-se o teste Tukey. O desempenho não diferiu entre os grupos raciais. O escore corporal foi maior nos animais ¾ BA, o que pode representar vantagem econômica ao produtor se esses animais forem comercializados vivos. Com o avanço da idade, houve aumento do comprimento corporal, da altura anterior, da altura posterior, do perímetro torácico, do perímetro da perna, da largura da garupa e da largura do peito. Os machos foram superiores às fêmeas quanto às medidas biométricas e quanto ao peso ao nascimento, aos 60 e aos 90 dias. Os machos Alpinos foram mais pesados aos 120 dias e apresentaram, ainda, maior ganho de peso no intervalo dos 30 aos 60 dias. O menor custo de produção relativo à alimentação por quilograma de cabrito produzido foi observado aos 90 dias de idade.

Therefore, 41 kids in a feedlot system were used in this study. Data were submitted to analysis of variance using the Tukey test for comparison of means. No difference in performance was observed among the three different groups of animals (Alpine, ½ BA, and ¾ BA). Body condition score was greatest in ¾ BA kids, which may represent additional profit to producers if animals are sold alive. As expected, most body measurements increased with age. Body measurements and weight at birth, 60 and 90 days of age were all greater on males than females. In addition, Alpine males were heavier than females at 120 days of age. They also gained more weight from 30 to 60 days when compared to females.The lowest production cost (kg of feed per kg of weight gain) was observed at 90 days of age.

RESUMO -Este trabalho foi realizado com os objetivos de quantificar e qualificar a carcaça e os cortes cárneos de cabritos de dois sexos (machos e fêmeas) e três grupos raciais -Alpino; ½ Boer + ½ Alpino (½ BA); e ¾ Boer + ¼ Alpino (¾ BA) -abatidos em três idades (aos 60, 90 e 120 dias de confinamento), visando avaliar o aproveitamento de cabritos provenientes de rebanhos leiteiros. As carcaças foram avaliadas pelas características de peso, rendimento, conformação, gordura de cobertura, comprimento interno e externo, comprimento da perna, perímetro da garupa, profundidade torácica, largura da garupa, compacidade, rendimento dos cortes cárneos e proporção dos tecidos. Os dados foram analisados em delineamento inteiramente casualizado, em esquema fatorial incompleto 2 × 3 × 3 (2 sexos × 3 grupos raciais × 3 idades de abate). O aumento da idade dos animais promove aumento do peso e das medidas da carcaça, assim como dos componentes comestíveis da carcaça e do rendimento comercial. Mestiços Boer apresentam maior compacidade de perna e menos osso em relação aos Alpinos. O grupo racial, a idade de abate e o sexo não influenciam a maciez da carne.Palavras-chave: compacidade, gordura, músculo, rendimento comercial Carcass and meat tenderness of goats according to age, breed group and age at slaughterABSTRACT -The objective of this experiment was to evaluate the yield and quality of the carcass and meat cuts from kids of both sexes, slaughtered at three different ages, aiming to use animals from dairy herds. Forty-one kids were used, from three breed groups: Alpine, ½ Boer ½ Alpine (½ BA) and ¾ Boer ¼ Alpine (¾ BA), which were slaughtered at 60, 90 or 120 days of slaughter age. The animals were raised in a feedlot system. The following carcass traits were evaluated: carcass weight, commercial yield, conformation, subcutaneous fat, internal and external length, leg length, rump perimeter, thoracic depth, rump width, compactness, meat cut yield and tissue proportion. Meat tenderness was evaluated by means of the Warner-Bratzler shear force. Data were analyzed as an incomplete factorial arrangement (2 sexes × 3 breed groups × 3 slaughter ages), in a complete randomized design. As age increased, so did carcass weight and characteristics, as well as the weight of edible carcass components and commercial yield. The Boer crossbreds showed higher leg compactness and less bone compared to the Alpines. No difference in meat tenderness was observed for breed group, age or sex.

Radical hysterectomy is indicated as a last resource in pyometra that does not respond to pharmacological therapy, uterine torsion with vascular involvement and onset of necrosis, neoplasia, ruptures of impossible synthesis and rarely, segmental aplasia with accumulation of secretion. The incidence of pyometra is multifactorial, being an unusual condition in this species. Generally, it is originated by failure of the physiological draining of the uterine fluid, which may be due to the presence of cervical adherences or to a sinuous or irregular cervical canal, as well as due to its stenosis. The diagnosis is conducted by a complete gynecological exam, which consists of rectal palpation, ultrasound examination, culture and antibiogram of the content, and can be complemented by uterine biopsy when it is possible. Differential diagnosis should be conducted to confirm the absence of gestation, mucometra and pneumometra. The present report is about an equine female, Mangalarga breed, 23 years old, body weight of 470 kg, diagnosed with recurrent chronic pyometra that was unsolved by conventional methods, and surgical intervention was performed for hysterectomy as a treatment of selected.

-The objective of this experiment was to evaluate levels of replacement (0, 33, 67 and 100%) of corn silage with fresh sugarcane in dairy-goat diets on the ingestive behavior of these animals. Eight lactating Alpine goats (after lactation peak) with a live weight of 51.95±3.29 kg were distributed into two 4 × 4 Latin squares according to their milk production. Animals were placed in individual pens where they received diets ad libitum, twice a day, with a roughage:concentrate ratio of 40:60, during 72 days of experiment. The evaluated variables were time spent feeding (TSF), ruminating (TSR), idle (TSI) and chewing (TSC), dry matter intake (DMI), neutral detergent fiber intake (NDFI), feeding efficiency of dry matter (FE DM ) and neutral detergent fiber (FE NDF ), rumination efficiency of dry matter (RE DM ) and neutral detergent fiber (RE NDF ), number of ruminal boli per day (NRB) and number of rumination chews per day (NRC). The different treatments had no effect on TSF or TSR. However, a linear effect was observed on TSC. There was a linear effect on TSI, in which the highest value was observed in the treatment with 0% of sugarcane inclusion. A quadratic effect was observed on dry matter intake, with minimum point of 2.14 kg/day for 68.04% of sugarcane inclusion; however, NDFI was not affected by the different treatments. There was no effect of treatments on FE DM , although a quadratic effect was observed on FE NDF , wherein the lowest value was observed in the treatment with 67% of sugarcane inclusion. There was no effect of different levels of corn silage replacement on RE DM , RE NDF , NRB or NRC. Sugarcane can be replaced with corn silage without changing the times spending on feeding and rumination.
