Resumo
Avaliaram-se as características de carcaça de búfalos Murrah castrados terminados em confinamento. Foram utilizados 20 bubalinos Murrah (15 meses de idade e peso inicial de 207 kg), castrados e descornados, divididos em quatro grupos homogêneos e abatidos aos 75, 100, 125, 150 dias de confinamento, após período de adaptação. Ao abate, as carcaças foram identificadas, resfriadas por 24 horas para pesagem e cálculo dos rendimentos das meias-carcaças, dos cortes dianteiro, ponta-de-agulha, traseiro total e serrote. Não houve diferença estatística para o rendimento de carcaça. Os pesos de traseiro total, serrote e dianteiro apresentaram aumento linear, porém, observou-se efeito cúbico do período de confinamento sobre os rendimentos de traseiro total e dianteiro. Verificou-se ainda aumento linear dos pesos de filé-mignon, contrafilé, fraldinha, coxão mole, coxão duro, lagarto, sebo, porção comestível e ossos. O período de confinamento promoveu efeito linear decrescente sobre os rendimentos de patinho, músculo traseiro e maminha + alcatra e linear crescente para fraldinha e sebo.
The objective of this trial was to evaluate the carcass traits of feedlot castrated Murrah buffaloes. Twenty castrated hornless Murrah buffaloes averaging 15 months of age and initial body weight of 207 kg were used. Animals were divided in four groups and slaughtered at 75, 100, 125 or 150 days of feedlot after an adaptation period. At slaughter, carcasses were identified, cooled for 24 hours, and weighed for calculation of yields of half carcass, hindquarter, spare ribs, forequarter, and sawcut. There was no significant difference for carcass yield comparing the different periods of feedlot. Weights of sawcut, forequarter, hindquarter, tenderloin, strip loin, thin skirt, topside, outside flat, eye round, tallow, retail beef cuts, and bones all increased linearly while significant cubic effects were observed for yields of forequarter and hindquarter by increasing the days in feedlot. However, yields of knuckle, shank, and beef loin + tri-tip decreased linearly while those of thin skirt and tallow increased linearly when the feedlot period went from 75 to 150 days.
