Description
Abstract:Weights of slaughter and carcass components were obtained in a serial slaughter of 197 bulls produced in a five breed diallel involving Angus, Brahman, Hereford, Holstein and Jersey. These data were analyzed to characterize body components and the developmental patterns of body components. The bulls were assigned to individual feeding pens at six months of age and provided a 71% TDN ration ad libitum until time of slaughter. Data recorded monthly for all bulls until time of slaughter were weight, height over hooks and monthly feed consumption. Bulls representing each breedtype were randomly assigned to seven slaughter groups: 6, 9, 12, `5, `8, 24, and 30 months. The bulls were deprived of feed and water for an 18-24 hour period preceding slaughter. On the day of slaughter, liveweight, weights of body components normally associated with kill floor loss and warm carcass weight were recorded. Twenty-four hours postmortem linear carcass measurements, quality indicators and chilled carcass weights were recorded. Forty-eight hours postmortem, one carcass side from each bull was partitioned into whole-sale and retail cuts with weights recorded for each cut. Intermuscular and subcutaneous fat was trimmed (to within .25 inch of muscle) from each cut with the fat trim weight of each cut being recorded. Each cut was fabricated into closely trimmed lean and bone trim with the weight for these components recorded for each cut.
