Performance, residual feed intake, digestibility, carcass traits, and profitability of Angus-Hereford steers housed in individual or group pens.
Even though the concept of residual feed intake (RFI) is well accepted, several questions remain regarding other traits that may be associated with selection for decreased RFI. These include DM digestibility, carcass composition, profitability, and performance. The objective of this study was to investigate the difference in those traits between low- and high-RFI cattle. Sixty Angus x Hereford ...

متن کاملResidual Feed Intake: Animal Performance, Carcass Quality and Body Composition
Feed efficiency has a major influence on the unit cost of beef cattle production. Gibb and McAllister (1999) have reported that a 5% improvement in feed efficiency has an economic impact four times greater than a 5% improvement in average daily gain. In addition, the cost of feed is second only to fixed costs in importance to the profitability of commercial beef operations (Basarab, 1999). The ...
متن کاملComparison of Feedlot Performance and Carcass Traits of Charolais and Brahman Sired Three-Breed Cross Calves
Feedlot performance and carcass traits were compared between Charolais and Brahman sired three-breed cross calves. Data were obtained on 251 calves (127 heifers and 124 steers). All calves were placed on a self-fed finishing ration immediately after wea,ning and slaughtered when each animal attained an estimated low choice carcass grade. Feedlot performance favored calves sired by Charolais. Ch...
