Twenty-seven male Saanen kids were used in a completely randomized design to investigate the effect of feed restriction on retail and biological carcass yields, proportion of carcass retail cuts, carcass compactness, leg tissue composition, and ribeye area (REA). Animals were assigned to one of the following treatments: 0 (free access to feed: ad libitum), 30 or 60% of feed restriction. Initial body weight (BW) averaged 5 kg and animals were slaughtered when they reached 20 kg BW. Data were submitted […]

This study was conducted to evaluate the use of ultrasound measurements to predict carcass composition of 115 steers (Nellore, ½ Angus x Nellore, ½ Simental x Nellore, and Canchim) with different frame sizes (small and large) and average initial body weight of 329 kg. After 120 days in a feedlot, animals were weighed followed by ultrasound measurements of rib eye area (RA) and fat thickness (FT). Animals were slaughtered and measurements of carcass RA and FT, weights of hindquarter, forequarter, […]
