Influence of prefast feed intake on recovery from feed and water deprivation by beef steers.
A trial was conducted with 60 steers (257 kg) to determine the influence of prefast feed intake on recovery from feed and water deprivation. For 3 d, steers were fed a 35% roughage diet at 1 (LI) or 1.75% (MI) of body weight or ad libitum (AL). Steers were then deprived of feed and water for 24 h, limit-fed and watered for 24 h, deprived of feed and water for 48 h and then allowed ad libitum fe...
متن کاملSupplemental vitamin D3 concentration and biological type of beef steers. I. Feedlot performance and carcass traits.
Because of the Ca dependency of the calpains, oral supplementation of vitamin D3 (VITD) can increase the Ca content of muscle to activate the calpains and improve tenderness. Feedlot steers (n = 142) were arranged in a 4 x 3 factorial arrangement consisting of four levels of VITD (0, 0.5, 1, and 5 million IU/[steer x d]) for eight consecutive days antemortem using three biological types (Bos in...
متن کاملEffects of dietary copper concentration and source on performance and copper status of growing and finishing steers.
Performance and Cu status were measured in growing and finishing steers supplemented with different copper (Cu) concentrations and sources. Sixty Angus (n = 36) and Angus x Hereford (n = 24) steers were stratified by weight and initial liver Cu concentration within a breed and randomly assigned to treatments. Treatments consisted of 1) control (no supplemental Cu); 2) 20 mg Cu/kg DM from Cu sul...
متن کاملEf®cacy of chromium-yeast supplementation for growing beef steers
This experiment was conducted to determine the ef®cacy of feeding chromium yeast to growing beef steers. Animal growth, gain ef®ciency, and blood glucose kinetics were determined in 24 beef steers (initial body weight253 4 kg) fed a corn silage-based diet supplemented with 0 (control), 100, 200, or 400 mg chromium from high-chromium yeast/kg of diet dry matter. Intravenous glucose tolerance te...
متن کاملInfluence of sire growth potential, time on feed, and growing-finishing strategy on cholesterol and fatty acids of the ground carcass and longissimus muscle of beef steers.
The purpose of this study was to determine how diverse beef cattle production systems affect fatty acids and cholesterol of meat. Crossbred cows were bred by AI to high (H) or moderate (M) growth rate potential bulls to produce spring- or fall-born calves. Steer calves from these matings were placed on finishing diets at three ages. Spring-born steers were started at 6 or 18 mo of age (A6 and A...
