The effect of short#x2010;term grain feeding on liveweight gain and beef quality

摘要

Two serial slaughter experiments were conducted to compare the liveweight gain and carcass quality of 3#x2010;year#x2010;old Angus steers finished on concentrate#x2010;based rations with steers finished on high quality spring pasture in New Zealand. Experiment 1 used a feedlot ration of 70 maize grain and 30 pasture silage and Experiment 2 used barley instead of maize. In both experiments, steers were adjusted to the concentrate ration prior to being fedad libitumfor 12 weeks.
