Abstract
Twenty-eight cull dairy cows of similar physiological age were fed an alfalfa silage, high-moisture corn ration to appetite once daily for 70 days. At the start of the trial, 14 cows were implanted with a growth promotant (Synovex H). All animals maintained a high rate of gain during the feeding period (1.19 kg/day), but there were no differences between implanted and nonimplanted cows both for feedlot performance and carcass characteristics. Key words: Cull cows, implant, growthThis publication has 4 references indexed in Scilit:
