End Date: Dec 31, 2012
Bull calves will be castrated or remain intact, and be dewormed and vaccinated. Blood and fecal samples will be collected. Calves will receive either an estradiol, a trenbolone acetate, or no implant. Animals will be transported approximately 40 miles to induce shipping stress. Calves will be pastured and provided feed supplementation for 150 days. Additional samples will be collected and animals will be sent to feedyard. Once the feedyard phase is complete, carcass data will be obtained.
