Summary and Implications
This study evaluated 96 Angus-sired heifers that were managed to a regular feedlot endpoint (approx. 0.45 in. fat cover) for harvest or a nonregular (longer) time on feed (approx. 0.70 in. fat cover). Heifers were scanned either 3 or 4 times from approximately 10 months of age through just prior to harvest. This study indicates that when heifers are fed for a longer period, they are able to bring more revenue from increases in quality and hot carcass weight. However, value/cwt was higher for the regular fed heifers when compared to long fed heifers. This is primarily because of the increase in discounts from higher yield grades on long-fed heifers.
