Effect of Estrus Activity when Evaluating Feed Efficiency in Heifers
Abstract
Estrus activity in virgin heifers tends to affect the outcome in measurements observed during performance and feed utilization tests. Prior to any testing it is prudent to identify those females that have shown estrus activity consistently and those which have not, then evaluate animals for feed efficiency grouped by stage of sexual maturity.
