Estimation of economic weights for a beef cattle selection index
… was used to estimate effect of genetic change in mature size (WMA), maximum daily milk production (PMA) and 60-d conception rate (CP) on costs per 100 kg slaughter weight (COST) and costs per 100 kg weaned weight (WNCOST) both adjusted for cull cow sales. Genetic inputs were defined as peak values …
