Commercial Replacement Heifer Selection
Alison Van Eenennaam, Darrh Bullock, Univ of Kentucky
Typically only a subset of heifers are replacement candidates due to size (smaller heifers are often the ones that are born late(r) in the calving season and are too immature to be cycling in time for the first potential breeding season), other selection criteria (e.g. feet and legs, disposition), and the replacement rate (i.e. what proportion of replacement heifers are selected to return to the herd each year).
