Mature Cow Weight EBVs are estimates of genetic differences between animals in live weight of cows at 5 years of age.
Mature Cow Weight EBVs are calculated from the live weights of cows when their calves are 200 days of age (i.e. at or around weaning), and/or genomic information, and are expressed in kilogram units.
Higher Mature Cow Weight EBVs indicate the animal is expected to produce daughters with heavier mature weights. Heavier mature weights are associated with higher feed and maintenance costs, but conversely higher returns for cull cows.
