6 – Calving Ease Direct

calving-ease-direct
Calving Ease Direct EBVs are estimates of genetic differences in the ability of a sire’s calves to be born unassisted from 2 year old heifers.

Calving Ease Direct EBVs are calculated from calving difficulty scores, birth weights, gestation length records and/or genomic information, and are expressed as differences in the percentage of calves that will be born unassisted.

Higher Calving Ease Direct EBVs indicate an animal is expected to produce fewer calving difficulties in 2 year old heifers (i.e. greater calving ease).
