Abstract
SummaryBlood samples from 180 Guernsey cows and 599 Holstein cows were typed for post‐albumins (Poa). The genotypes were compared for breeding efficiency, mean return interval, anestrus interval, service interval, gestation length and lactation length. Poa SF cows had a significantly shorter (P < 0.01) mean return interval than SS cows. The effect is associated with order of insemination, but is independent of lactation number. None of the other parameters showed genotypic differences.
