Abstract

In this study, unfavorable ROH haplotypes causing reduced performance in fertility traits were identified. Of particular interest are haplotypes affecting both production and fertility traits. Two such haplotypes were identified that had a consistent unfavorable effect across age at calving (for heifers and first parity cows), age at first service, and milk production traits
