  1. Bulls 1–5 are designated as the high fertility (HF) group and bulls 6–10 are designated as the low fertility (LF) group. All bulls were individually represented with their in vivo fertility scores and the number of breeding’s. Fertility scores are expressed as the percent deviation of each conception rate from the average conception rate of all the bulls as previously described [26]
