Abstract excerpt
This study aimed to identify loci (p < 1 × 10-5) and gene sets (normalized enrichment score (NES) ≥ 3.0) associated with the number of times a heifer is bred to attain a successful pregnancy (TBRD) for Holstein heifers bred by artificial insemination (AI, n = 2754) or that were embryo transfer (ET, n = 1566) recipients. Eight loci were associated (p < 1 × 10-5) with TBRD in AI bred heifers and four loci were...
