The proportion of heifers estrual by the first timepoint was greater (P less then 0.0001) with Approach 72 (76 %; 302/395) compared to Approach 66 (61 %; 242/399). The proportion of heifers pregnant as a result of AI differed (P = 0.0005) by semen type (59 % [240/404] for conventional compared with 48 % [187/390] for ****-sorted) but was not affected by approach or approach × semen type.
