Other common factors affecting fertility are issues with physical health such as lameness and BCS. Reduced BCS is associated with reduced conception rates at first AI postpartum, more days open, and postponed resumption of cyclicity resulting in a longer interval from parturition to first estrus and first service (Roche et al., 2009). Carryover effects of reduced BCS during the transition period have been demonstrated to be detrimental even after the voluntary waiting period, where the likelihood of pregnancy has been found to be reduced with each 0.5-unit decrease of BCS (Buckley et al., 2003; Roche et al., 2007). Lameness also is associated with less pregnancy per AI (Burnett et al., 2017), and increased number of inseminations per conception (Hernandez et al., 2001; Melendez et al., 2003), days to conception (Burnett et al., 2017), and prevalence of ovarian cysts (Melendez et al., 2003). It is not well understood how expression of estrus, BCS, and lame-ness affect fertility. One potential cause may be from disruptions of the events that lead to ovulation. In the present study, we aimed to determine if the reductions in fertility that are found with lesser estrous expression, as well as with lameness and BCS, are associated with the interval from activity alert to ovulation using AAM.
