a prop-EG The number of days that exceeded the threshold temperature humidity index in the period, mTHI-EG Minimum temperature-humidity index for each day of the period
b AFC Age at first calving, IFL Interval from the first to last service, CR Conception rate of first service
c S1 control critical period, S2 periods selected based on the Akaike’s information criterion
d Periods were counted based on the first service day; minus means before and plus means after
