^{^a}

Data are least‐squares means ± SEM and, in parentheses, the fraction and percent of cows.

^{^b}

Data are least‐squares means ± SEM. One animal in the choline group with premature calving (277 days) was removed from the data set before analysis. There was no effect of sex or sex × treatment.
