^aSEM = Pooled standard error for means.

^bDay of year.

^cCow BW and BCS change are differences from the start of treatment to the end of treatment.

^dCalf sex ratio = ratio of male to female calves, 1 = male and 0 = female.

^eDystocia Score: 0 = No assistance to 5 = Caesarean section.

^fX² = 1.3, d.f. = 1. Table legend text.
