Anal fat fold (AFFT) measurement and body composition of calves at 6 months of age according to treatment groupEquations used to calculate the body composition were taken from Johnson (1994). Different alphabetic superscripts denote group mean values that are statistically significantly different from each other, a, b and c for P<0.05

Equations used to calculate the body composition were taken from Johnson (1994).

(1)=72.92 (if males)/69.97(if females)−0.090×AFFT−0.027×ELW; (2)=4.37(if male)/8.32 (if female)+0.132×AFFT+0.038×ELW; (3)=18.81−0.029×AFFT−0.010×ELW.
