Data are presented as means; SEM, standard error of the mean; m, male offspring; f, female offspring; C, control group; HMB, β-hydroxy-β-methylbutyrate at a daily dose of 0.02 g/kg of body weight; AKG, alpha-ketoglutaric acid at a daily dose of 0.4 g/kg of body weight; n = 12 in each group; different superscript or subscript letters in rows relating to either the primiparous or multiparous dams refers to a significant difference between males in the various treatment groups or females in the various treatment groups, respectively; (p < 0.05).
