The effects of dietary daidzein during late gestation on maternal performance, neonatal body composition, carcass and meat quality at market weight, and skeletal muscle cellularity were studied. Multiparous sows received a soybean-free diet (n = 8, control) or the same diet supplemented with 1 mg daidzein/kg body weight (n = 7) daily from d 85 of gestation to parturition. Litter size, litter weight, and birth weight remained unaffected by daidzein feeding. In newborn piglets from litters >15, the proportions of muscle tissue and skin tended to be decreased (P = 0.09) or increased (P = 0.03), respectively, after gestational daidzein feeding. The body fat percentage was higher in response to maternal daidzein (P = 0.04). Postnatal growth and carcass composition at 180 d of age were not affected, however, maternal daidzein supplementation led to increases in longissimus muscle pH45 (P = 0.02) and pHend (P = 0.11) in pigs from large litters. The proportion of fast-twitch glycolytic fibres in semitendinosus muscle was increased (P = 0.06) by maternal daidzein feeding. The results suggest that supplemental daidzein in the maternal diet during late gestation marginally affects meat quality and skeletal muscle cellularity of the progeny.
