Exogenous porcine somatotropin administered to late pregnant gilts alters liver and muscle functionalities in pig fetuses

Neonatal maturity depends on the maternal capacity to provide nutrients for fetal growth. Pregnant gilts received either daily injections of sterile water (CTL group, n = 15) or of 5 mg of porcine somatotropin (pST group, n = 17) from days 90 to 109 of gestation. At day 110 post-conceptus, pairs of fetuses (one of small and one of average size within a litter) were selected. The dataset shows plasma circulating concentrations of nutrients and gene expression levels in liver and Longissimus muscle in fetuses.
