Effects of porcine bile acids on growth performance, antioxidant capacity, blood metabolites and nutrient digestibility of weaned pigs

Abstract This experiment was conducted to investigate the effects of porcine bile acids (BA) on growth performance, antioxidant capacity, blood metabolites and nutrient digestibility of weaned pigs. One hundred and eighty pigs were assigned into five groups for 42 days. Pigs were fed a corn-soybean meal basal diet or a basal diet supplemented with 60, 80, 100 or 120 mg/kg BA. Six pigs per treatment were selected for blood sampling at days 28 and 42. Fresh fecal samples were collected from each pen from day 39–42. Supplementation with BA improved average daily gain (linear, P
