چکیده انگلیسی
The experiment was conducted to determine the effects of alfalfa saponin extract (ASE) on growth performance and some antioxidant indices in weaned piglets. A total of 96 piglets (Duroc×Landrace×Large white) with 7.5±0.9 kg mean body weight weaned at 28 d of age were randomly assigned to 4 treatments (4 replicate pen per treatment with 3 gilts and 3 castrated males per pen). Diets containing 0, 5, 10, and 15 g ASE/kg were fed to piglets for 30 d. There was a linear improvement in finial body weight, average daily gain, and average daily feed intake (P=0.029, 0.003, and 0.042, respectively) as the level of ASE in pig diets increased. Glutathione peroxidase activity in serum, liver, and muscle of weaned pigs increased linearly (P=0.004, 0.047, and 0.053, respectively) as the level of ASE in pig diets increased. Superoxide dismutase activity in serum, liver, spleen, and muscle increased linearly (P=0.009, 0.006, 0.010, and 0.016, respectively). Serum catalase (CAT) activity increased quadratically (P=0.038), while kidney and muscle CAT activity increased linearly (P=0.051 and 0.052, respectively). Malondialdehyde (MDA) content in serum, liver, spleen, and muscle decreased linearly (P=0.032, 0.011, 0.008, and 0.007, respectively) as the level of ASE in pig diets increased. These findings indicated that dietary inclusion of ASE up to 15 g/kg could increase activity of some antioxidant enzymes in weaned piglets, as well as promote their growth.
