The effect of atractylodes polysaccharide on the growth performance,apparent digestibility of nutrients,and antioxidant capacity of nursery pigs
This experiment investigates the effects of Atractylodes macrocephala polysaccharides on the growth performance,nutrient apparent digestibility,and antioxidant capacity of protected pigs.400 binary(Changbai×Dabai)hybrid pigs with an average weight of 8.71±0.15 kg were randomly divided into 4 treatments,with 10 replicates per treatment and 10 pigs per replicate.They were fed with experimental feed supplemented with 0,120,240,and 480 mg/kg Atractylodes macrocephala polysaccharides(AP),respectively.The experiment included a 3-day preparation period and a 32 day main trial period.The results showed that the AP group at 480 mg/kg significantly increased the final weight of piglets by 2.86%,3.38%,and 2.41%(P＜0.05)compared to the other three groups,and the daily weight gain significantly increased by 5.11%,4.84%,and 3.61%(P＜0.05),respectively;Compared with the control group,the feed to meat ratio of the 480 mg/kg AP group significantly decreased by 5.59%(P＜0.05).The digestibility of DM in the AP group of 240 and 480 mg/kg significantly increased(P＜0.05),while the digestibility of CP and energy in the AP group of 480 mg/kg significantly increased(P＜0.05).Serum:The T-AOC and GSH Px activities were significantly increased(P＜0.05)in the AP groups at 240 and 480 mg/kg,while the CAT activity was significantly increased(P＜0.05)and the MDA content was significantly decreased(P＜0.05)in the AP group at 480 mg/kg;Muscle:The T-AOC and CAT activities were significantly increased(P＜0.05)and the MDA content was significantly decreased(P＜0.05)in the AP groups at 240 and 480 mg/kg.Conclusion:Under the conditions of this experiment,480 mg/kg of Atractylodes macrocephala polysaccharide promotes the growth performance of piglets by enhancing their digestion,absorption,and antioxidant capacity.
