The effect of lycopene on growth performance and intestinal antioxidant indicators in piglets
To explore the effects of lycopene on the growth performance and intestinal antioxidant indicators of weaned piglets.600 weaned piglets with an average weight of(6.62±0.12)kg were randomly divided into 4 groups,with 10 replicates in each group and 15 piglets in each replicate.Add 0,200,400,and 800 mg/kg of lycopene to the feed as the experimental feed.The experiment lasted for 73 days,including 10 days of pre testing and 63 days of formal testing.Compared with the control group,the final body weight of weaned piglets fed with 400 mg/kg lycopene significantly increased by 3.8%(P＜0.05),and the average daily weight gain of weaned piglets significantly increased by 4.6%(P＜0.05);The feed to weight ratio of weaned piglets fed with 400 mg/kg lycopene was significantly reduced by 3.8%(P＜0.05);In addition,the addition of lycopene to the diet had no significant effect on the average daily feed intake of weaned piglets(P＞0.05).The addition of 400 and 800 mg/kg lycopene to the diet significantly reduced the content of malondialdehyde in the duodenum of piglets(P＜0.05)and significantly improved T-AOC ability;The addition of lycopene to the diet significantly increased the GSH Px activity in the jejunum of weaned piglets(P＜0.05),and significantly reduced the MDA content in the jejunum;The addition of 400 and 800 mg/kg lycopene significantly increased the GSH Px activity in the ileum of weaned piglets(P＜0.05),while the addition of 800 mg/kg lycopene significantly increased the T-AOC ability in the ileum of weaned piglets(P＜0.05);In addition,the addition of lycopene to the diet had no significant effect on the activities of GSH Px,T-SOD,and CAT in the duodenum of piglets(P＞0.05);There was no significant effect on the activities of T-SOD,CAT,and T-AOC in the jejunum(P＞0.05);There was no significant effect on T-SOD,CAT activity,and MDA content(P＞0.05).In summary,adding lycopene to the diet can promote the growth and development of piglets by enhancing their intestinal antioxidant capacity.Under the conditions of this experiment,the optimal amount of lycopene added is 400 mg/kg.
