Effects of low-protein diet supplemented with arginine on the growth performance,blood antioxidant and immune indicators of weaned piglets
This study was conducted to investigate the effects of high reducing dietary crude protein level and supplement with argi-nine on the growth performance,blood antioxidant and immune indicators of weaned piglets.One hundred and twenty eight crossbred piglets(Duroc×Landrace×Large White)were selected and randomly divided into four treatments,each treatment had 4 replicates and each replicate had 8 piglets.The control group was fed a basal diet(CP is 15.98%);The experimental group 1,2 and 3 were supple-mented with 0.4%,0.8%and 1.2%arginine in the basal diet,respectively.The experiment lasted for 16 days.The results showed as follows:Compared with control group,1)The average daily weight gain(ADG)in experimental group 1 and 2 was extremely significant-ly increased(P<0.05),the feed to gain(F/G)in experimental group 2 was significantly lower(P<0.05),the diarrhea rate in experimental group 1,2 and 3 was significantly decreased(P<0.05).2)The blood T-AOC concentrations in experimental group 1 and 2 were signifi-cantly increased(P<0.05),the GSH-PX activity in experimental group 1,2 and 3 were significantly increased(P<0.05),the blood MDA concentrations in experimental group 1 and 2 were significantly decreased(P<0.05).3)The concentrations of IgA and IgG in experi-mental group 1,2 and 3 were significantly increased(P<0.05).In conclusion,the diet of high reducing dietary crude protein level and supplemented with moderate amount of arginine(0.8%)in weaning piglets could improve the ADG,decrease the feed to gain ratio,re-duce diarrhea,and improve antioxidant capacity and immune function.
