高糖补饲对围产期牦牛生长性能、血清生化及抗氧化指标的影响
Effects of high sugar supplementation on growth performance,serum biochemical,and antioxidant indexes of perinatal yaks
摘要
Abstract
The experiment aimed to investigate the effects of high sugar supplementation on the growth performance,serum biochemical,and antioxidant indexes of perinatal yaks.Select 16 healthy and approximately 200 kg female yaks during the perinatal period,and randomly divide them into two groups,with eight replicates per group and one yak per replicate.The control group was fed with basic feed,while the experimental group was supplemented with 1.25 g/(kg·d)high sugar feed on top of the basic feed.The pre trial period was seven days,and the main trial period starts from the 21st day before delivery and ends on the 28th day after delivery.Compared with the control group,the average daily weight gain(ADG)of yaks in the experimental group was significantly increased(P＜0.05).Compared with the control group,on the 14th day before delivery,the serum glutathione peroxidase(GSH-Px)activity in yaks was extremely increased(P＜0.01).Compared with the control group,on the 7th day before delivery,the levels of growth hormone(GH),urea nitrogen(BUN),alkaline phosphatase(ALP),GSH-Px,and total antioxidant capacity(T-AOC)in yak serum were extremely increased(P＜0.01),while the activity of superoxide dismutase(SOD)in yak serum was significantly reduced(P＜0.05).Compared with the control group,on the day of delivery,the serum levels of GH,BUN,glucose(GLU),ALP,and GSH-Px in yaks were extremely increased(P＜0.01),while the activity of aspartate aminotransferase(AST)in yak serum was extremely reduced(P＜0.01).The levels of estrogen(E2)and progesterone(P4)in yak serum were significantly increased(P＜0.05).Compared with the control group,on the 7th day postpartum,the levels of GH,BUN,GLU,cholesterol(TC),phosphorus(P),GSH-Px,and T-AOC in yak serum were extremely increased(P＜0.01),while the levels of AST,malondialdehyde(MDA),and SOD in yak serum were extremely reduced(P＜0.01),and the activity of ALP in yak serum was significantly increased(P＜0.05).Compared with the control group,on the 14th day after delivery,the levels of GH,albumin(ALB),TC,and P in yak serum extremely increased(P＜0.0l),while the AST activity in yak serum significantly decreased(P＜0.05).Compared with the control group,on the 21st day postpartum,the serum GH content in yaks extremely increased(P＜0.01),and the serum TC content in yaks significantly increased(P＜0.05).The study indicates that high sugar supplementation can improve the growth performance and antioxidant capacity of yaks during the perinatal period.关键词
