【摘要】 试验选择健康1日龄商品代AA肉鸡96只,随机分成试验组Ⅰ、Ⅱ和对照组,每组4个重复,每个重复8只,试验期49 d。1~21日龄阶段,试验组Ⅰ、Ⅱ均饲喂基础日粮+0.1%苜蓿总甙;22~35日龄和36~49日龄阶段,试验组Ⅰ饲喂基础日粮+0.1%苜蓿总甙,试验组Ⅱ饲喂基础日粮+0.2%苜蓿总甙。试验结果如下:①添加苜蓿总甙除22~35日龄试验组Ⅰ肉仔鸡采食量有显著差异(P<0.05)外,其他各试验组各阶段生长性能差异均不显著(P>0.05)。②添加苜蓿总甙对不同日龄仔鸡血清和肝脏GSH-Px、SOD和MDA水平有不同程度地影响。更多还原

【Abstract】 A total of 96 1-day healthy AA broilers of commercial strain were chosen in this experiment,the birds were divided into 3 groups: control,test groupⅠand Ⅱ,four replicates of 8 birds were in a group.The total experimental time was 49 days.During 1～21 days,birds in test groupⅠand Ⅱ were fed basal diet supplemented with 0.1% alfalfa glycosides,respectively.During 22～35 days and the 36～49 days,birds in groupⅠwere fed basal diet supplemented with 0.1% alfalfa glycosides,and birds in groupⅡ were fed basal diet supplemented with 0.2 % alfalfa glycosides.The results showed that: ①Dietary supplementation of 0.1% alfalfa glycosides effects significantly the feed intake(FI) of the broilers in 22～35 days,but the performance difference of other groups and experimental times is not significant(P>0.05).②Dietary supplementation of alfalfa glycosides to the different date age has the influence on serum and liver GSH-Px,SOD and MDA level in different extend更多还原
