摘    要:选择健康的28日龄断奶的杜长大三元杂交猪48头,随机分为4个处理,每个处理3个重复,每个重复4头猪,分别为对照组(基础日粮)、抗生素组(基础日粮+20 mg.kg-1硫酸粘杆菌素)、益生菌组(基础日粮+0.2%益生菌)及女贞子组(基础日粮+1%女贞子),试验从仔猪28日龄开始到56日龄结束,试验期为28 d。旨在研究日粮中添加女贞子对断奶仔猪生产性能及抗氧化功能的影响。结果表明,女贞子组、抗生素组的平均日增重及平均日采食量均显著高于对照组(P0.05)。女贞子组血清、肝脏中SOD、GSH-PX活性均显著高于对照组(P0.05),血清、心脏、肝脏中MDA含量均显著低于对照组(P0.05)。说明女贞子对仔猪断奶期的生产性能及抗氧化功能有积极作用,且对抗氧化功能的影响优于抗生素。

关 键 词:女贞子  断奶仔猪  生产性能  抗氧化功能

Abstract:This trial was conducted to study the effect of ligustrum lucidum on growth performance and anti-oxidation of weaned piglets.48 Durocx(Landracex Largewhite)weaned piglets(28 d)were allotted to four treatments with three replications per treatment and 4 weaned piglets per replication.The piglets of the control group were given a basal meal diet,and the piglets of the other groups were given a basal meal diet supplemented with 20 mg·kg-1 colistin sulfate(the antibiotic group),0.2%probiotics(the probiotic group) or 1%LL(the LL group).The piglets were given a basal com-soybean meal diet supplemented with the control,20 mg·kg-1 colistin sulfate,0.2%probiotics or 1%LL.The trial period was 28 d,from 28-day-old to 56-day-old.The results showed that supplementation of LL and colistin sulfate all significantly(P<0.05) increased ADG and ADFI of weaned piglets,and supplementation of LL could also significantly(P<0.05) increase the SOD and GSH-PX activity of serum and liver while significantly(P<0.05)induced the MDA content of serum,heart and liver.The results indicated that LL had positive effects on the growth perfor mance and anti-oxidation of weaned piglets,and the effects of anti-oxidation were better than colistin sulfate.
Keywords:Ligustrum lucidum  weaned piglet  growth performance  anti-oxidation
