摘　　要：试验选择64头28±2日龄断奶约克夏仔猪,公母各半,随机分为4个处理组,每个处理组4个重复,每重复4头。对照组饲喂基础日粮,试验组在基础日粮中分别添加0.5%、1%和1.5%女贞子。研究在日粮中添加女贞子对断奶仔猪生产性能及血液生化指标的影响。结果表明,添加1%、1.5%女贞子可显著提高仔猪的平均日增重(P<0.05),日粮中添加不同水平的女贞子均可显著降低断奶仔猪的腹泻率,提高血清中总蛋白含量(TP),降低血清中甘油三酯(TG)含量(P<0.05)。添加1%和1.5%女贞子可显著降低其血清谷丙转氨酶(ALT)活性,提高断奶仔猪血清中高密度脂蛋白(HDL)含量(P<0.05)。日粮中添加女贞子可调节断奶仔猪机体的脂类代谢,降低转氨酶活性,从而提高其部分生长性能。The present study was conducted to evaluate effects of dietary supplementation with different levels of Ligustrum lucidum（LL） on antioxidant status and blood biochemical indices of weaned piglets.Sixty-four 28-day-old Yorkshire pigs were randomly assigned to 4 groups with 4 replicates of 4 pigs per pen（2 gilts and 2 barrows） for a 28-day＇s growth experiment.Testing groups were fed basal diet supplemented with 0.5%,1% and 1.5 LL,respectively.Control group was fed a corn-soybean meal basal diet.The results showed that diets supplemented with 1% and 1.5% LL significantly increased ADG of piglets（P0.05）.As compared to the control,concentration of serum TG,incidence of diarrhea were decreased and TP concentration of sera was enhanced by 0.5%,1% and 1.5% LL supplementation（P0.05）.Serum ALT activity was reduced and content of HDL was increased by 1% and 1.5% LL supplementation（P0.05）.Lipid metabolism of organism was modified and activities of sera aminotransferase were reduced by LL supplementation,which improved the partial growth performance.
