研究中草药女贞子原粉作为饲料添加剂对AA肉鸡生产性能和免疫功能的影响.选择360只AA内鸡公雏随机分为4组,对照组为空白组,饲喂基础日粮,抗生素组在基础日粮中添加5mg·kg~(-1)黄霉素,0.5%女贞子组在基础日粮中添加0.5%女贞子原粉,1%女贞子组在基础日粮的基础上添加1%女贞子原粉,试验期为42 d.结果表明,添加女贞子原粉可以显著提高后期肉鸡的日增重;日粮中添加0.5%、1%女贞子原粉能加快胸腺和脾脏的发育,并延缓法氏囊的退化;添加女贞子原粉可以提高血清中的溶菌酶活力,其中以42 d添加1%女贞子组最为显著(P<0.05);女贞子原粉可提高血清中激素水平以及免疫球蛋白的含量,1%女贞子组效果最好.直接添加女贞子原粉能够提高后期肉鸡的日增重,增强AA肉仔鸡的免疫功能,其中以1%女贞子组的添加效果较好.

Effects of Ligustrum lucidum(LL)of original powder on.immunity of broilers are studied.360 broilers of 1-day-old were randomly assigned to four groups.The blank was provided with basal diet,the antibiotic group was provided with basal diet and with addition of 5 mg·kg~(-1) flavomycin,0.5%group was provided with basal diet and with addition of 0.5%LL,1%group was provided with basal diet and with addition of 1%LL.The broilers were fed their respective diets from 1-day old to 42-day old.The results showed that adding the LL of original powder could significantly improve the daily gain of broilers in the later;0.5%and 1%group could speed up the development of the spleen and thymus;and slow down the degradation of bursa.LL powder can improve the original serum lysozyme vitality and 42-day-old,1% group had the most significant effect(P<0.05).LL powder could increase serum hormones levels and immunoglobulin content.and 1%group was the most effective.Diect adding LL powder could impove the daily gain of broilers in the later abd enhance broiler's immunity,1%group had the better effect.
