将1日龄肉杂鸡1 200只随机分为4组,A组为对照组,仅饲喂基础日粮;B组在饲喂基础日粮的基础上添加0.5%复方中药;C组添加0.25%益生菌制剂;D组添加0.25%中药-益生菌复合制剂。统计比较各组对生态肉鸡的体质量、料重比及脏器指数的影响。结果表明,添加中药-益生菌复合制剂可显著提高生态肉鸡的体质量、平均日增重,并可降低料重比(P<0.05);对脾脏指数、胸腺指数和法氏囊指数的影响显著(P<0.05)。由此可知,饲粮中添加适量的中药-益生菌复合制剂可提高生态肉鸡的生长性能,促进免疫器官的发育。
1 200-day-old meat hybrid chicken were randomly divided into 4 groups, A group as the control group, fed only basal diet; B group fed basal diet supplemented with 0.5% compound Chinese medicine; C group added 0.25 % Probiotics; Group D added 0.25% Chinese medicine - probiotic compound preparation. The effects of different groups on the body weight, feed-weight ratio and organ index of ecological broilers were statistically analyzed. The results showed that adding traditional Chinese medicine - probiotic compound could significantly improve the body weight, average daily gain, and weight-loss ratio of ecological broilers (P <0.05), and had significant effects on spleen index, thymus index and bursa index (P <0.05). It can be seen that adding appropriate amount of traditional Chinese medicine in the diet - probiotic compound can improve the growth performance of ecological broilers and promote the development of immune organs.
