试验选择8日龄乌骨杂交鸡102只,随机分为3组,每个处理3个重复,每个重复17只,对照组喂基础日粮,试验组在基础日粮基础上添加1%杜仲粉。结果表明:与对照组相比,日粮中添加1%杜仲粉可提高乌骨杂交鸡的平均日增重,降低料重比;屠宰性能指标均无显著差异,但胸肌率和瘦肉率比对照组分别提高13.96%和5.74%。 A total of 102 black-bone hybrid chickens of 8-day-old were selected and randomly divided into 3 groups, each with 3 replicates, each with 17 replicates. The control group was fed with basal diet supplemented with 1% Eucommia ulmoides powder. The results showed that compared with the control group, the addition of 1% Eucommia ulmoides powder to the diet increased the average daily gain and the weight-loss ratio of the black-bone hybrid chicken, but no significant difference in the slaughter performance. However, the ratio of pectoral muscle to lean The control group increased by 13.96% and 5.74% respectively.
