本文研究中草药酵母硒与微量元素硼联用对肉鸡生长性能的影响。1200羽1日龄健康 AA 肉鸡随机分为对照组和试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组，每组240羽；对照组饲喂玉米-豆粕型基础日粮，各试验组日粮设计为基础日粮﹢4%中草药酵母硒﹢硼（硼含量分别为0、5、10、15 mg / kg），试验期42d。结果显示，试验Ⅱ- Ⅳ组21d 和42d 肉鸡平均体重和日增重均不同程度高于对照组和试验Ⅰ组，其中21d 试验Ⅱ、Ⅳ组和42d 试验Ⅱ、Ⅲ组肉鸡平均体重，1-21d 试验Ⅱ组及22-42d 和1-42d 试验Ⅱ -Ⅳ组平均日增重显著或极显著高于对照组（P〈0.05或 P〈0.001）；42d 试验Ⅱ、Ⅲ组肉鸡平均体重及22-42d 和1-42d 试验Ⅱ、Ⅲ组平均日增重显著高于试验Ⅰ组。各试验组不同日龄阶段料重比均不同程度低于对照组和试验Ⅰ组，其中22-42d 和1-42d（全期内）试验Ⅱ -Ⅳ组肉鸡的料重比降低较为明显。试验结果表明，中草药酵母硒与微量元素硼联用对肉鸡的生长性能有明显促进作用，可明显提高肉鸡的平均体重、日增重和饲料转化率，并以添加0.4%中草药酵母硒和5-10 mg / kg 硼的联用效果最好。

英文摘要：

To determine the effect of Se - enriched yeast cultured Chinese medicine（SEYCCM）and Boron on growth performance of broilers,1200 one - day - old healthy Arbor Acre（AA）broilers were randomly divided into five groups and each group had 240 broilers. The five experimental diets were designed as following：the control group was fed with the corn - soybean basal diet and the experimental groups Ⅰ,Ⅱ,Ⅲ and Ⅳwere of-fered basal diet added by 4% SEYCCM with different concentration of Boron（0,5,10,15 mg / kg,respective-ly）for 42 days. From results,compared with the control group and group Ⅰ,the average final weight and average daily gain of the Ⅱ,Ⅲand Ⅳ groups were increased differently. Compared with the control group,the average final weight of Ⅱ and Ⅳ in 21d and that of Ⅱ and Ⅲ in 42d were increased significantly. The average daily gain of Ⅱ group during 1 - 21d and that ofⅡ,Ⅲ and Ⅳ during 22 - 42d and 1 - 42d were significantly higher than that of the control group（P〈 0. 05 or P〈 0. 001）. In groups Ⅱ and Ⅲ,the final average weight in 42d and the average daily gain during 22 - 42d and the 1 - 42d were significantly higher than that in the control group.Meanwhile,the feed / gain ratio of the Ⅱ,Ⅲ and Ⅳ groups was differently decreased than that of the control and groups Ⅰ,and that in 22 - 42d and 1 - 42d was effected significantly. Above results indicate that the complex of SEYCCM and Boron supplemented in basal diet has an beneficial effect on broiler growth performance and the effect of 5 and 10 mg / kg boron with 4% SEYCCM was the best.
