不同赖氨酸源对规模化饲养肉鸡生产性能的影响

Effects of different types of lysine on broiler performance under large-scale feeding

试验研究了不同赖氨酸源(65%赖氨酸硫酸盐和98.5%赖氨酸盐酸盐)对肉鸡生产性能的影响,探讨国产赖氨酸硫酸盐在肉鸡饲料中实际应用的可行性。试验结果表明:整个试验期不同处理组对矮脚黄A公鸡的生产性能影响差别不大,而在综合经济效益分析上,用国产赖氨酸硫酸盐组要好于进口赖氨酸盐酸盐组,所需的增重成本较低,毛利较高,赖氨酸硫酸盐能够替代赖氨酸盐酸盐用于肉鸡饲料中。建议在大型养鸡场中推广应用,以更好地节省成本,提高经济效益。

The test discussed the effects of different lysine sources （65% lysine sulfate and 98.5% lysine-HCl） in order to prove the feasibility of lysine sulfate applied in broiler feed. The results showed that there was no difference on broiler performance between the two kinds of lysine sources. However, the comprehensive benefit analysis indicated that lysine sulfate helped reduce the feed cost and it could be used extensively in broiler production.
