摘要
【研究目的】提高玉米秸的饲用价值;【方法】对玉米秸进行了不同的氨化处理并饲喂育成牛;【结果】玉米秸经盐水复合氨化处理,其粗蛋白含量、采食量和日增重比对照组分别提高了124.25%、22.26%和56.25%,每千克增重饲料成本降低15.63%。【结论】建议大力推广使用盐水复合氨化玉米秸秆,以促进养牛业的快速发展。
[OBJECTIVE]Different ammoniate methods were used for corn straw in order to improve its nutritive value. [METHOD]Then the straw were fed the heifer to study its feeding effects. [RESULTS]The result showed that： the CP content, DMI and ADG of the corn straw treated with multi-ammoniated increased by 124.25%, 22.26% and 56.25% than control group respectively, the feedstuff cost （per kg gain） decreased by 15.63% than control group.[CONCLUSION]It was recommended to extend multi-ammoniated corn straw so that accelerating the development of cattle industry.
