| 摘 要： | 【研究目的】为提高麦秸的饲用价值，【方法】对麦秸进行了不同的氨化处理并饲喂肉牛试验，【结果】结果表明：麦秸经造纸废液复合氨化处理，其粗蛋白含量和日增重比对照组分别提高了111.40%和45.28%，采食量显著增加(P<0.05)，每千克增重饲料成本降低25.04%。【结论】建议在秸秆的氨化处理中推广使用造纸废液复合氨化处理技术，以提高养牛业的经济效益。

| Abstract: | 【OBJECTIVE】Different ammoniated methods were used for wheat 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 treat of multi-ammoniated wheat straw was the most effective, the CP content, and ADG increased by 111.40%, and 45.28% than control group respectively, DMI increased significantly(P<0.05), the feedstuff cost (per kg gain) decreased by 25.04% than control group.【CONCLUSION】It was recommended to extend multi-ammoniated wheat straw so that accelerating the development of cattle industry. |
