| 摘要: |
| 在人畜争粮、饲料资源十分缺乏的宁南偏旱区,利用当地养鸡专业户所产废弃物——鸡粪进行微发酵后,使鸡粪中的粗蛋白质含量比原来提高75.44%,粗纤维含量降低28.56%,总氨基酸含量提高51.07%。结果表明,应用此项技术不但可以有效地提高鸡粪中大多数营养物质含量和改善适口性,而且为解决鸡粪的再利用和当地饲料资源的缺乏问题开辟了新的途径。 |

| Abstract: |
| The method of micro-fermentation of poultry waste was studied to resolve the lack of local forage resources in the semiarid areas and semiarid areas liable to droughts in the south part of Ningxia.The content of crude protein and total amino acid was increased by 75. 44% and 51.07%, respectively. The content of crude fiber was decreased by 28.56%. The results proved that the lack of forage resources could be effectively resolved, and micro-fermentation of poultry waste could significantly increase nutrients of poultry waste in the semiarid areas and semiarid areas liable to droughts in the south part of Ningxia. |
