| 摘 要： | 分别用0．5％和0．7％甲醛处理豆粕和棉籽粕，研究不同水平甲醛对豆粕和棉籽粕蛋白质的保护效果。结果表明：甲醛处理可以大幅度降低饲料蛋白质的降解率，0．7％甲醛处理可使豆粕和棉籽粕过瘤胃蛋白分别提高51．9％和26．3％，0．5％甲醛处理可使豆粕和棉籽粕过瘤胃蛋白分别提高44．7％和10．4％，两水平甲醛均可有效保护饲料蛋白质。从降解动力学分析，甲醛处理降低了蛋白质的快速降解部分和降解速度，从而降低了蛋白质的动态降解率。结果还表明甲醛保护豆粕的效果优于棉籽粕。 |

| Abstract: | The effects of treating soybean meal(SBM) and cottonseed meal(CSM) with formaldehyde at 0.5% and 0.7% of CP content respectively,which lied on CP degradability in the rumen were investigated.The trial results showed:(1)CP effective degradability,the immediately degraded fraction and degraded rate were decreased by formaldehyde treatment.With 0.7% formaldehyde treatment,CP effective degradability was decreased by 51.9% and 26.3% for SBM and CSM respectively. With 0. 5% formaldehyde treatment, CP effective degradability was decreased by 44.7% and 10.4% for SBM and CSM respectively.(2)Formaldehyde treatment provides better protection of protein in SBM than in CSM. |
| Keywords: | formaldehyde soyabean meal cottonseed meal rumen protein degradability |
