摘　　要：【目的】试验旨在研究不同混合比例对饲用油菜与麦秸青贮品质的影响。【方法】将饲用油菜与麦秸按不同鲜重比例(饲用油菜:麦秸分别为100%:0%,95%:5%,90%:10%,85%:15%,80%:20%,70%:30%)混合裹包后常温保存,每个处理设置3个重复,在60 d时开包取样,对混贮饲料的发酵和营养物质含量进行测定,同时进行有氧稳定性分析。【结果】结果表明,随着麦秸比例的添加,pH值、粗蛋白含量、可溶性碳水化合物、丁酸含量的比例显著下降,干物质含量、乳酸含量显著增加,粗脂肪含量、乙酸含量、氨态氮含量变化差异不显著,混贮的发酵品质整体呈现升高趋势,混贮的营养品质呈现降低趋势。【结论】综合发酵品质、营养成分、V-Score评分及有氧稳定性分析,饲用油菜与麦秸混贮比例为质量比8:2(混贮含水量为64.97%)时较好。【Objective】This experiment aimed to study the effects of different mixing ratios on the quality of forage rape and wheat straw silage..【Methods】Feed rape and wheat straw were mixed according to different fresh weight ratios(feed rape:Wheat Straw:100%:0%,95%:5%,90%:10%,85%:15%,80%:20%,70%:30%)were stored at room temperature after mixed wrapping.Each treatment was set for 3 repetitions,and the package was opened for sampling at 60 days.The fermentation and nutrient content of the mixed stored feed were measured,and the aerobic stability was analyzed【.Results】The results showed that with the addition of wheat straw ratio,the pH value,crude protein content and soluble protein content increased The proportion of soluble carbohydrate and butyric acid content decreased significantly,the dry matter content and lactic acid content increased significantly,and the changes of crude fat content,acetic acid content and ammonia nitrogen content had no significant difference.The fermentation quality of the mixed storage system showed an increasing trend as a whole,and the nutritional quality of the mixed storage system showed a decreasing trend.【Conclusion】Based on the analysis of fermentation quality,nutritional composition,v-score score and aerobic stability,the mixed storage of feed rape and wheat straw in the ratio of 80%:20%was better.
