摘要 [目的]开发或利用大宗非粮型单细胞蛋白饲料资源。[方法]利用鸡粪发酵物、发酵配合饲料,按不同比例分别与常规配合饲料和自配无抗配合饲料混合,同时利用10%酿酒酵母培养物和90%常规配合饲料混合,进行育肥猪饲喂试验。通过比较各试验组与对照组的饲喂效果,探讨鸡粪发酵物和发酵自配无抗配合饲料的最佳添加比例,分析酿酒酵母培养物的饲喂效果。[结果]添加自配无抗配合饲料的试验料肉比均低于对照组;鸡粪发酵物添加试验组中,用15%鸡粪发酵物替代常规配合饲料的试验组A3料肉比最低;发酵配合饲料添加试验组中,添加20%发酵自配无抗配合饲料+80%自配无抗配合饲料的试验组B2的料肉比最低;使用10%酿酒酵母培养物替代常规配合饲料试验组C1的料肉比低于对照组。经济效益分析表明,添加鸡粪发酵物的试验组中A2组毛利润最高,添加发酵配合饲料的试验组中B2组毛利润最高。[结论]研究可为新饲料原料的开发、原料发酵处理等提供理论参考,并为实现农牧废弃资源的高效和增值利用奠定基础。 [Objective]To develop and utilize a large amount of non-grain single cell protein feed resources.[Method]Chicken manure fermentation or fermented compound feed was mixed with conventional compound feed and self-made non-resistant feed at different ratio respectively.The feeding effect in each experimental group and control group was compared.The optimum adding proportion of chicken manure fermentation and fermented self-made non-resistant feed was discussed.The feeding effect of Saccharomyces cerevisiae culture was analyzed.[Result]The feed-gain ratio in the experimental groups with adding self-made non-resistant feed were lower than that in control group.Among the experimental groups with adding chicken manure fermentation,the feed-gain ratio in experimental group A3 with adding conventional compound feed in replacement of 15%chicken manure fermentation was the lowest.Among the experimental groups with adding fermented compound feed,the feed-gain ratio in experimental group B2 with adding 20%fermented self-made non-resistant feed+80%self-made non-resistant compound feed was the lowest.The feed-gain ratio in experimental group C1 with adding conventional compound feed in replacement of 10%S.cerevisiae culture was lower than that in control group.The analysis of economic benefits showed that the gross profit in A2 experiment group was the highest among the experimental groups with adding chicken manure fermentation,and the gross profit in B2 experiment group was the highest among the experimental groups with adding fermented compound feed.[Conclusion]The study could provide theoretical reference for the development of new feed ingredients and the fermentation of raw materials and lay the foundation for efficient and value-added utilization of agro-pastoral waste resources.
