[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.
