Abstract: A novel feed was produced using banana peel as main substrate in this study.In details,the banana peel was mixed with little urea,wheat bran and sweet potato firstly.Then,the mixture was extruded by twin-screw extruder and inoculated with Candida utilis for fermentation.The effects of urea amount,sweet potato amount,wheat bran amount,inoculum and fermentation time on the protein content in feed were studied.The optimum fermentation conditions were confirmed by orthogonal test(4 factors and 3 levels),that was:urea 3%,sweet potato 10%,wheat bran 25%,inoculum 10%,fermenting time 3 d.After fermentation,the protein content of the feed reached 27.87%.With this technology,the protein in feed can be improved effectively.It can be used to produce protein feed.
