Evaluation Effects of Feed Compound Probiotics to Degrade Crude Fiber in Corn Husk?Rice Bran Mixed Raw Materials
摘要
Abstract
This experiment was conducted to study the effects of feed compound probiotics to degrade crude fi?ber in corn husk?rice bran mixed raw materials. The experiment used corn husk?rice bran mixed raw materials ( corn husk 67.0%, rice bran 17.4%, cottonseed meal 15.0%, brown sugar 0.3% and urea 0.3%) as the fer?mentation raw material, based on the previous study results, the inoculation proportions of Lactobacillus, Ba?cillus, yeast and Aspergillus niger were 5%, 1%, 5%, 3%( 3% group ) and 5%, 1%, 5%, 5%( 5%group) , respectively, and used the dynamic sampling experiment to analyze the change curves of nutrient in?dex during 9 days fermentation. The results showed that at fermentation day 9, the neutral detergent fiber con?tents of 3% group and 5% group were decreased by 30.84% and 29.04%( P＜0.01) , the acid detergent fiber contents were decreased by 24.25 % and 30.53%( P＜0.01) , the crude protein contents were increased by 30.43% and 37.76%( P＜0.01) , and the reducing sugar contents were increased by151.85% and 170.37%( P＜0.01). The neutral detergent fiber content at day 3 of 3% group was significantly higher than that of 5%group ( P＜0.01) , and the neutral detergent fiber content at day 5 was significantly lower than that of 5% group ( P＜0.05) ; the reducing sugar content at day 9 of 3% group was significantly lower than that of 5% group ( P＜0.05). Dynamic sampling data analysis showed that corn husk?rice bran mixed raw materials had the best fermentation effect when the inoculation proportions of Lactobacillus, Bacillus, Yeast and Aspergillus niger in the feed compound probiotics were 5%, 1%, 5% and 5%, when fermentation time was 5 to 7 days, the loss rate of dry matter could be effective reduced. In conclusion, the corn husk?rice bran mixed raw materials fer?mented by feed compound probiotics can reduce the contents of neutral detergent fiber and acid detergent fiber in corn husk?rice bran mixed raw materials, improve the contents of crude protein and reducing sugar, and im?prove the feed quality.[ Chinese Journal of Animal Nutrition, 2019, 31(10) :4893?4900]关键词
