The Different Proportion of Composite Bacteria and the Effect of the Content of Each Bacteria in the Solid Fermentation Feed and the Effect of the Content of Each Bacteria and Nutritional Ingredients
This experiment explores the best fermentation process of composite probiotic fermentation feed through different composite bacteria ratio and addition of fermentation straw feed.Test selection of lactic acid bacteria,yeast,and Bacillus is a fermented bacteria.It consists of lactic acid bacteria and yeast and Bacillus composition and different additives.There are 9 groups,fermentation time 48 h,fermentation water content 45%,detection of different test group the number of pH,nutritional indicators,and lactobacillus,yeast and deoderma spores of the feed,thereby determining the best proportion and addition of composite bacteria fermentation feed.Results show that the proportion of lactobacillus,Bacillus and yeast is 1.2∶1.2∶1,and the amount of addition is 9%,which is the best ratio and addition.Compared with before fermentation,the protein content is increased from 8.98%to 9.36%,and the neutral washing fiber content was reduced from 35.26%to 34.45%.
