Livestock biological fermentation feed

Abstract

The invention discloses livestock biological fermentation feed and belongs to the technical field of agricultural feed additives. The livestock biological fermentation feed contains raw materials, namely paper mulberry leaves, folium mori, corn flour, bean pulp, aspergillus oryzae, brewer's yeast, bacillus subtilis, lactobacillus plantarum and light calcium carbonate. A preparation method comprises the following steps: preparing a fermentation agent, sterilizing raw materials, performing solid fermentation, and drying. By using a microorganism solid fermentation method, macromolecule proteinsand fibers in the paper mulberry leaves and the folium mori can be effectively degraded, biological active substances such as small peptides, digestive enzymes and amino acids are generated, and meanwhile, anti-nutrient factors can be effectively reduced; the content of crude proteins of a final finished product is up to 22-26%, the content of the small peptides is as high as 5-10%, the protease activity is up to 100-160U / g, the content of beneficial bacteria is greater than or equal to 500000000 CFU / g, the content of total acids is greater than or equal to 2.5%, and the moisture is less thanor equal to 12%.

Description

technical field

[0001] The invention belongs to the technical field of agricultural feed additives, and in particular relates to a biologically fermented feed suitable for livestock and poultry prepared by using mulberry leaves, mulberry leaves, and fermentation strains. Background technique

[0002] Paper mulberry is a kind of deciduous tree widely distributed in various places in my country. The scientific name of paper mulberry is Broussonetia papyrifera, which belongs to the genus of mulberry in the family Moraceae. It is distributed in North China, South China, Central China, Southwest China and Northwest China. The mulberry tree is a strong positive tree species with strong adaptability, stress resistance and pollution resistance. The mulberry leaf is rich in flavonoids, alkaloids, fatty acids, lipids and amino acids. The crude protein content of the mulberry leaf is as high as 18-24%, and the composition of lysine and methionine is significantly higher than that of co...
