Lactarius deliciosus fermented cottonseed meal pig medium-stage compound feed prepared from fermented wort

Abstract

The invention discloses a lactarius deliciosus fermented cottonseed meal pig medium-stage compound feed prepared from fermented wort. The compound feed is prepared from the following raw materials in parts by weight: 70-80 parts of cottonseed meal, 10-12 parts of wheat, 40-50 parts of corn, 25-30 parts of corn protein powder, 2-3 parts of medical stone powder, 20-25 parts of extruded soybean, 10-12 parts of milk powder, 4-5 parts of white sugar, 60-70 parts of wheat seedling and appropriate streptococcus thermophiles, lactarius deliciosus strain, zinc sulfate, choline chloride, calcium hydrogen phosphate, DL-methionine, L-threonine, L-lysine, neutral protease and water. The lactarius deliciosus fermented cottonseed meal can reduce the content of raffinose and free gossypol in cottonseed meal and improve the absorption of nutrients by animal and reduce the toxicity of cottonseed meal. Through synergistic effect of two enzymes on the corn protein powder, the protein catalysis sites are increased, and the corn protein can be decomposed more effectively into small-molecule corn peptide with low relative molecular weight. The microbial enzyme generated in the fermentation process can improve the digestive ability of animal, increase the feed intake of livestock and poultry and enhance the productivity of animal; and moreover, the pH in the animal body and blood can be increased, the gastrointestinal function is improved, and the utilization rate of feed is raised.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a medium-term compound feed for pigs prepared by fermenting wort and fermenting cottonseed meal with pine milk mushroom. Background technique [0002] The article "Research on Detoxification Conditions of Cottonseed Meal by Solid-state Fermentation of Pine Milk Mushroom" mentioned that cottonseed meal is a by-product of cottonseed after being pressed or extracted to remove oil, and is an important plant protein feed resource. The annual output of cottonseed meal in my country is about 6 million tons, the protein content is 30-45%, rich in various amino acids, vitamin B and E vitamins, etc. However, because cottonseed meal contains free gossypol, anti-nutritional factors, and the imbalance of amino acid types, its wide application in aquaculture is limited. The microbial fermentation detoxification method is to use the powerful enzyme system in the microorganism to effectively degra...

Problems solved by technology

Raffinose is insoluble in water, so it cannot be digested and absorbed by monogastric livestock, which increases the permeability and liquid retention of the small intestine content, thereby reducing the hydrolysis of nutrients, and due to the weakening of the hydrolysis of nutrients, increases Increase the content of the small intestine, stimulate the peristaltic reflex of the small intestine, thus increasing the speed of feed running in the intestine, and affecting the animal's full absorption of nutrients
