Intermediate-stage compound pig feed containing fermented snow pear juice and cottonseed dregs fermented by Lactarius deliciosus

Abstract

The invention discloses intermediate-stage compound pig feed containing fermented snow pear juice and cottonseed dregs fermented by Lactarius deliciosus. The intermediate-stage compound pig feed is prepared from, by weight, 70-80 parts of cottonseed dregs, 10-12 parts of wheat, 40-50 parts of corn, 25-30 parts of corn protein powder, 2-3 parts of medical stone, 8-10 parts of wheat short, 50-55 parts of snow pears, 10-14 parts of Fructus Oryzaa Germinatus, saccharomycetes, Lactarius deliciosus strains, zinc sulfate, choline chloride, calcium hydrophosphate, DL-methionine, L-threonine, L-lysine, neutral protease and an appropriate amount of water. The intermediate-stage compound pig feed containing the fermented snow pear juice and the cottonseed dregs fermented by the Lactarius deliciosus has the advantages that the Lactarius deliciosus is used for fermenting the cottonseed dregs, so that the content of raffinose and the content of free gossypol in the cottonseed dregs can be decreased, animals can absorb nutritional substances more effectively and toxicity of the cottonseed dregs is reduced; through synergistic effect of double enzymes on the corn protein powder, protein catalytic sites are increased, so that corn protein is decomposed into micromolecular corn peptides low in relative molecular weight more effectively; the intermediate-stage compound pig feed is capable of improving animal digestion functions and feed palatability, preventing diarrhea and flatulence, enhancing immunity and improving meat quality, thereby completely satisfying the requirements of people on green food and healthy consumption nowadays.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a medium-term compound feed for pigs fermented with pear juice pine milk mushroom and fermented cotton meal. 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 degrade the free ...

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
