Compound middle-stage pig feed prepared by crowndaisy chrysanthemum extract and containing cottonseed meal fermented by lactarius deliciosus

Abstract

The invention discloses compound middle-stage pig feed prepared by crowndaisy chrysanthemum extract and containing cottonseed meal fermented by lactarius deliciosus. The lactarius deliciosus-fermented cottonseed meal compound middle-stage pig feed is prepared by, 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, 15-20 parts of cassava flour, 5-7 parts of dried small shrimps, 6-7 parts of lotus leaves, 40-50 parts of crowndaisy chrysanthemum, lactarius deliciosus strain, zinc sulfate, choline chloride, calcium hydrophosphate, DL-methionine, L-threonine, L-lysine, neutral protease and an appropriate amount of water. The compound middle-stage pig feed has the advantages that the cottonseed meal fermented by the lactarius deliciosus can reduce the content of raffinose and free gossypol in the cottonseed meal, increase the nutritional substance absorption of pigs and reduce cottonseed meal toxicity; double-enzyme-synergistic-action corn protein powder increases protein catalytic sites and can effectively decompose corn protein into small-molecule corn peptides with low relative molecular mass; the compound middle-stage pig feed can accelerate metabolism, promote pig growth, enhance pig immunity, increase pig reproduction ability and production performance, improve the anti-oxidation ability of the pigs and effectively relieve oxidative stress.

Description

Technical field [0001] The invention relates to the technical field of feed, in particular to a medium-term compound feed for pigs with Lactarius edulis fermented cottonseed meal prepared from Chrysanthemum vulgare extract. Background technique [0002] The article "Study on the Detoxification Conditions of Lactarius pineapple Solid Fermented Cotton Meal" 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 cotton meal in my country is about 6 million tons, the protein contains 30-45%, and it is rich in various amino acids, vitamin B and E vitamins. However, the cottonseed meal contains free gossypol, anti-nutritional factors, and the imbalance of amino acid types, which limits its wide application in the breeding industry. The microbial fermentation detoxification method is to use the powerful enzyme system in the microorganism to effectively degrade the...

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
