Active peptide feed additive and its preparation method and use

Abstract

The present invention relates to an active peptide feed addictive, as a mixture of one or more plant protein and animal protein, which is the product of the following steps: fermenting and degrading the mixture through bacillus and the like, controlling the degree of hydrolysis at 20-35%, obtaining a fermentation supernatant after a separation post-processing process, concentrating drying the supernatant or directly adsorbing the supernatant onto the carrier, and then low temperature drying it. Said active peptide feed addictive is capable of obviously depressing development of bacillus coli and salmonella, and can prevention and cure diarrhea caused by bacilli or lienteric diarrhea; can exert its functions at a very low concentration, with a very intense effect; can regulate stomach and intestine bacterium group and promote animals digestion functions; can excite animal immune function, reinforce animal disease resistance against a plurality of epidemic diseases and greatly reduce the morbidity and death rate; can promote animal development and improve the growth velocity; can improve the feed use ratio and reduce production costs. Applications of the microorganism fermentation degradation method provided by the present invention have a low fabricating cost, and the obtained peptides have many kinds and high content, without environment pollutions.

Description

field of invention [0001] The invention relates to an active peptide feed additive, in particular to an active peptide (or oligopeptide) feed additive made from animal and vegetable proteins and a preparation method thereof. Background technique [0002] Since the 1950s, antibiotics, chemically synthesized drugs, hormones, β-stimulants, heavy metals, sedatives and other growth-promoting health care agents have been widely used in animal feeding and feed, leading to the following problems: drugs in livestock, poultry and aquatic products The residues are serious, directly endangering human health; the quality of livestock and poultry products has declined, lacking market competitiveness and trust; bacterial resistance has increased, and drug-resistant strains have increased, threatening human safety; destroying the ecological environment, etc. Due to the many side effects of antibiotics, scientists have been looking for alternatives to antibiotics for the past 20 to 30 years....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the large amount of active peptide feed additive prepared in the prior art, the product function is not clear, the efficacy is not obvious, the peptide molecular weight is large and still has antigenicity, it is easy to cause antigen allergic reaction, and the preparation cost is high and it is not easy The disadvantages of popularizing and using in the animal breeding industry, so as to provide a feed with low addition amount and clear function, which can improve the absorption and utilization of nutrients (such as protein, minerals, vitamins, etc.) by animals, and increase the output of milk, meat and eggs. and production capacity, improve the quality and flavor of meat, eggs, and milk, stimulate the development of animal immune organs, improve disease resistance and reduce morbidity, and can significantly improve the water quality of aquatic animal breeding, increase the growth rate and survival rate of aquatic animals, and are widely used Active peptide feed additive for poultry, cattle, sheep, pigs, aquatic products and economic animals, which can be used as a substitute for antibiotics
