Wheat grain composite reduced-antibiotics microbial feed additive

Abstract

The invention relates to a wheat grain composite reduced-antibiotics microbial feed additive. The feed additive includes wheat grains, saccharomyces cerevisiae CCTCC M 2019051 is added into the feed additive, and one or more selected from bacillus polymyxa CCTCC M 2019024, bacillus natto CCTCC M 2019025 and lactobacillus plantarum CCTCC M 2019026 are added into the feed additive, wherein the addition amount of the saccharomyces cerevisiae CCTCC M 2019051 is 0.5-5%, and the addition amount of the total microorganisms is 1-8%. The feed additive not only has low costs and a simple preparation process, but also can effectively enhance the immunity and disease resistance of livestock and poultry, can effectively replace antibiotics, and achieve the effect of reducing the dosage of the antibiotics.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to a feed additive compounded with wheat grains to reduce anti-bacteria. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or pasture. The feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives and more than ten varieties of feed materials. In actual feeding, farmers can add some feed additives to supplement nutrition or reduce diseases according to needs. [0003] At present, during large-scale farming, various antibiotics and health care and metabolic regulation drugs are generally added to the feed. Antibiotics have been used as feed additives in the feed industry for more than 40 years. They have played a positive role in preventing anim...

AI Technical Summary

Problems solved by technology

First, the extensive use of antibiotic additives can lead to drug resistance in pathogenic bacteria

Secondly, a large amount of antibiotics will remain in the body of poultry, affecting the immune effect of humans and animals; long-term use, especially abuse, will increase the amount of antibiotic residues in the body, on the one hand may induce durable bacteria, on the other hand Residual antibiotics have reduced the immune effect of immune vaccines, laying a hidden danger for the control of epidemics

Finally, the extensive use of antibiotics is prone to cross-infection of pathogenic bacteria. The use of antibiotics, especially excessive use, will destroy the balance of microorganisms in the intestinal tract. On the one hand, it will reduce the microorganisms that are highly sensitive to antibiotics in the gastrointestinal tract. Bacteria with poor sensitivity take advantage of the opportunity to reproduce in large numbers, causing an imbalance in the microbial state; on the other hand, after the microorganisms in the body are eliminated by antibiotics, conditions are created for the invasion and reproduction of microorganisms outside the body, which is prone to pathogenic cross-infection
