Dorking microorganism viable bacteria fermentation concentrated feed and production method thereof

Abstract

The invention discloses a dorking microorganism viable bacteria fermentation concentrated feed and a production method thereof. The dorking microorganism viable bacteria fermentation concentrated feed is prepared by mixing the following materials: 30-40% of biological decomposition bean pulp, 8-10% of polypeptide biological blood powder, 40-46% of mixed feed meal, 8-12% of feed additive and 1-5% of animal oil. In the feed, feed use ratio is improved by exogenous enzyme and microorganism fermentation; by the beneficial microorganism viable bacteria, flora in a dorking intestinal tract can be regulated to be balanced to improve the anti-stress capability of the dorking; and organic acid and bacteriocin generated by microorganism metabolism can inhibit and kill pathogenic bacteria in feed and the dorking body. The dorking microorganism viable bacteria fermentation concentrated feed does not need to add any antibiotic substance, can effectively inhibit undesirable bacteria growth, regulate the balance of egg and meat intestinal flora, and improve immunity; and chicken has abundant nutrition and does not contain any substance harmful to the human body.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and relates to a broiler feed and a production method thereof, in particular to a microbial fermented concentrated feed suitable for broiler chickens without antibiotics, hormones and harmful additives and a production method thereof. Background technique [0002] Chicken is a food commonly used by people, and it is also one of the important nutrients. In order to improve the production performance of broiler chickens and prevent bacterial diseases, the method adopted in the early stage is to add some antibiotics, such as aureomycin, oxytetracycline, bacitracin zinc, etc., in broiler feed. This method is simple and can achieve the desired effect, but its negative effects are: 1. The antibiotics that have not been metabolized accumulate in the chicken, causing the antibiotics in the chicken to exceed the standard, or even seriously exceed the standard, endangering the health of consumers; 2. L...

Problems solved by technology

Among these additives, organic acids can lower the pH value of the intestinal tract, inhibit the growth of harmful bacteria, and promote the proliferation of beneficial bacteria. However, due to their high production costs and corrosiveness to production equipment and troughs, their application is limited. ;Enzyme preparations can improve feed utilization, reduce the side effects of non-starch polysaccharides and other anti-nutritional factors, and reduce the incidence of nutritional diarrhea, but there are problems such as unstable enzyme activity and inaccurate effects; oligosaccharides can enhance animal immunity , promote the multiple activities of animal intestinal beneficial bacteria proliferation and direct adhesion to harmful bacteria, but the impact of oligosaccharides on animal physiological functions is closely related to factors such as animal feed, animal stage, and animal physiological state. The use of oligosaccharides is limited; the research on Chinese herbal medicine additives has a long history, but the theoretical basis is still unclear, the effects of different prescriptions vary greatly, the amount of addition is large, and the cost is high; microecological preparations help the growth of probiotics in broilers , antagonize the reproduction of pathogenic bacteria, promote feed digestion and absorption, provide nutrition, and enhance animal immune function. The use of ecological preparations; antimicrobial peptides are biologically active small molecule polypeptides induced in organisms, have broad-spectrum antibacterial activity, and have strong killing effects on bacteria. Some antimicrobial peptides are effective against some viruses, fungi, and pathogens. Antimicrobial peptides can also kill worms and cancer cells, and can even improve immunity and accelerate wound healing. However, antimicrobial peptide products are still in the research stage and have not reached the capacity of industrial production.

[0003] So far, there is no live microbial broiler fermented feed that does not use antibiotics and hormones on the market, nor has any antibiotic and hormone-free microbial live broiler fermented feed technology.
