Feed additive capable of replacing antibiotics, preparation method thereof and application thereof

Abstract

The invention discloses a feed additive capable of replacing antibiotics, a preparation method thereof and an application thereof. The feed additive capable of replacing antibiotics is composed of a microecological preparation, functional oligosaccharides, organic acid and a carrier; the type and the content of the microecological preparation are: lactobacillus sporogenes with 1.0*108-1.0*109CFU / g, bacillus subtilis with 1.0*108-1.0*109CFU / g; the type and the content of the functional oligosaccharides are: 0.1-0.3wt% of mannan oligosaccharides; the type and the content of the organic acid are: 5-10wt% of lactic acid, 2-5wt% of citric acid and the balance of carrier. The addition of the feed additive in a mixed feed is 3-5kg / T. The feed additive capable of replacing antibiotics can minimize the stress effect of antibiotics on animal body, simultaneously reduce the antibiotics residue in meat, egg and milk. The feed additive capable of replacing antibiotics has significance for protecting human health and ecological environment.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a feed additive for replacing antibiotics, a preparation method and application thereof. Background technique [0002] Recently, domestic food safety incidents have occurred frequently, and the feed industry, which is the upstream of food processing, has also increased the emphasis on safety issues. Since the discovery of pathogenic bacteria resistant to antibiotics in the late 1950s, the safety issues caused by the addition of antibiotics to feed have become the focus of attention. The harm of antibiotics in livestock and poultry breeding is mainly manifested in (1) making pathogenic bacteria resistant to antibiotics, and increasing labor and capital investment in the treatment of livestock and poultry diseases. Many strange diseases have appeared in the breeding now, and the existing veterinary medicines cannot treat them, resulting in high mortality of li...

AI Technical Summary

Problems solved by technology

The harm of antibiotics in livestock and poultry farming is mainly manifested in (1) causing pathogenic bacteria to develop drug resistance, increasing labor and capital investment in the treatment of livestock and poultry diseases

Now there are many strange diseases in breeding, which cannot be treated by existing veterinary medicines, resulting in high mortality of livestock and poultry, and large losses in breeding

(2) Residues in the body, affecting the immune effect of humans and animals

Long-term use, especially abuse, will increase the residual amount of antibiotics in the body

Drug residues in the body, on the one hand, may induce the production of durable drug bacteria, on the other hand, the residual antibiotics will reduce the immune effect of epidemic prevention vaccines, laying hidden dangers for the control of epidemic diseases

(3) prone to cross-infection of pathogenic bacteria

Many researchers have conducted a large number of experiments on single probiotics, functional oligosaccharides, organic acids, or two compound products on livestock and poultry, in terms of production performance, immune function, intestinal flora and feces, etc. Good results have been achieved, but there is no guarantee that they will completely replace antibiotics in terms of effect

There are few attempts on the combined use of probiotics, functional oligosaccharides, and organic acids
