Feed additive capable of replacing antibiotics and application of feed additive

Abstract

The invention discloses a feed additive capable of replacing antibiotics and application of the feed additive. The feed additive is prepared from the following raw materials in weight percent: 10 % to 20% of glyceryl monolaurate, 20% to 40% of didansylhistamine, 30% to 60% of glycerin monostearate and 0 to 40% of a carrier. The feed additive provided by the invention is prepared by taking the glyceryl monolaurate, the didansylhistamine and the glycerin monostearate as the main raw materials and compounding according to a proper ratio and can replace the antibiotics in a piglet cultivation process; the disease-resisting capability of piglets is improved, the development of intestinal tracts is promoted and the functions of the intestinal tracts are improved; the daily gain and feed intake are remarkably improved, the diarrhea rate and the death and culling rate are remarkably reduced, the feed conversion ratio is improved, the growth and development are promoted, the economic benefits of cultivation are improved, the utilization of the antibiotics is reduced, the environment pollution is reduced, and the green, safe and healthy development of a pig industry is facilitated.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive that can replace antibiotics and its application. Background technique [0002] In the high-density large-scale breeding mode, in order to make the pigs go out of the market as soon as possible and reduce illness and death, heavy metals, hormones, antibiotic additives and various drugs are often used in excess of the standard in the piglet breeding process, and these substances remain in the piglets. Entering the environment with the excrement from farming seriously affects human health. [0003] With people's attention to food safety and human health, the requirements for meat products have changed, and it is urgent to market green, safe and nutritious products. Therefore, it is necessary to use safe, efficient, and green functional food ingredients to develop feed additives to replace the application of antibiotics in piglet breeding, not only without he...

AI Technical Summary

Problems solved by technology

[0012] However, mechanistic studies have found that the additives used as antibiotic substitutes need to consider issues such as palatability, intestinal environment balance, and intestinal flora balance. If used improperly, it may cause performance decline, intestinal environment imbalance, and bacterial flora imbalance; The feed additives disclosed in the above documents that can be used to replace antibiotics can replace antibiotics to a certain extent, but there are problems such as the feed additive has too much or too little bactericidal effect in livestock and poultry, which affects the growth of livestock and poultry. The replacement effect of antibiotics is not good, and it still needs to be improved, and the effect of the ratio of monolauric acid / diglycerides on the balance of the intestinal environment and the balance of intestinal flora has not been considered
