Problems solved by technology

[0003] However, butyric acid and sodium butyrate have a strong odor, which will have adverse effects on human physical and mental health and environmental protection, so butyric acid and sodium butyrate should not be directly used in feed
In response to the above defects, the researchers used enteric coating materials such as polyacrylic acid resin and monoglyceride stearate to coat sodium butyrate and calcium butyrate, which can prevent butyric acid from being absorbed by the stomach when it passes through the stomach. Ordinary energy feed sources can cover the stench of butyric acid; however, the cost of the above-mentioned coating materials is too high relative to low-cost feeds, so after nearly ten years of promotion, they have not been widely accepted and used in feeds. heavily used in
[0004] At present, tributyrin is a widely recommended additive in the feed field in the past two or three years, but tributyrin tastes very bitter and astringent, and has no fragrance. Adding a little more may affect the palatability of the feed. It is also not conducive to the application in feed

Abstract

The invention provides a feed additive and a preparation method thereof. The feed additive comprises butyric acid monohydric alcohol ester, wherein the butyric acid monohydric alcohol is prepared from butyric acid and monohydric alcohol. Compared with tributyrin and enveloped sodium butyrate in the prior art, the butyric acid monohydric alcohol ester in the feed additive is good in palatability, free of smell and low in cost, a butyric acid biological function can be relatively well achieved, the production performance of bred animals can be improved, and the addition concentration of the feed additive in a feed is 10-10000mg / kg.

Description

technical field [0001] The invention relates to the technical field of feed, more specifically, relates to a feed additive butyric acid monohydric alcohol ester providing the biological function of butyric acid and a preparation method thereof. Background technique [0002] Additives such as butyric acid, sodium butyrate, coated sodium butyrate and tributyrin have been widely used in animal feed, which can promote the intestinal development of farmed animals and repair the damaged cells of the intestinal mucosa, and It has a good effect in providing intestinal cell nutrition to farmed animals, maintaining intestinal health, reducing animal diarrhea and disease occurrence. [0003] However, butyric acid and sodium butyrate have a strong odor, which will have adverse effects on human physical and mental health and environmental protection, so butyric acid and sodium butyrate should not be directly used in feed. In response to the above defects, the researchers used enteric co...
