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 sour

Example Embodiment

[0035] (2) Shanghai Meinong Biotechnology Co., Ltd., CN102987081A: It relates to a feed flavor with attractant function and a preparation method thereof. The feed flavor includes the following formula by weight: ethyl butyrate 2-6, ethyl lactate Ester 2~5, Butyric acid 2~10, γ-nonanolactone 20~70, γ-caprolactone 5~25, δ-decanolactone 2~15, δ-laurolactone 2~10, butter Ester 2-15, ethyl vanillin 30-80, carrier 500-900; CN102987084A: A feed flavor for premix, characterized in that the feed flavor includes the following components and parts by weight content :Γ-nonanolactone 4~20, ethyl vanillin 3~25, pentalactone 0.3~2, ethyl maltol 1~8, dihydrocoumarin 1~10, benzyl alcohol 4~20, Ethyl lactate 4-20, ethyl butyrate 5-20, carrier 100-800. Test conditions: 23-day-old weaned piglets (Du Changda), with an initial weight of about 6.19 kg, and the addition amount of the feed attractant 108A was 350 g / T.

[0036] In the above two patents, the maximum use amount of ethyl butyrate in the mo...

Example Embodiment

[0060] Example 1

[0061] (1) In a 2000L enamel reactor, add 1000kg of 99% butyric acid, 450kg of methanol, and 25kg of sulfamic acid in sequence, heat to reflux at 80℃, and react for 8h to obtain a reaction liquid; the above reaction liquid is successively cooled and filtered After the sulfamic acid is filtered out, it is washed with sodium bicarbonate solution with a mass concentration of 10% to remove the acidic substances and unreacted butyric acid and methanol in the reaction solution. Let it stand. The upper layer is methyl butyrate and the lower layer It is water, then dried with anhydrous sodium sulfate to remove water, and finally distilled to collect the fraction from 98°C to 110°C to obtain 1142 kg of methyl butyrate with a purity of 99.3%, with a yield of 98.5%.

[0062] (2) Mixing the above methyl butyrate and white carbon black uniformly to obtain a feed additive with a mass percentage of 60% methyl butyrate.

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...
