Embodiment 1

[0016] Weigh and weigh 500g of starch and 8000g of γ-aminobutyric acid powder, stir at 30-90rpm for 20min to mix evenly; weigh 500g of hydroxypropylmethylcellulose and dissolve in 10000mL of water to obtain 5% hydroxypropylmethylcellulose Add the above hydroxypropyl methylcellulose solution to the mixture of starch and γ-aminobutyric acid, granulate with shaking, and dry by pulling the wind. Add 500g of glyceride and 500g of resin 2# into 21000mL ethanol solution to fully dissolve it as coating solution; in the coating equipment, the flow rate is 0.1L / min, the inlet air temperature is 50-60℃, the outlet air temperature is normal temperature, and the time is 3.5 h, carry out coating treatment. More than 85% of the product particle size passes through a 20-mesh sieve.

Embodiment 2

[0018] Weigh and weigh 2000g of starch and 5000g of γ-aminobutyric acid powder, and stir for 20min at a speed of 30-90rpm to mix evenly; weigh 1000g of hydroxypropylmethylcellulose and dissolve it in 10000mL of water to obtain 10% hydroxypropylmethylcellulose Add the above hydroxypropyl methylcellulose solution to the mixture of starch and γ-aminobutyric acid, granulate with shaking, and dry by pulling the wind. Add 1,500g of glyceride and 500g of resin 2# into 21,000mL of ethanol solution and fully dissolve it as a coating solution; in the coating equipment, the flow rate is 0.1L / min, the inlet air temperature is 50-60°C, and the outlet air temperature is normal temperature, and the time is 3.5 h, carry out coating treatment. More than 85% of the product particle size passes through a 20-mesh sieve.

Abstract

The invention relates to a preparation method of an animal feed additive gamma-aminobutyric acid coated when passing a rumen. The animal feed additive gamma-aminobutyric acid coated when passing the rumen comprises the following components in percentage by weight: 5%-20% of starches, 5%-10% of hydroxy propyl methyl celluloses, 50%-80% of gamma-aminobutyric acid powder, 5%-15% of glycerol stearate and 3%-5% of resins 2#. The preparation method enables the gamma-aminobutyric acid powder not to be fermented and degraded when passing the rumen of a ruminant and to be released in a long-acting way in intestinal tracts by carrying out microencapsulating coating processing on the gamma-aminobutyric acid powder, and enhances the effective absorption and utilization of the gamma-aminobutyric acid powder in the intestinal tracts, thereby enabling the physiological functions to be sufficiently played in the ruminant.

Description

technical field [0001] The patent of the present invention relates to a preparation method of gamma-aminobutyric acid passing through the rumen coating of an animal feed additive. Background technique [0002] With the intensification of global warming and the improvement of breeding intensification, production cattle are being challenged by a severe thermal environment, and there are adverse stress reactions such as decreased appetite, reduced feed intake, decreased production capacity, and weakened disease resistance. In order to increase the economic benefits of milk and beef cattle breeding, early weaning technology has been widely used at home and abroad, but early weaning also brings calves such as reduced appetite, reduced feed intake, digestive and metabolic disorders, reduced immunity, diarrhea, growth, etc. A series of adverse stress reactions such as slowness and even death. Therefore, how to overcome adverse stress reactions such as heat stress in production cat...
