Embodiment 1

[0062] A rumen-passing vitamin A, its composition is as follows: ball core, is made up of vitamin A and PEG6000; The weight ratio of vitamin A and PEG6000 is 1:0.5; The first coating, covers described ball core; Wherein, said first The coating consists of glyceryl monostearate, solid paraffin, calcium hydrogen phosphate, and calcium phosphate in a weight ratio of 10:25:10:10; the weight ratio of the ball core to the first coating is 45:55.

[0063] In the rumen-passed vitamin A described in this embodiment, by weight percentage: the content of the ball core is 45%, and the content of the first coating is 55%.

[0064] The present embodiment also provides the preparation method of the rumen-passed vitamin A, comprising:

[0065] Put vitamin A into a pulverizer, pass through a 120-mesh sieve, mix the obtained product with PEG6000 at a weight ratio of 1:0.5, heat to about 70°C to melt and then cool to obtain a solid dispersion as a pellet core.

[0066] Glyceryl monostearate and...

Embodiment 2

[0070] A rumen-passing vitamin A, the only difference from Example 1 is that glycerol monostearate is replaced by an equivalent amount of stearic acid. The preparation method refers to Example 1.

Embodiment 3

[0072] A rumen-passed vitamin A, the only difference from Example 1 is that PEG6000 is replaced by an equivalent amount of PEG4000.

Abstract

The invention provides rumen vitamin A. Raw materials of the rumen vitamin A mainly comprise vitamin A, polyethylene glycol, binding agents and excipients. The degradation rate of the provided novel rumen vitamin A in rumens is low. By means of the rumen vitamin A, the body immunity and the reproductive performance of dairy cows can be improved, so that income of a pasture is greatly increased.

Description

technical field [0001] The invention relates to rumen-passed vitamins, in particular to rumen-passed vitamin A and its preparation method and application. Background technique [0002] Vitamin A is an essential fat-soluble vitamin for dairy cows and is necessary to maintain the normal metabolism of animals. Vitamin A plays an important role in maintaining normal visual function, cell differentiation, bone growth, animal reproduction and body immunity. Microorganisms in the rumen of ruminants cannot synthesize vitamin A, and therefore, exogenous supplementation is required in dairy cow diets. According to reports, the stability of vitamin A in the rumen is poor, especially when the degradation rate is high under the condition of high concentrate diet. In order to alleviate the degradation of vitamin A in the rumen and improve the utilization effect of vitamin A, it is very necessary to protect it in the rumen. Contents of the invention [0003] The embodiment of the pres...
