Embodiment 1

[0038] A kind of rumen-passed histidine, which consists of coating and core. The coating is rumen-passed fat powder, and the active ingredient of the core is histidine; the core is composed of the active ingredient histidine The granule that acid and auxiliary material prepare, and described auxiliary material is calcium stearate (the first auxiliary material) and starch, dextrin, sodium carboxymethyl cellulose; The mass ratio of active ingredient histidine and described auxiliary material is 50:50 , the mass ratio of calcium stearate, starch, dextrin, and sodium carboxymethylcellulose in the adjuvant is 1.4:12.5:11:0.1, and the mass ratio of the core-coating to the coating is 50:50.

[0039] This embodiment also provides a method for preparing the above-mentioned rumen-passed histidine, comprising the following steps:

[0040] 1) Histidine and auxiliary materials calcium stearate, starch, dextrin, and sodium carboxymethylcellulose are mixed in proportion to obtain a mixture. ...

Embodiment 2

[0047] A kind of rumen-passing histidine, the only difference from Example 1 is: calcium stearate is replaced by an equivalent amount of silicon dioxide. The preparation method refers to Example 1.

Embodiment 3

[0049] A rumen-passing histidine, the only difference from Example 1 is that the mass ratio of the core coating to the coating is 55:45. The preparation method refers to Example 1.

Abstract

The invention relates to novel bypass histidine as well as a preparation method and application thereof. The novel bypass histidine consists of two parts of coatings and coated cores, wherein the coatings are made from bypass fatty powder; the coated cores are granules prepared from an active component namely histidine and auxiliary materials; and the auxiliary materials consist of first auxiliarymaterials and second auxiliary materials, wherein the first auxiliary materials are calcium stearate or silicon dioxide, and the second auxiliary materials consist of starch, dextrin and sodium carboxymethyl cellulose. According to the novel bypass histidine disclosed by the invention, the milk yield of cows can be increased, the ration protein can be saved, and the grain of grazing lands can begreatly increased.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a novel rumen-passing histidine and its preparation method and application. Background technique [0002] In recent years, studies have found that adding histidine to diets containing low protein can significantly increase milk production; Ratio, significantly improve the milk production and production performance of dairy cows. A recent study conducted at Penn State University, where lactating cows are typically fed diets based on North American feed ingredients (corn silage, alfalfa semi-dried silage, corn grain, etc.), indicated that histidine is a limiting amino acid. [0003] In 2015, my country proposed a major reform policy of "grain to feed", focusing on adjusting the corn planting structure and guiding the planting of whole plant silage corn. Corn silage with low histidine content will be used as the main source of roughage for ruminants. Secondly,...
