Problems solved by technology

At present, the main problems of using fatty (acid) packaging materials are that the process used is unreasonable, the content of methionine is low, the coating is uneven and incomplete, so the effect of passing through the rumen is poor, and the physical form of the product is not good. Ideal, the particles are large and uneven, neither industrial production nor convenient to use in production
The methionine treated with polymer as the packaging material has a good rumen passing effect, and the product has a high methionine content, but the cost of the packaging material is high and the process is complicated, so the price of the produced product is high and the economic feasibility is poor; in addition, Some polymers themselves have no nutritional function and are not easily absorbed and utilized by animals

Embodiment 1

[0038] Example 1. Preparation of Rumen Protected Methionine 1

[0039] 1. Preparation of Methionine Granules

[0040] Methionine, dextrin and microcrystalline cellulose are mixed in proportion to obtain a mixture. In the mixture, the mass proportion of methionine is 94.4%, the mass proportion of dextrin is 1.1%, and the mass proportion of microcrystalline cellulose is It is 4.5%, and then the mixture is prepared with water into a state that can be granulated, and the granules are prepared with a granulator, and then shot with a spherical shot blasting machine to obtain methionine granules.

[0041] 2. Drying of methionine particles

[0042] Put the methionine granules prepared in step 1 into a fluidized granulating and coating machine for drying. The heating temperature of the equipment is 80℃, the induced air frequency is 35Hz, the rotation speed is 45Hz, and the drying is 30 minutes. It is then sieved with 30 mesh and 40 mesh sieves to obtain dry methionine particles with a partic...

Abstract

The invention discloses rumen protected methionine and a production method thereof. The rumen protected methionine consists of a core and a shell, wherein the shell is rumen pass fat powder, the active ingredient of the core is methionine; and the mass ratio of the methionine to the rumen pass fat powder is (35-65):(30-60). Animal experiments prove that: the rumen protected methionine has good stability and high small intestine digestibility, can obviously improve the nitrogen metabolism of milk cows, can improve the milk yield and the milk quality of the milk cows during the production, and obtain considerable economic benefit.

Description

Technical field [0001] The invention relates to rumen protected methionine and its production method. Background technique [0002] Methionine is an essential amino acid and the first limiting amino acid for milk production in dairy cows. Generally, the content of methionine in conventional dairy cow feed is generally low, resulting in an imbalance or serious shortage of amino acids in the dairy cow’s diet, resulting in low feed protein utilization and decreased milk protein content. Add ordinary methionine directly to the dairy cow's diet. Due to the action of rumen microorganisms, most of the added methionine is degraded in the rumen and cannot reach the small intestine. This not only fails to achieve the effect of adding methionine, but also causes a waste of methionine. The only way to solve the problem is to protect the added amino acid from the rumen so that it will not be degraded in the rumen, and will directly reach the small intestine to be absorbed and utilized. Add...
