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 methio...

Embodiment 1

[0038] Embodiment 1, preparation of rumen protected methionine 1

[0039] 1. Preparation of Methionine Granules

[0040] Mix methionine, dextrin and microcrystalline cellulose in proportion to obtain a mixture. In this mixture, the mass proportion of methionine is 94.4%, the mass proportion of dextrin is 1.1%, and the mass proportion of microcrystalline cellulose 4.5%, and then adjust the mixture with water to a state that can be granulated, prepare granules with a granulator, and then use a spherical shot blasting machine to shot blast to obtain methionine granules.

[0041] 2. Drying of Methionine Pellets

[0042] Put the methionine granules prepared in step 1 into a fluidized granulation coating machine for drying. The heating temperature of the equipment is 80°C, the induced air frequency is 35Hz, the rotation speed is 45Hz, and the drying time is 30 minutes. Then sieve with 30-mesh and 40-mesh sieves respectively to obtain dry methionine granules with a particle size g...

[0054] Embodiment 3, the preparation of rumen protected methionine 3

[0055] 1. Preparation of Methionine Granules

[0056] Mix methionine, dextrin and microcrystalline cellulose in proportion to obtain a mixture. The mass proportion that methionine accounts for in this mixture is 91.7%, the mass proportion that dextrin accounts for is 1.6%, and the mass proportion that microcrystalline cellulose accounts for is 6.7%, then the mixture is modulated into the state that can be granulated with water, uses Granules are prepared by a granulator, and then shot blasted by a spherical shot blasting machine to obtain methionine granules.

[0057] 2. Drying of Methionine Pellets

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-passing protected methionine and a production method thereof. Background technique [0002] Methionine is an essential amino acid and the first limiting amino acid for milk production of 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 diet of dairy cows, resulting in low feed protein utilization and a decrease in milk protein content. Add ordinary methionine directly to dairy cows' 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 will not only fail to achieve the effect of adding methionine, but also cause waste of methionine. The only way to solve the problem is to carry out rumen protection treatment on the added amino acid, so that it will not be degraded in the rumen, and directly reach the small intestin...
