Rumen protection amino acid and preparing method

Abstract

The invention relates to a process for rumen-protected amino acids wherein crystalline amino acids is taken as materials, physical cover technique adopted, mixing amino acids and stomach and enteric soluble materials to prepare into nucleus , thereof to be covered with a thin film, again spraying a layer of protective material, then drying in low temperature to obtain rumen-protected amino acids.

Description

technical field [0001] The invention relates to a rumen-passing protected amino acid (RPAA) and a preparation method thereof. Background technique [0002] People's interest in ruminant-limiting amino acids can be traced back to the early 1970s. In the abomasum and intestinal perfusion tests and intravenous infusion tests, it was found that the absorbable methionine in ruminant feed was not always ideal (Chalupa, 1975; Schwab, 1995 ), and pointed out that methionine is the first limiting amino acid for hair production and weight gain for finishing cattle and lactating cattle. Later, it was found that lysine is the second limiting amino acid for lambs, and lysine is also the first or second limiting amino acid for breeding cattle and lactating cows. At the same time, with the development of ruminant breeding industry, operators and livestock workers are faced with the arduous task of increasing animal production capacity, improving the quality of livestock products, reducing...

Problems solved by technology

In China, since the 1980s, a large amount of research work has been carried out around the amino acid nutrition of ruminants, and a good foundation has been established in theories such as the mechanism of action and effects (Feng Yanglian 1993, Lu Dexun, 1991). However, the protection of ruminant amino acids There are very few researches on technology and production, and there is a certain gap from industrialized production, which cannot meet the growing demand and urgently needs to be researched
