Problems solved by technology

[0004] The present invention aims at supplementing common choline additives in dairy cow rations, which not only increases the feed cost of dairy cows, but also cannot meet the choline supply requirements of dairy cows at peak lactation period, especially high-yield dairy cows, because it is easily degraded by rumen microorganisms. One shortcoming, provide a kind of choline passing rumen microcapsule and preparation method thereof

Abstract

The invention discloses chlorine rumen-protected microcapsule additive and a preparation method thereof. The additive comprises a kernel and a surface layer which wraps the kernel; and the kernel comprises the ingredients of chlorine-based mixture, wherein the chlorine-based mixture comprises the following components by weight percent of 83 to 98.9 percent of choline chloride adopting silicon dioxide as a carrier, 1 to 10 percent of No.4 polyacrylic resin and 0.1 to 10 percent of hypromellose. Due to the adoption of the chlorine rumen-protected microcapsule additive and the preparation methodthereof, deliquesce of the choline chloride in the air can be reduced, damage of the choline chloride on other ingredients in the feed can be reduced, and the storage and application of the choline chloride can be facilitated. When the additive is added into feed for dairy cow, the productivity and health of the dairy cow can be improved, the utilization efficiency of the feed can be improved, environmental pollution caused by excretion of the dairy cow during the breeding process can be reduced, the rearing cost of the dairy cow can be reduced, and an important significance on promoting the sustainable development of the agricultural economy in China and the society progress can be realized.

Description

technical field [0001] The invention relates to an additive and a preparation method thereof, in particular to a choline passing rumen microcapsule additive and a preparation method thereof, belonging to the field of feed additives. Background technique [0002] my country is a large agricultural country in the world. The dairy industry in animal husbandry has developed rapidly, and the number of dairy cows has continued to increase. Efficient feeding methods and levels affect the milk production of dairy cows, as well as their lactation potential and health. Adding rumen-passed choline to ruminant diets can improve their performance. In body metabolism, choline and methionine are the two main methyl donors, and the methyl group provided by choline (through betaine) can be combined with homocysteine ​​to form methionine. Adding choline to the diet can save methionine, make more methionine be used for protein synthesis, meet the protein demand of ruminants, and improve prod...
