Abstract

The invention provides a feed additive and a preparation method thereof. The feed additive comprises a core material and a coating material for wrapping the surface of the core material, wherein the coating material comprises acrylamide resin, cellulose acetate, and palm fatty powder, and by regulating and controlling the mass ratio of the acrylamide resin to cellulose acetate to palmitic fatty, the core material of polyunsaturated fatty acids and/or polyunsaturated fatty acid ester can be protected effectively, degradation of the polyunsaturated fatty acids and/or polyunsaturated fatty acid ester in a rumen is avoided, instead, the polyunsaturated fatty acids and/or polyunsaturated fatty acid ester enters a small intestine and then is absorbed, so that the effective passing rate of the polyunsaturated fatty acids and/or polyunsaturated fatty acid ester in the lumen and the content of the polyunsaturated fatty acids and/or polyunsaturated fatty acid ester in dairy products are finallyimproved. In addition, the palm fatty powder in the additive provided by the invention and polyunsaturated fatty acid are subjected to emulsification, and it is beneficial for intestinal absorption, and the health of the dairy cow and the milk yield can be improved.

Description

technical field [0001] The invention belongs to the technical field of nutritional and functional feed additives for ruminants, in particular to a feed additive and a preparation method thereof, in particular to a polyunsaturated fatty acid additive for dairy cow feed and a preparation method thereof. Background technique [0002] As a major livestock product, milk provides humans with high-quality protein, essential fatty acids, minerals, vitamins and other nutrients. With the improvement of living standards, people's demand for livestock products has been upgraded from quantity demand to quality demand, especially the demand for milk to promote health has been continuously strengthened. Among the many nutritional components of milk, polyunsaturated fatty acids have attracted much attention. [0003] Polyunsaturated fatty acids (PUFA) refer to straight-chain fatty acids containing two or more double bonds and a carbon chain length of 18-22 carbon atoms, usually divided int...
