Feed additive capable of reducing somatic cell account of dairy cow and preparation method thereof

Abstract

The invention discloses a feed additive capable of reducing somatic cell account of dairy cow. The feed additive capable of reducing somatic cell account of dairy cow comprises the following ingredients in parts by weight: 20 parts of honeysuckle flower extract and eucommia bark extract, 15 parts of small peptides for feed, 50 parts of yeast for feed and 30 parts of lactic acid bacteria for feed. Usage method of the feed additive capable of reducing somatic cell account of dairy cow comprises the following steps: fully mixing 20 parts of honeysuckle flower extract and eucommia bark extract, 15 parts of small peptides for feed, 50 parts of yeast for feed and 30 parts of lactic acid bacteria for feed; sieving the mixture by a 80-mesh sieve according to feed grades; uniformly mixing the sieved mixture; and adding the sieved mixture into compound feeds in three gradient addition amounts, including 0.01%, 0.03% and 0.05%. The feed additive for improving dairy cow breast health by reducing somatic cell accounts of the dairy cows provided by the invention has obvious effects of preventing and treating mastitis of the dairy cows. Thus, the feed additive is capable of promoting breast health of the dairy cows and improving qualities of the milk products.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and particularly relates to a feed additive for reducing the somatic cell count of dairy cows and a preparation method thereof. Background technique [0002] Somatic cell count (SCC) is an important indicator reflecting the udder health of an individual dairy cow, which determines the output, composition, quality and storage time of milk. Subclinical mastitis reduces milk production by 10% to 20%, fat, protein, and dry matter content all decrease, and the total number of bacteria and somatic cell count increase significantly. When the breast tissue is infected by germs, the body's immune system will secrete a large number of immune cells to clear the infection, resulting in a significant increase in the number of somatic cells in raw milk. Further, it will lead to certain changes in the output and composition of raw milk. The health of dairy cows is not only closely related to milk prod...

Problems solved by technology

[0004] The purpose of the present invention is to provide a feed additive for reducing the number of somatic cells in dairy cows, aiming to solve the problem that the treatment of mastitis mainly relies on antibiotic therapy for a long time. However, with the extensive use of antibiotics, the negative problems of drug residues and bacterial resistance serious
