[0024] 1. Purpose of the test:
[0025] Cow recessive mastitis is a serious problem that plagues the production of dairy cows and brings great losses to the production of dairy cows. Nowadays, antibiotics are mainly used for treatment in production, which brings hidden dangers to the health of dairy cows and affects the safety of raw milk. In "antibiotic-free" With the growing demand for animal products, biological antimicrobial peptide products are used to treat latent mastitis in dairy cows to achieve the effect of preventing mastitis. In addition, organic selenium and vitamin E are supplemented to enhance the immunity of dairy cows.

Abstract
The invention relates to the field of feed additives, in particular to a feed additive for treating dairy cattle recessive mastitis. According to the feed additive for treating dairy cattle recessive mastitis provided by the invention, the feed additive comprises the following ingredients in percentage by mass: 85 percent to 91 percent of biological agent antimicrobial peptides, 8 percent to 14 percent of organic selenium and 0.3 percent to 1.2 percent of vitamin E. The invention provides a dairy cattle functional feed additive recipe composition by aiming at solving a series of problems of immunity and production performance reduction and the like caused by recessive mastitis of generally existing in dairy cattle in the prior art. The feed additive has the advantages that the biological agent antimicrobial peptides are utilized for treating the dairy cattle recessive mastitis, the traditional antibiotic treatment method is replaced, the harm to the health of the dairy cattle caused by the antibiotics and the residue of the antibiotics in the milk are reduced, the organic selenium and the vitamin E are added, and the collective immunity of dairy cattle is enhanced.
Description
technical field [0001] The invention relates to the field of feed additives, in particular, the invention relates to a feed additive for treating dairy cow recessive mastitis. Background technique [0002] Cow mastitis is one of the common diseases that harm dairy cows. There are about 220 million dairy cows in the world, and about 1 / 3 of them suffer from various types of mastitis, which causes a loss of 30 billion US dollars in the world every year. Milk losses in the region amount to 300,000 tonnes per year. According to reports, the annual loss caused by cow mastitis in the United States can reach 2 billion US dollars, Germany's annual loss is about 460 million marks, and my country's annual loss exceeds 316 million yuan. According to statistics, the positive rate of mastitis in dairy cows in my country is 46.4% to 85.7%, and the positive rate in the udder area is 28% to 59%. my country's Beijing, Shanghai, Tianjin, Guangzhou, Xi'an, Lanzhou and other cities survey resu...
