Composition and application thereof in preventing and treating recessive mastitis of dairy cows

Abstract

The invention relates to a composition, in particular to a composition and an application thereof in preventing and treating recessive mastitis of dairy cows. The composition comprises isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C, wherein the mass ratio of the isochlorogenic acid A to the isochlorogenic acid B to the isochlorogenic acid C is (8-16): (8-12): (20-35). In the application process, the composition provided by the invention can efficiently reduce the morbidity of the recessive mastitis, improve the physique of dairy cows and reduce the milk conductivity. Besides, the isochlorogenic acid A, the isochlorogenic acid B and the isochlorogenic acid C can be extracted from plants, are rich in source and easy to obtain, have no residues after being compounded, and provide more choices for antibiotic-free culture and green culture.

Description

technical field [0001] The invention relates to a composition, in particular to a composition and its application in the prevention and treatment of milk cow recessive mastitis. Background technique [0002] Bovine mastitis (Bovine mastitis) is an inflammatory change of mammary glands that is stimulated by physical, chemical and microbial stimulation. It is a common and frequently occurring disease in dairy cows. one of the diseases. Dairy cow mastitis has the characteristics of wide occurrence range and high incidence rate. Cow mastitis can be divided into clinical mastitis and subclinical mastitis according to the presence or absence of clinical symptoms. Recessive mastitis in dairy cows is often ignored because of its inconspicuous clinical symptoms and no visible changes in the milk. It will not only lead to a decrease in milk production and quality, but may also be transmitted to other dairy cows, leading to the spread of the disease. When mastitis occurs in dairy co...

Problems solved by technology

[0003]Currently, antibiotics are mainly used to prevent mastitis in cows clinically. However, if antibiotics are used to prevent latent mastitis, the milk during the medication period and within 5 days of stopping the medication cannot be sold , which will affect its economic efficiency

For the prevention and treatment of mastitis, most of the broad-spectrum antibiotics are given by antibiotics or combined drugs. However, the long-term use of antibiotics has caused pathogenic bacteria to increase their resistance to antibiotics, often resulting in prolongation of the prevention and treatment cycle and increase in dosage. Serious Sometimes, the prevention and treatment are even ineffective; and the use of antibiotics often has food safety problems such as residues
