Description

Composite cow nipple medicated bath liquid and preparation method thereof

Technical Field

The invention belongs to the technical field of prevention and treatment of cow mastitis, and particularly relates to a composite cow nipple medicated bath liquid and a preparation method thereof.

Background

Cow mastitis is caused by infection of various pathogenic microorganisms, and is one of the most common diseases causing the greatest economic loss in cow production. Worldwide losses due to cow mastitis amount to $ 350 billion annually. When people eat the milk produced by dairy cows with mastitis, the symptoms of diarrhea, vomiting, fever and the like can be caused. Therefore, the method has great significance in production practice for strengthening the prevention and treatment of cow mastitis, especially recessive mastitis.

The symptoms of cow mastitis are inflammation of parenchyma and mesenchyme of breasts. The etiology is mostly caused by mechanical stimulation, invasion of pathogenic microorganisms and chemical and physical injuries. More than 150 kinds of pathogenic microorganisms of cow mastitis are known at present, including cocci, bacilli, mycoplasma, fungi, yeasts, viruses and the like. Most of the bacteria are caused by bacterial infection, mainly caused by gram-positive bacteria (such as streptococcus agalactiae and staphylococcus aureus), and gram-negative bacteria (escherichia coli) are common in large-scale culture. The commonly adopted prevention and treatment measures include the effects of improving milking sanitation, creating good sanitary conditions, enhancing the immunity of the dairy cows and the like. The achievement of milking hygiene is the most important aspect, and the medicated bath on the teats of the cows before and after milking is an effective method at present.

The traditional medicinal bath liquid has a plurality of types, but certain damage and stimulation to the breast skin and internal tissues of the dairy cow caused by some disinfectants (such as alcohol and hydrogen peroxide) are eliminated by the market, and the currently applied dairy cow nipple agent is mainly iodine disinfectants. The disinfectant is generally composed of polyvinylpyrrolidone, iodine, potassium iodide, glycerol, ethanol and a thickening agent, and can form a protective film on the nipples of the dairy cows to protect the nipples. But has the defects that (1) the glycerin moisture-keeping effect is easily influenced by the ambient humidity, and the effect of keeping water molecules is reduced when the ambient relative humidity is too low. In addition, the aim of high-efficiency moisture preservation is difficult to achieve due to the mechanism of the milk cow nipple skin moisturizing cream, the long-time moisture preservation effect is not ideal, and the milk cow nipple skin can be cracked; (2) the iodine preparation has slight transient irritation to topical mucous membrane of cow papilla wound, and is unstable under illumination and high temperature, and has transient bactericidal effect.
