Film-forming agent capable of preventing cow mastitis and preparation method thereof

Abstract

The invention relates to a film-forming agent capable of preventing cow mastitis, comprising by weight, 0.6 o 1.2 parts of povidone iodine, 1 to 2 parts of tween 80, 0.2 to 0.6 part of glycerine, 8 to 12 parts of PVA (polyvinyl acetate), and 100 parts of distilled water. The invention further relates to a preparation method of the film-forming agent. The preparation method includes the steps of sterilizing with distilled water, temperature adjusting, adding of the povidone iodine, glycerine, tween 80 and PVA, pH adjusting and the like. The components and production process are further simplified, thus the film forming speed is high and breathability is good, the film-forming agent is nonirritating to skin mucosa. Especially, the film-forming agent and the preparation method thereof have the advantages such as high antibacterial activity, short film-forming time, easiness of eluting or stripping, agent stability, convenience of use and the like.

Description

technical field [0001] The invention belongs to the technical field of cow mastitis prevention, and in particular relates to a film-forming agent for preventing cow mastitis and a preparation method thereof. Background technique [0002] Cow mastitis is a series of udder inflammations caused by mechanical damage (such as excessive milking vacuum pressure or udder abrasions in pens, etc.) and pathogen invasion. In mild cases, it will lead to changes in milk quality and waste milk, and in severe cases, it will cause redness, swelling and heat in the breasts. Pain, and may develop into breast hyperplasia, and even nipple necrosis. The incidence of dairy cow mastitis is high, which can be divided into clinical type and recessive mastitis according to whether the clinical symptoms are obvious or not. Among them, the incidence of recessive mastitis can be as high as 30%, which seriously affects the health of dairy cows and breeding benefits. The main cause of recessive mastitis i...

Problems solved by technology

[0003] At present, most of the disinfectants used for post-milking disinfection of cows are liquid disinfectants, that is, dipping the teats after milking. This method is simple and fast, but the liquid will drip quickly under the influence of gravity, and the effect is short-term, so it cannot play a disinfection role for a long time , thus not protecting the teat ducts from microbial invasion
