Abstract

The invention discloses a povidone iodine film coating agent for treating mastitis of dairy cows. The 1000 ml of film coating agent comprises the following materials by weight: 48-52 g of PVP-I (povidone iodine stock solution) with the mass percent concentration of 10%, 18-22 g of CMC (Carboxyl Methyl Cellulose), 1-4 g of polyvinylpyrrolidone with the model number of k13-18 and 0.3-0.7 g of potassium iodate. The povidone iodine film coating agent, prepared by the invention, is good in stability, obviously enhanced in antibacterial effect, improved in milk production of the dairy cows and greatly saved in labor and medicine costs, and good in application effect; and the povidone iodine film coating agent is a film coating agent which is special for treating mastitis of dairy cows, low in cost and high in curative effect. The preparation method of the povidone iodine film coating agent is simple in process, simple and convenient in content determination method, stable in quality, reliable in effect and suitable for extensive dairy farms.

Description

technical field [0001] The invention belongs to the technical field of veterinary drug preparations, and in particular relates to a povidone-iodine coating agent for treating cow mastitis and a preparation method thereof.
