Description

technical field [0001] The invention relates to a compound iodized chitosan coating agent for preventing and treating bovine and sheep mastitis and a preparation method thereof, belonging to the technical field of veterinary medicine. Background technique [0002] Mastitis is one of the common diseases of cattle and sheep, which is very harmful to livestock production; the infection route of mastitis is usually through the nipple orifice invasion or through blood, lymphatic infection, often caused by unskilled milking techniques, poor milking clean, unclean breasts, and trauma to breasts and nipples caused by bacterial infection. Mastitis will affect the health of cattle and sheep, and reduce economic income; there are about 220 million dairy cows in the world at present, and about 1 / 3 of them suffer from various types of mastitis. The loss is as high as 300 billion yuan. [0003] Pathogen infection is the main cause of mastitis in dairy cows, and the main pathogenic bacte...
