Treatment: ① systemic treatment, anti-bacterial and anti-inflammatory. Commonly used drugs are penicillin, streptomycin, gentamicin, enrofloxacin, ciprofloxacin and sulfonamides, which are injected intramuscularly for 3 ~ 5 days. The combination of penicillin and streptomycin, or penicillin and neomycin, has better curative effect. ② Local treatment. In the case of chronic mastitis, after the breast is washed and dried, fish fat ointment (or fish fat cod liver oil), camphor ointment and 5% ~ 10% tincture of iodine are selected, and the medicine is applied to the affected skin of the breast, or hot compressed with a wet towel. In addition, the injection of antibiotics into the nipple also has a good effect, that is, the antibiotics are diluted with a small amount of sterilized distilled water and injected directly into the mammary duct. During the medication period, suckling piglets should be artificially breastfed to reduce sow irritation and protect piglets from breast milk infection. In acute mastitis, 500,000 ~ 654.38+00,000 units of penicillin were dissolved in 200 ~ 400 ml of 0.25% procaine solution, and the breast base was annularly closed, 654.38+0 ~ 2 times a day. ③ Chinese medicine treatment. Dandelion 15g, honeysuckle 12g, forsythia suspensa 9g, luffa sponge 15g, medulla tetrapanacis 9g, pangolin 9g and hibiscus 9g are ground into powder, brewed in boiling water, and taken once after warming.
Note: If the abscess is mature, it should be cut and treated surgically as soon as possible.
Prevention: first, strengthen the sanitary management of sow piggery, keep it clean and disinfect it regularly; Second, the sow should lie on its side as far as possible during childbirth, and the midwifery time should be short to prevent suckling piglets from biting their nipples.
