Prevention and treatment of uterine inflammation in sows

Sow hysteritis is sow delivery and postpartum, the uterus is sometimes infected and inflammation occurs. The causes are: dystocia, persistent placenta, prolapse of uterus, unclean operation during midwifery, rough operation, uterine injury, postpartum infection, and incomplete disinfection during artificial insemination, and there are pathogenic bacteria in boar reproductive organs or semen during natural mating. Inflammatory secretions can cause endometritis. Non-pathogenic bacteria in the reproductive tract of sows can also cause disease when they are malnourished, too thin and their resistance decreases.

Manifest symptoms

Sow uterine inflammation can be divided into acute and chronic endometritis.

1. Acute endometritis. Systemic symptoms are obvious, sows have elevated body temperature, lethargy, loss of appetite or abstinence, and often feel responsible, especially when the sows are lying down, white mucus or foul-smelling dirty reddish-brown mucus or purulent secretions flow out of the vagina, and the secretions stick to the root of the tail, smelly and smelly. Sometimes sows have abdominal pain. Acute uterine inflammation mostly occurs after delivery and miscarriage.

2. Chronic endometritis. Most of them are not transformed in time by the treatment of acute endometritis. The systemic symptoms of diseased pigs are not obvious. Diseased pigs may periodically discharge a small amount of turbid mucus from the vagina. Sows often postpone estrus, or abnormal estrus, even if they can have regular estrus, they are often infertile.

Prevention and cure measures

1. Treatment

In the postpartum acute phase, ① should first remove the inflammatory secretions accumulated in the uterus and fully rinse the uterus with 1% saline or 0.02% bromogeramine solution, 0.1% potassium permanganate solution and 0.2% dysentery solution. After washing, all the residual solution will be discharged, until all the derived lotion is transparent. Finally, Gongyanjing 100ml was injected into the uterus.

② systemic therapy can be treated with antibiotics or sulfonamides. Penicillin 40 ~ 800000 IU, streptomycin 1 million IU, intramuscular injection twice a day. When chlortetracycline or oxytetracycline hydrochloride was used, sows were intramuscularly injected with 40mg per kg body weight twice a day, and sulfadiazine sodium was injected intramuscularly or intravenously twice a day.

For pigs with chronic endometritis, penicillin 20 ~ 400000 IU and streptomycin 1 million IU can be injected into the uterus with high pressure sterilized vegetable oil 20mL. And hypodermic injection of vasopressin 200000 ~ 400000 IU to promote uterine contraction and excretion of inflammatory secretion in the cavity.

④ honeysuckle, Coptis chinensis, Rhizoma Anemarrhenae, Phellodendron Phellodendri, Plantago asiatica, Polyporus umbellatus, alisma alisma, licorice 15g each, water fried once.

2. Prevention

To prevent the disease, the pigsty should be kept clean and dry, and the ground can be covered with clean hay when giving birth. When dystocia occurs, midwifery should be careful, arms and appliances should be disinfected. After taking fetus and placenta, use disinfection solution to wash the birth canal and inject antibiotics. Artificial insemination should be operated and disinfected in strict accordance with the rules.
