Symptoms and comprehensive prevention and treatment of porcine endometritis
When sows are in breeding, artificial insemination, delivery, midwifery and abortion, if they do not pay attention to hygiene or disinfection is not strict, bacteria will be brought into the uterus, resulting in reproductive infection of sows, including Escherichia coli, Corynebacterium, Streptococcus, Staphylococcus, Pseudomonas aeruginosa, Proteus and so on, leading to endometritis. During delivery, the operation of the birth canal or part of the placenta remains in the uterus, which can also cause endometritis. The floor of the barracks is not sanitary, or when sows are active in the playground with sewage, bacteria can also enter the uterus through the vagina to cause inflammation.
When endometritis occurs, dark red or brown secretions flow from the vulva of the sick beaver and stick around the vulva, sometimes smelly. Sows urinate with a large amount of white or brown liquid more than ten days after birth. The disease makes the uterus unsuitable for sperm, eggs and embryos. As a result, sows cannot get pregnant. In chronic endometritis, the appetite or spirit of diseased pigs is normal; in acute endometritis, the appetite of diseased pigs is decreased or abolished, and the body temperature is 39 5 ℃-42 ℃.
Prostaglandin F2a (PGF2a) was injected 12 days after estrus and PGF2a was injected 12 days after estrus was observed. In estrus 3 days after each injection of PGF2a, first intramuscular injection of 20-40IU oxytocin to promote uterine contraction and excretion of uterine contents, then use disinfectant to clean and disinfect the vagina, store the sterilized vas deferens into the cervix, and inject antibacterial and anti-inflammatory drugs into the uterus. If treated with penicillin, it can be cured. If the disease occurs during postpartum lactation, it is not necessary to inject PGF2a. If a rise in body temperature occurs, antibiotics should be injected intravenously or intramuscularly, plus 10 Mel 25 ml of aminopyrine, twice a day for 3 consecutive days. After treatment, sows can be mated when they are in estrus.
The preventive measures are to keep the pig house clean and dry, strictly disinfect during mating and midwifery, and insert antibiotic capsules into the uterine cavity after midwifery.

How to give a pig an injection
Injecting pigs is the main method to prevent and treat pig diseases. Several injection methods are usually used, such as intramuscular injection, subcutaneous injection, intravenous injection, intraperitoneal injection and so on. Intramuscular injection is rich in blood vessels, and the injected solution is absorbed quickly. in addition, the distribution of sensory nerves in muscle is less, and the pain caused by intramuscular injection is less, so it is the most commonly used method of injection. The injection site is generally chosen in the muscular buttocks or neck. When injecting, first shearing, disinfecting, holding the syringe in the right hand, piercing the needle vertically. The depth can be determined according to the size of the pig.
