Uterine inflammation in sows refers to the inflammation of the uterus caused by infection during and after childbirth. The causes include: difficult delivery, inability to place the placenta, uterine prolapse, unclean surgical procedures during childbirth, rough handling, uterine damage, postpartum infections, incomplete disinfection during artificial insemination, pathogenic bacteria in the reproductive organs or semen of boars during natural mating, inflammatory secretions, etc., which can lead to endometritis. Malnutrition of sows. When a person becomes weak and their resistance decreases, non pathogenic bacteria in their reproductive tract can also cause illness.
Clinical symptoms
Clinically, it can be divided into acute and chronic endometritis.
① The systemic symptoms of acute endometritis are obvious. The sow's body temperature rises, the spirit is weak, the appetite decreases or disappears, and it often becomes restless. Especially when the sow first lies down, white mucus or foul smelling dirty reddish brown mucus or purulent secretions flow out of the vagina, which stick to the tail root and have a foul odor. Sometimes sows experience abdominal pain symptoms. Acute uterine inflammation often occurs after childbirth and miscarriage.
② Chronic endometritis is often caused by delayed treatment of acute endometritis. The systemic symptoms of the sick pig are not obvious. Sick pigs may periodically release small amounts of cloudy mucus from the vagina. Sows often delay estrus or have abnormal estrus, and even if they can estrus regularly, they are often infertile.
Preventive measures
1. Preventive measures
1) Before giving birth, sows must clean and disinfect their hindquarters, especially the vulva, anus, and tail. Disinfectants such as 0.1% potassium permanganate solution, neomethoxam, or quaternary ammonium salts should be used.
2) Injecting an appropriate amount of uterine cleansing and anti-inflammatory drugs into the uterus of sows after giving birth and excreting the placenta can effectively prevent the occurrence of uterine inflammation and eliminate postpartum uterine inflammation in sows before it occurs.
2. Drug therapy
The treatment of uterine inflammation in sows should start from two aspects:
1) Injecting drugs such as prostaglandins into sows after childbirth to promote the rapid expulsion of placenta and waste, and eliminate the source of infection.
2) Uterine flushing and disinfection drugs, combined with injection of antibiotics, will have better effects.
3) On the day after delivery, each sow is injected with penicillin or amoxicillin intramuscularly.
4) On the day after delivery, rinse the uterus of the sow with tetracycline solution, wait for 5 hours, and then mix penicillin with physiological saline for intravenous injection once a day for 3 consecutive days.
5) Houttuynia cordata and amoxicillin mixed intramuscular injection, once a day, for 5-7 consecutive days.
6) The treatment of uterine inflammation is time-consuming and should be prevented as early as possible. Pigs that cannot recover for a long time should be immediately eliminated.
