In this study, we evaluated the incidence of metritis and its effect on the reproductive performance of sows. The results show that sows infected with metritis have a change in clinical index: pain response, increased body temperature, respiratory rate increased, inflammatory fluid secreted a lot, typical color and stench . The rate of pigs suffering from metritis is quite high, average is 31.46%. The incidence of the disease decreases gradually from the first parity account for 40% and d ecreased in parities 2 3 and 4, respectively 30.76; 27.27; 18.18%, from the 5th parity, the rate of metritis tends to increase gradually, from 20% to 30% (age 6), 40% (age 7) and 44.44% (over 7). Uterine infection can be cured with antibiotics, Hitamox L.A combined with Oxytocin has a faster treatment time than Mycocin 100 combined with Oxytocin. Inflammation of the uterus has a great influence on the reproductive performance of sows. The cured herds had a longer period of re-estrus after weaning, the estrus rate and The percentage of sows conceiving is lower than that of normal sows
