Prevention and treatment of endometritis in infertile cows caused by endometritis

Endometritis is one of the important causes of infertility in dairy cows. Endometritis in dairy cows is closely related to external environment, feeding management, self-metabolism, nutrition and other reasons. When cows are in an environment where microbes multiply and their resistance decreases, endometritis is more likely to occur. Therefore, in line with the principle of "prevention first, prevention is more important than treatment", comprehensive prevention and treatment of endometritis.

Cow

First, strengthen feeding management: feed forage grass and feed scientifically and rationally, improve the nutrition of dairy cows, and achieve early detection and early treatment, so as not to miss the best treatment period.

Second, do a good job in the hygiene of the cattle farm: pay attention to the hygiene of the site, keep the cowbed, barn and sports ground dry, disinfect regularly, deal with cow dung, stagnant water and sewage in time, and keep the cow body clean and dry.

Third, control prenatal and postpartum infection: establish an independent delivery room and disinfect it regularly. Before delivery, the delivery room and vulva of the cow should be disinfected. When midwifery is needed, the arms and instruments of the midwife should be disinfected. Delivery rooms, beds and cows should be kept clean and strictly disinfected. In 24-48 hours postpartum, antibiotics should be infused into the uterus once to prevent postpartum uterine infection. If the placenta of the cow does not fall 12 hours after delivery, measures such as drug injection should be taken to avoid uterine infection. One week after delivery, attention should be paid to the hygiene of the delivery bed, cow vulva and hindquarters.

4. Avoid mating pollution: 1. Semen diluent, dilution apparatus and insemination gun should be strictly disinfected; semen should be absorbed and diluted under aseptic conditions; during insemination, disinfectant should be used to clean the vulva of dairy cows; when inserting the inseminal device, you should avoid putting dirt on the inseminal device and bringing it into the cow's vagina and uterus. 2. During artificial insemination, the equipment, personnel and dairy cows should be strictly disinfected to avoid reproductive organ infection. During insemination, the insemination gun should slowly pass through the cervical fold to avoid uterine infection caused by damage to the cervix or uterine mucosa of dairy cows.

Fifth, pay attention to postpartum adjustment: postpartum drug adjustment can promote uterine involution and early estrus of dairy cows, postpartum uterine contraction fatigue of dairy cows can be injected with estrogen, vasopressin and so on. It can also be administered with traditional Chinese medicine that can regulate qi and blood, activate blood circulation and remove blood stasis, promote uterine contraction, promote and restore the reproductive function of postpartum dairy cows, such as postpartum Gongkangwang, biochemical decoction, Buzhong Yiqi decoction, Taohong Siwu decoction and so on. Cows with normal delivery should be given postpartum Gongkangwang and other pure traditional Chinese medicine preparations or Qinggong liquid, which are mainly biochemical powder, immediately after delivery. One month after delivery, the involution of the uterus of dairy cows should be checked, and the cows with poor involution should be treated in time. In order to promote early estrus, cows can be fed with traditional Chinese medicine to tonify the kidney and help yang, such as debauchery, estrus powder and so on. Pituitary gland can also be injected to promote gonadal hormone-releasing hormone.
