Abstract:

Endometritis is a widespread postpartum reproductive disease in dairy cows,it can lead to prolongation of calving interval,decrease of milk production,increase of elimination rate,abandonment of milk source during treatment,increase of management and treatment cost,and is also one of the important reasons leading to infertility of dairy cows.At present,there are many diagnostic techniques and treatment methods for preventing and treating cow endometritis at home and abroad,including colposcopy,Metricheck device evaluation,uterine cytology examination,antibiotic therapy,traditional Chinese medicine therapy,integrated traditional Chinese and Western medicine therapy,hormone therapy,ozone new therapy and so on.Colposcopy is a visual examination method,which can directly evaluate the vaginal endocrine characteristics of dairy cows to determine the severity of endometritis.The Metricheck device is designed to evaluate the endometritis and reproductive performance of postpartum dairy cows according to the content and characteristics of vaginal endocrine products.In cytological examination of uterus,the ratio of endometrial cells to neutrophils (PMN) was determined by uterine cell brushing,lavage or biopsy,and the optimal threshold of PMN was set for diagnosis of endometritis in dairy cows at different postpartum stages.Antibiotic therapy can treat cow endometritis through intrauterine infusion,subcutaneous injection and intravenous injection of antibiotics,the treatment cost is low and the effect is quick and it is the most commonly used treatment for cow clinical endometritis at present.Chinese medicine therapy screens different components of Chinese medicine compound preparation,through regulating the body immune system of dairy cows,improves blood circulation in uterus,inhibits the reproduction of pathogenic bacteria,and promotes the recovery of normal physiological function of uterus.The combination of traditional Chinese medicine and Western medicine has the advantages of dialectical treatment of traditional Chinese medicine and the characteristics of quick effect of Western medicine,it has wide application value in clinical treatment of dairy cow endometritis.In hormone therapy,prostaglandin can induce luteal lysis,eliminate progesterone production and immunosuppression,stimulate uterine involution,and reduce the risk of long-term uterine infection and inflammation in postpartum dairy cows.Ozone new therapy is to make ozone into foam preparations,oil products and other products through intrauterine perfusion to kill pathogens.These diagnostic and therapeutic techniques have achieved different results in the treatment of endometritis in dairy cows,and have a good guiding role in evaluating reproductive performance and production performance of postpartum dairy cows.This article introduced the research progress of the application of these diagnostic and therapeutic techniques in dairy cow endometritis,so as to provide reference for the prevention and treatment of the disease.
