Mild endometritis in cows has a normal estrus cycle, with slightly cloudy and unclear secretions. When cows are observed by B-ultrasound, there are few strong echoes in the uterus. Penicillin 6.4 million units and streptomycin 1 million units can be used, diluted with 50-150 milliliters of physiological saline, and injected into the uterus once. Cows can be observed by B-ultrasound for timely insemination after estrus. Generally, it can be cured once.

Cows with moderate endometritis have normal estrus, and there are many flocculent substances in their secretions. Most of them have a history of placenta arrest, which is caused by contamination of the uterus during delivery. When cows are observed by ultrasound, there are many strong echoes in the uterus. For treatment, any one of the following flushing solutions can be used: 1% -10% saline solution, 1% baking soda solution, 0.02% -0.05% potassium permanganate solution, 0.1% rivanol solution, and 0.05% furazone solution. The temperature should be between 40-45 ℃, and the dosage is generally between 500-1000 milliliters. It is recommended to inject the solution into the uterus once and fill it moderately. Intrauterine injection of 15-25 milligrams of estradiol increases uterine contractions to eliminate contents. 24-48 hours later, 1-3 doses of Gongdekang suspension oil are injected into the uterus. After treatment, cattle should be examined by B-ultrasound before mating.

Severe endometritis has an abnormal estrous cycle, with more lochia in the secretions, a strong fishy odor, and a flushed vaginal mucosa. Cattle undergo ultrasound combined with rectal examination for uterine wall thickening, accompanied by elevated body temperature and systemic symptoms. Treatment: First, drain the accumulated water or pus in the uterus, then rinse the uterus once a day or every other day until transparent liquid is discharged. Use B-ultrasound to observe that there is no more fluid accumulation in the uterus. Alternatively, self prepared antibiotics, furacilin, sulfonamide or other disinfectants can be made into water, oil, water emulsion oil and injected into the uterus, with a dosage of 20-40 milliliters. Inject an appropriate amount of air to ensure that the medication fully contacts the uterine mucosa. If there are systemic symptoms, antibiotics and sulfonamides should be used for systemic treatment.
