Ewe metritis is inflammation of the uterine mucosa and is the most common female reproductive organ disease. By observing the state of the ewe's uterus using a sheep B-ultrasound machine, it was found that after sheep suffer from metritis, the ewe often has abnormal estrus, or the ewe is in normal oestrus but is not easy to conceive. Even if the ewe is pregnant, it is easy to miscarry, so this disease is also Important causes of infertility in ewes. If you want to diagnose this disease, sheep B-ultrasound plays a big role.

      First of all, the main symptoms are the acute type. The sick sheep often bend their waists, strain, and urinate, and discharge sticky or mucopurulent secretions from the vulva from time to time. In severe cases, the secretions are dirty red or brown with a smell, and the sick sheep lies down. When the vaginal discharge occurs, there is a large amount of discharge, and the area around the vulva, the root of the tail, and the hind limbs are often contaminated with exudates and crusted. The body temperature of the sick sheep increased slightly, the spirit was depressed, the appetite and milk production were significantly reduced, rumination was reduced or stopped, and there was mild suffocation, sometimes grinding the teeth, and kicking the abdomen with the hind legs. In severe cases, the sick sheep will be in a coma. If the treatment is not timely, it may cause cystitis, uterine necrosis, etc., and even death. The vagina and vestibule are inflamed, the external opening of the cervix is swollen and congested, and slightly opened. Sometimes, mucopurulent secretions are discharged from the cervix. When diagnosing such diseases by sheep B-ultrasound, irregular echo structures can be seen in the uterine cavity on the sheep B-ultrasound, sometimes large areas of liquid dark areas.

Chronic type, mostly due to the transformation of acute inflammation. Generally, there are no obvious systemic symptoms. Sometimes the body temperature of sick sheep is slightly increased, the appetite and lactation are slightly reduced, and transparent, turbid or mixed with purulent flocculent secretions are discharged from the vulva. The external opening of the cervix of sick sheep is swollen, congested, and accompanied by mucus. The estrus is regular or stopped, and repeated mating is infertile. The cervix is completely closed, there is no discharge on the surface, and sometimes it can develop into uterine hydrops. Sick sheep often do not estrus for a long time. A large amount of low-echo thick juice can be seen in the uterine cavity on sheep B-ultrasound, sometimes large areas of liquid dark areas.
