Transrectal ultrasound detection of sheep using B-ultrasound has been recommended as a simple, rapid, and practical method for early pregnancy diagnosis in sheep. The use of B-ultrasound for sheep provides a simple, fast, accurate, and non-invasive method for diagnosing pregnancy in sheep farms. Sheep pregnancy (with no echogenic intrauterine fluid) can be diagnosed by transrectal ultrasound (5 MHz) as early as the 17th to 19th day of pregnancy, while the embryo itself can be imaged between the 21st and 34th day of pregnancy. During transrectal scanning using a 5 MHz transducer, early pregnancy can be identified by the presence of echoless fluid in the uterus from day 17 to day 19, while the embryo itself and placenta can be seen from day 26 to day 26. 28 years of pregnancy. The age and breed of the ewe, as well as the experience of the operator, are the main factors causing these variable outcomes.

Early detection of pregnancy and determination of the number of fetuses are economically beneficial for sheep producers. Pregnant ewes can be sold to reduce feed costs, while pregnant lambs can be sold at a price higher than adult ewes. Dividing the flock into pregnant and non pregnant ewes may reduce reproductive and production losses caused by miscarriage, stillbirth, and weak sheep production. The prediction of the number of fetuses will allow for appropriate nutritional management of ewes in late pregnancy, thereby preventing pregnancy toxemia, minimizing prenatal feeding costs, optimizing birth weight, weaning weight, and lamb survival rates, and reducing the incidence of difficult labor. The methods used for pregnancy diagnosis should be simple, accurate, fast, inexpensive, practical, and safe for both the operator and the animal. The method of pregnancy diagnosis depends on the visualization of the pregnant body or the measurement of its secreted products in maternal blood or milk, which is the most accurate and specific pregnancy method. The ultrasound examination of sheep using B-ultrasound has been widely accepted in the veterinary field for diagnosing pregnancy. Transrectal ultrasound examination is recommended as a simple, rapid, and practical method for early pregnancy diagnosis in Mianyang.
