Research work was carried out in 3 farms. The determination of pregnancy in animals is carried out using clinical and biophysical studies. The device "Pregnancy diagnosis" was used for the instrumental diagnostic method. Results. The effectiveness of an instrumental diagnostic method has been revealed, which allows to diagnose pregnancy and infertility of cows with high accuracy in the conditions of livestock farms in veterinary medicine, paying attention to the results in cows of different ages. The effectiveness of the instrumental method in the diagnosis of cows under the age of 2 years, 3-5 years of pregnancy is 83%, infertility is 84.6%; and in cows older than 5 years of pregnancy is 79.6%, infertility is 63.6%.

There are many methods for early detection of pregnancy in cows, but the most accurate and common are ultrasound and rectal palpation.
