Descrição: A tendency was noted for an increase in the prevalence of ovarian hypofunction in cows with an increase in their milk productivity. On average, it is diagnosed in 28.9-43.9% of examined cows. It was noted that the prevalence of hypofunction decreased with the number of calvings in animals. In first-calf cows, ovarian hypofunction was registered in 37.6-52.8% of cases, which is 1.3-2.0 times higher compared to cows of the second lactation and 1.3-2.8 times higher compared to cows of the third or more lactations . The number of diagnosed cystic formations also increased with increasing milk production. In highly productive animals, ovarian cystic formations are diagnosed 1.3-1.8 times more often, including follicular - 1.4-1.9 times and luteal - 1.2-1.7 times.
