Abstract

In modern conditions of livestock is the problem of reproduction and prevention of sterility. A high level of reproduction and milk production of cows is possible only in healthy animals. Specialists of farms and complexes are often discarded highly productive cows in the first, second lactation due to violations of reproductive functions, diseases of the limbs and of the mammary gland, and this causes enormous economic damage. Only reasonable prevention and proper approach to solving these challenges will produce the desired results in import substitution.
