Cow felling depending on the state of exchange of substances in the synchronization of estrus

Abstract

The article presents the results of studies on the fertilization of cows, depending on the state of metabolism before the synchronization of estrus. It was found that a decrease in the content of total protein, calcium, inorganic phosphorus and carotene in the serum, together with the development of compensated acidosis, significantly reduces the level of fertilization of cows.
