Essay

The work is dedicated to studying the influence of development duration of embryonic period on organism natural resistance of cattle, growth intensity in ontogeny and on milk productivity. It is established that the heifers with short and middle duration of embryogeny are characterized by the best indices of cellular and hymoral factors of organism protection. Sung animals maintain the ability to more intensive growth both in embryonic and postembryionic periods of development. The cows with short embryonic development period give more milk during the lactation, and they are better milked.The given mathematical formula allows to define the possible milk produc-tivity during the first days after the birth.
