Khabarovsky Krai, Vostochnoe village).
The analysis of primary zootechnical registration in the OAO «Zarya» of Khabarovsky District exposed the important
influence of age and the first calving season on the productive longevity of Holstein cows. In the defective feeding
conditions calvings before the 24-months age lead to the sharp shortening of animals’ life duration.
