The growth and development of black-motley breed heifers having different feeding activity in the suckling period of growing

УДК 636.

The article presents the results of the research on patterns of growth and development of breeding black-motley breed heifers having different indices of feeding activity in the early stages of suckling growing period. Young animals with high food activity in the initial stage of growing, eventually has intensive metabolism, greater live weight, and earlier maturity. Passive in relation to food animals have a tendency to levelling existing differences. At the same time these animals don’t achieve full compensation in the development by the time of the first insemination.
