Abstract

The features of connection of the suckling productivity and
reproductive ability of cows of Ukrainian red suckling breed are
studied. It is set that with the increase of suckling productivity
level, reproductive ability of cows gets worse. It is defined, that
an optimal service-period is within 51-90 days; for highly productive
cows duration of service period to 121 day is not a critical.
An index which characterized the level of cows suckling
productivity in taking into account their reproductive ability is
offered. The results of researches enable to improve the use of
suckling cattle in an economy by correct organization of herd
reproduction.
