Abstract

A linear estimation of the constitution type of 255 cows of the first-calf cows of the Ukrainian Red and White dairy breed has been conducted under conditions of the basic breeding farms of Vinnytsia region. It is established that the use of the linear classification method makes it possible to objectively determine the level of development of exterior signs of the first-calf cows of the Ukrainian Red and White dairy breed, which, according to the estimates, are characterized by a good development of the signs of the dairy type. At the same time, daughters of the bulls of Elewaishna line 1491007.65 and Cavaler 162027.72 by the complex of linear descriptive signs of the first-calf cows received the highest estimates. The use of this technique for assessment of the bull-producers by the exterior type of their daughters, certain cows of the breeding group, high-value founder and family members contributes to consolidation of dairy herds and fulfilment of the genetic potential.
