Shantar L. Selectionand genetic evaluation of transitional genotypes of the holsteinized type the red dari cfttle being

The research aim was: to establish a relationship between the exterior, constitution type, live weight, technological characteristics and productive signs of the red steppe dairy cattle and transitional genotypes of the holsteinised type (on the "Lenin" pedigree farm in Holopristansky district, Kherson region); to reveal genetic factors responsible for the formation of utility characters and to study the environmental influence on them. It was determined that the animals of the transitional genotypes exceed the red steppe cattle in live weight, exterior constitution type, technological characteristics and productive signs. The use of the animals of the transitional genotypes with a blood share of ? -:3/4 - and ? of the perfecting breed of the holsteineised type of the red steppe dairy cattle will ensure an average increase in milk yields ( based on three lactations) by 392; 390 and 86 kg compared with purebred cows. I he research results have been applied on the pedigree farm "Sarya" of the Belozersky district, Kherson region.
