GENOMIC SELECTION AS A NECESSARY CONDITION FOR THE DEVELOPMENT OF CATTLE BREEDING IN RUSSIA
The article reveals the importance of genomic selection application and development of Russian index of cattle breeding value. The results of work by Russian geneticists and livestock breeders, who created a series of remarkable breeds and types of agricultural animals, may be lost due to the fact that the assessment methods of their breeding qualities do not correspond to the evaluation system adopted in several countries, which occupy leading positions in the production of certain types of products. Instead of using the achievements in the world of genetics and breeding to improve separate economic-useful properties of the local cattle, the process of absorption of domestic breeds and types is growing very fast. It is necessary at least to be equal in a technical and technological sense, and also to have a clear evaluation system for specialists of other countries to prove their success at the animal products market, including its tribal component. Increasing genetic level of the cattle will help to ensure a reliable assessment of pedigree and productive qualities of bulls and of breeding stock; a high degree of inheritance of the most important economic-useful properties that are a target of the selection; a small interval between generations of animals. The current system of evaluation of pedigree and productive qualities of milk and milk-meat cattle in Russia is outdated. We need a statistical model that can explain the effect of the environment and all individual relations.on the implementation of the genetic potential of the animal. Russian breeders need their own breeding value indexes (BVI), because it is necessary for preservation of yet available competitive advantages of Russian breeds and types of agricultural animals.
