Methods of assessment of worth of genetic resources of animals

Abstract

The purpose. Analysis and generalization of existing methods of assessment of genetic worth of animals. Methods. Materials and publications which map foreign experience of assessment of genetic resources of animals are studied. Results. The survey of existing methods of assessment of genetic worth of animals is made. International experience of assessment of breeding programs based on formation of selection indexes is surveyed. Conclusions. Genetic worth of cows and bulls of dairy and dairy-meat breeds is evaluated on the basis of special procedures of assessment of breeding value, genetic intransmutations (trends) and determination of economic significance of these attributes in indexes of selection.
