FIELD: animal farming, in particular, dual-purpose cattle breeding. SUBSTANCE: method involves selecting animals for reproducing or discarding animals from herd on the basis of newly worked specific indexes for evaluation of productivity correlated with constitutional characteristics. Usage of proposed specific indexes allows situation in herd to be evaluated in complexity and at more complete level and selection to be conducted by optimum features to provide high productivity and strong constitution for retaining cattle breed genofond. EFFECT: increased efficiency and provision for producing improved cattle breed. 3 tbl
