Offered differential approach to the use of uteruses of a different level of productivity, in particular uteruses of the М- class - in pedigree-linear hybridization. Set efficiency of the use of a new to the type ULW-3 as paternal form in hybridization. Realizable estimation of animals of different variants of hybridization after selection indexes.
