[Heritability and ways of selection of pedigreed bulls according to reproductive capacity].

Abstract excerpt

Significant heritability (to 0.92) by sperm output data from 248 simmental stud bulls has been determined using correlation and dispersion methods. The additive component of heritability is not significant. Application of the best bulls is most effective for selection on sperm productivity.
