Prediction of productivity of pigs on the basis of regression models
Abstract
Prediction formula for the genetic component of the breeding value of animals by direct kinship from mother to daughter and from father to son were developed, as soon as on the basis of this relationship one can significantly improve the accuracy of estimate. A method for verifying the genetic component of evaluation of breeding values indices with low heritability was developed (multiple pregnancy, milk yield, number of piglets on 21st day). It is determined that assessment by self productivity data of the maternal part of lineage can increase the genetic component of traits with low heritability by 25,2-58,4 %.
