Forecasting Pedigree Value of Bulls at the Early Ontogenesis Stage
Abstract
Possibility of early forecasting of pedigree value of bulls (n=59) of Belarusian black-motley breed on data of their origin is studied. It is determined that the best information on pedigree value for that purpose is the information about pedigree value of parents. Correlation between indices of pedigree value of sons and parents is curvilinear. Correlation ration in pairs «father-son» makes: on average at sampling - 0,02, on fathers with index OPC on milk yields 97-99 % - 0,13, on fathers with index OPC 100-102 % - +0,44, and on fathers with index OPC 103 % and higher not only -0,09. The similar regularity was determined in correlation of pedigree value of mothers and sons.
