The best mathematic model for estimation of genetic parameters and evaluation of breeding value for reproduction traits in dairy cattle will be chosen. Characteristic for classification of beef cattle reproduction will be choosen according to evaluation of database. Important factors influencing reproduction in working conditions will be determined. The methodology for breeding value estimation suitable for routine use will be developed. The methodology based on relationship of breeding animals, which combine different source of information, will be use to breeding value evaluation. The important factors that influence classification of growth of animals and genetic parameters will be determined. The methodology for breeding value evaluation will be put to breeding organization for routine use. (en)
