The formation of simple linear models for predicting the breeding values of animals
The basic principle of estimating breeding value using linear models (matrix equations) according to generally accepted international standards (BLUP) is performed. An algorithm is showed and a mathematical apparatus is described for implementing a system for estimating and selecting the best breeding animals for further reproduction. The main principles of building a workable breeding values rating system in a modern format in concordance with the claims of ISAG /ICAR (Interbull) are given down. The necessity of forming a unified database information system (IS DB) for keeping information about primary registration, identification and data on animal productivity is declared. The description of the principle of checking up the reliability of linear models by the value of the residual error and the conformity of the Mendel model of inheritance is presented.
