Abstract

The estimation of breeding value of Aberdeen Angus in the age of 210 days was made through years 1997 to 2007. It was inquiried influnce of increase of amount of information to stability of breeding values (for direct effect and maternal effect, too). Negative corelation was approved between direct effect and maternal effect. Favourable relation was proved between the amount of information about animal and achieved breeding value and between values of animals in running time.
