NEWSLETTER HIGHLIGHTS
By Pat Donnellan
The task of matching a bullâs figures to his fame is ICBFâs primary function. ICBF âŹuro-Star figures have always caused a difference of opinion between people in terms of their own experience of a bull. Thatâs only normal â not all of the good and bad points of a bullâs offspring are recorded in the ICBF database.

Also, the ICBF index values give an overall âon averageâ prediction of how a bull will breed. Some people might only have had the few good animals off a bull and not the poorer quality ones. That is understandably what certain opinions are based on.
