Economic breeding Index (EBI) is a single figure profit index aimed at helping farmers identify the most profitable bulls and cows for breeding dairy herd replacements.
It comprises of information on seven sub-indexes related to profitable milk production.
The main goals of the EBI index are to breed high fertility, easily managed cows of moderate stature, who produce high quality milk in a cost effective manner with a regular calving interval.
The economic values in the index are based on data collected from Irish Dairy Farms and the Dairy Industry. These values were last updated in May 2017.
