How EBI (Economic Breeding Index) improves dairy cow fertility

WHAT IS THE 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 information on seven sub-indexes related to profitable milk production including;

• Milk Production

• Fertility

• Calving Performance

• Beef Carcass

• Cow Maintenance

• Management

• Health

HOW IS EBI IMPROVING DAIRY COW FERTILITY?

Fertility is continuously improving in Ireland’s largely block-calving dairy industry despite tough growing seasons and ambitious herd expansion plans since milk quotas ended. And the average national calving interval has fallen by 14 days in just over 5 years.

The economic breeding index (EBI), launched by the Irish Cattle Breeding Federation (ICBF) in 2001, rates cows on suitability for spring-calving, grass-based systems, with fertility weightings of 23.1% on calving interval and 10% on survival.

As well as improving fertility the EBI Index aims to develop a cow which can deliver the following:

• High solids

• Increased Longevity

• Functional cattle with reduced stature but balanced frames

• Respond to concentrate when fed if milk price is high, but if milk price is low can sustain themselves off low input whilst getting back in calf with minimal costs.
