May 10, 2021, 6:00 am The Economic Breeding Index (EBI) is a measure of the genetic potential of an animal. Research by Teagasc was undertaken to validate if EBI is delivering at farm level using E-profit monitor data. The research findings have shown that every €1 increase in EBI will result in a €2 gain in net profit/cow. So, cows with an EBI of €100 are leaving €200 more profit per lactation than cows with an EBI of €0. The Index is comprised of seven Sub-Indexes; milk production and fertility are the two most valuable traits in the index. EBI Milk When selecting on milk sub-index, Teagasc have included a threshold figure of ≥€50 for individual bulls.
