Ireland: study on Economic Breeding Index (EBI)

In Ireland, a study of Teagasc, which is an institute that is providing research, advisory and education in agriculture, shows that an improvement of the Economic Breeding Index (EBI), which is a measure of the genetic potential of an animal, of ten euro per herd leads to a reduction of greenhouse gas emissions of three percent per year. This because cows with an higher EBI are more fertile, which reduces the replacement rate of a farm and reduces the calving interval. Also cows with a higher EBI produce more milk and solids. This results in a better efficiency of production, with a lower emission of CO2 equivalents.
