I will just add to that. UCD Lyons Farm has high economic breeding index, EBI, cows. Teagasc would have tried out lower EBI cows on various systems. Have the researchers come to a conclusion as to which is the best from a climate point of view with regard to carbon footprint and so on? Which is the best or is that research ongoing?
