Professor Karina Pierce:

On which is the best, I would say we are very similar. I could not say we are better. The reasons are, basically, that we use high genetics and high amounts of home-grown feedstuffs. We are utilising 10 tonnes to 12 tonnes of grass, for example. The metrics being advocated from a Teagasc perspective are actually being implemented on the UCD farm. I do not know if there is a best in it. We are both using good genetics, a lot of grass and high-producing fertile cows. We are skinning the cat in a different way. Basically we are looking at a low-carbon footprint. Using the figures that Teagasc produced, I believe we are very similar in that regard.
