The elimination of quotas in the EU has led to a significant increase in milk production with more cows and higher yields per animal. In the case of Ireland, where there is a model based on grazing, many variables must be fine-tuned to achieve an optimal economic benefit. The type of pasture and the cow breed are among them.

Ryegrass is the most common species in wet climate areas as it is the most economical feed for dairy cows.

White clover is a legume and as such has the property of nitrogen fixation, so the nitrogen fertilizer needs of the soils are significantly reduced.
