What is it about?
In this paper we are exploring the capacity to mitigate enteric CH4 emissions of cattle under grazing conditions. We demonstrated that methane emissions were 14% lower (and emission intensity was four times lower) when animals grazed a high-quality pasture in comparison with a low-quality one.

Why is it important?
Our findings show that it is possible to reduce emissions in grazing systems without incorporation of other feedstuffs (e.g. grains) through improvement in the forage quality offered.
Perspectives
I hope this article presents a good perspective for reducing emissions in grazing systems. We are showing the relationship between forage quality and environmental care. The high-quality pasture used in this work was similar to those used under intensive grazing management by farmers in several parts of the world. We think that the potential use of pasture quality as a strategy for mitigating methane emissions raises the need to strengthen research about this topic.
