Extract

Increasing animal productivity increases daily enteric methane (CH4) emissions but reduces CH4 output per unit of animal production. Irish livestock production systems are characterised by a high dependence on grazed pasture. Increased nitrogen (N) fertiliser application can increase animal productivity through increased intake. The objective of this trial was to assess the effect of N level application and pasture maturity on in vitro methane production.
