Supplementary table for paper: Enteric methane emission of dairy cows in 3 grass-based systems: Unrestricted grazing, zero-grazing, and grass silage

The supplementary table shows the Least Squares means of feed intake, feed efficiency, lactation characteristics, body weight and gaseous emissions of dairy cows by grass-based system, period and year. The grass-based systems included unrestricted grazing (UG), unrestricted zero-grazing (ZG) and unrestricted grass silage (GS). The roughage type was fresh grass outdoors (grazing sward) for UG, fresh grass indoors (zero-grazing sward) for ZG and grass silage for GS.
