Traditional vs Modern: Role of Breed Type in Determining Enteric Methane Emissions from Cattle Grazing as Part of Contrasting Grassland-Based Systems
Table 3
Effects of breed type and production system on animal performance and methane (CH4) emissions of beef steers (where WB = Welsh Black, LimX = Limousin cross; Lowland = rotational grazing of monoculture perennial ryegrass, Upland = extensive grazing of a diverse hill sward).
