Abstract
Abstract Extrapolating from single-site animal studies of the effects of water soluble carbohydrate (WSC) on methane and nitrogen emissions requires knowledge of geographical and temporal variation in plant chemical constituents. To provide this, samples of grazed pasture were collected from experiments at four different latitudes over one year. At each site, one high-sugar perennial ryegrass (HSG) and two control cultivars of perennial ryegrass, were sampled at each grazing during a 12-month period and analysed for concentrations of WSC, crude protein (CP) and fibre (NDF). Compared with the controls the HSG was higher in WSC (overall mean 299 vs 260 g WSC/kg DM; P
