Popis:	Methane production from Welsh ponies fed 2 isoenergetic diets (NE basis) at maintenance was studied in a crossover design with 4 mature geldings (230 ± 10.5 kg BW, mean ± SE). Treatments included a roughage-only (R) diet (5.1 kg DM/d) or a roughage plus cereal mix (RC) diet (2.5 kg DM hay/d plus 1.1 kg DM cereal mix/d). For both diets, the same grass hay was used (898 g DM/kg and 4.5 MJ NEm/kg DM) and a commercial cereal mix was used in the RC diet (890 g DM/kg and 9.6 MJ NEm/kg DM). Ponies were housed in pairs in climate-controlled respiration chambers. Carbon dioxide production (CO2), oxygen (O2) consumption, and CH4 production were measured over 3 consecutive days. Heat production (HP) rates were calculated from gaseous exchange. Feces were collected quantitatively to determine dietary nutrient digestibility. Dry matter intake differed between diets (P
