For 32 days silage of good organoleptic quality, made from elephant grass (Pennisetum purpureum) cut after 78 days of growth and 3.4% of molasses, was given to 4 sheep and faeces were collected for 7 days. The chemical compositions of the fresh forage and of the silage are shown. The silage had 23.84% DM. Average digestibility of the silage was for DM 62.63, crude protein 49.00, crude fibre 68.30, N-free extract 58.30, ether extract 72.92, energy 60.63 and organic matter 62.83%. Fresh silage supplied 0.652 kcal and DM 2.735 kcal digestible energy/g and total digestible nutrients were 14.4 and 60.4%.
