Four Sudan desert sheep about 18 months old were housed in individual metabolism cages and fed to appetite on elephant grass (Pennisetum purpureum) cut 3 times at 13-week intervals, at heights of 3, 4 to 5 and 5 to 6 ft, and preserved as sun-dried hay with 94% DM, chopped to 5 to 7.5 cm. Each cut was tested in a separate trial with a 10-day preliminary period and a 7-day collection period. Crude protein content of the grass decreased significantly between cuts. Crude fibre content was less in the second cut possibly because of new tillering, and most in the third. Voluntary intake was greatest in the first cut and least in the third. There was no significant difference among cuts for digestibility of DM or organic matter.
