SUMMARY

Eighteen entire Sudan Desert Lambs 4 – 6 month old were entered in a fattening trial for 70 days at an initial liveweight of 20.9 i 1.4 Kg. They were fed on rations which contained either 45% (group A), 30% (group B) or 15% (group C) groundnut hay. Average daily gain and feed intake were significantly (p < 0.01) higher in group A and B compared with group C. The mean values of these were 205, 170 and 120 g. and 1.32, 1.31 and 1.01 Kg, respectively. Feed conversion ratio (FCR) was signi- fincatly (P < 0.05) improved in group A (6.48) compared with group C (8.74). Lambs in group B showed no significant effect for FCR (7.94) to those values in either of group A or C. All carcass parameters were not significantly affected by feeding treatments.
