Abstract: Sixty Najdi lambs, weighing 23.5 kg were randomly placed in a 2X3 factorial arrangement of two levels of dietary energy (70:30 and 25:75 concentrate: roughage ratio) and three levels of poultry offal meal supplementation (0, 50 and 100 g POM/kg DM). Lambs were individually fed ad libitum and slaughtered after 120-days feeding period; thereafter, slaughter weight, hot carcass weight, daily dry matter intake, feed to gain ratio and carcass composition including lean, bone and separable at for each lamb were determined. The results showed that all studied traits were significantly influenced by the concentrate to roughage ratio; being superior (P<0.01) for the lambs fed on high concentrate diets than for the high roughage fed lamb. Lambs fed on high concentrate diet supplemented with 10% POM produced 9.17, .39 and 0.45 kg more (P<0.01) body, carcass and wool weight, respectively, Over the 120 days feeding than for comparable POM-free diet group. Consequently, the former lambs consumed 1.5 kg or 21.1 MJ less dry matter intake or metabolizable energy intake respectively, per kg body gain than those lambs fed on POM-free diet. On the other hand, there was no significant effect due to POM supplementation on all carcass and performance data of the lambs fed on high roughage diets.
