| SUMMARY Twenty four Ossimi lambs averaged 14.5 kg and aged 16 weeks were used to study the effect of 4 pelleted complete feeds (PCF) on digestibility, growth performance and wool characteristics. The lambs were divided into 4 groups (6 animals in each). The animal groups were fed on PCF without urea or tafta (C), 2% urea without tafla (U), 2% urea + 3% tafla (U1T) and 2.5% urea + 3% tafla (U2T). Growth trial lasted for 24 weeks which were divided into 3 successive periods. By the end of the growth trial, 3 animals from each group were taken for digestibility trials. The main results were, the crude fibre (CF) digestibility of U2T was significantly (p<0.05) lower than that of the other rations, while the other nutrients digestibility was not significantly affected with different rations. The group U had the lowest value of daily body gain (DBG) while the group U2T had the highest value. The yield of clean wool of the groups fed urea and tafla (U1T and U2T) was significantly higher than that of groups U or C. The wool quality of the groups U1T and U2T was better than groups U or C . Conclusively, adding tafla clay in pelleted complete feed improved growth performance and wool yield and its characteristics. Moreover, U2T was the most economic diet among all tested ones. | ||||
