SUMMARY
Two groups ofsix and seven Kenana bull calves were fattened on a
treatment diet (A ) ot'80 ‘X, cotton seed meal ( CSM) and unconventional
diet (B ) of8O% concentrate mixture, respectively, from an average 68 kg
initial live- weight to 152.9 t 1.0 kg slaughter weight. A brtter t"e:d lot
performance was observed for calves fed the concentrate mixture diet. No
significant differences were found between the two groups in structural
tissue components of the carcass. It has been concluded that the traditional
use of CSM for t'att<n‘ng cattle in the Sudan should be discouraged and
incorporation of this feed should be minimized levels required to maintain
the desired protein content in the diets.
