Abstract
A total number of 21 growing lambs rearing in Mallawy Research Station with an average of 4-5 months old and 17.30 kg. body weight an average were used in this study. Lambs were assigned randomly to three diets for 100 days. The experimental diets were manipulated to replace the concentrate feed mixture (CFM) by 0,20, and 40 % of dried filter cake, OFC for treatments (01, 02 and 03) respectively. The control diet (01) was composed of CFM, berseem hay and wheat straw, whereas in the other 2 diets (02 and 03), 20 % and 40 % of CM were replaced by OFC, respectively. At the end of the experiment blood samples were taken from each lamb and analyzed for estimation of metal content (Iron, Fe; copper, Cu, zinc, Zn; manganese, Mn; nickel, Ni; cadmium, Cd; chromium, Cr and lead, Pb) by using atomic absorption spectrophotometer. As well as physical measurements of the wool for its characteristics (greasy & clean fleece weight, stable length, fiber ~ end diameter) were studied. The obtained results revealed that addition of DFC to the rations did not significantly alter the concentrations of Fe, Cu. Zn. Mn,. N. Cd, Cr, and Pb, except a significant effect (p < 0.05) between 02. ard 03 treatments in nid<el concentrations. The corresponding figures for wool measurements also, were not significant
