The first experiment: Twenty five rams divided into five groups (5 rams each) were used in experiment 1(digestion trial). The concentrate to roughage ratio was 60:40 and the animals were fed according to 4 % of body weight. Group one (G1; control) fed 60% concentrated feed mixture (CFM) and 40% clover hay (CH). Group two and three (G2 and G3) fed control diet with replacement of 50% of CH by dried olive cake (DOC), with adding fibrolytic enzymes (2g/h/d) to the diet of G3. The half quantity of CH was replaced by silage olive cake (SOC) in the diets of group four and five (G4 and G5), with adding fibrolytic enzymes (2g/h/d) only for G5. The second experiment, fifty five late pregnant Barki ewes (average 2-4 years and average body weight 45 kg) were used. Ewes were divided randomly to five equal groups and fed the experimental rations. The third experiment using twenty five of Barki male lambs (average body weight of 24kg ± 0.8kg and 4-5 months of age) were divided into 5 similar groups (5 lambs each) and were fed the experimental rations. The digestibility of DM, OM, CF and NFE were insignificantly (p>0.05) improved in the experimental rations compared with the control. Digestion coefficient, of CP and EE in rations were higher significantly (p<0.05) compared to the control ration specialized Mahmoud Mohamed Shaaban Mohamed ; Supervised Mohamed Ahmed Hanafy , Galal Eldin Mohamed Abdulaziz , Mohamed Mahmoud Mohamed Mostafa Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Animal Production Issued also as CD blood Dried olive cake olive cake silage http://172.23.153.220/th.pdf http://172.23.153.220/th.pdf EG-GiCUC 170102 20250223031634.0 eng
