| Summary: | Twelve Local calves in 12 ± 2 weeks of age and average body weight (46.17±3.22 kg.)were used in this study at Rashidia research station in Mousl,Iraq. Calves were divided into three groups and fed ad libium on three Iso-nitrogenous <br /> and Iso-caloric rations contained different level of dry rumen content (0,8 and 16%) instead of barely in calf starter rations, in addition to milk as 10% 0f body weight until weaning weigh at 100 kg. The results was indicated that no significant effect of experiential rations on daily weight gain ,feed consumption, hematological and biochemical parameters ,but mathematical decreased in dry matter intake by increasing dry rumen content percentage in calf starter ration. The results indicated also that calves weights ,count of red and white cell, ,lymphocyte cell percentage, hemoglobin, total protein, globulin and blood urea were increased significantly (P≤0.05), while percentages of natural and acedo cells, blood glucose, glycerol and triglyceride were decreased significantly (P≤0.05) by increasing animal age |
