| This study was conducted on 12 male Sharabi calves,10-12 months old with initial body weight 183±50 kg.were divided into three groups,fed on same basal ration but different in type of feed additive ,first treatment(T1= basal ration) , second treatment (T2= basal ration +25 g.of stymulan cattle / 100 kg.ration) and third treatment (T3= basal ration + 200 g. of Sorbotiol/ 100 kg.ration).and fed for 16 weeks,and study the effect of feed additives on some hematological & biochemical parameters .The results indicated that adding feed additives to second ration has significantly (P≤0.05) increased hemoglobin, red & white blood cell count, packed cell volume , lymphocyte cell percentages )as compared with other rations, also total protein, albumin, globulin were increased significantly (P≤0.05) , while cholesterol , triglycerides and urea were decreased significantly (P≤0.05) with adding feed additive to second and third treatments as compared to first treatment. Also hemoglobin, red & white blood cell count, packed cell volume , lymphocyte cell percentage , total protein, albumin, globulin and urea were increased significantly(P≤0.05) ,while the percentages of acidophile and netrophile, cholesterol and triglycerides were decreased significantly(P≤0.05)as animal get older . |
