EFFECT OF USING RATIONS DIFFERENT IN NITROGEN SOURCES ON GROWTH AND BLOOD PARAMETERS FOR GROWING LOCAL SHARABI CALF UNDER ENVIRONMENTCONDITION OF NINEVEH PROVINCE

Abstract

This study was conducted on Rashidia station farm, Department of Agri. Res. in Mosul, on twelve sharabi local calves in 10 ± 2 weeks of age and average body weight (47.67±3.13 kg.) were used, calves were divided into three groups and fed ad libitum on three Iso-nitrogenous and Iso-caloric rations but different in nitrogen sources(Soybean meal,Nigellia sativa meal and Urea) in calf starter rations, in addition to feeding milk until weaning weigh at 100 kg. Blood samples were collected from jugular vein from all calves that reach weaning weight. The results was indicated that no significant effect of nitrogen sources on calves weight, daily weight gain ,feed consumption, bloods count of red and white cell, hemoglobin ,packed cell volume, platelets counts ,total protein, globulin, albumin, glycerol ,triglyceride, urea and glucose)parameters. It was concluded that nigellia sativa meal and urea can used and replaced soybean meal in starter rations for sharabi local calves
