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 averagebody weight (47.67±3.13 kg.) were used, calves were divided into three groupsand fed ad libitum on three Iso-nitrogenous and Iso-caloric rations but differentin nitrogen sources(Soybean meal,Nigellia sativa meal and Urea) in calf starterrations, in addition to feeding milk until weaning weigh at 100 kg. Bloodsamples were collected from jugular vein from all calves that reach weaningweight. The results was indicated that no significant effect of nitrogen sourceson calves weight, daily weight gain ,feed consumption, bloods count of red andwhite cell, hemoglobin ,packed cell volume, platelets counts ,total protein,globulin, albumin, glycerol ,triglyceride, urea and glucose)parameters. It wasconcluded that nigellia sativa meal and urea can used and replaced soybeanmeal in starter rations for sharabi local calves.
