Abstract
A Survey was carried out on three flocks at three locations namely (Duhok, Zakho and Emadia) in Dohuk governorate to study the effect of different physiological status on blood parameters (blood hemoglobin, cholesterol, glucose and total protein in blood) and ( concentration of T3 ,T4 and TSH). Eighteen does 3-4 years old were ear tagged. Blood samples (10 ml) were withdrawn every 45 days from each animal for nine months. Physiological status was divided into three stages namely pregnancy, lactation and drying and mating. Data showed the following results: Blood hemoglobin, cholesterol, sugar, total protein, T3, T4 and TSH averaged respectively, 10.00 gm/100m1, 99.33 mg/100 ml, 47.63 mg/100 ml5.82 gm/100ml 12.22 mg/100 ml, 103.9 ng/100 ml and 0.341 ngm /ml. With the exception of total protein and T4, A highly significant (P <0.01) effect of physiological stage of the animals on all studied traits were noticed. blood cholesterol and TSH, were higher during drying and mating season. Blood sugar was at highest during pregnancy, whereas hemoglobin was highest during suckling stage. A highly significant effect (P<0.01) of location on all studied traits were observed.
