Factors Affecting Some Hematology and Serum Biochemical Parameters in Three Indigenous Sheep Breeds

Abstract

This study was aimed to investigate the effect of some factors such as breed, age and sex on some hematological and biochemical parameters at Duhok province; Kurdistan region of Iraq. Blood samples from 120 healthy sheep (60 males and 60 females) from three flocks around Duhok city were used. The overall mean for Packed Cell Volume (PCV), Hemoglobin (HB), Erythrocyte Sedimentation Rate (ESR), Neutrophils to Lymphocyte ratio (N/L), Total Protein (TP), Albumin (ALB), Globulin (GLO), Glucose (GLU), Cholesterol (CHO) and Blood Urea (BU) were 27.35± 3.16 %, 8.93 ± 1.07 g/dl, 8.88 ± 2.76 mm/7hrs, 1.32 ± 0.37 %, 6.00± 0.34 g/dl, 2.10 ± 0.26 g/dl, 3.61 ± 0.42 g/dl, 60.36 ± 15.04 mg/dl, 46.69 ± 11.81 mg/dl and  41.75 ± 9.84  mg/dl, respectively.

There were a highly significant PCV, HB, ESR, N/L and BU with the lowest Albumin (p<0.05) in Karadi breed when you compared to others. While Naimy sheep were recorded significantly the highest GLU (p<0.001) than both breeds, but TP and GLO in the last breed were the lower than Karadi breed significantly (p<0.01) and (p<0.001), respectively. Cholesterol was lower significantly (p<0.001) in Awassi breed when compared with Karadi. Also there were significantly higher ESR, N/L (p<0.001) and GLU (p<0.05) with the lowest PCV, HB (p<0.01) in Adults sheep. In this study there is a non-significant differences of sex of animal for all studied traits with exception of N/L ratio, (female > Male) (p<0.01), But these parameters were remained within the normal ranges for healthy sheep.
