In this study 106 heads apparently normal, Ghezel sheep breed f rorn National Animal Research Institute , were randomly chosen and divided into five groups of pregnant and Non - preg. ewes
rams, lactating male and female lambs. The values of total protein, albumin, globulin, albumin / globulin ratio creatlnlne, glucose, urea, uric acid, cholesterol, alanine aminotransferse (ALT), aspartate aminotransferase (AST) , sodium potassium were measured , also the effects of age, weight and sex on the above mentioned ‘arameters were calculated and the mean values ± of the studied arameters were determind as following total protein 7.08 ± 0.08 gr /dl, albumin: 3.14 ± 0.06 gr /dl, globulin: 3.99 ± 0.31 gr/dl, A /G ratio :0.80 ± 0.12 creatinine: 1.43 ± 0.03 mg/dl, glucose : 48.70 ± 0.53mg / dl, urea: 36.39 ± 0.90 mg / dl. uric acid:2.08 ± 0.14 mg/dl, cholesterol: 73.58 ± 2.9omg/dl, ALT :22.46 ± 0.70 U/L, AST:74.40 ± 2.25u/l ,sodium:
potassium : 149.57 ± 2.12 meq / L, potassium : 5.13 ± 0.16 meq / L. Using the ANOVA and Tukey’s test, the effects of age and sex on the studied parameters were determined. Studentt test was used to identify the significant differences between male and female groups in the studied parameters. There was a significant difference between serum levels of albumin, uric acid and potassium levels in the male and female groups.
