An experiment was carried out to study the effect of short term feeding of Methyl Parathion (25 or 50 ppm) with or without a performance enhancer Zigbir (500 ppm), on some haematological and serum biochemical attributes in commercial broilers. The blood samples were collected from the wing vein of these birds at 5 and 7 weeks of age. The results of the present investigation revealed that was a significant (P<0.01) reduction in the hemoglobin concentration and PCV of the birds fed with MPA (25 or 50 ppm). The total leukocyte count, total erythrocyte count and the various erythrocyte indices (MCV, MCH) were not fount to be significantly (P<0.01) affected by dietary MPA (25 or 50 ppm). The various enzyme profiles in the serum (SGOT, SGPT and alkaline phosphatase) showed a significant (P<0.01) increase in their mean values, How ever supplementation of Zigbir showed a little beneficial effect in reducing these values in the serum. A significant reduction in serum albumen, serum globulin and a significant increase in A: G ratios, BUN and serum glucose have been observed in the birds fed with MPA (25 or 50 ppm). Similarly a significant (P<0.01) increase in serum sodium and a significant decrease in serum potassium contents of the broilers fed with MPA (25 or 50 ppm) have been recorded at both the intervals of blood collection.
