Study of the effect of high dietary iodine on blood of broiler chickens

ABSTRACT

The aim of this study was to elucidate the effect of high dietary iodine on some biochemical and hematological parameters of broiler chickens. The obtained data showed that the thyroidal hormones concentration [T3 and T4], alkaline phosphatase activity [ALP], aspartate aminotransferase activity [ASAT] and urea level were significantly increased in the sera of chickens kept on high dietary iodine [150 ppm in drinking water] at the 3rd and the 6th weeks post treatment. On the other h and, calcium, iron and creatinine levels were significantly increased [P <0.05] at the 6th week only. Concerning the blood picture, the obtained results revealed that, the red blood cells [RBCs] count, lymphocytic percentage, hemoglobin [Hb] concentration and packed cell volume [PCV] values were significantly increased in the iodine supplemented chickens, while the white blood cells [WBCs] count and heterophil percentage were significantly decreased in the same group
