Effect of cobalt chloride on some antioxidants and Lipid Peroxidation in the Liver of Coturnix coturnix Japonica

This study was conducted to determine the level of effectiveness of non-enzymatic antioxidants glutathione and enzymatic antioxidants catalase and the level of malonidedehyde in the liver of quail birds Coturnix coturnix japonica, (100) birds at the age of (22) days distributed in a cage and divided into four groups that included a group control as for the rest of the groups was exposed to cobalt chloride at Dosages of (30،50 and 70 mg/kg) dry weight for periods of (5, 15 and 30) days. The results showed that there was no significant decrease in the level of Glutathione in the liver for the exposure period of (5) days compared to the control group. During the exposure period (15 and 30) days، it was a significant decrease in the level of glutathione in all Dosages used in the experiment compared to the control group. The level of catalase showed that there was no significant decrease in the short exposure period of (5) days compared to the control group. In the exposure period of (15and 30) days، it was observed from the results that there was a significant decrease in the level of effectiveness.
