The adult male quail birds were treated orally with the doses 23, 16 mg/kg b.w of copper hydroxide (25% WP) and 47, 31 mg/kg b.w of copper oxychloride (28.5% WP) respectively for 5 consecutive days and then left for 3 days without treatment as a recovery period. Blood samples were obtained from each group at the end of treatment and recovery periods. Some hematological and biochemical parameters were assayed in whole blood , plasma or serum. The hematological results showed a significant increase in hematocrite percentage at the end of treatment period by the low dose of copper oxychloride, also a significant increase in WBC's count and significant decrease in hematocrite percentage were proved by the low dose of copper oxychloride at the end of recovery period. The biochemical results showed significant increase in total protein conc. by the high used dose of copper hydroxide, also significant decrease in albumin conc. and significant increase in ALT enzyme activity by the high and low doses of copper oxychloride respectively was shown at the end of treatment period . Significant increase in albumin conc. was detected by the low dose of copper hydroxide at the end of recovery period. Also a significant decrease was resulted in plasma phospholipids conc. in low dose treated group of copper oxychloride at the end of treatment period and in total cholesterol conc. by the low dose of copper hydroxide at the end of recovery period. These results reflected the low acute toxicity of the doses of both formulations to male adult quail birds under the laboratory conditions.
