The results showed that there was no significant difference in meat quality between male and female indiv iduals, however, the contents of globulin (GLO), alkaline phosphatase (AK P), triglyceride (TG), total cholesterol, total protein in drake individuals were significantly higher than female ducks (P0.05) except for A lb/GLO ratio among various serum biochemical indices. Additionally , the
