Abstract: Randomly selected healthy disease-free sixty 300 days of age Leizhou Black ducks, male and female half-and-half, carried on a slaughter test. The results showed that the whole net carcass rate and lean percentage of male duck were significantly higher than female(P<0.05), the percentage of abdominal fat and subcutaneous fat percentage of female duck were extremely significantly higher than male(P<0.01), but its breast muscle percentage was extremely significantly lower than male(P<0.01), the meat color (L, a, b), cooking lose rate of thigh muscle and tenderness of breast muscle in male and female were all extremely significantly different(P<0.01), the crude protein content of thigh and breast muscle in female duck were extremely significantly higher than male(P<0.01), the fat of breast in female was significantly higher than male(P<0.05).
