| 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). The results showed that Leizhou Black ducks had higher slaughter rate and whole net carcass rate. The meat quality and nutrient content of muscle in female were higher than male, the breast muscle was better than thigh. |
