稻鸭共生对鸭肉品质和屠宰性能的影响

Effect of Rice-duck Mutualism on Meat Quality and Slaughter Performance of Duck

以云南麻鸭为试验材料,分别在稻鸭共生(稻鸭组)和常规网上平养(常规组)两种饲养模式下饲养至体重达1.8kg,测定其常规肉品质和部分屠宰性能。结果表明:①两组间鸭肉失水率、嫩度、熟肉率、肉色亮度值和红度值无显著差异(P>0.05);稻鸭组的pH值显著高于常规组(P<0.05);肉色黄度值B极显著高于常规组(P<0.01)。②两组间屠宰率、半净膛率、全净膛率、胸肉率差异不显著(P>0.05);稻鸭组的皮脂厚、腹脂率比常规组分别降低了18.52%、11.76%(P<0.05);腿肉率提高了11.40%(P<0.05)。③稻鸭组的生长速度明显慢于常规组。

Yunnan Ma ducks were selected as experimental material,which were fed in the mode of rice-duck mutualism （RDM） and conventional rearing （CR） until ducks＇ body weight reached 1.8 kg,then general index of meat quality and slaughter performance were measured. The results showed：There were no significant differences （P〉0.05） in water-loss capacity,tenderness,cooked meat ratio,meat color redness and lightness between two groups;pH and meat color yellowness （B＊） of RDM were higher than that of CR,and the differences were significant respectively. There were no significant differences （P〉0.05）in the percentage of slaughter yield,eviscerated yield with giblet,eviscerated yield and breast muscle yield between two groups ;However,compared with CR,Sebum thickness and percentage of abdominal fat of RDM decreased by 18.52%, 11.76% （P〈0.05） respectively,and tbe percentage of leg muscle yield of RDM increased by11.40% （P〈0.05）. The growth rate of RDM was significantly slower than that of CR.
