【摘要】 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。更多还原

【Abstract】 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 the percentage of leg muscle yield of RDM increased by 11.40%(P<0.05).The growth rate of RDM was significantly slower than that of CR.更多还原
