摘  要:
对1岁龄蓝孔雀屠宰性能和肉质特性进行了分析测定,结果表明:蓝孔雀平均活重、屠宰率、半净膛率、全净膛率、胸肌率、腿肌率、腹脂率、肝脏比率分别为3 535 g、86.44%、77.70%、74.05%、23.72%、20.12%、1.15%1、.33%,肌肉pH1、pH24值分别为6.25、5.52,失水率为19.93%,系水力为72.21%,熟肉率为69.38%,剪切力为3.32 kg.f,肌纤维平均直径为47.42μm.在屠宰性能方面,与樱桃谷鸭、三黄鸡相比,蓝孔雀具有较高的活重、全净膛率、胸肌率和腿肌率,但屠宰率、半净膛率和腹脂率较两者低;在肉质特性方面,蓝孔雀具有较高的系水力、熟肉率和剪切力.

摘  要:
The carcass characteristics and meat quality of 1-year-old blue peafowl were measured in this paper.The results showed that live weights,dressing percentages,semi-eviscerated weights,eviscerated weights,breast muscle yield,leg muscle yield,the abdomen-fat rate liver rate of blue peafowl were 3 535 g,86.44 %,77.70 %,74.05 %,23.72 %,20.12 %,1.15 % and 1.33 %.The pH1 values,pH24 values,rate of water loss,water holding capacity,cooking percentage,shear force values,diameter of muscle fiber of blue peafowl were 6.25,5.52,19.93 %,72.21 %,69.38 %,3.32 kg·f and 47.42 μm.In terms of carcass characteristics,the blue peafowl has higher live weights,eviscerated weights,breast muscle yield and leg muscle yield than cherry valley duck and three-yellow chicken;however,has lower dressing percentages,semi-eviscerated weights and the abdomen-fat rate.In terms of meat quality,the blue peafowl has higher water holding capacity,cooking percentage and shear force values.
