【摘要】：为研究拉萨白鸡生长性能和肌肉品质,对拉萨白鸡生长状况、屠宰性能及肉品质进行了测定。结果显示:在42、120、150、180、210日龄,拉萨白鸡公鸡体重极显著高于母鸡体重(P0.01)。公鸡、母鸡180日龄的屠体重、屠宰率、半净膛率差异极显著(P0.01),母鸡胸肌率显著高于公鸡(P0.05);不同性别相同部位比较,母鸡胸肌肉色L值与剪切力显著高于公鸡(P0.05)。公鸡腿肌胶原蛋白含量极显著高于母鸡(P0.01),蛋白含量极显著低于母鸡(P0.01);相同性别不同部位比较,公鸡胸肌和腿肌的肉色、p H值、失水率、剪切力均差异极显著(P0.01),母鸡胸肌和腿肌的肉色、失水率差异极显著(P0.01),公鸡胸肌和腿肌的胶原蛋白、肌内脂肪、水分、蛋白质含量均差异极显著(P0.01),母鸡胸肌和腿肌的肌内脂肪、蛋白质含量差异极显著(P0.01)。
[Abstract]:For the study of Lhasa white chicken growth performance and meat quality, growth status of Lhasa white chicken slaughter performance and meat quality were determined. The results show: at the age of 42120150180210 days, Lhasa white chicken cock was significantly higher than the hen (P0.01). The rooster, hen 180 days of age, carcass weight, slaughter rate, half net bore rate significantly (P0.01), the pectoral muscle was significantly higher than that of cock (P0.05); to compare the different parts of the same sex, hen breast meat color L value and shear stress were higher than that in males (P0.05). The leg muscle collagen content was significantly higher than the hens (P0.01), protein content was significantly lower than the hen (P0.01); comparison of different parts of the same sex, the rooster breast and leg muscle color, P H value, water loss rate, shear stress were significantly different (P0.01), chicken breast and leg muscle color, water loss rate significantly (P0.01), the breast and leg muscle in muscle collagen. The difference of fat, water and protein content was very significant (P0.01). The difference of intramuscular fat and protein content in the breast and leg muscles of hens was very significant (P0.01).
