摘 要 采 用 了冬夏季 蒙古羊 一自然 .鸟珠穆沁羊 一自然和鸟珠穆 沁羊 一圈养 羊的半腱 肌和肱 三头肌为研 究 对 象.利 用分光光度法测定样 品结缔组 织中的胶 原蛋 白的含量及 其热 溶解性 。结果表 明:3个品 种羊不 同季节屠 宰后其半腱肌和 肱三头肌 中结缔组织 的胶 原蛋 白含 量最 高,肌 内膜 胶原 蛋 白含 量 明显 高于肌 束膜 中胶原蛋 白含 量。其 中,丰腱肌 中的结缔组织 的胶原蛋 白含 量分别均呈现显 著下 降趋 势(P<0.05),但是 同一种 羊冬、夏 两季 间 半腱 肌 中的结缔组 织的胶 原蛋 白含量 变化 不显著 ,同一季节屠宰的 3个品种羊半腱肌 的结缔组 织、肌 内膜 、肌束膜 中胶 原蛋 白含量均 呈现 显著差异(P<0.05)。肱三头肌的结缔组 织、肌 内膜 中胶原蛋 白含量 均呈现显著 差异(P< O.05)。夏 季鸟珠 穆沁羊 一自然与 圈养 的肱 三 头肌 中胶原 蛋 白含 量 变化 不显著 。3个品种 羊不 同季节 的羊半腱肌 和肱三 头肌 结缔 组织 内胶 原蛋 白热溶解性存在 显著 差异 (P<0.05),夏 季半腱 肌 结缔组织 内胶 原蛋 白热 溶解性 高 于冬季半腱肌 ,冬季肱三头肌结缔组 织 内胶 原蛋 白热溶解性明显 高于夏季 。蒙古羊 一自然的结缔组 织 内胶 原蛋 白 热 溶 解 性 明 显 高 于鸟 珠 穆 沁 羊 。
