中文摘要:

      目的 研究不同养殖模式下清远麻鸡的组织学评价标准。方法 测定不同养殖模式下清远麻鸡肌肉的肌节长度、肌纤维直径、肌纤维密度、肌纤维面积比例、结缔组织面积比例和脂肪面积比例。结果 不同养殖模式出产的清远麻鸡组织学性状差别较大, 农户散养模式出产的清远麻鸡肌节最长、肌纤维直径最粗、肌纤维面积比最大, 走地鸡养殖模式次之, 笼养模式出产的清远麻鸡肌纤维直径最小、密度最大、结缔组织面积比和脂肪组织面积比最大。结论 依据组织学特性对清远麻鸡的鸡肉品质进行了分级, 初步制定了清远麻鸡组织学分级评价标准。

英文摘要:

      Objective To study the histological evaluation criteria of Qingyuan partridge under different breeding modes. Methods The sarcomere length, muscle fiber diameter, muscle fiber density, muscle fiber area ratio, connective tissue area ratio and fat area ratio of Qingyuan Ma chicken muscle under different culture modes were determined. Results The histological traits of Qingyuan partridge chicken produced by different culture models were quite different. The Qingyuan partridge chicken broth produced by the farmer's free-range model had the longest sarcoma, the largest muscle fiber diameter and the largest muscle fiber area ratio, followed by the chicken farming mode. The Qingyuan partridge chicken muscle fiber produced in the cage mode had the smallest diameter, the highest density, the connective tissue area ratio and the fat tissue area ratio. Conclusion According to the histological characteristics, the chicken quality of Qingyuan partridge is graded, and the evaluation criteria of histological grade of Qingyuan partridge chicken are preliminarily established.
