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.
