Comparative study of muscle quality in Princess chicken and SanHuang chicken

The present experiment was conducted to compare the differences of muscle quality in Princess chicken and SanHuang chicken and to provide a reference for muscle evaluating, breeding and variety extending of Princess Chicken. The homolateral breast muscle and leg muscle were collected from the experimental chicken for muscle quality testing. Sensory meat qualities, brief chemical constituents and muscle histology characteristics of two varieties were collected for comparative analysis. The result showed that the storageloss, shear force and incarnadine of Princess chicken muscle was significantly lower than those of SanHuang chicken. Princess chicken had a relatively higher cooking percentage, pH value, muscle fiber density, crude protein, crude fat, crude ash content and a relatively lower fiber diameter, moisture content, abdominal fat rate and the thickness of subcutaneous fat than those of SanHuang chicken.Being compared in the mass, the muscle quality of Princess chicken was better than that of SanHuang chicken, but incarnadine should be focused on breakthrough in the future.
