摘要
采用冰冻切片法、借助TIGER细胞图像分析仪对南海麻黄鸡、江西鸡、黄鸡M系、黄鸡N系、黄鸡K系的胸部肌肉的肌纤维直径和肌纤维密度进行了测定。结果表明:①肌纤维直径由小到大依次为江西鸡(30.1±3.1)μm、南海麻黄鸡(35.3±7.8)μm、黄鸡N系(36.7±1.9)μm、黄鸡K系(37.2±0.7)μm、黄鸡M系(38.1±3.1)μm,江西鸡与黄鸡N系、黄鸡K系之间的差异均达到极显著水平(P<0.01)。②肌纤维密度由小到大依次为黄鸡K系(424.5±39.3)根/mm2、M系(465.5±91.9)根/mm2、N系(471.5±63.0)根/mm2、南海麻黄鸡(568.1±59.7)根/mm2和江西鸡(655.5±182.6)根/mm2。③优质肉鸡的肌纤维直径和密度与肌肉品质之间有密切关系。
With the method of freeze section and the TIGER Cell Image Analyzer,the chest muscle fiber diameters and densities which came from five broiler breeds were measured. The five broiler breeds were Jiangxi yellow chicken,Nanhai yellow chicken,Yellow chicken M,Yellow chicken N and Yellow chicken K,which were raised under the same condition from 1 to 56 days age. The result indicated that:①the muscle fiber diameters were (30.1±3.1) μm in Jiangxi yellow chicken,(35.3±7.8) μm in Nanhai yellow chicken,(36.7±1.9) μm in Yellow chicken N strain,(37.2±0.7) μm in Yellow chicken K strain,(38.1±3.1) μm in Yellow chicken M strain.②The muscle fiber density were(424.5±39.3) trichomes/mm2 in Yellow chicken K strain,(465.5±91.9) trichomes/mm2 in Yellow chicken M strain,(471.5±63.0)trichomes/mm2 in Yellow chicken N strain,(568.1±59.7) trichomes/mm2 in Nanhai yellow chicken,(655.5±182.6)trichomes/mm2 in Jiangxi yellow chicken.③there was close relation between muscle fiber diameter and density and muscle quality.
