[Objective] The aim was to study the effect of the muscle histological characteristics of Haimen goats on meat quality. [Method] TwelveCmonthCold Haimen goats and Bore × Haimen F1 (♂) were used as the materials to systematically research the muscle histological properties of different sexes and muscles. [Result] The results revealed that the muscle fiber area and myofibril diameter, sarcomere length, light band length, dark band length, hall band length of quadriceps femoris of Haimen female goats were extremely significantly higher than male goats (P 0.01); However, that of longissimus dorsi muscle was extremely significantly lower than male goats (P 0.01). There was significant difference (P 0.05) or extremely significant difference (P 0.01) between muscle microstructure and ultrastructure among the same sex and different muscles. There were a large number of mitochondria, glycogen granules and fat droplet within muscle fiber from Haimen male goats, which indicated that oxidative metabolism rate was high, water retention was good and the meat was tender, succulent and distinct. [Conclusion] The study provided theoretical basis for breeding, development and utilization of Haimen goats and variety evaluation of local goats in China.
