Abstract:The differences in microcosmic and macroscopic structures between Wenshi partridge chicken and Sanhuang chicken were investigated. Nutritional evaluation showed that the nutritional value of Wenshi partridge chicken was lower than that of Sanhuang chicken. However, Wenshi partridge chicken contained high-quality protein according to the ideal model of FAO/WHO. The first limiting amino acids in the two kinds of muscles were Met and Cys according to both the amino acids score and chemistry score. The hardness, resilience, chewing character and recoverability of Sanhuang chicken were higher than those of Wenshi partridge chicken. The results indicated that contravariance ability and stability of myosin and actin in Sanhuang chicken were better than those in Wenshi chicken. But contravariance ability and stability of myogen in Sanhuang chicken were worse than thosed in Wenshi chicken.
