Abstract The quality characteristics and nutrient composition of breast muscles from Taihe black-bone silky fowls were comparatively evaluated with those of crossbred black-bone silky fowls and AA broilers. Proximate nutrients, lipids, amino acid composition and 11 mineral elements were determined. Our data showed that the moisture content of muscles from both male and female Taihe silky fowls was higher than that of other breeds. Male crossbred silky fowls had higher crude protein content than other breeds, while the opposite result was observed for female crossbred silky fowls. Taihe silky fowls of both genders showed significantly higher crude fat content but lower total cholesterol content (P < 0.05). Male and female Taihe and crossbred silky fowls were significantly richer in free fatty acids than AA broilers (P < 0.05). However, males and females of these breeds presented no significant differences in total, essential or umami amino acid contents (P > 0.05). In addition, iron, copper, chromium and selenium were significantly abundant in male and female silky fowls than in AA broilers (P < 0.05). The contents of heavy metals including lead, cadmium and arsenic in all three breeds were below national limits.
