Аннотация:The aim of this research was to compare the bioactive compound content and quality traits of breast meat from male and female Korean native ducks (KND) and commercial ducks (CD, Cherry Valley). Meat from three 6-wk old birds of each sex from KND and CD were evaluated for carcass and breast weights, pH, color, cooking loss, shear force, and bioactive compound (creatine, carnosine, anserine, betaine, and L-carnitine) content. KND showed significantly higher carcass weights than CD whereas no such difference (p>0.05) was found between male and female ducks. The breed and sex had no significant effects on the breast weight, pH value, and shear force. However, KND had significantly lower cooking loss values than did CD. Creatine, anserine, and L-carnitine contents were significantly higher in KND than in CD and were predominant in female ducks compared to males. The results of this study provide rare information regarding the amounts and the determinants of several bioactive compounds in duck meat, which can be useful for selection and breeding programs, and for popularizing indigenous duck meat.
