 Abstract
The objective of this study was to investigate the current state of carcass weight distribution and external quality of domestic duck products. A total of 419,164 duck heads were used for the carcass weight distribution analysis. From the results, the average, mode, median, and quartile were 2,164.4, 2,000, 2,200, and 300 g, respectively. Furthermore, carcass yield averaged 70.1% from the live weights of domestic duck products. Duck carcasses had 28.4% external defects and 4.8% external damage. Moreover, the appearance ratio of discoloration was 34.1% and, in particular, the leg region was significantly (p<0.05) higher than that of the other regions. The feather removal defect ratio averaged 44% from the duck carcass surface. The ratio of disjointed and broken bones averaged 9.91% and mostly appeared in wing and leg parts. Fat content was significantly (p<0.05) higher in carcasses with weights >2.3 kg than that of other carcass weight levels, suggesting that market live weight of domestic duck products must be greater than a minimum of 3 kg.
