[Method] Three male and three female goats of twelve-month-old Danba goat were selected to slaughter,and their slaughter performance, muscle qulity and mus- cle nutrients were determined. [Result] The pre-slaughter weights, dressing percent- ages, meat percentages and carcass meat production rates of the male and female Danba goats were （25.83±1.04） and （18.50±2.29） kg, （45.18±0.78）% and （38.89± 2.08）%, （33.76±1.4）% and （28.59±1.99）%, and （74.30±0.85）% and （74.08±0.65）%, respectively. The carcass length, carcass hind leg circumstance, carcass hind leg length, lumbar muscle thickness, hind leg meat yield, shoulder muscle yield and breast meat yield of male goats were significantly higher than those of female goats （P〈0.05）, and no significant differenceswere found in other carcass size and carcass segmentation indices between male and female goats （P〉0.05）. There were small differences in muscle fiber properties, muscle quality, muscle nutritional composition, muscle mineral content and muscle heavy metal content between male and female goats （P〈0.05）. A total of 18 kinds of amino acids were detected in the male and female goats. The EAA/TAAs and EANNEAAs of male and female goats were （39.56±0.26）% and （39.48±0.66）%, and （65.45±0.71）% and （65.43±1.80）%, respec- tively. [Conclusion] This study will provide the basis for the understanding of the resource characteristics of Danba goat.展开更多
