摘要 [Objectives] This study was conducted to understand the biological characteristics of Duoluo goats. [Methods] With male and female Duoluo goats as the research object, related performance indexes were determined and analyzed after slaughter. [Results] (1) The weights of one-year-old male and female Duoluo goats before slaughter were (25.68±2.37) and (24.51±1.97) kg, respectively; the dressing percentages were (43.55±3.24)% and (43.84±3.42)%, respectively; and the net meat percentages were (33.02±2.32)% and (34.19±2.46)%, respectively. (2) The cooked meat rates of male and female Duoluo goats were (65.49±1.42)% and (65.36±1.55)%, respectively; the shearing force was (5.48±1.24) and (5.65±1.02) N, respectively; and the loin-eye muscle areas were (8.95±1.72) and (8.82±1.15) cm2, respectively. (3) The protein contents of male and female Duoluo goats were (20.07±0.42) and (19.47±1.22) g/100 g, respectively; and the fat contents were (1.30±0.80)% and (2.92±0.55)%, respectively; and the cholesterol contents were (71.76±11.47) and (74.83±2.68) mg/100 g, respectively; (4) The Ca contents of male and female Duoluo goats were (69.53±10.89) and (63.00±4.56) mg/kg, respectively; the Fe contents were (16.73±1.83) and (14.77±0.58) mg/kg, respectively; and the Zn contents were (38.47±3.68) and (31.83±2.22) mg/kg, respectively. (5) In the muscles of male and female Duoluo goats, the contents of essential amino acids were (7.44±0.24) and (7.26±0.41) g/100 g, respectively; the contents of non-essential amino acids were (11.81±0.33) and (11.42±0.67) g/100 g, respectively; and the contents of flavor amino acids were (8.79±0.27) and (8.42±0.57) g/100 g, respectively. [Conclusions] This study lays a foundation for the excavation and utilization of the resource, Duoluo goats.
