摘　　要：对成都麻羊成年母羊和6月龄母羊进行了屠宰测定,分析了肉和常乳的常规营养成分以及肉氨基酸含量.结果表明,成都麻羊成年母羊宰前活重31.31±2.10kg、胴体重14.68±1.52kg、净肉重12.15±1.32kg、内脂重1.40±0.08kg、屠宰率为51.36±2.24%、净肉率为31.77±4.0%;成都麻羊6月龄母羊宰前活重16.2±0.43、胴体重7.0±0.41kg、净肉重5.2±0.32kg、屠宰率为43.21±1.32%、净肉率为38.81±1.49%、.成年母羊鲜肉常规营养成分含量(%)水份71.44±0.22,粗蛋白20.41±0.04,粗脂肪10.69±0.12,能量7968.90±175.16KJ/kg.成年母羊鲜肉氨基酸含量(mg/100g)氨基酸总量27940.0±550.0、必需氨基酸11035.0±65.0、非必需氨基酸16905.0±495.0;成都麻羊乳常规营养成分含量(g/L)乳蛋白45.8±2.2,乳脂59.3±3.3、乳糖44.0±3.2.6-month-old and adult Chengdu Ma Goats are slaughtered to detect and analyse mutton and milk general nutrient contents and mutton amino acids. The result shows that： the live weight of female adult is 31.31±2.10kg before slaughter, the average carcass weight 14.68±1.52kg, the average dressing weight 12.15±1.32kg, the weight of offal fat 1.40±0.08kg. The percentage of net mutton is 51.36±2.24%; the adult goat slaughter percentage 38.81±1.494%. The average live weight of 6-month-old goat is 16.2±0.43kg before slaughter; the average carcass weight 7.0±0.41 kg, the dressing weight 5.2±0.32kg. The slaughter percentage is 43.21±69% in fresh mutton. The energy is 7968.9±175.16KJ per Kg fresh mutton. The total aminol.32%, the dressing percentage 32.1±1.02%, Crude moisture 71.44%, crude protein 21.41%, crude fat 10.69±0.12, total amino acids 27940.0±550.0 mg per 100g fresh mutton, essential amino acids 11035.0±65mg per 100g fresh mutton, non-essential amino acids 16905.0±495.00mg per 100g fresh mutton. Lactoprotein in milk is 45.8±2.2g/L, lactose 44.0±3.2 g/L, and milk fat 59.3±3.3 g/L.
