中文摘要: 对不同品种生鲜驴乳中常规营养成分，如脂肪、蛋白质、乳糖、干物质含量、维生素C、氨基酸和矿物质等进行比较分析。结果显示，不同品种鲜驴乳中蛋白质、脂肪、水分、干物质、乳糖、维生素C、滴定酸度和pH值变化范围分别为 1.38 g/100 g～ 1.77 g/100 g、0.75 g/100 g～ 1.08 g/100 g、88.89 g/100 g～ 90.64 g/100 g、9.38 g/100 g～ 12.64 g/100 g、4.32 g/100 g～5.56 g/100 g、2.01 g/100 g～3.12 g/100 g、4.48°T～4.74°T、7.09～7.18。德州黑驴生鲜乳显示出最高的氨基酸总量（1 867.89 mg/kg），德州黑驴生鲜乳中的必需氨基酸显著高于疆岳驴、新疆驴、果拉驴（P<0.05）。德州黑驴生鲜乳中钙、硒含量较其他品种要高，而果拉驴生鲜乳中磷、锌含量较其他品种要高。
Abstract:The contents of conventional nutrients such as fat，protein，lactose，dry matter，vitamin C，amino acids and minerals in fresh donkey milk of different breeds were compared and analyzed.The results showed that the protein，fat，water，dry matter，lactose，vitamin C，titratable acidity and pH of fresh donkey milk were 1.38 g/100 g-1.77 g/100 g，0.75 g/100 g-1.08 g/100 g，88.89 g/100 g-90.64 g/100 g，9.38 g/100 g-12.64 g/100 g，4.32 g/100 g-5.56 g/100 g，2.01 g/100 g-3.12 g/100 g，4.48 °T-4.74 °T and 7.09-7.18，respectively.The fresh milk of Dezhou black donkey showed the highest total amino acid content （1 867.89 mg/kg）.The essential amino acids in fresh milk of Dezhou black donkey were significantly higher than those of Jiangyue donkey，Xinjiang donkey and Guola donkey（P<0.05）.The contents of calcium and selenium in fresh milk of Dezhou black donkey were higher than those of other breeds，while the contents of phosphorus and zinc in fresh milk of guola donkey were higher than those of other breeds.
