摘要: 目的 了解SPF金黄仓鼠乳的组成成分,并与其他啮齿类动物(小鼠、大鼠、豚鼠)乳、兔乳、牛乳以及婴儿配方乳进行比较分析。方法 按照国家标准,采用凯氏定氮法、电感耦合等离子体质谱法(ICP-MS)等测定金黄仓鼠乳中基本营养成分; 使用氨基酸自动分析仪测定氨基酸含量。结果 金黄仓鼠乳100 g主要营养成分含量如下: 水分86.4 g、蛋白质6.94 g、脂肪2.70 g、乳糖2.21g; 矿物质元素钙120.00 mg、镁20.10 mg、磷82.05 mg、锌1.470 mg等; 16种氨基酸,水解氨基酸总含量为61 mg/g,必需氨基酸含量24.4 mg/g,占氨基酸总量的40%。结论 金黄仓鼠乳汁具有高蛋白、低脂肪、低乳糖的特点,为无菌金黄仓鼠配方乳的配制提供了科学依据。

Abstract: Objective To determine the main nutritional components of SPF golden hamster milk and compare with other rodents milk (mice, rats, guinea pigs), rabbit milk, cow milk and infant formula milk. Methods According to the national standard, the essential nutrients of golden hamster milk were detected by Kjeldahl and ICP-MS. The content of amino acids was detected by an automatic amino acid analyzer. Results The main nutrient contents of 100 g golden hamster milk were as follows: water 86.4 g, protein 6.94 g, fat 2.70 g, lactose 2.21 g, mineral elements calcium 120.00 mg, magnesium 20.10 mg, phosphorus 82.05 mg, zinc 1.470 mg, etc. The total content of hydrolyzed amino acids was 61mg/g, and the content of essential amino acids was 24.4 mg/g, accounting for 0.4 of the total amount of amino acids. Conclusion The milk of golden hamster is characterized by high protein, low fat and low lactose, which provides a scientific basis for the formulation of sterile golden hamster formula milk.
