The work contains results of determinations of protein, fat, lactose, vitamin C and minerals: Ca, P, Fe, Mn, Cu, Zn, Na, K, Cl as well as toxic metals like Hg, Cd and Pb in goat milk. The nonmineral components were determined by general approved analytical methods. Minerals like Ca, P, Fe, Mn, Cu, Zn, Na, K, Cd and Pb were determined by the flame ASA method and mercury by "cold vapour" technique. Chloride were determined by Mohr method and phosphorus as phosphates by colorimetric method with ammonium molybdate. Mean percentage content of protein, fat, lactose and ash were: 3.2 (range 2.7-3.7); 3.9 (3.2-6.5); 4.1 (3.9-4.9); 0.87 (0.84-1.00) respectively. Mean content of ascorbic acid amounted 0.53 mg/100 g (range 0.19-1.42), and the content of minerals were as follows: Ca 130 (range 102-150); P 127 (115-151); Mg 14.1 (12.6-16.3); Mn 0.026 (0.019-0.037); Cu 0.04 (0.02-0.08); Zn 0.54 (0.40-1.25); Fe 0.047 (0.020-0.097); Na 42.4 (20.8-59.5); K 163 (138-190); Cl 168 (128-180). The levels of toxic metals were mostly below the allowable limits, mercury from 3.8 to 14.5 micrograms/kg, cadmium < 0.01 micrograms/kg. In the case of lead a 40% of investigated samples were above the allowable limits.
该研究测定了山羊奶中的蛋白质、脂肪、乳糖、维生素C以及矿物质（钙、磷、铁、锰、铜、锌、钠、钾、氯），还有汞、镉和铅等有毒金属的含量。非矿物质成分采用普遍认可的分析方法测定。钙、磷、铁、锰、铜、锌、钠、钾、镉和铅等矿物质通过火焰原子吸收光谱法测定，汞通过“冷蒸气”技术测定。氯采用莫尔法测定，磷以磷酸盐形式通过钼酸铵比色法测定。蛋白质、脂肪、乳糖和灰分的平均百分含量分别为：3.2（范围2.7 - 3.7）；3.9（3.2 - 6.5）；4.1（3.9 - 4.9）；0.87（0.84 - 1.00）。抗坏血酸的平均含量为0.53毫克/100克（范围0.19 - 1.42），矿物质含量如下：钙130（范围102 - 150）；磷127（115 - 151）；镁14.1（12.6 - 16.3）；锰0.026（0.019 - 0.037）；铜0.04（0.02 - 0.08）；锌0.54（0.40 - 1.25）；铁0.047（0.020 - 0.097）；钠42.4（20.8 - 59.5）；钾163（138 - 190）；氯168（128 - 180）。有毒金属含量大多低于允许限值，汞含量为3.8至14.5微克/千克，镉含量<0.01微克/千克。在铅的情况下，40%的被调查样本超过了允许限值。
