Two hundred ml of milk were obtained from a lactating Stejneger's beaked whale stranded at Ninilchik, Alaska on 21 Oct, 1980. Total solids (41%) were similar to values reported for sperm and belukha whales, while fat (17%) was half as great and crude protein (17%) was 2-4 times greater than in milk of these species. Lactose was not detected. Calcium (0.22%) was greater than reported for pigmy sperm whales but less than for blue whales. Phosphorus (0.07%) was less than for any of the above species. Sodium and potassium concentrations were 0.13% and 0.11%, respectively. Values (microgram/g) for other elements analyzed (magnesium, 42; iron, 35; copper, 2.6; zinc, 1.5; manganese, 0.3; selenium, 0.36) have not been reported for whale milk. Based on SDS-gel electropherograms, this whale milk did not contain a whey protein corresponding to cattle milk alpha-lactalbumin. A blue-green pigment in the milk was identified as biliverdin.
1980年10月21日，从一头搁浅在阿拉斯加尼尼利克的斯特勒海牛的哺乳期母鲸身上获取了200毫升乳汁。总固体含量（41%）与抹香鲸和白鲸的报告值相似，而脂肪含量（17%）只有这些物种乳汁的一半，粗蛋白含量（17%）则是这些物种乳汁的2至4倍。未检测到乳糖。钙含量（0.22%）高于小抹香鲸的报告值，但低于蓝鲸。磷含量（0.07%）低于上述任何物种。钠和钾的浓度分别为0.13%和0.11%。所分析的其他元素（镁，42；铁，35；铜，2.6；锌，1.5；锰，0.3；硒，0.36）的含量（微克/克）在鲸类乳汁中尚未见报道。基于十二烷基硫酸钠凝胶电泳图谱，这种鲸类乳汁不含与牛乳α-乳白蛋白相对应的乳清蛋白。乳汁中的一种蓝绿色色素被鉴定为胆绿素。
