通过预防技术研究，发现鸡的抗出血维生素是脂溶性的，存在于其各种来源的不皂化物的易溶非甾醇部分中，即，猪肝脂肪（一种非常有效的来源），鸡蛋蛋黄（不是非常丰富），大麻籽和某些蔬菜（良好的来源），黄玉米，糙米和向日葵籽（非常差）。鱼肝油实际上不含维生素，它不能与维生素等同。A或D，因为数量大。这些维生素的饮食是完全无效的，在预防疾病，由于它的缺乏。它看起来像维生素。E在空气中的溶解性和耐热性稍有不同，但与E不同的是，大量的小麦胚芽或小麦胚芽油不能完全保护小麦胚芽不受出血性的影响。有人建议，长期维生素。K可用作抗出血因子。
The antihemorrhagic vitamin of the chick, studied by the preventive technique, was found to be fat-soluble and to occur in the easily soluble non-sterol fraction of the unsaponifiable matter of its various sources, i.e., hog liver fat (a very potent source), yolk of hen''s egg (not extremely rich), hemp seed and certain vegetables (good sources), yellow corn, unpolished rice and sunflower seeds (very poor). Cod liver oil is practically devoid of it. It cannot be identical with vit. A or D, because large amts. of these vitamins in the diet are completely ineffective in preventing the disease due to its lack. It resembles vit. E somewhat in solubility and resistance to heating in air but differs from E in that large quantities of wheat germ or wheat germ oil do not afford a complete protection against the hemorrhagic diathesis. It is suggested that the term vit. K be used for the antihemorrhagic factor.
