Abstract
Abstract MENADIONE sodium bisulfite, a water-soluble form of the provitamin 2-methyl-1,4-naphthoquinone, is used as a source of vitamin K in poultry feeds. This form differs in its vitamin K activity from the fat-soluble menadione (Frost and Spruth, 1955). The data presented in this report indicate that this difference is not necessarily a function, or, at least, not only a function of the change in solubility status, since another water-soluble form of menadione, namely, menadione dimethyl pyrimidinol bisulfite, 2 differs in its activity from menadione sodium bisulfite. EXPERIMENTAL Fourteen groups of 20 cross-bred, female chicks received a purified vitamin K-deficient diet (Griminger, 1962a) from hatching to 1 week of age. At that time group uniformity was increased by eliminating 4 chicks with extreme weights. From 1 to 3 weeks of age the chicks received the K-deficient diet supplemented with 0.2% sulfaquinoxaline and with seven graded levels of each of the two water-soluble menadione…
