- W2324334502 abstract "PROBABLY no other nutrient has been so extensively studied as carotene as a vitamin A source for poultry and the larger domestic animals with more variable results. The International Unit (or U.S.P. unit) of vitamin A is equivalent to 0.6 micrograms of β-carotene or 0.3 micrograms of vitamin A (alcohol). These values were established by The Expert Committee on Biological Standardization of the World Health Organization (1950) after careful statistical evaluation of collaborative rat curative-growth bioassays of β-carotene and vitamin A. After an initial collaborative assay in Great Britain in 1939, another collaborative assay was sponsored by the United States Pharmacopeia (1946–47) with 12 laboratories participating. Based on the potency of 1,667,000 I.U. per gram for β-carotene, the potency of vitamin A (alcohol) was found to be 3,300,000 I.U. per gram. Thus, one microgram of vitamin A (alcohol) is recognized as equivalent to 2 micrograms of β-carotene in biological…" @default.
