dc.description.abstract Question has been raised concerning the vitamin A potency of stored yellow corn. Samples of 1954 corn and 1948-49 stored corn were analyzed for provitamin A content by a separation and chemical determination of the carotene and crude cryptoxanthin contents. The 1948-49 sample was found to have a vitamin A activity of about 800 units per pound, slightly less than one-third of that of 1964 corn. In this work 1 mg. of carotene was given a vitamin A value of 1.6 unit-s and cryptoxanthin one-half that value, which are the vitamin A activities previously determined by bioassay with rats. Although much vitamin A activity apparently had been lost during storage of yellow corn, there was still the problem of the availability of the remaining vitamin A for animals. This was studied, using weanling pigs as the experimental animal. en_US
