Although the significance of vitamin A in the nutrition of the young dairy calf is well recognized, the effects of ingestion of large amounts of this vitamin, particularly as related to other blood constituents, have received comparatively little attention. Investigations with other species suggest that there may be a relationship between vitamin A intake and the level of the serum lipids. Josephs (1942) reported that the administration of large amounts of vitamin A increased total serum lipids in both normal and vitamin A-deficient rats, the effect being much greater and persisting longer in the latter. Similar results were observed in vitamin A-deficient infants (Josephs, 1945). Children with the nephrotic syndrome also displayed a marked rise in total plasma lipids following administration of vitamin A alcohol in aqueous dispersion (Kagan, Thomas, Jordan and Abt, 1950). The objective of the present study was to ascertain the effect of massive doses of vitamin A in oily and in aqueous dispersion on the blood plasma vitamin A and fat levels in dairy calves which were near the state of vitamin A deficiency.
