Research on the vitamin A requirements of sheep, and more especially the vitamin A value of carotene, is more limited than that with cattle. The objective of this experiment was to study effects of various levels of vitamin A and carotene supplementation with lambs previously depleted of vitamin A stores. Liver storage and blood levels of vitamin A following repletion were considered the primary measures of the value of the various levels of supplementation.
