Vitamin D Studies in Cattle

Abstract

In previous reports from this Station, experimental data have been submitted upon the antirachitic value of sun-cured hay for dairy cattle (1), the vitamin D sparing action of certain magnesium compounds when only small amounts of this vitamin were present in the dairy ration (2), and the essential nature of radiant energy in the dietary r~gime of the dairy calf (3). The present report is concerned with the antirachitic value of corn silage for dairy cattle.
