Abstract
Three feeding trials were conducted with beef cattle in which a combination of supplemental vitamin E and K to a no-hay finishing ration resulted in superior performance. The vitamin supplemented cattle averaged 9% faster liveweight gains and improved feed conversion. A fourth cattle feeding trial was conducted in which supplemental selenium was added to a similar finishing cattle ration. The liveweight gain response from selenium was fully as high or higher than the responses obtained with supplemental vitamins. Also, supplemental selenium, as well as supplemental vitamin A, exerted a sparing action upon liver vitamin E. The possible importance of these results and some of the limitations in interpreting them in feeding practice were discussed. Copyright © 1963. American Society of Animal Science .
