Sweet Potato Meal versus Ground Corn in the Ration of Dairy Cows

Abstract

A comparative study of the effect of ground snapped white corn and sweet potato meal on the liveweight and milk and butterf at production of dairy cows was conducted during the spring and summer of 1946. Analysis of variance revealed no significant differences in the milk and butterfat production or in the liveweights of cows when the sweet potato meal or corn constituted 36 per cent of the concentrate mixture. The sweet potato meal was as palatable as the ground corn when each of these concentrates constituted 36 per cent of the concentrate mixture. No excessive or objectionable laxative effect upon the digestive system of the cows was noted when they were fed the sweet potato meal mixture. The cows fed the sweet potato meal had a sleeker, brighter hair coat than did those fed the corn ration. © 1948, American Dairy Science Association. All rights reserved.
