Sweet potatoes are a high moisture feed in their fresh state, but the dry matter yield per hectare of high yield cultivars is competitive with many other feed sources. The roots and especially the vines contain relatively high calcium concentrations with lower levels of phosphorus in contrast with feed grains of corn, barley, wheat, and sorghum. Raw sweet potatoes as a feed for growing-finishing pigs requires more soybean meal or some other protein supplement to obtain satisfactory performance than does a feed of dried sweet potato chips. The continuous efforts by many workers have been made to obtain better utilization of sweet potatoes as animal feed such as determining the optimum proportion of dried sweet potato chips to corn in pig and poultry diets, defining the most effective process to enhance the nutritive value of sweet potatoes, and the feeding of a high-protein cultivar to animals.
