Animal forages are scarce in quantity and are inadequate in quality especially in dry season. Alternatively, sweetpotato vines can provide more protein and dry matter. This presentation reports on a ‘proof of concept’ project seeking to identify dual purpose SP varieties and appropriate ratio of SP and other feed stuff to maximize livestock productivity in Kenya and Rwanda. Some key findings in Kenya show promising varieties for forage and dual purpose, and proportions of roots and vines for pigs’ diets. In conclusion, the need for on farm trial towards selecting agro-zones tolerant varieties and testing alternative SP silage recipe and packaging are keys aspects outlined for comprehensive study outcomes.
