SASHA Brief 2013: Exploiting sweetpotato as an animal feed in East Africa

East Africa has the highest per capita consumption of livestock products among all the regions in sub-Saharan Africa (SSA). High population pressure has led to increased competition for land between food grains and feed resources. The problem is compounded by a lack of quality feed year-round, with major feed shortages during the dry season that severely affect the lactation cycle in dairy animals. Quality feed concentrates are too expensive for many farmers, thus they draw heavily on locally available feed ingredients. Sweetpotato offers great potential as an animal feed in sub-Saharan Africa (SSA) but its potential use as a feed or dual purpose (food and feed) crop has not been fully exploited. This brief explores the effort of researchers in exploiting sweetpotato for use as animal feed. The major breakthrough is the development of an improved silage tube and testing of the resultant sweetpotato silage on growing pigs with small-scale farmers in Kenya.
