What is it about?
This review discusses in general the metabolisable energy value of this feed resource when compared to maize and its impact on the performance of broilers and layers fed at various inclusion rates. Trypsin inhibitors are the major anti-nutritive factor present in sweet potato; however these are eliminated with heat treatment. Nutrient profile and feeding value of different types of sweet potato meal such as potato root meal, potato peel waste, potato leaf meal and cooked potato meal are discussed. Based on feed cost, this could be an effective alternative feed ingredient in the diets of broilers and layers.

Why is it important?
Based on feed cost, Sweat Potato Meal could be an effective alternative feed ingredient in poultry diets, especially where it is locally grown
Perspectives
One of the major problems facing the poultry industry today is the high cost of feeds resulting from a shortage of high energy grains such as maize. An increase in the price of grains and the cost of producing poultry meat and eggs has resulted in a decreased ability of some of the world's population to purchase and consume chicken meat. To compensate for this change, alternative feed ingredients need to be identified. One promising alternative is sweet potato. Because, Maize and sweet potato have comparable metabolisable energy values of 14.5 and 14.8 MJ/kg, respectively. Sweet potato can replace maize in the diet of broilers by 17-27% and 30-40% for starter and finisher broiler chickens respectively.
