Sweet potato (Ipomoea batatas (L.) Lam) as feed ingredient in poultry diets

Abstract

The purpose of this review is to highlight the potential of sweet potato as a feed ingredient for poultry diets. 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.
