Peel meals as feed ingredients in poultry diets: Chemical composition, dietary recommendations and prospects.

The increase demand for poultry products has had direct effect on the supply and price of feed. This has increased research interest into the potential of locally available, less competed and low cost materials as feed ingredients. Several peels from roots/tubers and fruits have been evaluated in poultry diets but recommendations have not been consistent. High fibre, low nutrient density and likely presence of antinutritional factors limit the efficient utilisation of peel meal by poultry. Plant cultivar, age, agronomic practices, method of peel processing, breed and age of poultry all affect the inclusion level of peel meal in poultry diets. The increase interest in breeding crops for low antinutrients, knowledge in processing technologies and availability of several additives such as enzyme products, amino acids and antinutrients binding agents in the feed market could improve the usefulness of peel meal in on-farm poultry rations. This study reviews the potential of selected root/tuber and fruit peels as feed ingredients for poultry with regards their composition, dietary recommendation and prospects.
