Technological revolution in the field of agriculture has tremendously generated huge quantities of waste causing environmental pollution. The agriculture wastes can be categorised into different categories, such as crop waste and residues; cereal by-products; sugar beet pulp, starch and confectionary industry by-products; oil cereal industry by-products; grain and legumes by-products. It was found that the agro-co-products could be recommended in the poultry diet with low-cost advantages alternative to conventional ingredients. Despite of the high fibre content and low nutrient availability that limit the utilisation of these by-products by poultry, the source of by-product, processing method/enzyme supplementation and animal factors found affect the utilisation of agroindustrial by-products by poultry. If we could produce valuable products from agriculture wastes by-products through new technological and scientific applications, these by-products could be converted into products with a higher nutritive value than the main feedstuffs. Therefore, the present paper provides a brief discussion on the utilisation of some agro-processing wastes as a source of nutrients in poultry diets.
