Advantages of pellet feed on nutrition value and performance of meat-type chicken

The poultry feed industry is pretty much active in a lot of countries and it is achieved market acceptance. The final products are supposed to meet certain specifications to fulfill the nutritional need of animals at different life periods. The final product for poultry is shipped in the form of pelleted feed for the convenience of consumption. Pelleting is the most prevalent heat treatment in the production of poultry feed. The objective of pelleting is to agglomerate smaller feed particles into larger particles as pellets to enhance the economics of production by increasing the feed intake, and thus growth performance and feed efficiency. However, due to the heat, moisture and mechanical pressure applied during conditioning and pelleting, some chemical and physical alterations occur that may have beneficial or detrimental effects on feed components, gastrointestinal development and subsequent bird performance. It is well accepted that offering feed to broilers in pellet form enhances the economics of production by enhancing growth performance and feed efficiency. Although it is generally believed that pelleting improves nutrient digestibility, there is little published evidence to support this belief. On the contrary, some reports suggest that pelleting may decrease nutrient utilisation under some conditions. Limited published data available on the effect of pelleting on nutrient utilisation is reviewed in this paper. Pelleting is the most popular thermal processing technique in poultry industry. Birds fed pelleted diets have greater feed intake and weight gain, and better feed conversion ratio .
