Effect of Feed Processing on Broiler Performance

چکیده
It is well recognized that feed represents the most significant cost of broiler production. Most production costs estimates range from 60-70% as being feed costs. Certainly, the major portion of feed costs is for the ingredients used. However, the cost of feed processing represents a significant portion of feed costs and likely gives the greatest opportunity for influencing broiler performance beyond nutritional adequacy. “Feed processing” and the costs associated with processing include a wide range of unit operations including receiving, grinding, proportioning, mixing, pelleting, loadout, and delivery. Nearly every one of these operations can have either a negative or positive influence on subsequent animal performance and can certainly influence the profitability of a poultry production company. The rate of gain for broilers has increased substantially during the last few decades. In 1960, a commercial broiler chicken attained a 2.2 Kg market weight by 12 weeks of age. Today’s broilers attain the same market weight in just 6 weeks (Havenstein et al., 1994). A similar trend has been noted for turkeys (Ferket, 2001). This remarkable improvement can be mainly attributed to improved genetics, however, tremendous improvements in nutrition have made it possible to take advantage of the genetic changes. Furthermore, our understanding of feed processing and feed delivery has allowed the economical implementation of many of the innovations in nutrition.

An experiment was conducted to compare the effect of corn-soybean meal finisher (29-42d) diets containing flaxseeds (rolled or extruded) on pellet quality, performance, n-3 fatty acids (FA) and oxidative stability of meat in broiler chickens. Seven pelleted diets were provided in a 3×2 factorial arrangement with three flaxseed levels (5, 10, and 15%) and two processing methods (rolled or extrud...
