In swine production, efficiency of utilization of nutrients is imperative. By embracing advances in processing techniques(i.e., fine grinding, pelleting, steam flaking, roasting, extrusion and expanding) nutrient utilization of feeds turfs have greatly improved. Grinding is by far the most commonly used process with reduction of particle size, Expander, like extruders, are high-temperature and pressure-short-term processor. The purpose of using an expander is to improve pellet quality. Also, expanding of dietary ingredients indicates improvements in growth performance and nutrient digestibility. Because feed cost are easily the greatest economic input into swine production, maximizing nutrient utilization is an area that will continue to receive much attention. Therefore, much attention will continue to be placed on feed processing techniques that will give consistent improvements in animal performance and nutrient digestibility.
