Factors that Affect Pellet Quality

The feed given to broilers is manufactured at significant cost into a pelleted form. Pellets reduce broiler production costs by increasing feed intake and growth rate while reducing feed. Pellet quality is expressed using a method called the Pellet Durability Index (PDI). Also poor Physical Pellet Quality (PPQ) produces more fine particles during feed transportation from feed mill to poultry house feed lines but of using of fat inclusion like the mixer-added vegetable oils had a negative effect (–۴۰ value) on PPQ. Also there are element that affect pellet quality such as type and level of feed ingredient inclusion, especially distiller's dried grains with soluble (DDGS) and mixer-added fat, and feed milling process. Some factor like increasing the conditioning temperature, when feed formulation allowed, also reduced energy consumption and increased throughput at the pellet mill. Also particle size is the factor that causes the least influence on pellet quality. Reducing particle size increases particle surface area relative to its volume, thereby increasing the number of contact sites among particles.
