some concerns about pelleting feed and raw materials chosen

There are some concerns about feeding a pelleted diet made by a pellet mill to pigs, specifically because corn is ground finer than it would be for mash feed. Pelleted diets ground to 450 microns or so can produce gastric ulcers in some pigs, Gaines says.
Be careful about using pelleted feed in health-challenged situations, adds Matt Kocher, associate director of Nutrition Technical Services for The Maschhoffs. “If you have a pig that is health-challenged and you are using a finer particle size in pelleted feed, there is a chance of increased incidence of ulcers. Furthermore, certain genetic lines may be more susceptible to gastric ulcers due to finer particle size,” he points out.
A second potential drawback is the need for increased feeder management with pelleted feed, says Gaines. Fines will occur as pellets travel through the mill and farm feed pellet making machine. As a result, it takes more focused daily feeder adjustments to avoid excessive feeder pan coverage and potentially more feed wastage, he warns.


Every feed production machine produces a broad range of products. These can include several different diets for a single species  or several different diets for many species . Broad product assortments require a vast number of available ingredients to meet the nutritional requirements of each specific diet. Since the number of possible ingredient combinations is endless and selection is normally based on least-cost formulations, demographics, or nutritional value, the formulations may change frequently. Therefore, proper attention must be taken to ensure high quality pellets are consistently produced. Ingredient grind (mean particle size) and formulation play a major role in producing high quality pellets.
