Particle Size Analysis Information
The Swine Nutrition Lab can analyze grain or feed for particle size. We cannot analyze feed that has been pelleted. We prefer samples of ground grain rather than complete diets because the added fat frequently plugs the screens and may affect the results. Complete diet samples without added fat are acceptable. Please include your e-mail address for sending results.
Swine producers or feed manufacturers who would like their grain or feed analyzed for particle size, please send one pound of ground grain to:
