How to Take Samples—Particle Sizing

Sample size required: 1/2 gallon

Fresh samples should be taken from the feed bunk before livestock have a chance to eat or sort the feed. Sampling should not be done directly from the storage area as mixing and distribution equipment may further reduce particle size and should be accounted for when evaluating the diet. Sub samples obtained from different parts of the bunk, mixed together in a large pail, will result in a more representative sample. Care should be taken not to shake the composite samples as the smaller particles will settle to the bottom of the pail. Fill a 1/2 gallon plastic bag with the composite sample (bag does not have to be overfilled). Bag should be sealed so that it is airtight. Sample should be stored in a cool place until sent to the lab.
