Hay testing

Mailing materials and probes, or hay samplers, for forage testing by commercial labs are available as a convenience to our clients. Probes/samplers are recommended to get a proper sample.

Forage testing is one of the cheapest and best investments a livestock producer when it comes to nutrition and their herd. The test will cost around $20.00 and will give you the information needed to develop a supplement to meet the livestock’s needs. Like testing anything, useful results only come from a good sampling process. Always use a hay probe to and take a core sample for your test rather than a simple “grab and go” where you pick a handful from a few bales and call it good. The core sample should be taken from the round side of a round bale or the end of a square bale, going straight toward the center so you get a good representation of the entire bale. You will need to probe somewhere between 10 and 20 bales and have a sample that weighs about a pound to get a good representative sample. Sort hay into “lots” by hay type and harvest window and test each individual lot.
