Analab is devoted to providing our clients with outstanding customer service and world-class results. We want to help our clients achieve their best. We work with samples from all over the world and give each client the same individual attention. We want people to have the information they need to make informed decisions. We work with farmers, veterinarians, schools, agriservice personnel, and other organizations to provide the analytical services that they need.

Submitting Forage Samples

Make sure that you are getting a good representation of your forage when collecting a sample. The best way to do this is to collect several small samples to make one big one. The sample you submit represents several tons of feed, so you want a good cross-section. If you send in one that represents the worst of your lot, you may end up overfeeding and increasing your costs. If it is only the best, then your livestock may not get the nutrients they need.  It is vital that you get a good representation for your forage sample.

Time is important when shipping your samples, so we recommend that you use a USPS flat rate Priority Mail box or UPS. Both methods have tracking information and are able to tell you when delivery dates will be. If shipping from outside the continental United States, you may want to look into other methods.

We recommend shipping your forage sample in a quart-sized resealable bag. The list below will give you an idea of the size of sample you may need, depending on the type of forage.

  • Corn Silage: 250g/9 oz
  • Grain/Grain Byproducts: 250g/9 oz
  • Hay: 250g/9 oz
  • Haylage: 250g/9 oz
  • Mixed Rations: 250g/9 oz


Sampling Procedures

An analysis is only as good as the sample submitted. Taking a good representative sample of your feed is the first and most critical step of the analysis process. However, it is often this step that is the most taken for granted. Following good sampling procedures will help insure that your test results will truly reflect the nutrient composition of your sample and will be useful in developing your feeding program.

The key to submitting a good sample is to collect several subsamples to form a composite. Remember, the sample that you submit for analysis is going to represent several tons of feed. You want to be sure that it represents a good cross-section of the feed, not just one bale or bunker pile.
