Horse hay testing is a good idea. It's the only way to be sure of its actual nutrient content. And knowing the nutrient content is important so you can be sure your horse is eating an adequate diet.
The better the hay, the less grain you'll need...which can mean significant savings! Learn how to spot quality hay here.
You'll need a hay corer to take samples. If you don't have one, contact your county or state agricultural extension and borrow one. Take samples from as many bales as possible. They may offer recommendations on a testing lab in your area.
We recommend Equi-Analytical Labs for tests. They will provide instructions on taking, packing and shipping your samples. Common tests include the NSC (non-structural carbohydrate) or 'sugar and starch' test to determine the hay's potential to increase the risk of metabolic disorders and the Rider Test of basic nutrients.
Hay Warning: Be sure you are not purchasing or using hay from a source that spreads uncomposted horse manure on their fields. Strongyle (bloodworm) larvae can survive up to eight months in hay harvested from fields fertilized with infected horse manure.
