Forage and Pasture
There are a lot of ways you can weigh your hay. The following are a few options. One may be more convenient for you than another.
The best technique to sample your horses hay is to use a mechanical coring probe made specifically for this purpose. Probes are able to sample a cross-section of the bale (end to center) and the serrated tip allows collection of both coarse and fine particles. When using a hay probe is not an option, the next best method is hand pulling from the center of multiple bales.
