Joyce, go to www.hayexchange.com There are a few
listings of places to send your hay for an analysis. You can call your local
co-op extensive service for a lab near you or ask the people you get your hay
from where they get it tested. It can cost anywhere from $20-60+ to have your
hay tested. I have had mine done at Holmes Laboratory. phone #330-893-2933 in
