We can help you get started with a hay test. We have a hay corer that we lend out with a refundable $10 deposit.  We can assist with a submission to a lab and make a basic interpretation of a test report. If you are seeking to determine a feed ration you should consult with a nutrionist and work with your feed supplier. Consult a veterinarian for animal health needs.
