That all depends on what you're testing it for: Are you testing it for moisture, internal temperature or for its feed value?
The former two simply involve sticking a long (around 3 ft long) probe with a digital reader attached that usually enables you to see both moisture and temperature measurements into the bale, hitting right into the core (centre), then waiting for the meter to give you the results.
The latter, however, involves taking a sample, usually from as close to the middle of the bale as possible (never take from the outer layer as that will skew the results), and sending it, by mail, to a lab specially designed to test such feeds. An example is the Cumberland Valley Analytical Services; the techs working here will test your hay based on what you want your hay tested for. The methods for testing for various nutrients are lengthy and complex, too long to mention in this answer. It is highly recommend you visit the related link below to see the various types of tests that can be run for your hay sample and how they are achieved for yourself.
i feed haygrazer to my small herd of cows/steers/calves as a sole ration, and they do well on it. i have the nitrates tested before i feed it, but they really like the hay.
There is really no such thing as 'too ripe' with hay provided it has been cured and baled correctly. The only time you should avoid feeding hay is if it has been rained on or baled with a high moisture content. You can find out the quality of your hay by having it tested in a lab for nutritional quality and moisture content. You should also check hay before feeding it to horses, looking for mold, excessive dust and foreign bodies such as trash , dead animals, or insects. (Blister beetles are sometimes baled into Alfalfa hay.) If the hay checks out okay, you can feed it the same day it was baled.
Third crop or third cut hay can be safe for horses depending on where it was grown, it's level of maturity at cutting, and how well it was fertilized / maintained. You should always have hay tested for it's nutrient and sugar content before feeding it to any animal.

No, a bushel of hay is not equal to one bale of hay. There is approximately twenty bales of hay in one bushel or string bale or hay.
There is no such thing. Hay is hay regardless if it's a part of a hay pile, part of a hay bale, or anything like that.
Either alfalfa hay or grass hay but if would prefere alfalfa hay
