Can someone take me through the process of how you would go about testing them to make sure they don't have any harmful diseases that could be passed on in their milk? From what I hear Brucellosis is one to test for, but from what I hear, that it is also very very uncommon in the U.S. I think TB is another to test for. Are these tests all done by getting their blood tested, or can you test the milk directly, and if so, where do I send them? As you can see, I'm kind of oblivious on this whole thing. Can someone take me through the process of what to test for, and how to test it? I believe my goats to be pretty healthy goats, but I want to test them regularly just as a precaution, and in case I decide to sell their milk. Thanks.
