Ok, who uses them for milk test? I am really trying to figure this stuff out. I have a person to test my herd. He is going to get certified to test. I talked to Langston and they sent me a package of thingy's to put the milk in and paperwork to fill out. Oh, and a DVD but I haven't been able to watch it yet. A couple Q's: How long after a doe freshens do I need to start testing them? Do I have to milk twice a day to do the test? Some of my does I only milk once a day until the kids are weaned.... Height?!?! I don't have one of those official measurement sticks.
