[QUOTE="SBMF 2015, post: 1768586, member: 39695"] We Bio-PRYN blood tests on the spring calving cows. We did 120 back in September. Fairly happy with the results. I typically find that the cows that come back "open" just aren't bred far enough along for the test to register. If a tight calving window is important, then cull those cows even if they are short bred. Otherwise wait a couple months and repreg the open ones. I've been using the blood tests for seven years. Never had an issue. [/QUOTE]
