[QUOTE="2/B or not 2/B, post: 957104, member: 7233"] I love Biopryn too, but had an interesting experience with it this year. Tested a group of cows 30 days after AI. Retested a few times after that to make sure everyone stayed bred and that those who were open got bred to clean up. Anyhow, one of the cows that tested open for AI and bred later calved exactly on the AI due date. She had a bull calf that weighed over 100 lbs. so I really don't think he was premature. Anyhow, I think the results for opens are supposed to be almost 100% accurate. She must have slipped through on a very minute margin of error. It certainly wouldn't keep me from using it again in the future. I do like to retest a couple of times though. A cow that tests bred at 30 days can slip a calf and fall behind the herd without notice if you don't see that she comes back into heat and gets bred again later. [/QUOTE]
