[QUOTE="simme, post: 1768598, member: 40418"] Be aware of the timing for Biopyrn. Test a month or more after breeding or after the bulls are pulled from the pasture. And 3 months or more after their previous calf was born. The test looks for a specific protein that is produced by the placenta. If the cow has recently aborted, that protein can still be present in the blood and can result in a false positive. The test is supposed to be 97% accurate overall and 99% accurate in detecting open cows (1% testing false open). Not 100% accurate, but neither is palpation. Aggressive palpation "might" result in an abortion, which should not occur with the blood test. Compare the convenience between palpation and blood test. If using a vet or other palpation person for preg testing, their schedule has to coordinated with your schedule. Biopyrn testing is pretty much your schedule. Fairly simple and low cost. Use a new needle for each sample. Use red top tubes for the samples. Get those from your vet or order from the Biopyrn lab. [/QUOTE]
