[QUOTE="Lucky_P, post: 848159, member: 12607"] My understanding, from other discussions I've seen on it, is that it's just a progesterone test - one test really only tells you if the cow has a functional CL - not necessarily if she's pregnant. You'd have to do 5 tests, on 5 consecutive days to determine that the cow is bred - one negative in that group of 5 means: OPEN. If it's $5 a pop, and you've gotta do 5 of 'em to be sure...it ain't all that cheap. From one of the company's recent email blasts: # Recommend 5 test for animal where we do not have enough knowledge of their insemination date after 23rd day post insemination, the test should continue for 5 consecutive days and one negative result confirm that the animal is OPEN (negative pregnancy). BioPryn requires a blood test, but measures a placenta-derived compound, so a positive is definitive. It's the way I'd go if I were doing a non-palpation pregnancy test. [/QUOTE]
