[QUOTE="Quigly, post: 1202350, member: 21929"] A good vet can preg them at 32 days without an ultrasound and be accurate, though 35 is a safer cut off for a lot of vets that don't do a large volume or early pregging. There are synchronization protocols designed around an early preg check, a lot of them involve giving lut at time of preg check if you are sleeving them and therefore have an instant answer. Early embryonic loss can be a challenge with blood testing, if an animal aborts, a vet will generally be able to call her open faster then she will become open on the blood test, takes some time for the protein tested for to clear the cows blood stream. It's a bigger deal in dairy cattle due to the large degree of early pregnancy loss. Also, there is no detection of twins with the blood test and sexing isn't possible, though you would have to wait til 60 days or so to have a vet sex them so it isn't as relevant when discussing early pregnancy detection. Blood testing should prevent any fetal loss due to trauma from palpating, but that is very rare with an experienced palpator, especially when using ultrasound. Also, there are pregnancy tests that use a milk sample, but I don't think they can be utilized until 36 days bred or somewhere around that that time frame. [/QUOTE]
