[QUOTE="Princess Pooper, post: 8190742, member: 971"] Only reliable time to test for neospora is either at the time of abortion (or ideally with some of the aborted foetus) OR - if she gets in calf again, then in the last couple of months before calving. We first found our neospora problem when we ran a sweeper bull with the heifers years ago and we would have some calving about 4 months after we thought they were due (we didn't PD). They had been getting pregnant to AI but then aborting and then the bull would get them pregnant again. Not all calves will abort, some are born but are then carriers of the protozoan. These can be tested when born if have only had dam's milk. I would be talking to vet about what to screen for regarding other things like BVD, depending on your herd health status. If you do swing any round then if they get in calf, test for neospora when you dry them off as it should show up then.

We still don't PD the heifers but we PD all cows through NMR, at 44 days+ (can be done earlier but we might just have missed a heat, so leave it until after 2 heats). Very pleased with results, just doesn't tell you when she will calf or if she is carrying twins. We PD manually anything that we are a bit suspicious might have lost her calf later on even if we haven't seen her bulling. [/QUOTE]
