SO I've got a possible puzzler. Here goes. AI'd a cow last summer and vet pregchecked her 31 days later. (I think she used ultrasound, as we usually wait til more like 40 days minimum). Cow was open, so we did another round of timed AI and she "took." That would have her due June 14. However, she is as big, or bigger, than the cow that "took" on the first AI and is due May 3. The June 14-calver also is showing other very early signs--just a bit floppy in back, and maybe just slightly more noticeable bag (she does not usually have a big bag anyway).
I thought that perhaps the vet missed the call on the first time since it was so early (ie, she was actually pregnant), but even if so, wouldn't the AI meds (GnRh, Lute, CIDR) have likely caused her to miscarry? So then, is it more likely she is bigger than expected because she has twins? We have not had twins yet. (She's had 3 singletons).
Related question: would the ultrasound have shown the twins that early?
I may run this past the vet as well but thought I'd see what y'all think....She is not our biggest cow. The one I'd be LEAST likely to want twins from. Of course....
