What are the odds of a COW, not a heifer, having twins that are the opposite sex? And she only takes care of the first born (hiefer) of the two.[/b][/u]

Since the affects of the mixing of the fluids between the bull and heifer that causes freemartins can run the gambit from the most obvious, an enlarged and bristle brush looking vulva to complete reproductive organs but insufficient hormones to maintain a pregnancy, either a live calf on the ground (2 years minimum) or a bloodtest (2 weeks) why feed an animal for a couple of years that will be (probably) butchered anyway. I know, a run on sentence. I just couldn't figure out a logical place to break it and start a new one.

do the heifer got pregnant? I recall 9 years ago a heifer of our twins (opposite sex) got pregnant and it was because we never wean her and the rancher just liked her that we kept it, but since then the vet check all twin heifers at 12 months of age before slaughter (freezer beef) and all of them had infantile uterus.Arancher":17d1ot3w said:I'm not sure of percentages nationally but in my case i've only had two sets and hope never to have another. One always seems to do better than the other. They were of both sexes and in both cases the heifer out weghted the bull calf at birth and had to ween the bull early .
