An Iowa cow gave birth this week to a rare ox, but that calf has died. Scientists cloned a rare Asian Gaur (gow-er) and implanted it in the womb of an Angus cow. The calf, named Noah, was born Monday at Trans Ova Genetics in Sioux Center. It died Wednesday of dysentery. Scientists say the calf’s death was unrelated to its cloning. Noah was the first animal to gestate in the womb of another species and survive through the late stages of fetal development. Five other cows that became pregnant in the same way spontaneously aborted their ox babies. Scientists hope to have more inter-species births to help bring more endangered species into the world.
