Please explain sheep and any other animal really, that can become “cast” – isn’t falling down just a normal part of life? How is it that they can’t get back up themselves and will die from what I think of as a basic fact of life?
In: Biology
Others have already mentioned selective breeding, but it should also be noted that a sheep getting cast is still a pretty unusual occurrence, and happens for a lot of the same reasons that a human might fall down and be unable to get back up – injury, heavy pregnancy, elderly or infirm, trapped by heavy clothing, caught in a hole… Most sheep never get cast, and the repeat offenders probably have some underlying cause. Accidents happen, and some individuals aren’t able to recover without help. That’s not really a species-dependent thing.
