Meet the super cow

I'm not sure what my reaction about this video is. It is one more of those instances where humans have used their scientific know how to manipulate the nature to their advantage. Selective breeding is used to produce these hugely muscular cows and bulls, weighing sometimes up to 1 tonne (ton). There is no cruelty to the animals involved here but even so, I couldn't help but cringe a bit looking at these bovines.
