I work on two dairy farms and this is just disgusting. Why in the hell would you treat the animals like this?? Any good farmer knows that the more comfortable, relaxed and happy the cows are, the less likely they are to get sick and will produce more milk. The only time we ever use a pitchfork is when in close quarters with the bulls and even so, they are only ever used if the bull is question is not having a very good day if you know what I mean. Calves can be incredibly frustrating, but I mean, they're just like children. They don't know any better. And to beat them upside the head because they won't stand still...??
Working with cows (animals in general, really, but most pertinently cows) is terribly frustrating at times and it's so easy to want to take it out on them, but this only makes them less and less receptive to the task you want them to accomplish. Cows are not as stupid as people say. I think they are incredibly intelligent and incredibly stubborn - bad combination.
