I admit it, I have only been to two different dairy farms. A good friend worked at them.
It was NOTHING like this video. This video is the exception not the rule. An example of the bad egg of the industry.
The cows at both farms I visited walked into the parlor (almost always in the same order which I thought was so cool) on their own. They walked to their spots and stood quietly to be cleaned and hooked up.
Yes, sometimes a little direction was required (as is with our horses) but no pitchforks or pry bars were used.
The individuals in that video most certainly have an anger management issue. Beating a restrained animal for no obvious reason shows that they truly have a screw missing some where in that head of theirs.
Happy content cows produce more milk. Those are not happy and content cows.
