So much for those happy cows.
That happy cow stuff is propaganda. I visited California in May and observed several dairies. They are actually cow prisons. The cows are restricted to a fairly large fenced area in which they ate and crapped and gave milk. The ground is churned mix of mud and crap surrounding large feeding sheds....... deplorable.
Out side the fence are large, very large, immense, hay storage areas.
I was of the opinion the cows ate hay, not corn. The hay storage and visible hay in the sheds gave no indication of corn.
The cows that escaped from Wisconsin escaped into slavery of deplorable conditions
