It got me thinking - Do we have 'Caged Cows' or 'Battery Cows'?

The World Society for the Protection of Animals (WSPA) website states: "A free range dairy cow will stay with her calf, quickly developing a strong bond. A cow will feed its calf for six to eight months, and they will experience the outdoors together."

WSPA also states: "A factory farmed dairy cow is usually separated from her calf shortly after birth, causing great distress. Her milk is reserved for humans – high-energy feed will force her to produce around ten times more milk than she would naturally. Stress causes painful udder infections and lameness, made worse by manure covered concrete floors."

I've seen the farm factories for chooks, but I've never seen or heard of such behaviour for milking cows.

Can anyone throw some light on the topic?
