No idea about Dairy cattle but would of though they had an easy life apart from the male's
I agree with you but a lot of the times the guidelines are just not followed

Dairy factory cows are artificially inseminated at an early age then the calf is taken away after 1 or 2 days so they can produce milk for almost a year.
They are pumped full antibiotics, and fed unnatural high-protein so they can produce more milk.
They are always in pain and have udder infections
