It's not unheard of...
'
a dairy cow can be given reproductive hormones and prescribed antibiotics by a vet to ensure she is kept in a condition to produce an unnatural amount of milk. Under normal circumstances, she would generally only have a maximum of two litres of milk in her udder at any one time, but rapacious farmers may force her to carry 20 litres or more. Her udder becomes so heavy that it makes her lame and she often develops an agonising infection called mastitis. The strain this puts on her body means she is exhausted by the age of five. Soon, her milk yield will no longer be considered profitable. Or she might simply collapse under the agony of it all. Either way, she will be dragged off by a tractor, squeezed into a cramped truck, and driven to the slaughterhouse, to be killed and turned into burgers or baby food. Her throat slit after five sad and torturous years – under natural circumstances she could have lived to 25.'
