No, it isn't. That's a pretty rotten practice too. Any taking very young animals off their mothers for our own benefits I don't like, though I know it's standard practice in many dairy operations.
I sometimes think we separate ourselves too much from animals and treat them on a whim, like playthings or machines, 'commodities' rather than other, not so different, sentient beings. I don't have a problem with respectful farming or pet keeping - but respectful and necessary it should be.
