Theist is right.
Lord Krishna always tries to make us understand that giving our service to Cows is what is needed to prime and the service that Cows provide us is secondary... that also we are allowed to drink the milk only after all calves have been fully fed.
Consuming the milk without considering how our sweet mothers are being treated is blindness.

As humans, we all suffer at times in our lives, why dont we ask ourselves about compassion for animals, who are very similar to us? Why cant we understand their pain?

I was born a vegetarian and I think its a relationship of mother and child, if we drink milk of cow, we have to love and respect cow as our mother. Cow also has gestation period of 9 months like humans. How beautiful her eyes are!

But unfortunately, people dont realise the suffering of cows in the factory farms. How would people feel if their mother or themselves or someone they dearly love was treated like that?

Dairy cows have to be repeatedly impregnated to keep up their milk production. What is to be done with all the male calves which are born as a result of those pregnancies? The answer is that they are kept in tiny veal cages so that they can not move during their entire short and miserable lives - keeping their muscles soft so that the veal is tender. I would love to get some milk from cows that I know are protected ... however to just go to the market and buy some milk - organic or not - is to be complicit in veal production. That is simply a fact. If you have verified knowledge of a milk producer that never supports the veal or beef industry then please let me know and I will support them. I don't think Shree Vishnu wants me to offer Him the milk of tortured cows any more than He wants me to offer Him the veal which is a direct byproduct of that milk production. Cow torture is not cow protection.
