How can cows produce milk all year round?

Question

As any mammal, cows produce milk when they give birth to a calf and until it eats solid food.

How are cows able to produce milk? Shouldn’t they stop producing it when they are pregnant and/or they have weaned a calf?

Answer 1

We have selectively bred them to produce milk longer and in higher quantity than the calf requires, but the answer to your question is that cows get forcefully impregnated and the calves taken away.
