Reply to comment by Various_Succotash_79 in ELI5 Are cows constantly producing milk? by ms_myco

Assuming the consumer didn’t care at all, would it be possible to treat cows with hormones to keep them going without having to make a baby?

Hmm, rBST is used to boost milk production but I don't know if it can be used to bypass the need for pregnancy/birth altogether. It's probably cheaper to just let them have a calf, plus they need female calves to keep the dairy going.
