Not much. This is mostly about animal milk production. Cows have to be pregnant in order to produce milk for their calves. But dairy farmers artificially inseminate (rape) cows and steal the milk meant for the calves.
Male calves and cows who get old are sent to slaughter houses for meat, and other products like leather.
So, it does have to do a little about eating and not eating meat, but it is mostly about animal milk.
You had to do research for that?
