Do some reading about milk production. Rape is actually part of the process.
Perhaps the most unpleasant fact to consider about cows’ milk destined for human consumption is that it almost certainly required a heifer’s forced impregnation. Female cows are strapped to a rack (common slang often refers to the device as a “rape rack”) and inseminated with semen stored in a massive syringe. There are 9 million dairy cows in the United States. Nearly every one of them suffers immensely from the results of this experience.
