Male cattle used to be used for the plow. Again its a modern thing to just kill them. Male chickens are another matter as there was not much use for more than one and they tended to fight. Sows again your talking the modern factory farming thing. Yeah I was trying to cut out one animal at a time and my goal was only eggs and cheese but I have given up given how much I hear from folks its all the same and just as bad. Its pretty hard to stay motivated honestly and I simply have not been able to eat vegan meal after meal. I used to think the vampires shows were the "good" vampire fell off the wagon and drained humans was dumb but my experiences cutting out meat makes me think if I was a vampire I would likely be drinking humans.
