In my opnion focusing on ethical farming is more promising (under an utilitarian perspective). If the focus is to reduce suffering and exploitation of animals the best action is to ban the most cruel practices by law pushing stricter ethical standards. People will continue to eat meat everywhere they can afford it (maybe less, maybe more) veganism is not going to change that.
