Mixed farming--that being raising both crops and livestock and using those crops to feed livestock--is the most draining of resources than either raising livestock for meat/eggs/dairy and raising crops for grain and vegetables. When comparing raising livestock for meat in the most sustainable or conservational sense to raising plants for grains, fruits or vegetables, livestock raised in such a manner are less of a drain on the Earth's resources than raising crops. Pasturing livestock is more sustainable and environmentall friendly than raising crops because almost no fossil fuels, pesticides nor fertilizers (though not in the purest sense) are needed to raise these animals, plus the ground is not turned over repeatedly to allow for the growth of monoculture crops. Greater carbon sequestration is had with ranching and raising livestock on pasture than even the most conservational tillage practices for raising crops.
It depends on what kind of livestock you are referring to. Each type of livestock have their own level of expenses and costs incorporated in raising them. For instance, it can be more expensive to raise and breed horses than it is raising and breeding chickens.
