When the animal is used by man for food

When the animal is used by man for food, one class of foods stored away in the animal's body produces muscle; another produces fat, heat, and energy. The food furnished by the slaughter of animals seems necessary to the full development of man. It is true that the flesh of an animal will not support human life so long as would the grain that the animal ate while growing, but it is also true that animal food does not require so much of man's force to digest it. Hence the use of meat forces a part of man's life-struggle on the lower animal.

When men feed grain to stock, the animals receive in return power and food in their most available forms. Men strengthen the animal that they themselves may be strengthened. One of the great questions, then, for the stock-grower's consideration is how to make the least amount of food fed to animals produce the most power and flesh.
