THE ENERGY FACTOR IN RELATION TO FOOD INTAKE: EXPERIMENTS ON THE DOG

Abstract

Feeding experiments with dogs using artificial diets adequate in all known respects show that under uniform conditions of experimentation the animals so regulate their food intake as to maintain a constant intake of energy per uuit of body surface area. This phenomenon is called "caloric adjustment." A linear relationship exists between the body length and the logarithm of the calories per hr. adjusted to by the animals. On the basis of this relationship, a table useful for prediction purposes in feeding dogs was constructed.
