African elephant height in feet

The quantity of food, energy, and specific nutrients, such as protein, required by an elephant may also be crudely derived from the allometric scaling factor of body mass or weight W0 75.

There are, however, difficulties in extrapolating this relationship all the way up (or down) to a herbivore as large as the elephant. Broadly, the elephant consumes less food and has lower nutrient requirements per unit of body weight compared to small herbivores (fig.

5.6).

Its consumption and requirements, however, are higher than predicted by simple allometric scaling. The observed daily food consumption of 1.5%-2.0% (dry matter) of an elephant's body weight is higher than that derived from regressions for herbivores.

Norman Owen-Smith uses a value of under 1% of body weight for African elephants; this is based on estimates by Richard Laws and team, who derived this from stomach fill and passage times. Field observations both in Africa and in Asia now clearly show these to be underestimates.
