Being continuous voracious feeders of wide variety of plants and mineral rich soils, elephants eat about 200 to 270 kg of food per day and release about 100 to 130 kg dung per day in the form of balls of size 100 to 150 mm in diameter, 70 to 180 mm in length and 1 to 2 kg in weight. Fifty to sixty percent of foods come out as dung being undigested.
