Royal antelope
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
Elephants in Thailand
Elephants are herbivores, consuming ripe bananas, leaves, bamboo, tree bark, and other fruits. Eating occupies 18 hours of an elephant's day. They eat 100-200 kilograms of food per day. A cow (female) will eat 5.6 percent of her body weight per day. A bull (male) will eat 4.8 percent. Thus a 3,000 kilogram cow will consume 168 kg per day, a 4,000 kg bull 192 kg per day. As elephants can digest only 40 percent of their daily intake, the result is dung amounting to 50–60 kg daily. As elephants will not eat in unclean surroundings fouled by dung, their instinct is to roam to a new area.
