狼网||英汉对照：了解狼（之十一）狼吃多少

Getting enough to eat is a full-time job for a wolf. When wolves catch and kill a large mammal, they will gorge and then rest while the food is being rapidly digested. They will generally consume all but the hide, some of the large bones and skull and the rumen (stomach contents of ungulates) of their prey. Gray wolves can survive on about 2 1/2 pounds of food per wolf per day, but they require about five to seven pounds per wolf per day to reproduce successfully. The most a large gray wolf can eat at one time is about 22.5 pounds. Adult wolves can survive for days and even weeks without food if they have to. Growing pups, however, require regular nourishment in order to be strong enough to travel and hunt with the adults by the autumn of their first year. Wolves often rely on food they have cached after a successful hunt in order to see them through lean times.

Red wolves may eat 2 to 5 pounds of food per day when prey is abundant. Because they are smaller than gray wolves, they can consume less at one time than their larger cousins. But like all wolves, eating for red wolves is a matter of “feast” followed by “famine.”
