Pigs have long been the most common animal for meat in many parts of the
world. The reason for this is economic. The pig produces meat more efficiently than
any other animal. For every 100 pounds of food that it eats, a pig produces 20 pounds
of meat. In comparison, beef cattle produce
a. more than 30 pounds of meat per 100 pounds of food.
b. twice as much meat per 100 pounds of food.
c. only about 7 pounds of meat per 100 pounds of food.
d. nearly double the amount of meat per 100 pounds of food.
