As the world's population grows, the National Research Council estimates that the supply of food required to adequately meet human nutritional needs over the next 40 years will be equal to the amount of food previously produced throughout the entire history of humankind. To meet this demand, animal scientists must develop new technologies to increase productive efficiency (that is, the yield of milk or meat per unit of feed), produce leaner animals and provide increased economic return on investment to producers. During the past decade, scientists have developed many new agricultural biotechnologies that meet these goals.
