For every 100 kilograms of food made for humans from crops, 37 kilograms byproducts unsuitable for direct human consumption are generated. [9] Many countries then repurpose these human-inedible crop byproducts as livestock feed for cattle.[10] Raising animals for human consumption accounts for approximately 40% of total agricultural output in industrialized nations. Moreover, the efficiency of meat production varies depending on the specific production system, as well as the type of feed. It may require anywhere from 0.9 and 7.9 kilograms of grain to produce 1 kilogram of beef, between 0.1 to 4.3 kilograms of grain to produce 1 kilogram of pork, and 0 to 3.5 kilograms of grains to produce 1 kilogram of chicken.[11][12]
