Introduction: Livestock-Raising (01:44)
Humans rely on animals for protein and employed domestication to satisfy that demand. Meat, eggs and milk come from livestock farming; the practice drives large divisions of the economy.
Humans began as nomadic hunter-gatherers; agriculture and the domestication of animals appeared in Mesopotamia during the Neolithic revolution. Increased food production led to a rise in human population and the emergence of towns; tools, laws, and codes were developed for tracking and trading livestock. Farming was a primary source of income for most families; automated practices are common today.
Cattle and Chicken Farming (02:06)
Farmers raise cows for milk and beef; India claims the largest bovine population. Poultry farming includes ducks, turkey, geese and other fowl—chickens are consumed globally. Workers harvest meat, eggs, and feathers for consumption and textiles.
Pig Farming (01:23)
Pigs are clean, intelligent, omnivorous animals that are efficient at nutrition conversion. They are profitable to keep and yield meat, fat, leather, and hair.
Other Kinds of Farming (02:43)
Horses, donkeys, and asses are ideal beasts of burden and provide transportation, food, and recreation. Goats provide meat and cheese, as do wool producing sheep. Sudan claims the largest population of camels, bred for milk, skin, labor, and transportation.
Farming Techniques (04:36)
In undeveloped countries, small, family farms are common; intensive farming occurs in industrialized nations. Herding and shepherding methods are potentially ecologically sound. Industrial farming is profit driven and automated; animals are kept in tight quarters and receive production increasing hormones.
Current Situation of Livestock Farming (03:28)
Humans must sustainably raise food, but intensive farming is environmentally problematic. Genetic engineering modifies animals for production and nutritional purposes. Humans consume vast amounts of plant and animal life; unjust distribution, resource exploitation, and escalating populations prompt the use of modified species and vegetable proteins.
