Livestock
The word livestock first appeared in print between 1650 and 1660. It combined the words live and stock to describe animals kept for human use. In earlier centuries, people used cattle and livestock interchangeably. The meaning shifted over the nineteenth century to distinguish broad animal categories from specific bovines. Federal legislation in the United States defines the term differently depending on the program. The Livestock Mandatory Reporting Act of 1999 limits livestock to cattle, swine, and sheep. A 1988 disaster assistance law expanded the definition to include goats, poultry, equine animals, fish, and other designated species. Horses count as livestock under US federal rules. The USDA classifies pork, veal, beef, and lamb as red meat. Poultry and fish fall outside this category because the FDA regulates them instead. Deadstock refers to animals that died before slaughter due to illness or disease. Selling such meat remains illegal in many countries including Canada.
Animal rearing began during the transition from hunter-gatherer lifestyles to settled farming communities. Dogs appear in Europe and the Far East approximately fifteen thousand years ago. Goats and sheep were domesticated through multiple events between eleven thousand and five thousand years ago in Southwest Asia. Pigs entered domestication by eight thousand five hundred BC in the Near East and six thousand BC in China. Horse domestication dates to around four thousand BC. Cattle have been kept since roughly ten thousand five hundred years ago. Chickens and other poultry may have been domesticated around seven thousand BC. Modern farmed animals differ radically from their wild ancestors in behavior and physiology. Many cannot survive in natural environments today. Their breeding and living conditions remain entirely controlled by humans over millennia of selective pressure.
Ranching systems operate across large areas of public and private land in the Western United States. Similar cattle stations exist in South America, Australia, and regions with low rainfall. Sheep graze untended on mountain fells in the uplands of the United Kingdom during spring months. They move to lower altitudes late in the year with supplementary feeding provided in winter. In rural African communities, hens live for months without being fed yet still produce one or two eggs weekly. Dairy cows sometimes stay in zero-grazing conditions where all forage is brought directly to them. Beef cattle occupy high-density feedlots while pigs reside in climate-controlled buildings that never see outdoor light. Poultry reared as laying birds remain inside barns under strict lighting schedules. Semi-intensive family farms bridge these extremes by allowing grazing outside most of the year. Silage or hay covers periods when grass stops growing. Farmers purchase fertilizer, feed, and other inputs from external sources to maintain production levels.
Global livestock production reached an estimated value of 883 billion dollars in 2013 using constant 2005, 2006 dollar figures. This figure includes downstream industries like abattoirs, milk processors, refrigerated transport, wholesalers, retailers, tanneries, and food services. Upstream sectors encompass feed producers, equipment manufacturers, seed companies, and vaccine makers. Veterinary consultants, nutritionists, and shearers provide associated services. Livestock manure maintains grazing land fertility and fertilizes cropland due to its nutrient-rich content. Some regions use animal waste directly as fuel or indirectly generate methane for heating and electricity. Three hundred million draft animals provided energy between twenty-five and sixty-four percent of cultivation energy globally in irrigated systems during 1997. The International Crops Research Institute for the Semi-Arid Tropics helped Zimbabwe farmers maximize their herds. Ranching on national forest land in New Mexico connects families to ancestral lands and cultural heritage. Profit ranks low among motivations for ranchers who prioritize family tradition and a desired way of life. They historically accept lower returns to preserve open space and community values.
Animal husbandry accounts for roughly twenty to thirty-three percent of global fresh water usage. Livestock and their feed occupy about one-third of Earth's ice-free land. Agriculture contributes to species extinction, desertification, and habitat destruction through deforestation and conversion of land for grazing. Animal husbandry causes up to ninety-one percent of deforestation in the Amazon region. The Intergovernmental Panel on Climate Change linked agricultural emission increases from the 1970s to the 2000s directly to livestock population growth. Cattle produce approximately seventy-nine million tons of methane daily. Enteric methane from livestock represents thirty percent of total planetary methane emissions. Humans relate thirty-four percent of all nitrous oxide emissions to livestock through feed production and manure management. Best production practices could reduce these emissions by thirty percent according to estimates. The IPCC reported agriculture accounted for ten to twelve percent of global anthropogenic greenhouse gas emissions in 2005 and again in 2010.
Good husbandry, proper feeding, and hygiene maximize economic benefits through improved animal health. Farmers treat sick animals with veterinary medicines under government guidelines requiring treatment records. Classical swine fever affects specific populations while foot-and-mouth disease impacts all cloven-hoofed animals. Governments impose import and export regulations along with quarantine restrictions when diseases become serious. Vaccines exist against certain conditions but antibiotics remain widely used where appropriate. Routine addition of antibiotics to compound foodstuffs once promoted growth but now risks antibiotic resistance. Sea lice infestations increasingly affect farmed salmon in Scotland. Reducing parasite burdens boosts productivity and profitability. Livestock diseases are expected to worsen as climate change increases temperature and precipitation variability. The Special Report on Climate Change and Land highlights this growing threat to herd stability and farmer livelihoods globally.
Seventy-four percent of worldwide livestock are raised in factory farms characterized by dense confinement. Consumers typically oppose intensive farming methods when surveyed directly. A majority remain unaware of routine controversial practices like break trimming or separation of calves from mothers. Gas chamber slaughter procedures also escape public awareness despite their prevalence. Three quarters of US adults believe the animal products they consume come from humanely treated sources. Believing livestock farming is cruel became the most common reason for adopting veganism or vegetarianism throughout the 2010s. Animal ethics examines moral implications of using animals for consumption and human responsibilities toward them. Debates address whether current practices align with societal values regarding welfare and sustainability. Public opinion continues shifting as information about industrial agriculture spreads through media channels and educational campaigns.
