Intensive animal farming

An agricultural system that raises many animals at high density using controlled environments and concentrated inputs to maximize production.

Concentrated animal feeding operation: A livestock facility where animals are confined and fed concentrated diets for much of production. This facility model concentrates animals, feed, and waste in one place.
Animal welfare: The physical and mental condition of animals, including their ability to experience positive and negative states. High stocking densities and restricted behavior make welfare a central concern.
Pastoralism: A livelihood and production system centered on raising livestock through managed movement and grazing. Pastoralism relies on mobile grazing rather than dense confinement and purchased feed.
Industrial poultry farming: Large-scale commercial production of poultry using specialized facilities and standardized processes. Poultry is a major sector where intensive housing and production cycles are widespread.
Animal welfare legislation: Laws that establish requirements or protections for the treatment and conditions of animals. Regulation determines which confinement and husbandry practices remain permissible.
Broiler industry: The commercial production system for chickens raised primarily for meat. Broiler production shows how specialized housing and rapid growth shape intensive farming.
Antimicrobial resistance: The ability of microbes to survive medicines that once killed them or stopped their growth. Antimicrobial use in livestock can contribute to selection for resistant microbes.
Extensive animal farming: Livestock production that uses relatively large areas of land and lower stocking densities. It contrasts with intensive farming in land use, stocking density, and input levels.
Industrial pig farming: Large-scale commercial production of pigs in specialized facilities. Pig production illustrates intensive breeding, housing, feeding, and manure management.
Antibiotic use in livestock: The administration of antibiotics to animals raised for food, for treatment or other permitted purposes. Policy debates weigh animal health needs against resistance risks from use.
