Intensive animal farming or
industrial livestock production, also called
factory farming, is a modern form of
intensive farming that refers to the keeping of
livestock, such as cattle, poultry (including in "
battery cages") and fish at higher stocking densities than is usually the case with other forms of animal agriculture—a practice typical in
industrial farming by
agribusinesses. The main products of this industry are
meat,
milk and
eggs for human consumption. There are issues regarding whether factory farming is sustainable and
ethical.
