PLF's major purpose is to make livestock production more economically, socially, and environmentally sustainable, which may be accomplished by observation, behaviour interpretation, and, if possible, individual management of animals. Additionally, using PLF to assist management practises may result in a reduction in farm environmental impact like reduction of greenhouse gas (GHG) and ammonia (NH3) emissions in the air, nitrates and antibiotic pollution in water bodies, phosphorus, antibiotics, and heavy metals in the soil.
