Stocking Density
Definition
Stocking density is the number of animals (or their live weight) kept per unit of area — per hectare in grazing systems, per square metre in housed systems such as broiler chicken production. High densities increase disease pressure, heat stress, behavioural restriction and manure concentration beyond land's capacity to absorb nutrients; welfare schemes and regulations set maximum densities (for example EU organic rules and broiler directive limits), making density a primary audit and certification variable.

Overview
How it is used
The metric structures welfare certification (RSPCA Assured, organic standards), environmental permitting of intensive farms, ammonia and nitrate regulation, and antimicrobial resistance risk management.
Why it matters
Stocking density is the single number that best predicts whether animal farming is extensive stewardship or industrial confinement.
