Work out stocking density instantly with clear inputs, formula shown and shareable results.
Expresses stocking density by head and by live weight per square metre, the measure most welfare codes regulate.
Stocking density
Animals per m2 = animals / area; density by weight (kg/m2) = animals per m2 x average live weight
Birds and animals grow, so a fixed head count becomes progressively more crowded; weight-based limits track the real space need.
EU rules cap most systems at 33 kg/m2, rising to 39 or 42 kg/m2 only with additional welfare conditions.
