Pig Stocking Density Welfare Standards

Stocking density is one of the most significant determinants of pig welfare, affecting aggression, disease transmission, and ability to express natural behaviours.

Key Facts

EU law requires minimum 0.65m2 per pig (60-85kg) for fattening pigs
Higher welfare certification schemes require 25-100% more space than legal minimum
High density increases tail biting, respiratory disease, and competitive stress
Pigs at lower densities show more play behaviour and positive welfare indicators
Overcrowding is associated with higher mortality and culling rates

Welfare Considerations

Stocking density is a master variable in pig welfare - too high and multiple welfare problems emerge simultaneously. Space allowance determines whether pigs can express natural behaviours, avoid aggression, and access resources without competition. Minimum legal standards in many countries are welfare inadequate.

What You Can Do

Support higher welfare pork certification schemes with better stocking standards
Advocate for meaningful minimum space requirements in pig welfare legislation
Choose pork products where producers publish welfare metrics including space allowance
