Pig Welfare and Stocking Density Evidence 2026

Stocking density has significant effects on pig welfare, with new 2026 research clarifying minimum space requirements for good welfare outcomes.

Key Facts

EU minimum stocking density for finishing pigs is 0.65 sq m per 100 kg bodyweight
Studies show welfare indicators improve significantly at 1.0 sq m or more per pig
Overcrowded pigs show more aggression, higher injury rates, and lower growth rates
Lying time decreases markedly when pigs cannot lie simultaneously in natural positions
UK Pig Welfare Code recommends 0.75-1.0 sq m as good practice for finishing pigs

Welfare Considerations

Stocking density is one of the most significant determinants of pig welfare. Evidence supports raising minimum standards beyond current legal minimums.
