Pig Finishing System Welfare Comparison

Different pig finishing systems vary significantly in welfare outcomes, with enrichment provision, stocking density, and flooring type being key determinants.

Key Facts

Straw-based finishing systems have better welfare indicators than slatted floor systems
Pigs on slatted floors without bedding show more aggressive and stereotypic behaviour
Deep litter systems provide natural rooting behaviour and thermal comfort opportunities
Outdoor finishing on grass offers the highest welfare but is seasonal and weather-dependent
Consumer demand for higher welfare pork is driving system improvements in some markets

Welfare Considerations

Finishing system design is a primary determinant of welfare in the final 3-4 months of a pig's life. Straw and enriched systems consistently show better welfare indicators than bare slatted systems. The welfare cost of bare slatted systems affects millions of pigs daily and is a priority for welfare improvement.

What You Can Do

Choose pork from straw-based or outdoor finishing systems where possible
Support higher welfare certification schemes requiring enriched finishing environments
Advocate for minimum enrichment standards in pig finishing welfare legislation
