Pig Wean-to-Finish Nutrition Welfare

Nutritional management from weaning through finishing profoundly affects pig welfare, growth, and immune health across the production cycle.

Key Facts

Weaning at 3 to 4 weeks causes significant digestive stress as pigs transition from milk
Post-weaning diarrhea is a leading cause of mortality and suffering in young pigs
High-quality protein sources and gradual dietary transitions reduce post-weaning disease
Zinc oxide has been used to control post-weaning diarrhea but is now restricted in the EU
Probiotic and prebiotic supplementation shows promise as an antibiotic-free alternative

Welfare Considerations

Pigs experiencing post-weaning digestive stress suffer from diarrhea, dehydration, and reduced immune function. Nutritional strategies that support gut health at weaning prevent considerable suffering.

What You Can Do

Support pork from farms with documented weaning nutrition protocols
Advocate for investment in antibiotic-free alternatives to zinc oxide
Choose pork certified by schemes requiring weaning age and nutrition standards
