Pig Vitamin Mineral Nutrition Welfare

Vitamin and mineral deficiencies in pigs cause welfare problems including bone deformities, immune suppression, and skin conditions, with targeted supplementation preventing common deficiency diseases.

Key Facts

Vitamin D deficiency in indoor pigs causes rickets and bone weakness without supplementation
Zinc deficiency causes parakeratosis, a painful skin condition, in zinc-deficient diets
Iron deficiency in neonatal piglets causes anaemia requiring preventive supplementation
Selenium deficiency causes muscular dystrophy in severe cases
Balanced commercial diets prevent most deficiencies but errors in formulation cause welfare problems

Welfare Considerations

Nutritional deficiencies cause preventable suffering including bone pain, skin disease, and anaemia. Ensuring balanced diets and targeted supplementation prevents these entirely avoidable conditions.

What You Can Do

Work with a nutritionist to verify mineral and vitamin content of pig diets
Supplement neonatal piglets with iron by day 3 of life to prevent anaemia
Monitor for signs of deficiency including skin lesions, lameness, and poor growth
Audit feed quality regularly to detect formulation errors before they cause welfare problems
