Nutritional Welfare in Livestock: Meeting Species-Specific Needs

Meeting the species-specific nutritional needs of farm animals is fundamental to welfare, with deficiency causing preventable disease and suffering.

Key Facts

Selenium deficiency causes white muscle disease in lambs and calves
Copper deficiency impairs immune function and causes coat and growth problems in cattle
Laying hens require high calcium intakes to sustain egg production without bone loss
Sows in late gestation have dramatically increased nutritional requirements not always met
Precision nutrition matched to individual animal needs reduces both deficiency and toxicity risks

Welfare Considerations

Nutritional welfare goes beyond providing adequate calories to ensuring that all essential nutrients are available in appropriate quantities and forms. Species-specific requirements that differ from other species must be known and met. Deficiency diseases including selenium deficiency, copper deficiency, and calcium depletion cause genuine suffering that is entirely preventable with appropriate nutritional management. Investment in nutritional welfare creates both welfare and productivity benefits.
