Zoo Nutrition Science and Animal Welfare

Appropriate nutrition is fundamental to zoo animal welfare, yet wild dietary needs are often complex, requiring specialist expertise and ongoing research to meet adequately.

Key Facts

Nutritional deficiencies can cause metabolic bone disease, reproductive failure, and immune suppression
Many zoos now employ specialist zoo nutritionists
Invertebrate feeders require diverse prey items to avoid nutritional gaps
Enriched feeding methods improve both nutrition and psychological welfare
Research into wild diets informs zoo nutrition programmes

Welfare Considerations

Poor nutrition in captive animals causes suffering through metabolic disease, reproductive problems, and immune deficiency. Zoo nutrition science has advanced significantly, but resourcing specialist expertise across all facilities remains a challenge.
