Zoos, wildlife parks, and institutional animal care facilities manage diverse species with varying nutritional requirements. Year-round fresh forage supply is a consistent operational challenge — particularly in winter months or in climates where fresh green feed is not reliably available. Specialist species often require specific fresh plant material that cannot be reliably sourced from commercial suppliers at consistent quality. Managing multiple species with divergent feed requirements adds complexity to sourcing, and supply disruptions can create significant welfare and operational problems.
