This review aims to provide a comprehensive synthesis of recent findings on environmental enrichment for breeding does and growing rabbits, focusing on the main categories of enrichment including social, sensory, physical, occupational and nutritional types, and their documented effects on animal welfare, integrating behavioural, physiological, and performance outcomes.
