Conservation breeding programmes in zoos manage genetic diversity for reintroduction - welfare of individuals in these programmes requires careful ethical consideration.
Conservation breeding welfare involves genuine ethical complexity. Transferring genetically valuable individuals between facilities causes transport and social disruption welfare costs. Surplus animals - those born but not needed for genetic management - face uncertain welfare outcomes. Pre-release conditioning for reintroduction involves exposing animals to welfare stressors to prepare them for survival in the wild. These welfare costs must be weighed against conservation benefits. Transparent evaluation of whether conservation breeding provides genuine population-level benefit sufficient to justify individual welfare costs is needed. Species where captive welfare is irreconcilably poor should not be kept even for conservation purposes.
