Saiga antelope calving aggregations represent both a remarkable natural phenomenon and a critical welfare vulnerability, requiring seasonal protection from disturbance and disease monitoring.
Saiga calving aggregations are functionally the most vulnerable period in the annual cycle for this species. The synchronization of thousands of births in a small area creates dramatic wildlife spectacle but also concentrates individual welfare risks. Disturbance during calving can cause females to abandon calves or scatter prematurely, leaving vulnerable neonates exposed to predation and cold. Disease outbreaks during calving aggregations spread with devastating speed, as the 2015 event demonstrated catastrophically. Seasonal protection of calving grounds from human disturbance and the deployment of veterinary rapid response teams during the critical window are the most welfare-effective specific interventions available. The welfare benefit of successful calving season protection cascades through the entire population for the following year.
