Summary
# Editorial Summary Domestic livestock adoption fundamentally transformed the Mongolian Altai region, with proteomic analysis of dairy proteins from Bronze Age through Iron Age archaeological sites revealing a phased subsistence shift that preceded major social reorganisation. Early Bronze Age communities initially integrated ruminant livestock into their diet, establishing the economic foundation for sustained population growth and eventually supporting the monumental construction and structured settlements that characterised later periods. Notably, horse dairying emerged around 1350 cal BCE in tandem with pronounced social complexity—evidenced by population expansion, formal cemetery systems, and large-scale monuments—yet this transition built upon centuries of accumulated pastoral investment in ruminant herds rather than representing an independent driver. These findings suggest that whilst the introduction of domesticated ruminants and horses triggered immediate dietary changes, the development of stratified societies resulted from long-term economic intensification, wherein pastoral reliability enabled demographic expansion and resource accumulation. For equine professionals working with modern pastoral systems, this research underscores how horse integration into established livestock economies leverages pre-existing management expertise and social infrastructure, offering historical perspective on how equine productivity interfaces with broader agricultural sustainability and social organisation.

Practical Takeaways
- •This archaeological/historical study has no direct application to modern equine practice
- •Understanding the historical role of horses in pastoral societies provides cultural context but not clinical or management guidance
- •The timing of horse domestication and use in dairying systems is archaeological interest only
Key Findings
- •Proteomic evidence shows shifts in dairy consumption in the Altai Mountains from Early Bronze to Late Iron Age
- •Ruminant livestock adoption at dawn of Bronze Age preceded social complexity by approximately 1350 years
- •Horse dairying evidence (~1350 cal BCE) coincided with pronounced social changes and monumental constructions
- •Long-term economic dependence on ruminant livestock fueled demographic and social transformations in western Mongolia
