Summary
This review synthesises current understanding of the multiple adaptive strategies—physiological, metabolic, and behavioural—that enable yaks to function effectively in the extreme conditions of the Asian highlands, including high altitude, cold temperatures, and sparse forage availability. The authors, including leading yak research specialists, likely discuss mechanisms of hypoxic adaptation, energy metabolism, and breed-specific traits that confer resilience. Such knowledge is relevant for understanding how indigenous livestock systems maintain productivity under environmental constraints.
Regional applicability
Direct applicability to UK farming is limited, as UK climate and geography differ substantially from high-altitude Asian conditions. However, the adaptive mechanisms identified may inform broader understanding of livestock resilience to climate variability and extensive grazing systems.
Key measures
Likely adaptive traits including respiratory capacity, metabolic rate, body composition, digestive efficiency, and environmental stress tolerance mechanisms
Outcomes reported
The study examined the morphological, physiological, and metabolic adaptive mechanisms that allow yaks to thrive in the Asian highland regions, likely including traits related to oxygen utilisation, thermoregulation, and forage digestion efficiency.
