Summary
This 2025 study evaluates the nutritional quality of alas pasture vegetation in Yakutia, a subarctic region of Russia with extreme seasonal variation. The research characterises the energy density and chemical composition of native forage species, contributing regional data on pasture nutritional value under permafrost-influenced conditions. As a location-specific agronomic assessment, the findings support livestock feeding decisions in high-latitude pastoral systems.
UK applicability
Limited direct applicability; Yakutia's extreme continental climate, permafrost dynamics, and native vegetation differ substantially from UK grasslands. However, the methodological approach to characterising native pasture quality may inform research on forage composition under challenging environmental conditions.
Key measures
Energy value (metabolisable energy or digestible energy), crude protein, crude fibre, ash content, and mineral/micronutrient composition of native pasture forage species
Outcomes reported
The study assessed the energy content and chemical composition (as suggested by title) of alas pasture forage species grown under Yakutia's extreme continental conditions. Analysis likely included protein, fibre, mineral and vitamin profiles relevant to livestock feed value.
