Morphological Study on the Coat Hair in Golden Takin

The study investigates the coat hair structure of the golden takin, a member of the Bovidae family, comparing it to cattle hair. Using morphological analysis and WAXD measurements, researchers found that the takin's overcoat hair features a continuous thick medullated tissue, while the undercoat hair is finely crimped and lacks medullated tissue. These characteristics help maintain body temperature in harsh winter conditions. The overcoat hair's longitudinal section shows a dendritic framework with air spaces or wax-like granules. WAXD measurements of summer coat hairs revealed α-keratin peaks, with additional weak peaks corresponding to the β′ crystal form of fats. The study concludes that these hair structures are adaptations to the takin's environment.
