Scanning Electron Microscopy and Morphometric Analysis of Dromedary Hair with SEM-EDX in Relation to Age

This study examined the morphological features of dromedary camel hair in relation to age using samples from 30 camels divided into three age groups. The analysis revealed that the medulla patterns and structures varied with age, with the medulla index increasing from 0.3% in the youngest group (G1) to 0.77% in the oldest group (G3). The shaft width increased from G1 to G2 but decreased significantly in G3. The cortex and cuticle widths also varied with age, being larger in younger camels. The cuticle scale shapes evolved from wavy in G1 to long and rectangular in G3. SEM-EDX analysis identified various elements, with sulfur levels peaking in G2. Overall, the study concluded that the hair structure and mineral content, especially carbon and nitrogen, change as camels age.
