January 2010 in “Animal” In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.
February 2026 in “Small Ruminant Research” This study found that specific genetic variations in the IRF2BP2 gene influence fleece structure in sheep, with one variant completely determining coat type and another significantly modifying fiber characteristics, providing valuable insights for improving fleece quality through selective breeding.
