Your email address will not be published. While this makes raw feathers light, durable, and unable to stretch (unlike hair), it also makes feather keratin undigestible (digestibility < 5%) (Papadopoulos, 1985; Kornillowicz-Kowalska et al., 2011). Again, protein is the most expensive nutrient in livestock feed. Res., 14 (3): 542-547, Seo, S. H.; Jung, B. Y.; Lee, M. K.; Lee, B. H.; Paik, I. K., 2009.
