Description
Rakhmad Perkasa Harahap and colleagues tested in 2026 whether chitosan, a compound made from shrimp shells, can preserve mixed livestock rations and improve how rumen microbes handle them. Rations were stored for 30 days with no additive, raw shell, chitin, or chitosan, under conditions with and without air. Afterward the team measured storage losses and ran laboratory rumen fermentations.
Storage without air preserved feed better overall, and chitosan gave the strongest protection, with the least dry matter loss and the best appearance and smell scores. Chitosan rations also digested best in the laboratory and produced the least methane. The authors present shrimp shell waste as a useful feed additive that turns a disposal problem into a benefit.
