Tujuan: Penelitian ini dilakukan untuk mengevaluasi pengaruh penambahan kitosan asal kulit udang pada dosis yang berbeda ke dalam ransum basal terhadap emisi gas metan dan fermentasi rumen secara in vitro.

Metode: Perlakuan terdiri dari: P0 (ransum basal), P1 (ransum basal + kitosan 2% BK), dan P2 (ransum basal + kitosan 4% BK). Variabel yang diukur adalah kinetika produksi gas, produksi metan dinyatakan dalam produksi metan per unit bahan kering sampel dan produksi metan per unit bahan organik yang dicerna, kecernaan bahan kering (KCBK), kecernaan bahan organik (KCBO), volatile fatty acid (VFA), dan amonia (NH3).

Hasil: Hasil penelitian menunjukkan bahwa penambahan kitosan 2% dan 4% BK dapat menurunkan secara signifikan (P<0,05) total produksi gas, laju produksi gas dan produksi metan. Namun demikian penambahan kitosan asal kulit udang pada tidak berbeda nyata terhadap peubah KCBK, KCBO, VFA, dan NH3 (P>0,05).

Kesimpulan: Dapat disimpulkan bahwa kitosan dalam pakan bermanfaat dalam menurunkanemisi gas metan secara in vitro.
