Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan pollard sebagai aditif terhadap komposisi kimia, kecernaan, fermentasi in vitro, dan nilai pakan silase limbah sayur kubis. Bahan yang digunakan adalah limbah sayur kubis dan pollard. Penelitian menggunakan empat perlakuan tingkat penambahan pollard: 0% (T0), 3% (T1), 6% (T2), dan 9% (T3) dari total bahan segar kubis. Parameter yang diamati meliputi kandungan bahan kering (BK), bahan organik (BO), protein kasar (PK), serat deterjen netral (NDF), serat deterjen asam (ADF), pH silase, kecernaan in vitro BK dan BO, konsentrasi total VFA dan NH₃, serta nilai kualitas silase seperti Fleight point dan Relative Feed Value (RFV). Hasil menunjukkan bahwa penambahan pollard secara signifikan (P<0,05) meningkatkan BK, BO, PK, kecernaan in vitro, serta nilai VFA, NH₃, Fleight point, dan RFV, namun menurunkan kandungan NDF dan ADF. Penggunaan pollard hingga 9% menghasilkan silase dengan kualitas fermentasi dan nilai nutrisi terbaik. Dapat disimpulkan bahwa pollard merupakan aditif potensial untuk meningkatkan kualitas silase limbah sayur kubis sebagai pakan ternak ruminansia.
