The optimum performance of duck farm can be achieved by providing them with good quality rations. Rations with good digestibility will increase the productivity due to large amount intake of nutrients. Chitosan is type of animal fibre which assisted the growth of useful microbes in digestive system. Addition of chitosan in cattle rations will improve the ecologic of duck digestive system to be more conducive. The aimed of the research was to evaluate rations digestibility with the addition of chitosan. The research was used completely randomized design with 4 treatments and 5 repetitions. Each repetition consists of 2 ducks. The treatments are R0 stands for rations without chitosan and R1-R3 with addition of chitosan 0.5%, 2% and 2.5% respectively. Parameter measured were dried matter, organic matter and crude protein digestibility. Data processing was conducted by using SAS Windows 16. Result showed chitosan addition at 0.5% and 2.5% gave dried matter and crude protein digestibility does not higher than control (P>0.05) while chitosan addition at 2% gave result lower than control. Organic matter digestibility displays balanced in value. Abstrak (Indonesian)Optimalitas peforma ternak itik dapat tercapai jika mendapat ransum berkualitas. Ransum berkualitas dengan kecernaan yang baik akan meningkatkan produktivitas ternak. Kitosan adalah jenis serat hewan yang bermanfaat untuk memicu kehidupan mikroba menguntungkan dalam saluran cerna. Jika diberikan dalam ransum akan menyebabkan ekologis saluran pencernaan ternak itik menjadi lebih kondusif. Tujuan penelitian adalah mengkaji kecernaan ransum dengan pemberian kitosan. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Masing-masing ulangan terdiri dari 2 ekor itik sebagai satuan percobaan. Perlakuan adalah R0 = 0% kitosan, R1 = 0,5% kitosan, R2 = 2% kitosan dan R3 = 2,5% kitosan. Peubah yang diukur adalah kecernaan Bahan Kering, Bahan Organik dan Protein kasar. Data diolah menggunakan program SAS Windows 16. Hasil penelitian menunjukkan bahwa pemberian kitosan 0,5% dan 2,5% memberikan rataan kecernaan Bahan Kering dan Protein Kasar tidak lebih tinggi dari kontrol (P>0,05), sedangkan dosis 2% kitosan nyata lebih rendah dari kontrol, Kecernaan Bahan Organik menunjukkan angka berimbang.Kata Kunci: Kitosan, kecernaan bahan kering, bahan organic, protein kasar, ransum Sahara et al.
