Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh penggantian gamal dengan kaliandra (Calliandra calothyrsus) pada ransum terhadap degradasi rumen secara in-vitro. Penelitian mengunakan rancangan acak
lengkap (RAL) yang terdiri dari lima perlakuan dan tiga kali ulangan sehingga terdapat 15 unit percobaan. Adapun kelima perlakuan tersebut adalah: perlakuan A (ransum basal + 20% gamal), B (ransum basal + 15
% gamal + 5% kaliandra), C (ransum basal + 10% gamal + 10% kaliandra ), D (ransum basal + 5% gamal + 15 % kaliandra ), dan E (ransum basal + 20% kaliandra ). Peubah yang diamati adalah: degradasi ransum
dalam cairan rumen in-vitro (kecernaan bahan kering [KCBK], kecernaan bahan organik [KCBK]), degradasi ransum dalam pepsin in-vitro (KCBK, KCBO), kadar ammonia, kadar VFA (Vollatyl Fatty Acid) dan pH cairan
rumen in-vitro. Hasil penelitian menunjukkan bahwa penggantian daun gamal dengan daun kaliandra sampai tingkat 20% dalam ransum, dapat menurunkan kecernaan bahan kering dan organik dalam rumen, tetapi
sebaliknya meningkatkan kecernaan bahan kering dan organik dalam pepsin in-vitro. Disamping itu dapat menurunkan kadar N-NH3 dan VFA, tetapi meningkatkan pH cairan rumen in-vitro. Dapat disimpulkan
bahwa tanin kaliandra dapat dipakai sebagai agen proteksi dari degradasi mikroorganisme rumen in-vitro di dalam ransum, dan penggunaan kaliandra sampai 20% dalam ransum sebagai protek protein ransum dapat
menghasilkan kecernaan bahan kering dan bahan organik pepsin in-vitro tertinggi.
