PENINGKATAN KECERNAAN LIMBAH TEMPE DENGAN MIKROBA SELULOLITIK DAN RESPONS PEMBERIANNYA PADA ITIK

This research was conducted to study the use of fermented soybean hull by celulolitic culture to improve performance of bali duckling at 6-12 weeks of age. The research used a completely randomized design (CRD) with three treatments and six replicates. There were four birds six weeks aged in each replicate with relative homogenous body weight. The experimental diets for the experiment period (up to six weeks of age) were formulated to 16% crude protein and 2900 kcal ME/kg as a control diets (A), diets with 15% soybean hull (B), and diets with 15% soybean hull fermented with 0,20% celulolitic culture (C), respectively. Experimental diets and drinking water were provided with ad libitum during the experimental period. The variables observed were feed consumption, final body weight, body weight gains, and feed conversion ratio. The results showed that use of 15% fermented soybean hull in diets increased feed consumption, final body weight, body weight gains, and feed conversion ratio compared to control and unfermented feed. It was concluded that fermented soybean hull by cellulolitics microbes increased six weeks of age bali duckling performances
