| dc.description.abstract | This research was carried out to study the effect of fermentation ragi tape products (rice bran, pollard, soybean-hull, and cocoa-pod fermented) in diets on nutrients digestibility and growth performance of Bali drake aged 4-10 weeks. The design of experiment used a completely randomized design (CRD) with nine treatments and six replications. There were 10 birds in each replication with relative homogenuous body weight (359+12,75 g). The diets were formulated to 17% crude protein and 2900 kcal ME/kg as a control diet (A), diets with 15% rice bran (B), 15% rice bran fermented by 0,30% yeast culture (C); 15% pollard (D), 15% pollard fermented by 0,30% yeast culture (E), 15% soybeanhull (F), 15% soybean-hull fermented by 0,30% yeast culture (G), 15% cocoa-pod (H), and 15% cocoa-pod fermented by 0,30% yeast culture (I), repectively. Diets and drinking water were provided ad libitum. Variables were observed in this experiment are nutrient digestibility (protein, crude fibre, and energy), feed consumption, live weight gains (LWG)s, and feed conversion ratio (FCR). The results of this experiment showed that fermented rice bran, pollard, and soybean hull in diets, resvectively did not effect on feed consumption, but increasing LWGs compared with unfermented feeds. The nutrient digestibility (protein, crude fibre, and metabolizable energy) and FCR however decreased. Birds offered fermentation ragi tape products (treatment C, E, G, and I) had higher (P<0,05) nutrient digestibility and growth performance compared with those of control and unfermented products. It is concluded that inclusion of fermentation ragi tape products (rice bran, pollard, soybean-hull, and cocoa-pod fermented) in diets could increase nutrient digestibility and growth performance of Bali drake aged 4-10 weeks. | id |
