Evaluation of The Effect of Replacing Commercial Concentrate with Broiler Farm Waste Concentrate on Production Performance and Physical Quality of Bali Duck Meat

This study aims to evaluate the effect of partially substituting commercial concentrate (CC) with concentrate based on broiler chicken farm waste (CBB) on the production performance andphysical quality of bali duck meat. The study used a completely randomised design (CRD) with three treatments and five replicates (10). The treatments consisted of rations with 25% CC+0% CBB (T0), 12.5% CC+12.5% CBB (T1), and 0% CC+25% CBB (T2). The parameters observed included performance (weight gain, feed intake, feed conversion ratio) and physical quality of the meat (pH, water-holding capacity, cooking loss, and meat colour). The results showed that the use of CBB up to 25% (T2) had no significant effect (P>0.05) on the production performance of bali ducks (feed consumption, weight gain, FCR), or was the same as the control (P>0,05). Replacing CC with 12.5% and 25% CBB reducedthe physical qualityof the meat (P<0,05), but did not affect the colour of the bali duck meat (P>0,05). It is concludedthat replacing CC with 12.5%-25% CBB can sustainthe performance and colour of bali duck meat, but can reduce the physical quality of bali duck meat.
