ABSTRACT
This study aimed to evaluate how the effects of substituting commercial concentrate (CC) with broiler by-product-based concentrate (BBBC) on the feed conversion ratio (FCR), weight difference (WD), and meat quality of Bali local pigs. A completely randomized design (CRD: 4×5) was used, with four treatments: T0 (ration with 24% CC and 0% BBBC), T1 (ration with 16% CC and 8% BBBC), T2 (ration with 8% CC and 16% BBBC), and T3 (ration with 0% CC and 24% BBBC). Each treatment was replicated five times, involving 20 Bali local pigs with an average body weight of 14.39 ± 0.79 kg. The research parameters included the feed conversion ratio (FCR), weight difference (WD) between final body weight (FBW) and slaughter weight (SW), and the meat quality of Bali local pig. The results showed that substituting CC with 8%, 16%, and 24% BBBC did not significantly affect FCR, WD, or meat quality parameters such as pH, water content, and ash content compared to the control group (P > 0.05). However, substitution with 16% and 24% BBBC significantly increased drip loss (T2:12,77% and T3: 11,93%), cooking loss (T2: 40,02% and T3: 40,12%), and meat fat content ( T2: 5 , 45 % and T 3 : 5 , 89 %) (P < 0.05) while decreasing water-holding capacity (T2: 32,98% and T3: 33,34%) and protein content (T2: 22,32% and T3: 22,12%) (P < 0.05). Substitution of CC with 24% BBBC can maintain FCR, WD values and pH, water content, ash content, but reduces the meat quality of Bali local pig. It is recommended to substitute with 24% BBBC to maintain FCR and WD, pH, ash content, water content and substitute with 8% BBBC to get optimal quality of Bali local pig meat.
