This research used 41 growing backyard piglets (11.47 ± 1.2 kg BW) fed for 22 d and assigned at random to three treatment (T) groups, respectively (T1 to T3) with three repetitions. The proportion of commercial concentrate (CC) to kitchen waste (DW) was: T1, 100:0; T2, 50:50 and T3, 0:100. Diets contained: T1, 17.3, 13.6 and 16.3% CP and 3,321, 3,526 and 4,011 McCall/kg of ME, respectively. Weight gain, carcass characteristics, minerals and metabolites in blood serum were evaluated. The weight gain, slaughter weight, hot and cold carcass weight, hot and cold carcass yield, rib eye area and back fat thickness were not affected by DW (P> 0.05). The cuts of leg shoulder and rib were not affected by treatment (P> 0.05) for dry matter, ash and crude protein content. The increase in DW reduced ether extract content of leg and rib (P <0.05) but not in shoulder (P> 0.05). The concentration of Ca decreased with DW inclusion (P <0.05). No treatment effect was observed in blood metabolites (P> 0.05). It is concluded that feeding with DW the backyard growing pig do not affect growth performance or quality of meat.
