A total of eight ([Landrace &times; Yorkshire] &times; Duroc) barrows with an initial body weight (BW) of 33.06 ± 1.16 kg were placed in metabolism crates. The dietary treatments were structured using a 4 &times; 2 factorial design, which included two factors: four diet types (i.e., corn-based diet, CON; corn-plain bread meal (PBM)-based diet, PBMD; corn-sweet bread meal (SBM)-based diet, SBMD; and corn-biscuit meal (BM)-based diet (BMD) with or without 0.1% multi-enzyme supplementation). In this study, the concentrations of DE and ME were 4075 and 3981 kcal/kg dry matter (DM) in two-source bakery meals (i.e., PBM and SBM) and 4153 and 4075 kcal/kg DM in BM. The DE and ME (on a DM basis) in the bakery meals (i.e., PBM and SBM) and BM were significantly higher (p < 0.05) than in corn. However, there was no significant difference (p > 0.05) in the ATTD of DM, GE, and N among the dietary treatments, multi-enzyme, and their interaction. In summary, the bakery meals and biscuit meals investigated in this study have the potential to partially replace corn. Further research is necessary to ascertain the effects of multi-enzyme supplements on bakery meals and biscuit meals.
