Abstract: Two experiments were conducted to evaluate fermented fish meal as a new animal protein source on N balance, Apparent Total Tract (ATTD) and ileal AA Digestibility (AID) in weanling pigs. In Exp. 1: total 40 [(LandracexYorkshire)xDuroc] barrows were randomly allocated 4 treatments (10 pigs per treatment) for a 12 days metabolic trial. The dietary treatments of Exp. 1 and 2 were SFM (small fish), LFM (small fish fermented with L. acidophilus), AMFM (Anchovy-Mackerel Fish Meal, LT®) and MFM (Mackerel Fish Meal, BIO-CP®). N concentrations in the feces were found to be greater in pigs fed SFM than pigs fed AMFM (p<0.05). The AID of Arg, Val and Cys was greater in pigs fed LFM than in SFM (p<0.05). The AID of all AA except Met, Tyr was greater in pigs fed MFM than in SFM (p<0.05). In Exp. 2: 16 [(LandracexYorkshire)xDuroc] barrows were surgically equipped with a T-cannula in the distal ileum. They were allotted 4 treatments (4 pigs per treatment) for evaluating the AID. The AID of His, Thr and total AA was greater in pigs fed AMFM and MFM than in SFM (p<0.05). The AID of Val was greater in pigs fed MFM than in SFM (p<0.05). The AID of Asp and Ser was greater in pigs fed MFM than in SFM (p<0.05). The AID of Glu was greater in pigs fed AMFM and MFM than in SFM (p<0.05). The AID of dispensable and total AA was greater in pigs fed LFM, AMFM and MFM than in SFM (p<0.05).
