Peptidase activities against Ala3, Ala4 and Phe3 were increased (P <0.05) by salinomycin, whereas activities against Ala5 and Phe4 were unchanged and that against Gly-Arg-MNA was decreased (P <0.05). In the presence of salinomycin, the main products of peptide hydrolysis were single amino acids, whereas dipeptides were formed in samples from control vessels.
