    • Abstract:
      The seminal plasma and sperm of fresh and stored poultry semen were analyzed for the presence of eight peptide hydrolase enzymes. Five enzymes: carboxypeptidase A, carboxypeptidase B, chymotrypsin, glycylglycylglycine hydrolase and pepsin were not present in either plasma or sperm. An aminopeptidase-like and a cathepsin-like activity were found in seminal plasma and sperm while a trypsin-like activity was found in sperm only. There was a significant difference between full sib groups with respect to aminopeptidase-like activity in fresh and stored plasma, while storage for 24 hours resulted in a significant increase in trypsin-like activity of sperm. The aminopeptidase-like activity of fresh sperm was positively correlated with duration and percent fertility of fresh semen, while neither cathepsin-like activity nor trypsin-like activity were correlated with fertility of fresh or stored semen except for a positive correlation between the cathepsin-like activity of fresh plasma and percent fertility of fresh semen.
