| Outline of Final Research Achievements |
I investigated the effect of the variants of antimicrobial proteins on poultry production in this study. A polymorphism of the lysozyme gene, which was related to antimicrobial activity and hatchability, did not significantly affect the body weight at 6th weeks old, average egg weight and survival rate in Japanese quail. I tried to identify causal mutations of three variants of the chicken ovotransferrin gene. An Asp500Asn mutation was identified as a causal mutation between B and C variants. The B and C variants purified from egg white were not significantly different in antibacterial activity.
