The objective of this study was to set up a minimal disease Muscovy duck herd and establish the embryonic eggs and duckling supply system for research, development and production of waterfowl vaccine. The minimal disease Muscovy duck herd (L305) has been selected from L302G13 (white Muscovy duck LRI 1) for 10 generations and were raised in a high bio-security duck house. The antibody of goose parvovirus (GPV), Muscovy parvovirus (MDPV) and duck hepatitis virus (DHV) was monitored when the ducks were 12, 24 and 40weeks by serum neutralization (SN) and virus neutralization (VN). After improving the bio-security measures and intensive disinfection, the antibody titer of monitored diseases had decreased. These embryonic eggs can produce over one million doses of live parvovirus vaccines.
