Abstract: In order to prevent the gosling plague and the goose paramyxovirus disease, the JLDA strain of the gosling plague and the strain JLSY of the goose paramyxovirus were selected to produce the oil-emulsion inactivated vaccine against gosling plaque, goose paramyxovirus disease. Applied the PALL condensing technic to condense the virus, the vaccine was ensured that the antigen content was enough and the proportion was equilibrium. The 10^# white oil was selected as the adjuvant and the proportion of the oil and water was 1∶1, the ropy degree of the vaccine was low. The results showed that the immune effect was not lower than that of the corresponding vaccine, and indicated that the goose parvovirus and the goose paramyxovirus could not be interfered.The results were that the protection rate of the vaccine preserved for 15 months was lower than that of the vaccine preserved for 12 months and showed that the two combined vaccine could be preserved for at least 12 months at 2 to 8 ℃.

Key words: gosling plague; goose paramyxorivrus; inactivated two combined vaccine
