The finding was based on a report filed by a team sent last week to the affected areas bordering Manipur, the officials said.
The samples of dead chickens taken from Sakawrdai, Khawpuar, Vaitin and surrounding villages were examined and it was found that they were afflicted with 'Ranikhet' disease, they said.
The team also collected samples of sick swines which would be tested in laboratories to determine whether they were suffering from the dreaded Porcine Reproductive and Respiratory Syndrome (PRRS).
Vaccination camps were organised in three villages.
The villagers were asked not to import animals from neighbouring Myanmar where PRRS was prevalent, the officials added.
