Secretary of the Champhai District Vawkvulh (Pig rearers) Association Lalrinzuala today said that at least 25 pigs have died in the central area of Champhai town since last week while many others were taken sick.
The association proposed to hold a meeting on Sunday to assess the situation and seek assistance of the government, he said.
State Animal Husbandry and Veterinary secretary B. Lalthanliana said that the samples of pigs and piglets taken ill due to unknown disease in Champhai town were collected and expected to arrive at Aizawl on Monday for laboratory tests.
"All those pigs which died were immediately buried and the veterinarians could not collect samples from the carcass due to incessant rain," he said, adding that samples of sick pigs were collected.
Almost 4,000 pigs and piglets died in the six districts of Mizoram last year due to PRRS with the Champhai being the hardest hit at the toll of over 3,000.
