Cholera Adds to PRRS Woes

Hog cholera virus has hit the Thuy Phuong Pig Research Center Animals at the research center attached to the National Institute of Animal Husbandry in Hanoi.

The herd has already culled around 200 animals and tests on 52 samples of the culled pigs have confirmed positive pathology for hog cholera. Three others tested positive for Porcine Reproductive and Respiratory Syndrome (PRRS) virus, which is currently ravaging through Viet Nam's pig populations in central and northern provinces.

Deputy head of the Animal Health Department, Hoang Van Nam, said the three pigs with PRRS had not developed symptoms.

The Animal Health Department released statistics this week that showed more than 21,800 pigs were detected with the PRRS virus in 10 provinces from April 21 to 28.

The department had previously reported that more than 222,000 pigs in these provinces had been infected since March.
