Porcine Reproductive and Respiratory Syndrome Virus, also called blue ear, has not occurred in Hanoi for ten days, said the capital city Department of Animal Health on June 23.
Veterinaries continued treating diseased pigs in suburban Hanoi districts Gia Lam, Dong Anh, Thuong Tin and Me Linh.
Despite its recession, animal health officials warned that farm owners should keep alert for the disease as there will be several heat waves moving through the northern and central regions of Vietnam over the next three to four days to badly affect animal’s resistance to illness.
Therefore, breeders need to keep their farms clean and their animals fully fed and vaccinated.
Specifically, breeders should only purchase breeding pigs from known companies with testing certificates from relevant agencies.
Furthermore, farmers should quarantine new pigs in separate pigsties for 21 days.
