Ceva Animal Health Indonesia (Ceva Indonesia) recently conducted a seminar about Newcastle disease (ND) in Bogor. This seminar is part of C.H.I.C.K Day program which has been routinely conducted by Ceva since 2010. The seminar was attended by around 100 participants from the broiler and layer sector.
Prof. Wayan Wibawan of Bogor Agricultural University said that the ND virus was first discovered in Bogor in Indonesia in 1926.
According to Christophe Cazaban – poultry biological scientific direction officer of Ceva Sante Animale France, before 1960, ND virus strains found were only genotype I, II and III. But now in some countries genotype IX has been found. He continued, in Indonesia, the evolution of ND virus has been on the genotype VII.
The evolution of ND virus logically requires a suitable vaccine. However based on field trials, said Cazaban, classical vaccine currently available are still protective against the ND virus that has changed. The result of challenge test conducted by Ceva showed that classical vaccines (Lasota/genotype II strain) were protective against current ND virus and no significant differences with genotype VII strain vaccine.
To control current ND virus, Cazaban recommends to improve biosecurity management in farms, use good vaccine, apply proper vaccination techniques and make good vaccination program.
Ceva poultry regional market manager, Nitiwat Kaewpowat added that C.H.I.C.K (Ceva Hatchery Immunization Control Keys) program is a solution to control ND virus better. This program can optimise the success of vaccination by observing vaccine quality, dosage accuracy, quality of injection and vaccination rate. This program includes five areas of focus such as vaccines, equipment, vaccination technique, monitoring & diagnosis and expertise & training.
