Abstract:
Newcastle Disease is the most devastating viral disease that spreads worldwide with a high
impact on the economy. This disease is endemic in many parts of Ethiopia. Vaccination
against Newcastle disease is one of the main prevention and control measures in countries
with an endemic occurrence of Newcastle disease virus. A cross‐sectional study design with
purposive sampling methods was conducted to detect the seroconversion status of
the Newcastle disease vaccine. Before data collection, chickens with a previous history of
vaccination against the NDV were included in the sampling of birds. Blood samples were
collected from nineteen (19) farms. The blood sample collections were considered different
parameters; sex, age, breed, production stage, hygiene and vaccination history during the data
collection time. A total of 394 blood samples of 3ml were collected from the brachial vein
using 3ml disposable syringes.
