Determining Optimum Time for Administration of Live Intermediate Vaccine of Infectious Bursal Disease to Chickens at Mekelle Farm

The study was conducted from December 2013 to April 2014 to predict the proper age for vaccination of chickens against infectious bursal disease (IBD) and calculate the maternal antibody transfer rate. A total of 99 chickens: 80-day-old chickens and 19 parent chickens’ were randomly selected from Mekelle Farms. Blood samples were collected from heart and wing vein of individual chicken and serum was harvested. Indirect Enzyme Linked Immunosorbent Assay (IELISA) was employed to measure the Maternally Derived Antibodies (MDAs) from chickens of day 2, 18, 21 and antibody titers from parents.
