Abstract [en]

The study was conducted to know the rate of maternally derived antibodies (MDAs) transfer from parents to their offspring and declining the MDAs in their chicks at 0, 7, 14, and 21 days of age against four major poultry viruses like Newcastle disease virus (NDV), Infectious bronchitis virus (IBV), Infectious bursal diseases virus (IBDV), and Avian Reo virus (ARV). The MDAs was studied on Grandparent (GP) to Parent stock (PS), and Parent stock (PS) to broiler at 30 weeks and 50 weeks of age in Cobb-500 broiler strain chicken. The MDAs was measured from serum antibody titer by indirect ELISA test. The MDAs transfer rate against NDV from GP to PS at 50 weeks of age was higher (68.82%) than at 30 weeks of age but in case of PS to broiler it was higher (66.01%) at 30 weeks of age and its persistent rate also higher (7.96%) up to 21th days of age. Against IBV, MDAs transfer rates were higher in PS to broiler than GP to PS of both ages and highest rates were revealed in PS to broiler at 30 weeks of age as 70.72%. On the other hand, among all lines MDAs transfer rates against IBDV was higher (86.94%) in GP to PS at 30 weeks of age. For ARV, the MDAs transfer rates were highest in GP to PS in both ages than PS to broiler and within GP to PS at 50 weeks of age, it was highest (94.87%) than 30 weeks of age. Accordingly, the poultry producer may help to develop an effective vaccination schedule by considering the MDAs from above experiment.
