BURSAL PROTECTION

Good protection is necessary against IBDV and is followed by vaccination to shield the bursa of Fabricius.

The bursa of Fabricius is, a specialized organ that is necessary for “B” cell development in birds. The bursa is an epithelial and lymphoid organ that is found only in birds. The “B” in “B cell” refers to bursa derived.

To establish Bursal protection, Merial offers a wide variety of IBDV vaccines including live Classic (mild, intermediate, potentiated intermediate and intermediate plus strains), variant (Delaware) and inactivated vaccines.
