which method gives more titer either vaccinating ND and IB vaccine separately or combination?

Vaccinating ND and IB separately generally gives a higher and more consistent antibody titer than the combined vaccine, as each antigen gets a stronger immune response when given alone. However, combination vaccines are often used for practicality and to reduce handling stress.

Mostly as both vaccines replicate in the mucosa of the trachea. But not always; it can differ depending on several factors (vaccine type, strain compatibility, bird health, administration method, and timing).
