The general premise of vaccination, that it presents an animal with an imprint of disease so the immune system can respond more quickly and effectively to the real thing, isn’t complex. However, with the rapid advances in vaccine technology, and broad choice of new and proven product offerings, selecting a vaccine, as well as injection timing appropriate for your operation, certainly can be.
Say you spot an animal, probably a recent arrival, looking rough. It appears gaunt and sluggish, is breathing heavily, dragging its feet and maybe even suffering from nasal discharge, diarrhea and or fever. What conditions and treatments are on your radar? Bovine respiratory disease (BRD) is a good guess, but don’t end your list there. Other dangerous conditions also can mimic respiratory symptoms.
