“[I]t is not just the unknowns that [veterinary researchers] should be concerned about but [also] the re-emergence of what we consider to be the ‘knowns’...” (Priestnall and Smith 2012:272). The interplay between knowledge and ignorance is the starting point to explore ignorance communication in veterinary research using a dynamic model of knowledge and ignorance mobilization in science. Harnessing empirical evidence from The Veterinary Journal contributions, the aim is to probe dynamics at critical junctures in the model. Finally, Priestnall and Smith’s (2012) overt consideration for veterinary ignorance joins a convergent interest for ignorance from the natural and the social sciences.
