Genetic variation in response of turkeys to experimental infection with Bordetella avium.

ABSTRACT

One hundred ninety-six male and female turkeys representing two genetic lines were experimentally infected with Bordetella avium. The lines of turkeys included a randombred control line (RBC2) and a subline (F) of RBC2 selected for increased 16-wk body weight. No difference was found between lines RBC2 and F in the number of days to onset of clinical signs, and no mortality due to B. avium infection was observed in either line. Interestingly, however, a significant depression (12%) occurred in body weight of F line poults infected with B. avium, but no significant depression occurred in body weight of RBC2 poults.
