Evaluation Of VAXXITEK® HVT + IBD Vaccine At A Canadian Broiler Company

Coulombe L. & Delvecchio A.

Field evaluation of vaccines often proves challenging due to the increased amount of variation introduced by modern production practices. The present study attempted to evaluate VAXXITEK HVT +IBD in a broiler complex in Canada where clear evidence of IBD field challenge was occurring. Historical production data was compared to the trial period to examine any treatment differences. The farms receiving VAXXITEK HVT +IBD were compared to control farms receiving the company’s standard vaccination program for 4 time periods from June 2010 to February 2011. Birds receiving VAXXITEK HVT +IBD showed significant production improvements during the study as compared to controls.
