Abstract

Failure of transfer of passive immunity (FTPI) in dairy calves has substantial health consequences, impacting wellbeing and performance. There have been no recent estimates of the prevalence of FTPI on Ontario dairy farms. The objectives of this cross-sectional study were to determine the level of FTPI in both male and female dairy calves across the province of Ontario, as well as determine colostrum management practices through an in-person questionnaire.
