Research Interests

  • Effect of housing characteristics (floor type, underfoot conditions, space allowance etc) on animal welfare and performance of finishing beef cattle
  • Predisposing factors for disease and immune-competence in artificially-reared dairy and suckled beef calves from birth to weaning.
  • Transcriptomic and immunological characterisation of colostrum from dairy and beef cows with implications for calf health and welfare
  • Characterisation of the welfare and performance responses of calves to disbudding and castration procedures
  • Bovine respiratory disease (BRD) pathogen diagnostics using next generation sequencing
  • Identification of DNA based biomarkers for susceptibility to BRD
  • Characterisation of contract rearing and associated biosecurity and disease risks, and outcomes
