Tracie Bird-Gardiner

Research interests

  • Animal breeding and genetics
  • Genetic improvement of feed efficiency and greenhouse gas emissions in beef cattle
  • Genetic improvement for disease resistance and welfare
  • Improving reproductive performance in livestock


Tracie is currently involved with the Beef Genetics unit of the NSW Department of Primary Industries, but has also worked in other sections (mainly livestock) within the Department since 1990.

Previous work within the Department included, site manager for the Sheep CRC Information Nucleus Flock at Trangie, genetic analysis and extension of research for the Advanced Breeding Services unit and daily management of sheep research projects.

Tracie recently completed a Research Masters in animal breeding (Genetic analyses of flystrike in sheep) and also works in the Cropping Systems unit.

Current projects

  • Improvement of feed utilisation and reduced methane emissions for cattle
  • Divergent selection for feed efficiency and for methane in cattle
  • Establishment of a Genomics research cow herd (Angus Sire Benchmarking Program)
