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 a Development Officer - Extensive Livestock at the Trangie Agricultural Research Centre and has worked in commercial agricultural industries as well as the Department of Primary Industries.  She has been involved in research and the application of livestock genetic improvement programs in industry. Tracie has worked in various sections within the Department of Primary Industries since 1990, but has mainly been involved in the livestock units; sheep and cattle, other sections she has worked in include soils, feral animals and cropping.

Previous work within the Department has included, Beef genetics research relating to green-house gas emissions and feed efficiency; site manager for the Sheep CRC Information Nucleus Flock at Trangie, genetic analysis and extension of research (sheep industry) for the Advanced Breeding Services unit (NSW DPI) and daily management of sheep research projects (QPLU$ & CTSE).  Tracie completed a Research Masters in animal breeding (Genetic analyses of flystrike in sheep).
