Research Interests

Pigs, sheep, and beef; developing breeding programs for ostriches and Sydney rock oysters.

Other interests include:

  • Factors affecting  mortality in piglets, lambs and calves and opportunities for genetic evaluation to improve survival
  • Reproduction and maternal performance attributes of sows, ewes and beef cattle
  • Development and body composition of gilts
  • Feed efficiency and feed intake
  • Developing selection  criteria for behavioural attributes which could improve both welfare and  performance (sows)
  • Immune competence  and stress effects on performance
  • Use of novel  physiological traits in breeding programs, eg juvenile IGF-I in pig breeding  and progesterone for yearling lambing outcomes (ewes)
  • Breeding program  design and operational issues affecting practical implementation
  • Meat quality comparisons
  • Parameter estimation and genetic evaluation systems
  • Inbreeding and mate selection
  • Industry consultancy
