Overview

David Johnston is affiliated with the University of New England in Australia, with a research focus spanning Agricultural and Biological Sciences as well as Biochemistry, Genetics, and Molecular Biology. Their work covers multiple subfields including Genetics, Agronomy and Crop Science, Animal Science and Zoology, Ecology, Evolution, Behavior and Systematics, and Forestry.

The main topics addressed in Johnston's research include genetic and phenotypic traits in livestock, ruminant nutrition and digestive physiology, agronomic practices and intercropping systems, animal genetics and reproduction, vector-borne animal diseases, agroforestry and silvopastoral systems, and reproductive physiology in livestock.

Johnston has published several papers in various academic venues, with recent notable contributions such as:

  • Comparison of Gene Editing Versus Conventional Breeding to Introgress the POLLED Allele Into the Tropically Adapted Australian Beef Cattle Population (2021) in Frontiers in Genetics
  • Performance and nutrient utilisation of dairy cows offered silages produced from three successive harvests of either a red clover-perennial ryegrass sward or a perennial ryegrass sward (2020) in Irish Journal of Agricultural and Food Research
  • An investigation into potential genetic predictors of birth weight in tropically adapted beef cattle in northern Australia (2023) in Animal Production Science
  • The effect of post-harvest treatment of field beans on dairy cow performance and nutrient utilisation (2021) in Livestock Science
  • A method for deriving the genetic matrix needed for selection across combinations of breeds (2020) in Journal of Animal Breeding and Genetics

Johnston frequently collaborates with co-authors such as Katerina Theodoridou, C.P. Ferris, Kirsty Moore, Maci L. Mueller, and John B. Cole. Their publication record includes multiple papers in Animal Production Science, Frontiers in Genetics, Irish Journal of Agricultural and Food Research, Livestock Science, and Journal of Animal Breeding and Genetics.
