What is he best known for?
The fields of study he is best known for:
- Genetics
- Animal science
- Statistics
His main research concerns Animal science, Beef cattle, Heritability, Biotechnology and Herd.
His Animal science course of study focuses on Feed conversion ratio and Weight gain.
The study incorporates disciplines such as Ice calving, Weaning, Brahman, Agricultural science and Reproduction in addition to Beef cattle.
His Heritability research is multidisciplinary, incorporating elements of Rump and Residual feed intake.
As part of one scientific family, David Johnston deals mainly with the area of Rump, narrowing it down to issues related to the Intramuscular fat, and often Hereford cattle.
His research integrates issues of Animal model and Animal breeding in his study of Biotechnology.
His most cited work include:
- Genetic and phenotypic variance and covariance components for feed intake, feed efficiency, and other postweaning traits in Angus cattle (432 citations)
- Genetic analyses of live-animal ultrasound and abattoir carcass traits in Australian Angus and Hereford cattle. (117 citations)
- Genome-wide association studies of female reproduction in tropically adapted beef cattle. (107 citations)
What are the main themes of his work throughout his whole career to date?
David Johnston focuses on Animal science, Beef cattle, Heritability, Brahman and Genetic correlation.
His Animal science study incorporates themes from Feed conversion ratio and Ice calving.
His work carried out in the field of Beef cattle brings together such families of science as Rump, Herd, Biotechnology and Sire.
His Heritability research includes themes of Hereford cattle and Tenderness.
His Brahman study combines topics from a wide range of disciplines, such as Coat and Reproduction.
He interconnects Residual feed intake and Marbled meat in the investigation of issues within Feedlot.
He most often published in these fields:
- Animal science (61.82%)
- Beef cattle (57.27%)
- Heritability (30.00%)
What were the highlights of his more recent work (between 2014-2021)?
- Beef cattle (57.27%)
- Animal science (61.82%)
- Reproduction (20.00%)
In recent papers he was focusing on the following fields of study:
His primary areas of study are Beef cattle, Animal science, Reproduction, Brahman and Biotechnology.
His work focuses on many connections between Beef cattle and other disciplines, such as Breed, that overlap with his field of interest in Statistics.
Animal science is often connected to Ice calving in his work.
His Ice calving study integrates concerns from other disciplines, such as Feedlot, Weaning, Residual feed intake and Marbled meat.
David Johnston has included themes like Zoology and Northern australia in his Reproduction study.
His Biotechnology research includes elements of Herd and Heritability.
Between 2014 and 2021, his most popular works were:
- Soil temperature and soil water potential under thin oxodegradable plastic film impact on cotton crop establishment and yield (10 citations)
- E7 (1057ΔTA) mutation of the acidic α-glucosidase gene causes Pompe's disease in Droughtmaster cattle. (5 citations)
- Genetic parameters for calving difficulty using complex genetic models in five beef breeds in Australia (5 citations)
In his most recent research, the most cited papers focused on:
- Genetics
- Statistics
- Ecology
David Johnston mainly focuses on Beef cattle, Animal science, Herd, Sire and Ice calving.
David Johnston integrates Animal science and Genetic correlation in his research.
Many of his studies on Genetic correlation apply to Genetic distance as well.
His Herd research is multidisciplinary, relying on both Breed, Genetics and Shorthorn.
The various areas that David Johnston examines in his Sire study include Biotechnology and Heritability.
His Ice calving research is multidisciplinary, incorporating perspectives in Feedlot, Weaning, Residual feed intake and Marbled meat.
