  • Ecology
  • Bacteria
  • Biochemistry

Richard J. Dewhurst mainly focuses on Rumen, Dairy cattle, Food science, Animal science and Silage. His Rumen research is multidisciplinary, incorporating elements of Sire, Metabolism and Metagenomics. His Dairy cattle research incorporates themes from Environmental health, Mastitis, Disease, Risk of infection and Confounding.

His Food science study also includes fields such as

  • Polyunsaturated fatty acid which intersects with area such as Conjugated linoleic acid,
  • Fatty acid, which have a strong connection to Forage. His Animal science study incorporates themes from Udder and Digestion. His Silage research includes themes of Dry matter and Red Clover.

His most cited work include:

  • Increasing the concentrations of beneficial polyunsaturated fatty acids in milk produced by dairy cows in high-forage systems (396 citations)
  • On the relationship between lactational performance and health: is it yield or metabolic imbalance that cause production diseases in dairy cattle? A position paper (356 citations)

The concepts of his Food science study are interwoven with issues in Methane production and Fatty acid. His biological study spans a wide range of topics, including Compositional data, Biotechnology and Computational biology.

Between 2017 and 2021, his most popular works were:

  • Assembly of 913 microbial genomes from metagenomic sequencing of the cow rumen. (206 citations)
  • Addressing global ruminant agricultural challenges through understanding the rumen microbiome: past, present and future (91 citations)
  • Identification, Comparison, and Validation of Robust Rumen Microbial Biomarkers for Methane Emissions Using Diverse Bos Taurus Breeds and Basal Diets (26 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Bacteria
  • Biochemistry

Richard J. Dewhurst focuses on Rumen, Metagenomics, Beef cattle, Animal science and Microbiome. Rumen and Residual feed intake are two areas of study in which he engages in interdisciplinary research. His studies deal with areas such as Biotechnology, Food science, Methanogenesis and Anaerobic bacteria as well as Metagenomics.

His research investigates the connection with Food science and areas like Methane which intersect with concerns in Gene and Breed. His Animal science research includes elements of Perennial plant, Relative species abundance and Forage. He combines subjects such as Genome, Computational biology and Microbial ecology with his study of Microbiome.
