Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Biochemistry
  • Animal science

Roger Hegarty spends much of his time researching Animal science, Agronomy, Rumen, Residual feed intake and Feed conversion ratio. His Animal science research is multidisciplinary, relying on both Ruminant, Biotechnology, Animal nutrition, Livestock and Retention time. His work deals with themes such as Grazing and Greenhouse gas, which intersect with Livestock.

His Rumen study integrates concerns from other disciplines, such as Digestion, Methanogenesis and Fatty acid. His research integrates issues of Agriculture and Beef cattle in his study of Residual feed intake. The Fermentation study combines topics in areas such as Nitrate, Propionate and Methane.

His most cited work include:

  • Cattle selected for lower residual feed intake have reduced daily methane production. (323 citations)
  • Reducing rumen methane emissions through elimination of rumen protozoa (168 citations)
  • Relationship between animal age, intramuscular fat, cooking loss, pH, shear force and eating quality of aged meat from sheep (154 citations)

What are the main themes of his work throughout his whole career to date?

Roger Hegarty focuses on Animal science, Rumen, Agronomy, Methane and Methane production. He has included themes like Feed conversion ratio, Biotechnology and Nitrate in his Animal science study. His Rumen research is multidisciplinary, incorporating elements of Methanogenesis, Propionate and Fatty acid.

His work in Methane tackles topics such as Greenhouse gas which are related to areas like Agriculture, Livestock, Sustainability and Environmental engineering. His Methane production research integrates issues from Repeatability, Feedlot, Respiration and Beef cattle. Roger Hegarty has researched Sire in several fields, including Longissimus Thoracis, Loin, Animal breeding and Monogastric.

He most often published in these fields:

  • Animal science (66.89%)
  • Rumen (27.03%)
  • Agronomy (18.92%)

What were the highlights of his more recent work (between 2015-2021)?

  • Animal science (66.89%)
  • Rumen (27.03%)
  • Nitrate (13.51%)

In recent papers he was focusing on the following fields of study:

His primary areas of investigation include Animal science, Rumen, Nitrate, Beef cattle and Methane production. The concepts of his Animal science study are interwoven with issues in Ruminant, Feed conversion ratio and Grazing. The various areas that he examines in his Rumen study include Nitrous oxide, Propionate and Fatty acid.

Roger Hegarty interconnects Urea, Food science, Calcium nitrate and Ammonia in the investigation of issues within Nitrate. His biological study spans a wide range of topics, including Greenhouse gas, Methane, Predictive value, Licking and Forage. His studies deal with areas such as Heritability, Repeatability, Carbon dioxide production and Respiration as well as Methane production.

Between 2015 and 2021, his most popular works were:

  • A universal equation to predict methane production of forage-fed cattle in Australia (88 citations)
  • Review: Biological determinants of between-animal variation in feed efficiency of growing beef cattle. (51 citations)
  • Use of short-term breath measures to estimate daily methane production by cattle. (30 citations)

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

  • Agriculture
  • Biochemistry
  • Ecology

His scientific interests lie mostly in Animal science, Dry matter, Methane production, Rumen and Beef cattle. As part of his studies on Animal science, he often connects relevant areas like Ruminant. His Dry matter study combines topics in areas such as Digestion and Feces.

The study incorporates disciplines such as Repeatability and Respiration in addition to Methane production. Roger Hegarty usually deals with Rumen and limits it to topics linked to Nitrate and Ammonia and Nitrous oxide. He combines subjects such as Methanogenesis, Feed conversion ratio, Residual feed intake, Forage and Environmental impact of agriculture with his study of Beef cattle.
