Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Biochemistry
  • Botany

His primary scientific interests are in Rumen, Agronomy, Forage, Lotus corniculatus and Animal science. His Rumen study combines topics from a wide range of disciplines, such as Digestion, Plant protein and Botany. Fodder and Grazing are the core of his Agronomy study.

The concepts of his Grazing study are interwoven with issues in Perennial plant, Dry matter and Pasture. His Forage study frequently involves adjacent topics like Legume. His Animal science research integrates issues from Onobrychis viciifolia, Protein digestion and Larva.

His most cited work include:

  • The effect of condensed tannins on the nutrition and health of ruminants fed fresh temperate forages: a review (730 citations)
  • Determination of extractable and bound condensed tannin concentrations in forage plants, protein concentrate meals and cereal grains (654 citations)
  • The implications of condensed tannins on the nutritive value of temperate forages fed to ruminants. (469 citations)

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

T. N. Barry mainly investigates Agronomy, Animal science, Grazing, Rumen and Pasture. His Lolium perenne, Trifolium repens, Lotus corniculatus, Forage and Fodder study are his primary interests in Agronomy. His Lotus corniculatus research includes themes of Protein digestion and Plant protein.

As part of the same scientific family, he usually focuses on Animal science, concentrating on Sambar deer and intersecting with Cervus unicolor. His research in Grazing intersects with topics in Perennial plant, Dry matter, Willow, Red Clover and Domestic sheep reproduction. T. N. Barry has researched Rumen in several fields, including Hay, Digestion, Skatole and Protein degradation.

He most often published in these fields:

  • Agronomy (54.41%)
  • Animal science (44.12%)
  • Grazing (43.38%)

What were the highlights of his more recent work (between 2003-2013)?

  • Agronomy (54.41%)
  • Pasture (38.97%)
  • Grazing (43.38%)

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

T. N. Barry focuses on Agronomy, Pasture, Grazing, Dry matter and Willow. His Agronomy research incorporates themes from Rumen and Animal science. His work deals with themes such as Skatole, Plant protein, Bacterial growth, Microbiology and Forage, which intersect with Rumen.

His Grazing research is multidisciplinary, incorporating elements of Domestic sheep reproduction and Animal nutrition. T. N. Barry has included themes like Agroforestry and Haemonchus contortus in his Willow study. In his research, Fermentation and Neutral Detergent Fiber is intimately related to Tannin, which falls under the overarching field of Lotus corniculatus.

Between 2003 and 2013, his most popular works were:

  • Alternative temperate forages containing secondary compounds for improving sustainable productivity in grazing ruminants (149 citations)
  • The effect of condensed tannins from Lotus corniculatus on the proteolytic activities and growth of rumen bacteria (117 citations)
  • The feeding value of forage brassica plants for grazing ruminant livestock (61 citations)

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

  • Ecology
  • Biochemistry
  • Botany

The scientist’s investigation covers issues in Agronomy, Grazing, Pasture, Dry matter and Trifolium repens. He frequently studies issues relating to Rumen and Agronomy. His Rumen study integrates concerns from other disciplines, such as Prevotella and Eubacterium.

His Grazing study frequently links to other fields, such as Lotus corniculatus. T. N. Barry studied Trifolium repens and Lolium perenne that intersect with Domestic sheep reproduction, Protein digestion, Tannin and Neutral Detergent Fiber. In his work, Protein degradation and Legume is strongly intertwined with Skatole, which is a subfield of Forage.
