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.
