Overview

What is he best known for?

The fields of study he is best known for:

  • Biochemistry
  • Amino acid
  • Ecology

Animal science, Rumen, Amino acid, Excretion and Agronomy are his primary areas of study. His Animal science research overlaps with Lactation and Total energy. Food science covers David Pacheco research in Rumen.

He interconnects Medicago sativa and Methanogenesis in the investigation of issues within Food science. His Amino acid study integrates concerns from other disciplines, such as Catabolism, Metabolism and Anabolism. The various areas that David Pacheco examines in his Excretion study include Urine, Abomasum, Dietary nitrogen, Digestion and Grazing.

His most cited work include:

  • Methane production from in vitro rumen incubations with Lotus pedunculatus and Medicago sativa, and effects of extractable condensed tannin fractions on methanogenesis (336 citations)
  • Milk protein synthesis as a function of amino acid supply. (120 citations)
  • The route of absorbed nitrogen into milk protein (95 citations)

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

David Pacheco spends much of his time researching Animal science, Rumen, Pasture, Grazing and Agronomy. The Animal science study combines topics in areas such as Amino acid and Excretion. The study incorporates disciplines such as Internal medicine and Food science, Milk protein in addition to Amino acid.

His Rumen study is related to the wider topic of Fermentation. His Grazing study incorporates themes from Fodder and Greenhouse gas. The concepts of his Agronomy study are interwoven with issues in Ruminal fermentation and Animal feed.

He most often published in these fields:

  • Animal science (51.04%)
  • Rumen (36.46%)
  • Pasture (27.08%)

What were the highlights of his more recent work (between 2017-2021)?

  • Animal science (51.04%)
  • Rumen (36.46%)
  • Pasture (27.08%)

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

His scientific interests lie mostly in Animal science, Rumen, Pasture, Forage and Grazing. The concepts of his Animal science study are interwoven with issues in Brassica, Fodder and Excretion. He performs multidisciplinary studies into Rumen and Lactation in his work.

His research integrates issues of Prevotella, Nitrate and Lolium perenne in his study of Pasture. David Pacheco focuses mostly in the field of Forage, narrowing it down to matters related to Fermentation and, in some cases, Methane emissions and Perennial plant. His Grazing research integrates issues from Amino acid, Protein metabolism, Rangeland and Ruminant.

Between 2017 and 2021, his most popular works were:

  • Digestion and nitrogen excretion by Holstein–Friesian cows in late lactation offered ryegrass-based pasture supplemented with fodder beet (12 citations)
  • Rumen digesta and products of fermentation in cows fed varying proportions of fodder beet (Beta vulgaris) with fresh pasture or silage or straw (9 citations)
  • Milk production responses and rumen fermentation of dairy cows supplemented with summer brassicas. (5 citations)

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

  • Biochemistry
  • Ecology
  • Agriculture

His main research concerns Animal science, Rumen, Lactation, Dry matter and Silage. His studies in Animal science integrate themes in fields like Fodder and Pasture. His studies deal with areas such as Dairy cattle, Digestion, Excretion and Acidosis as well as Fodder.

Cohort, Somatic cell, RNA, Mammary gland and Andrology are fields of study that overlap with his Lactation research. His research in Dry matter intersects with topics in Forage and Straw. His work carried out in the field of Silage brings together such families of science as Nutrient, Grazing and Latin square.
