  • 2013 - Journal of Dairy Science Highly Cited Awards, American Dairy Science Association

Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Disease
  • Pathology

Animal science, Herd, Lactation, Dairy cattle and NEFA are his primary areas of study. His Animal science research includes themes of Veterinary medicine and Relative risk. His Herd research is multidisciplinary, relying on both Milking, Incidence, Subclinical ketosis and Milk yield.

Daryl V. Nydam has included themes like Cryptosporidium hominis and Cryptosporidium in his Dairy cattle study. His NEFA study focuses on Internal medicine and Endocrinology. His work on High plasma as part of general Endocrinology research is often related to Pituitary pars intermedia dysfunction and Pergolide, thus linking different fields of science.

His most cited work include:

  • Evaluation of nonesterified fatty acids and β-hydroxybutyrate in transition dairy cattle in the northeastern United States: critical thresholds for prediction of clinical diseases. (368 citations)
  • Epidemiology of subclinical ketosis in early lactation dairy cattle (285 citations)
  • Enhanced early chondrogenesis in articular defects following arthroscopic mesenchymal stem cell implantation in an equine model. (255 citations)

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

His main research concerns Animal science, Dairy cattle, Herd, Lactation and Internal medicine. His Milking study in the realm of Animal science interacts with subjects such as Ketosis. In his study, Genotype is inextricably linked to Cryptosporidium, which falls within the broad field of Dairy cattle.

His research in Herd intersects with topics in Mastitis, Incidence and Subclinical ketosis. In his work, Automatic milking and Prospective cohort study is strongly intertwined with Subclinical infection, which is a subfield of Lactation. His Internal medicine research focuses on Endocrinology and how it relates to Postpartum period.

He most often published in these fields:

  • Animal science (40.00%)
  • Dairy cattle (25.00%)
  • Herd (24.44%)

What were the highlights of his more recent work (between 2016-2021)?

  • Mastitis (15.56%)
  • Animal science (40.00%)
  • Udder (10.00%)

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

Daryl V. Nydam mostly deals with Mastitis, Animal science, Udder, Somatic cell count and Herd. The study incorporates disciplines such as Lactation and Confidence interval in addition to Animal science. His Lactation study incorporates themes from Endocrinology, Internal medicine, Randomized controlled trial and Aseptic processing.

His Udder research includes elements of Milking and Milk yield. His study in Herd is interdisciplinary in nature, drawing from both Dairy cattle, Incidence and Environmental health. His biological study spans a wide range of topics, including NEFA, Epidemiology and Area under the curve.

Between 2016 and 2021, his most popular works were:

  • A 100-Year Review: Metabolic health indicators and management of dairy cattle. (48 citations)
  • Association between subclinical hypocalcemia in the first 3 days of lactation and reproductive performance of dairy cows. (46 citations)
  • Clinical outcome comparison of immediate blanket treatment versus a delayed pathogen-based treatment protocol for clinical mastitis in a New York dairy herd (28 citations)

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

  • Internal medicine
  • Surgery
  • Pathology

Daryl V. Nydam spends much of his time researching Herd, Udder, Animal science, Lactation and Internal medicine. Daryl V. Nydam undertakes multidisciplinary investigations into Herd and Ketosis in his work. His work is dedicated to discovering how Udder, Milking are connected with Teat canal, Milk yield, Multivariable linear regression and Variance components and other disciplines.

Daryl V. Nydam frequently studies issues relating to Physiology and Lactation. His Internal medicine research incorporates themes from Surgery, Umbilicus and Ice calving. His research investigates the connection between Ice calving and topics such as Endocrinology that intersect with problems in Automatic milking and Allograft inflammatory factor 1.
