Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Disease
  • Virus

John R. Campbell mostly deals with Veterinary medicine, Feces, Animal science, Herd and Cryptococcus gattii. His Veterinary medicine research incorporates elements of Odds ratio, Case-control study and Matched control. John R. Campbell focuses mostly in the field of Feces, narrowing it down to matters related to Pasture and, in some cases, Ostertagia ostertagi, Bulk tank and Animal husbandry.

His Animal science research is multidisciplinary, relying on both Tetracycline, Drug resistance and Anthelmintic. The study incorporates disciplines such as Predictive value of tests, Gynecology, False Negative Reactions and Confidence interval in addition to Herd. His Cryptococcus gattii research incorporates elements of Mammal, Opportunistic Sampling and Wildlife.

His most cited work include:

  • Cryptococcus gattii in wildlife of Vancouver Island, British Columbia, Canada. (59 citations)
  • Evaluation of client compliance with short-term administration of antimicrobials to dogs. (54 citations)
  • A longitudinal study of gastrointestinal parasites in Canadian dairy farms. The value of an indirect Ostertagia ostertagi ELISA as a monitoring tool. (52 citations)

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

Veterinary medicine, Animal science, Herd, Beef cattle and Ice calving are his primary areas of study. His research in Veterinary medicine intersects with topics in Feedlot, Antimicrobial, Ostertagia ostertagi, Disease and Antibiotic resistance. His Feedlot research includes themes of Livestock and Internal medicine.

John R. Campbell has researched Animal science in several fields, including Feces, Pasture, Cattle Diseases, Grazing and Anthelmintic. In general Herd study, his work on Cow-calf often relates to the realm of Tritrichomonas foetus, thereby connecting several areas of interest. His work deals with themes such as Body weight and Claw, which intersect with Beef cattle.

He most often published in these fields:

  • Veterinary medicine (33.64%)
  • Animal science (30.00%)
  • Herd (26.36%)

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

  • Herd (26.36%)
  • Animal science (30.00%)
  • Ice calving (12.73%)

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

His primary areas of study are Herd, Animal science, Ice calving, Beef cattle and Weaning. His Herd study is concerned with Veterinary medicine in general. His Veterinary medicine research is multidisciplinary, incorporating perspectives in Livestock, Feedlot cattle, Antibiotic resistance and Diarrhea.

His study on Sire is often connected to Repeatability as part of broader study in Animal science. His study focuses on the intersection of Beef cattle and fields such as Anthelmintic with connections in the field of Species diversity, Feedlot, Epidemiology, Feces and Nematodirus. His research on Disease also deals with topics like

  • Foot rot, which have a strong connection to Virus,
  • Viral diarrhea that intertwine with fields like Vaccination and Antibody.

Between 2017 and 2021, his most popular works were:

  • Effect of ruminal acidosis and short-term low feed intake on indicators of gastrointestinal barrier function in Holstein steers (15 citations)
  • Quantifying subclinical trauma associated with calving difficulty, vigour, and passive immunity in newborn beef calves. (6 citations)
  • Antimicrobial resistance in fecal Escherichia coli and Campylobacter spp. from beef cows in western Canada and associations with herd attributes and antimicrobial use. (5 citations)

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

  • Internal medicine
  • Disease
  • Pathology

His scientific interests lie mostly in Ice calving, Herd, Passive immunity, Physiology and Veterinary medicine. His work carried out in the field of Herd brings together such families of science as Florfenicol and Livestock. John R. Campbell usually deals with Passive immunity and limits it to topics linked to Placebo and Randomized controlled trial.

His study in Physiology is interdisciplinary in nature, drawing from both Blood sampling and Subclinical infection. In his articles, he combines various disciplines, including Veterinary medicine and Reason for Treatment. His research integrates issues of Incidence, Bovine respiratory disease and Cow-calf in his study of Beef cattle.
