Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Pathology
  • Surgery

Stephen J. LeBlanc spends much of his time researching Dairy cattle, Metritis, Animal science, Ice calving and Endometritis. His work carried out in the field of Dairy cattle brings together such families of science as Incidence, Culling, Biotechnology, Mastitis and Pregnancy rate. His biological study spans a wide range of topics, including Postpartum period and Retained placenta.

His Animal science study incorporates themes from Veterinary medicine, Bovine respiratory disease and Insemination. His Ice calving study combines topics in areas such as NEFA, Endocrinology, Herd and Internal medicine. His Endometritis research incorporates themes from Vaginal discharge and Gynecology.

His most cited work include:

  • Defining postpartum uterine disease in cattle. (817 citations)
  • Defining and diagnosing postpartum clinical endometritis and its impact on reproductive performance in dairy cows. (540 citations)
  • Monitoring Metabolic Health of Dairy Cattle in the Transition Period (347 citations)

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

Stephen J. LeBlanc mostly deals with Animal science, Ice calving, Dairy cattle, Herd and Lactation. His Animal science research is multidisciplinary, relying on both Veterinary medicine, Metritis, Lameness and Insemination. Stephen J. LeBlanc interconnects Mastitis and Endometritis in the investigation of issues within Metritis.

As a part of the same scientific family, he mostly works in the field of Endometritis, focusing on Gynecology and, on occasion, Vagina. The Ice calving study combines topics in areas such as Endocrinology, Dry matter, Internal medicine, Confidence interval and NEFA. Stephen J. LeBlanc focuses mostly in the field of Dairy cattle, narrowing it down to matters related to Incidence and, in some cases, Tulathromycin and Bovine respiratory disease.

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

Stephen J. LeBlanc mainly focuses on Animal science, Ice calving, Herd, Lactation and Mastitis. His Animal science study combines topics from a wide range of disciplines, such as Veterinary medicine, Metritis and Lameness. His research investigates the connection between Metritis and topics such as Retained placenta that intersect with issues in Milk fever.

His studies in Ice calving integrate themes in fields like Dry matter, Weaning, Haptoglobin, Endometritis and Physiology. His Culling study in the realm of Herd connects with subjects such as Psychology. Stephen J. LeBlanc has researched Lactation in several fields, including Respiratory burst and Endocrinology.

Between 2016 and 2021, his most popular works were:

  • Management practices for male calves on Canadian dairy farms. (34 citations)
  • Behavioral changes before metritis diagnosis in dairy cows. (29 citations)
  • Investigating the within-herd prevalence and risk factors for ketosis in dairy cattle in Ontario as diagnosed by the test-day concentration of β-hydroxybutyrate in milk. (28 citations)

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

  • Internal medicine
  • Pathology
  • Surgery

His primary areas of investigation include Animal science, Herd, Ice calving, Lactation and Milking. Stephen J. LeBlanc has included themes like Odds ratio, Metritis, Cohort study, Lameness and Multivariable model in his Animal science study. His Metritis research integrates issues from Retained placenta, Mastitis, Vaginal discharge, Innate immune system and Subclinical infection.

His Herd research incorporates elements of Breed, Dairy cattle and Colostrum. His Ice calving research is multidisciplinary, incorporating elements of Logistic regression, Quartile, Percentage point, Hazard ratio and Bovine respiratory disease. His research integrates issues of Internal medicine and Endocrinology in his study of Lactation.
