Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Internal medicine
  • Biochemistry

His primary areas of study are Dairy cattle, Animal science, Lactation, Ice calving and Grazing. His Dairy cattle research is multidisciplinary, incorporating perspectives in Pregnancy, Infertility, Veterinary medicine, Animal nutrition and Body condition score. His work deals with themes such as Vaginal discharge and Pasture, which intersect with Animal science.

His Lactation study incorporates themes from Internal medicine, Nadir, Dry matter and Endocrinology. His Ice calving research incorporates themes from Parity, Reproduction, Herd, Endometritis and Breed. He combines subjects such as Environmental management system, Stocking and Biotechnology with his study of Grazing.

His most cited work include:

  • Invited review: Body condition score and its association with dairy cow productivity, health, and welfare (678 citations)
  • Invited review : New Perspectives on the Roles of Nutrition and Metabolic Priorities in the Subfertility of High-Producing Dairy Cows (243 citations)
  • Relationships among international body condition scoring systems. (234 citations)

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

His main research concerns Animal science, Dairy cattle, Lactation, Animal nutrition and Ice calving. His studies in Animal science integrate themes in fields like Grazing, Pasture and Reproduction. The concepts of his Pasture study are interwoven with issues in Silage and Hectare.

His Dairy cattle research integrates issues from Total mixed ration, Body condition score, Biotechnology and Veterinary medicine. His Lactation research incorporates elements of Milking, Internal medicine, Genetic strain and Endocrinology. His research integrates issues of Breed, Gene expression, Immune system and Pregnancy rate in his study of Ice calving.

He most often published in these fields:

  • Animal science (56.77%)
  • Dairy cattle (46.62%)
  • Lactation (33.83%)

What were the highlights of his more recent work (between 2015-2021)?

  • Animal science (56.77%)
  • Lactation (33.83%)
  • Ice calving (27.44%)

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

His scientific interests lie mostly in Animal science, Lactation, Ice calving, Grazing and Pasture. His studies link Metabolism with Animal science. His work carried out in the field of Lactation brings together such families of science as Internal medicine, Downregulation and upregulation, Gene expression and Endocrinology.

His Ice calving study combines topics in areas such as Metabolic disorder, Milk protein, Reproduction, Herd and Pregnancy rate. He works mostly in the field of Grazing, limiting it down to concerns involving Milking and, occasionally, Weight gain, Insulin and Dairy herds. John R. Roche usually deals with Pasture and limits it to topics linked to Hectare and Stocking, Agronomy, Lactose and Agricultural science.

Between 2015 and 2021, his most popular works were:

  • Milk Production and Fertility in Cattle. (48 citations)
  • Body condition score and plane of nutrition prepartum affect adipose tissue transcriptome regulators of metabolism and inflammation in grazing dairy cows during the transition period. (32 citations)
  • A 100-Year Review: A century of change in temperate grazing dairy systems. (31 citations)

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

  • Gene
  • Internal medicine
  • Biochemistry

Animal science, Lactation, Internal medicine, Endocrinology and Ice calving are his primary areas of study. His biological study spans a wide range of topics, including Hectare and Grazing, Pasture, Agronomy. His Grazing research focuses on Stocking and how it connects with Milking and Agricultural science.

Lactation is a primary field of his research addressed under Pregnancy. In his study, Gene expression, Proinflammatory cytokine, Metabolic syndrome and Fibrinogen is strongly linked to Immune system, which falls under the umbrella field of Internal medicine. His research integrates issues of Total mixed ration and Herd in his study of Ice calving.
