Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Biochemistry
  • Animal science

His primary areas of investigation include Lactation, Dairy cattle, Animal science, Ice calving and Food science. The concepts of his Lactation study are interwoven with issues in Monensin, Dry matter and Confidence interval. His Dairy cattle research incorporates themes from Rumen, Artificial insemination, Credible interval and Acidosis.

His studies in Animal science integrate themes in fields like Internal medicine, Insemination and Endocrinology. Ian J. Lean interconnects Estrous cycle and Pregnancy rate in the investigation of issues within Ice calving. Ian J. Lean combines subjects such as Milk production and Fatty acid with his study of Food science.

His most cited work include:

  • A Body Condition Scoring Chart for Holstein Dairy Cows (1968 citations)
  • Milk fever in dairy cows: A review of pathophysiology and control principles (182 citations)
  • Hypocalcemia in dairy cows: meta-analysis and dietary cation anion difference theory revisited. (174 citations)

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

Ian J. Lean spends much of his time researching Animal science, Dairy cattle, Lactation, Ice calving and Dry matter. His Animal science research includes themes of Rumen, Endocrinology and Internal medicine. His study in Dairy cattle is interdisciplinary in nature, drawing from both Urea, Amino acid, Monensin, Meta-analysis and Milk production.

The Lactation study which covers Vitamin D and neurology that intersects with Vitamin. His work carried out in the field of Ice calving brings together such families of science as Mastitis, Fertility, Urine and Estrous cycle. His Dry matter study also includes

  • Neutral Detergent Fiber most often made with reference to Food science,
  • Silage which connect with Hay.

He most often published in these fields:

  • Animal science (57.85%)
  • Dairy cattle (33.06%)
  • Lactation (29.75%)

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

  • Animal science (57.85%)
  • Lactation (29.75%)
  • Dairy cattle (33.06%)

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

His primary scientific interests are in Animal science, Lactation, Dairy cattle, Beef cattle and Reproduction. His research in the fields of Dry matter overlaps with other disciplines such as Microbiome. His Lactation research is multidisciplinary, incorporating perspectives in Cholecalciferol, Vitamin D and neurology and Insulin.

His Dairy cattle study combines topics in areas such as Herd, Reproductive management and Environmental health. His study on Beef cattle also encompasses disciplines like

  • Pasture which intersects with area such as Glycogen, Animal feed, Silage and Hay,
  • Rest period and related Biceps and NEFA. His work in the fields of Ice calving, such as Metritis, overlaps with other areas such as Retained placenta.

Between 2017 and 2021, his most popular works were:

  • Meta-analysis of the effects of prepartum dietary cation-anion difference on performance and health of dairy cows. (34 citations)
  • Effects of prepartum dietary cation-anion difference intake on production and health of dairy cows: A meta-analysis. (27 citations)
  • Meta-analysis to predict the effects of metabolizable amino acids on dairy cattle performance (16 citations)

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

  • Internal medicine
  • Biochemistry
  • Pathology

His primary areas of study are Animal science, Ice calving, Lactation, Urine and Retained placenta. His Animal science research is mostly focused on the topic Beef cattle. His Urine research is multidisciplinary, relying on both Mastitis, Metritis and Milk yield.

His Meta-analysis study integrates concerns from other disciplines, such as Amino acid, Dairy cattle and Milk protein. The various areas that Ian J. Lean examines in his Artificial insemination study include Rate ratio and Fertility. His Milk fever study combines topics from a wide range of disciplines, such as Breed and Dry matter.
