Overview

What is he best known for?

The fields of study he is best known for:

  • Biochemistry
  • Internal medicine
  • Metabolism

Richard A. Erdman mainly focuses on Animal science, Lactation, Internal medicine, Endocrinology and Dairy cattle. His Animal science research is multidisciplinary, relying on both Urea and Rumen. As a member of one scientific family, Richard A. Erdman mostly works in the field of Lactation, focusing on Sunflower oil and, on occasion, Unsaturated fatty acid, Corn oil, Oleic acid and Fatty acid.

His Internal medicine study combines topics in areas such as Conjugated linoleic acid, ACACA, Gene expression and Cattle feeding. His work on Feed conversion ratio as part of general Endocrinology study is frequently linked to Regression analysis, therefore connecting diverse disciplines of science. His Dry matter research includes themes of Silage, Digestion and Latin square.

His most cited work include:

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

His scientific interests lie mostly in Lactation, Food science, Animal science, Silage and Endocrinology. His Lactation study incorporates themes from Dairy cattle, Prolactin, photoperiodism and Fatty acid. His work carried out in the field of Food science brings together such families of science as Dry matter and Milk production.

Richard A. Erdman has included themes like Urea, Agronomy and Milk yield in his Animal science study. His research in Silage intersects with topics in Calcium, Choline and Forage. His work deals with themes such as Conjugated linoleic acid, Internal medicine, Casein and Bovine somatotropin, which intersect with Endocrinology.
