Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Internal medicine
  • Statistics

Bert J. Tolkamp spends much of his time researching Statistics, Food science, Animal science, Meal and Food intake. His study in the field of Frequency distribution also crosses realms of Interval and General validity. He has researched Food science in several fields, including Organic matter, Nutrient and Animal nutrition, Monogastric.

His study looks at the intersection of Animal science and topics like Basal metabolic rate with Nutrient intake.
