Overview

J.H. Clark is affiliated with the University of Illinois at Urbana-Champaign in the United States. Their research primarily focuses on agricultural and biological sciences, with significant contributions to subfields including agronomy and crop science, animal science and zoology, nutrition and dietetics, and genetics.

The scientist's recent work involves topics such as ruminant nutrition and digestive physiology, meat and animal product quality, fatty acid research and health, reproductive physiology in livestock, and genetic and phenotypic traits in livestock. This body of work emphasizes both the metabolic and physiological dimensions of dairy and livestock production.

J.H. Clark has published in venues that concentrate on dairy science, notably the Journal of Dairy Science. Their notable recent papers include:

  • Functional properties of cream from dairy cows with experimentally altered milk fat composition (2022, Journal of Dairy Science)
  • Production, metabolism, and follicular dynamics in multiparous dairy cows fed diets providing different amounts of metabolizable protein prepartum and postpartum (2022, Journal of Dairy Science)

The scientist frequently collaborates with several researchers in the field. Some of their prominent coauthors include J.K. Drackley, Gerardo Ortiz Gonzalez, Rafael Jiménez-Flores, D.R. Bremmer, and E.J. DePeters.

Throughout their career, J.H. Clark has received multiple awards from recognized professional societies focusing on animal science and dairy science. These include the American Feed Industry Association Award (1980), American Feed Industry Association Award in Ruminant Nutrition Research (1994), Zinpro Award for Excellence in Dairy Science (1998), Award of Honor from the American Dairy Science Association (2000), Distinguished Service Award from the American Dairy Science Association (2002), American Dairy Science Association Fellowship Award (2003), and the AFIA - FASS New Frontiers in Animal Nutrition Award from the American Society of Animal Science (2005).
