Overview

C.G. Schwab is affiliated with the University of New Hampshire in the United States and conducts research primarily in the fields of Agricultural and Biological Sciences and Biochemistry, Genetics and Molecular Biology. Their work spans several subfields, including Agronomy and Crop Science, Genetics, Pediatrics, Perinatology and Child Health, Nutrition and Dietetics, and Cell Biology. The scientific focus is notably oriented towards ruminant nutrition and digestive physiology, reproductive physiology in livestock, genetic and phenotypic traits in livestock, birth, development and health, infant nutrition and health, and muscle metabolism and nutrition.

The scientist has contributed to multiple publications in peer-reviewed journals and other academic venues. Recent papers include:

  • "Effects of rumen-protected methionine supplementation on the performance of high production dairy cows in the tropics," (2021) published in PLoS ONE
  • "Balancing dairy cattle diets for rumen nitrogen and methionine or all essential amino acids relative to metabolizable energy," (2023) published in the Journal of Dairy Science
  • "Assessment of blood sampling time points to determine the relative bioavailability of ruminally protected methionine supplements using the plasma free amino acid dose-response technique," (2024) published in JDS Communications
  • "Effects of rumen-protected methionine supplementation on the performance of high production dairy cows in the tropics," (2020) published in bioRxiv (Cold Spring Harbor Laboratory)
  • "Influence of Dietary and Ruminal Factors on Microbial and Non-Microbial Nitrogen Flows to the Small Intestine in Lactating Dairy Cows: A Meta-Analysis," (2025) published in Dairy

C.G. Schwab frequently collaborates with colleagues in the field. Notable co-authors include:

  • Valdir Chiogna
