OverviewAI-generated summary
Brittni P. Littlejohn's research focuses on understanding physiological and molecular responses in livestock, particularly cattle, to various environmental and physiological stressors. Her work investigates the role of DNA methylation patterns as potential biomarkers for stress and health in mature Brahman cows, examining its correlation with stress axis tissues and its presence in peripheral blood leukocytes. She also studies the impact of maternal nutritional status and environmental factors, such as endophyte-infected tall fescue, on fetal development, uterine hemodynamics, and offspring growth performance. Her publications explore interventions like melatonin supplementation to mitigate negative effects during pregnancy and development. Littlejohn has published 63 works with 168 citations and an h-index of 7. She collaborates with researchers from the University of Arkansas at Fayetteville, including Jeremy G. Powell, C.R. Looney, E. B. Kegley, and Doug L. Galloway.
