معرفی
Natalija Fratrić is a Full Professor at the Department of Physiology and Biochemistry within the Faculty of Veterinary Medicine at the University of Belgrade. She teaches multiple specialized courses including Nervous and Humoral Regulation Mechanisms, Physiology and Biochemistry of Body Fluids, Animal Physiology, and Homeostasis of Body Fluids and Electrolytes. Her academic work spans veterinary physiology with emphasis on livestock metabolism and neonatal immunology.
Her research focuses on endocrine and metabolic regulation in dairy cattle, particularly during transition periods and lactation. Key areas include body condition scoring, hepatic lipidosis, thyroid hormone dynamics, immunoglobulin absorption in neonatal calves, and the effects of mineral adsorbents like zeolite on calf immunity. She investigates blood metabolite profiles, hormonal interactions, and stress indicators in high-yielding dairy cows.
Analysis of her 15 most recent publications reveals consistent specialization in bovine periparturient physiology (2013-2016), neonatal calf immunology (2005-2010), and mineral metabolism (2007-2009). Her work bridges veterinary clinical practice with biochemical and endocrine mechanisms, primarily using Holstein and Simmental breeds. Recent studies emphasize in vitro immune function evaluation and metabolic disorder prevention.
Her scientific contributions include co-authoring the textbook Veterinary Physiology (2010) and publishing in journals such as Research in Veterinary Science, Acta Veterinaria-Beograd, and Animal Science Papers and Reports. Her research demonstrates strong collaboration with Serbian veterinary scientists including Dragan Gvozdić, Horea Šamanc, and Danijela Kirovski.
Professor Fratrić maintains active laboratory work focusing on neonatal calf immunity and transition cow metabolism. Her team employs biochemical assays, hormone analysis, and metabolic profiling techniques. Current research trends indicate continued investigation into passive immunity transfer mechanisms and metabolic adaptation strategies for dairy cattle under production stress.
