Professor — Animal Breeding and Genetics

Dr. Toni Oltenacu is a professor in the Department of Animal Sciences at University of Florida and Professor Emeritus in the College of Agriculture and Life Sciences at Cornell University. For the past forty years, he has been active in teaching, research and outreach programs. He has taught courses in animal breeding, animal production, equine genetics, canine genetics, decision analysis, risk analysis and systems analysis.


  • Research

    Research Summary

    Dr. Oltenacu’s major objectives of his research have been to quantify the environmental, management and biological (including animal’s genotype) factors on health and welfare of farm animals for a variety of herd environments and production practices. In his research he has used mathematical modeling to describe the behavior of the biological systems and evaluate the impact of various management practices, epidemiological tools to quantify risk factors for health and welfare of animals, decision analysis to rank management interventions. Dr. Oltenacu has adopted a system approach that integrates animal health with welfare and production throughout his research career. This approach generates the type of information needed to develop decision support systems, to prioritize the emphasis to be placed on health, welfare, fertility and longevity in the management programs of the dairy cows or other livestock at the farm level. This approach to research also provides additional support to the ongoing transition from the classical animal health program with emphasis on clinical diagnosis and therapy to a more preventive animal health program based on risk assessment.

    ANS 2005, The Role of Animals in Human History

    Course Overview

    The course surveys the importance of animals through human history, from the prehistory to the present. The domestication of dogs, cats, major farm animals and some less familiar, such as camels, reindeer and buffalo and the role they played in different societies and cultures is discussed.
