Research and teaching of dairy cattle well being: finding synergy between ethology and epidemiology.

Epidemiology is a tool used to identify and quantify risk factors that contribute to the state of health or disease. In addition, the maintenance of health and recognition of nonhuman animal welfare are both key principles of health management. Animal welfare and ethology provide important contributions to our ability to understand and improve health. As such, there can be a strong connection between the disciplines of ethology and epidemiology. This connection becomes a synergy through collaborative research. At the University of Guelph, and at other institutions, dairy health management research efforts involving collaborations between faculty trained in ethology and epidemiology have led to refined and improved research programs, improved access to funding, and a broader extension audience. Furthermore, these collaborations have enhanced teaching programs and facilitated the integration of ethology and welfare topics throughout the veterinary medical curriculum. The paper provides the basis and context for the synergy between ethology and epidemiology and describes examples of teaching and research programs built upon this synergy for the enhancement of dairy cattle well being.
