Veterinary Science theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias.

Veterinary medicine's ultimate purpose is to promote, maintain and restore the health of animals, people and the ecosystems which they inhabit. The theme on Veterinary Science focuses on ensuring the health and welfare of animals and provides the essential aspects and a myriad of issues of great relevance to our world such as Veterinary Medicine; Veterinary Surveillance; Metabolic Disorders of Dairy Cattle; Veterinary Pathology; Veterinary Toxicology; Comparative Immunology-Based Approaches to Veterinary Diseases; Veterinary Virology; Veterinary Bacteriology; Veterinary Mycology; Veterinary Helminthology; Biology of select zoonotic protozoan infections of domestic animals; Veterinary Ectoparasitology. This volume is aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Craig Stephen obtained his DVM degree from the University of Sasktachewan in 1987. After 4 years of private veterinary practice in a rural mixed animal practice, Dr. Stephen entered a doctoral program in epidemiology at the University of Saskatchewan where he focused on field epidemiology and disease outbreaks as the theme of his research.
