The Office of the City Veterinary and Agricultural Services or OCVAS came about in 1993, when employees from the national government under the Department of Agriculture were devolved and became the pioneering staff of the then Office of the City Agriculturist. It was the latter part of that same year that its name was changed to OCVAS, and was headed by its newly appointed chief, Dr. Loyola C. Bagui.
Four years later, in 1997, the Department transferred to its new building, with all its 6 divisions: the administrative, cooperative, crop production, fishery, home extension and livestock divisions, all working together to achieve its mission to empower the farming and fishing communities and the private sector to produce sufficient, accessible and affordable food for every Batangueño, and provide them with competitive livelihood that will generate a decent income for all.
In 2008, two more divisions were formed to further enhance and broaden the scope of services of the Department, the Agricultural Engineering and the Research and Development Communication Divisions.
OCVAS also visualizes a modern agricultural and fishing community that is dynamic, technologically advanced and internationally competitive whose transformation is guided by the sound practice of resource sustainability, unassailable principles of social justice and zealous participation of the private sector.
