Students in the Agricultural Mechanics and Welding programs at Champion High School have built a mobile dipping vat semi-trailer designed to help fight threats to the nation's cattle industry.

Under instructor Dorman Vick, students recently completed the 2,200-gallon unit, built to help fight the New World screwworm and fever ticks, two biosecurity threats to livestock.

The project used 331 pages of computer- aided design blueprints and five documentation binders.
