Each year the Dairyland Initiative in Wisconsin holds workshops to train veterinarians, building contractors, equipment suppliers and producers to design, install and operate successful positive pressure tube ventilation (PPTV) systems for calf housing. The Wisconsin system has very particular parameters that lead to success. This year the one day workshop will be held in Elora on January 14th, 2015. Pre-registration is required. For more information please see the attached flyer.
