Description: Airborne diseases can cause significant economic losses to the Canadian swine industry through actual loss in animal productivity, added costs of medication and eradication measures, and even potential loss of access to markets for Canadian pigs. Recently, another disease, Porcine Epidemic Diarrhea (PED), has emerged as a serious threat to the industry. Although PED is not known to be transmitted airborne, contaminated transport trailers were identified as one of the main routes for spreading the PED virus. Hence, the main goal of this project is to develop an improved design for transport trailer that will facilitate control of airborne pathogen contamination, improve operational efficiencies, and address the biosecurity threat posed by transport trailers. Initial design of the trailer was developed based on inputs from stakeholders and was further refined by computer simulation using a computational fluid dynamics (CFD) modeling. Various ventilation design configurations based on number and location of air inlets and outlets on the trailer were simulated under Saskatchewan conditions. Based on heat removal efficiency (HRE) and thermal condition predicted inside the animal compartment, the best design configuration was selected for sensitivity analysis. Results indicated that a 5-kW heating system and a water misting system are required to keep the thermal conditions inside the trailer within the animal comfort zone when outside temperature is below -10
