Description: In response to industry demand for enhanced biosecurity and welfare during animal transport, a prototype air-filtered swine trailer was developed. The prototype trailer has a front compartment that houses the air filtration and ventilation system, and a 20-ft animal compartment with solid aluminum walls, two decks, and a hydraulic lift gate. This study aimed to evaluate the overall trailer performance, conduct an economic analysis, and implement modifications for optimization of the trailer design. The efficiency of the installed air filtration system (MERV 8 panel pre-filter and MERV 16 glass fiber V-bank filter) was evaluated in stationary tests with no pigs inside the trailer. Upstream and downstream monitoring of concentrations of aerosolized model virus (bacteriophage Phi X174) yielded an overall filtration efficiency of 96.9%. Moreover, two monitoring trips with market-sized pigs loaded in the trailer showed a general front to rear movement of air as evidenced by increasing trailer temperature, moisture, and CO2 levels from front to rear end of the trailer. Conditions at the middle to rear portion of the animal compartment were within acceptable thermal limits. However, locations at the front end of the animal compartment experienced low temperatures (<10?C) during portions of the trips. Cost analysis for a 120-pig capacity air-filtered trailer yielded an estimated total cost of $109,900. Assuming an incremental revenue of $5 per head of biosecure pigs transported, the estimated payback period was about 2.41 years. Implemented modifications to the prototype include installation of water drinkers, misters, interior lighting, and improved ventilation control system.
