Abstract
With the advent of African Swine Fever, biosecurity requirements during transportation have become increasingly stringent. Vehicles transporting pigs between large-scale farms are increasingly adopting fully enclosed air-filtered trailers, significantly reducing the risk of viral infection during transit. However, due to the complete sealing of the cargo compartment, insufficient ventilation or excessive internal temperatures can easily lead to pigs suffocating. This study focuses on air-filtered pig transport vehicles, simulating and experimentally analyzing the internal airflow and temperature distribution. Results indicate relatively high temperatures and slow airflow at the rear of the compartment. Corresponding optimization designs for the vehicle interior are proposed to address this phenomenon.
