PTS. The New Industry Standard In Poultry Transport. Introducing the PTS Atmosphere Optimizing Trailer (AOT), a product so revolutionary in its design and performance that it is already changing the poultry industry. The key is where we started: we didn't just retrofit existing components, like current options. We started from scratch and engaged master craftsmen & animal scientists to solve all previous issues. After years of development and hundreds of live hauls, we're confident the AOT is ready to become the new industry standard for poultry transport. In fact, one USDA inspector who toured an early model said exactly that.
