Yet, there are still some trucking companies forcing the cattle to jump to and off the truck due to lack of ramps. Ramps are usually built from locally available materials.
Thereupon, the pneumatic suspension system plays a big role as well in stress reducement. Most cattle trailers come with a factory-installed pneumatic suspension. The transportation over smoother roads decreases the stress as well.
In the first place, cattle trailers in the USA are manufactured with a variety of perforation patterns. These perforation patterns are used for ventilation.
Most commonly the perforation patterns are featuring roof hatches that can be opened with the aim to increase the ventilation.
Usually, the ventilation within these types of trailers is passive and can result in non-uniform air circulation at the animal head level.
Truck drivers should be especially careful about this because the heat can build up rapidly in the stationary vehicle.
