• This truck loading/unloading facility has the dock elevated to truck height.

      

• For all species, a plant should have sufficient unloading ramp capacity so trucks can be unloaded promptly. In large plants, at least two and preferably three ramps are required. Unloading ramps should have a level dock before the ramps go down so that animals have a level surface to walk on when they exit the truck. The slope of the ramp should not exceed 20 degrees. On concrete ramps, stair steps are recommended because they provide better traction than cleats or grooves when ramps the become dirty.

• For cattle, the recommended stair step dimensions are 3 1/2 inch (9-10cm) rise and a 12-inch (30cm) long tread. If space permits, an 18-inch ( cm) long tread will create a more gradual ramp. For pigs, a 2 1/2 inch (6.35cm) rise and a 10-inch (25cm) tread works well. On adjustable ramps, cleats with 8 inches (20cm) of space between them are recommended. Ramps for small piglets will need much closer cleat spacing ( 3 inches/ 8cm). All flooring and ramp surfaces should be non-slip. Many animals are injured on slippery unloading ramps.

• This design is for loading livestock. The cattle walk in a single file line and the ramp width is 30 inches (79cm).

Pigs move more easily through a ramp where they walk up side by side. The outer sides are solid and the middle partition is "see through" to promote following

• On the diagrams illustrating well designed pig races, the double chute is recommended. However, if space restriction is an issue, notice that the diagram without the entire double chute does promote pigs natural following behavior and prevents jamming with an offset step at the entrance of the chute. With the double chute design, the outer walls are solid, with a "see through" middle partition that further promotes following behaviour.

• Two examples illustrating options in layout designs for pig handling facilities  and/or ranches.
