The close confines of transport trucks can make herding pigs challenging, but by watching the herd’s reaction and using their instincts loading and unloading can become much smoother. When feeling threatened, pigs will seek safety and do so in several ways. If the pigs are calm, the herd will move in a flow. As the pigs feel more threatened bunching or circling can occur. When unloading or loading pigs, the flow herd movement is desired. It is important to keep the pigs calm and to stay out of their flight zone. Transporters also need to control their own instincts to chase, or use too much  pressure to get the animals moving. By paying attention to physical cues, moving pigs can be made much smoother by keeping the herd calm and using their natural herd instinct.
