Arch-soil characteristics

Pigs are born with the genetic characteristics of arching soil, and arching soil for food is a remarkable feature of pig feeding behavior. The pig's nose is a highly developed organ, and the sense of smell plays a decisive role in digging the soil to find food.

Although in modern pigsty, pigs still show the characteristics of arch foraging. Every time they eat, they try to occupy a favorable position in the trough. Sometimes, they use their forelimbs to step in the trough to eat. If the trough is easy to approach, some pigs even get into the trough and stand in the corner of the trough, just like wild boar arching for food, arching along the trough with a kiss and stirring the food all over the floor.
