A livestock force tub features a perimeter structure delimiting an interior space of said livestock tub, including a main peripheral wall spanning circumferentially around a central upright axis, an exit situated at or proximate a terminal end of the main peripheral wall and a supplemental wall section at an area adjacent the exit on a side thereof opposite the terminal end of the main peripheral wall. The supplemental wall section increases an angular span of the tub around the central axis to create an auxiliary space beyond the exit. This auxiliary space accommodates a possible uncooperative animal during unloading of the force tub while allowing others to still reach the exit. The supplemental wall section and a terminal section of the main peripheral wall have a lesser opacity than more significantly cladded areas of the main peripheral wall, whereby increased light admission and environmental visibility attract livestock toward the exit.
