正本に書いてある決まりごと
A behaviour diagram drawn in plan.
Every dimension on this sheet comes from what cattle will and will not do.The race curves because cattle head back toward where they came from -the curve uses that instead of fighting it.
It is not a trick. An animal standing in the crowd pen still has to seetwo body lengths up the race; if it cannot, the entrance reads as a wall andnothing moves. That is also why a tight radius needs a straight section first.
Sides are solid for the same reason: what they see beside them stops them.The crowd pen is level, and any ramp belongs inside the single file race.
1 px = 2 in. Dimensions follow published handling-facility guidance(Grandin, "The design and construction of facilities for handling cattle",grandin.com, retrieved 2026-10-02: race 66-71 cm, V race 41-45 cm / 81 cm at 152 cm,radius 3.5-6 m, under 3 m needs a 3 m straight, crowd gate 3.5 m); this layout is fictional.
