Graph showing the effect of rubber ring castration on the posture of lambs

Note how the whole of the lamb's time is spent in abnormal postures, with abnormal lying postures with full extension of the hind legs dominating the behaviour for at least one hour. Lying with partial extension of the hind legs dominates more as the severity of the pain changes (after the first hour).   'Statue' standing is also observed more frequently at this time after this method of castration.
