: Fifteen lambs from a flock of 1000, 5-month-old Romney lambs in the Manawatū region of New Zealand, developed unusual postural and gait abnormalities during the Summer of 2020. In mid-January, the lambs were grazing a raphanobrassica crop ) but were removed from this crop soon after as they developed dermal lesions on the pinnae consistent with photosensitisation (colloquially known as 'rape scald'). The lambs were placed onto a shaded paddock containing a pasture of predominantly perennial ryegrass () and white clover (). One week following removal from the crop (late January), the 15 lambs developed abnormal postures and gaits that were described by farm staff as 'neurological' and 'swayback-like'.
