Nose twitch
The nose twitch consists of a wooden stick - sometimes made of plastic - of
about 50 cm with a hole at one end through which a loop of rope
(exceptionally a chain) protrudes. The tool is used as a means of coercion
to divert the attention of a horse during disturbing (eg eye care) or
painful procedures and to induce a calming and sedative effect (cf. humane
twitch). With the left hand, the loop is brought over the upper lip of the
animal, with the right, the loop is tightened. The same implement is used
on cattle, but on an ear (1). [MOT] (1) BERTHELON: 13.
