KEYWORDS
ABSTRACT
A new method for recording jaw movements (JM) oscillations (JMO) in sheep is described. The
principle used to record JMO is the changing position of the magnetic field from a magnet relative
to a small Hall sensor, when both were positioned in a soft tube surrounding the mouth. The signal
was sampled at 20 Hz by a logger hanged in a wheel joint allowing the sheep to move around freely
in a small pen. The individual JM were identified and clustered into cycles. Recorded JMO, JM and
cycles are presented from an ewe eating and ruminating grass silage.
