to the rumen contractions by placing your stethoscope in the left
paralumbar fossa. Normal rumen contractions (1-3/minute) are
strong, and can be felt and seen. Palpate, auscult, and ballot the
rumen to assess consistency. A gradation in consistency exists
from the dorsal to the ventral sac of the rumen. The dorsal sac of
the rumen generally has a gas cap and becomes more doughy in consistency
(feed layer) towards the ventral fluid-filled sac of the rumen. A
rumen ping is differentiated from an LDA ping by its location over the
left paralumbar fossa. It is possible to have a rumen ping and an
abomasal ping at the same time, but they generally have different tones.
If a ping with the same tone extends over both the rumen and the
abomasal area, and rectal examination reveals a very small rumen with a
distended gas-filled dorsal sac, the ping is most likely a rumen void
