Foreign objects in rumen
Indigestible objects which are occasionally swallowed without proper mastication pass to the rumen. If the surface of the piece is sharp, it causes inflammatory reaction in the mucosa of reticulum and rumen.
This leads to infectious spread on pericardium, peritoneum or pleuaral membrane (Traumatic Reticulo Peritonitis and Traumatic Pericarditis).
High density material pass via cranial sac, sink to the floor of the cranial sac.
Heavy indigestible objects always remain in the floor of reticulum as reticulo- omasal orifice lie dorsal to the floor of reticulum.
