[Retention of large-size particles in the reticulum of the cow].

Abstract

To explain the retention of large particles in the reticulum, in vitro sedimentation, sorting of particles by gas production and flow of contents through a hole simulating the reticulo-omasal orifice (ROO) were examined. Removal of large particles from the floor of the reticulum by gas production and a sieving mechanism through the ROO are discussed.
