There is some evidence from the University of Nottingham by professor J Neave that the contractions of the omasum can propel large particles backwards through the reticulorumen orifice, the junction connecting the omasum with the reticulorumen, into the reticulorumen, the first compartment of the ruminant stomach.

Denser, small particles stay in the ventral reticulum during reticular contraction, and then during the next contraction may be swept out of the reticulorumen with liquid through the reticulo-omasal orifice, which leads to the next chamber in the ruminant animal's alimentary canal, the omasum.

In this way, the omasum allows large particles, which still likely contain appreciable amounts of fermentable substrate, to be further digested in the reticulorumen . ( Though fermentation initiated in the reticulorumen can continue in the omasum, it does so in only limited quantities, so this mechanism of ejecting largely unfermented particles into the reticulorumen is necessary for complete fermentation .)

When Andriamampandry was about to leave, the prince returned the rope and axe, gave him the basket of fine meat for his wife, and gave him the second basket, declaring " These are the parts for the axe ( i . e . the neck ) and the rope ( i . e . the striated omasum ) . " Andriamampandry was deeply impressed by the hospitality and foresight of the prince.
