Nothing. It will just get digested in the rumen and other three stomach chambers then get passed out as waste in the form of feces.
This is exactly what happens when cows get what is called "bloat." A cow that cannot release gases built up in the rumen will die because of the intensifying pressure the rumen puts on the lungs, strangling the cow to death. So to answer your question, the cow would die.
Yes a sheep's stomach has four compartments, the rumen, reticulum, omasum and abomasum.
The rumen.
Rumen degradable protein (RDP) is feed protein that can be broken down by microbial enzymes in the rumen (neutral pH) where the resulting nitrogen, AA's or peptides are either utilized to meet microbial requirements or if unused, ammonia which is absorbed across the rumen wall and either recycled or excreted. Look up P. J. Van Soest "Nutritional Ecology of the Ruminant" in googlebooks for a more detailed description.
It will die as it needs a rumen to digest its food properly.
A rumen fistula is a surgically created entry to the rumen in the left flank of the ruminant, typically permanent and with a rubber or similar material device (a 'cannula') fitted to close it between times of use. It enables the rumen contents to be accessed, and the rumen wall to be viewed and biopsied. Surgically modified ruminants such as these are only found on research farms, where they are used to study rumen function. Looking in through the fistula, you can see the rumen contents and the rumen wall.
