This formation composed of undigested or partially digested plant residues, mucilage, animal hairs, precipitated salts, lime deposit containing phosphoric acid, and other foreign bodies, is in fact a pseudo-stomach stone. As a result of bowel movements, it is compacted, becomes round, gets a polished surface, and a brownish or blackish colour. It occurs especially in the rumen and honeycomb stomach of ruminants (cattle, chamois, bezoar goat), and in size is comparable to either a hen, or even an ostrich egg.call or whapps 08037095551 or call 07052867116
