Dear Richard, The undigested solid matter in the dung is in fact the lignocellulosic matter, However, in the case of ruminents, it is not in a fibrous form but in the form of particles due to the practice of chewing the cud. It is the dung of non-ruminents, like horses and elephants that has fibres. Yours A.D.Karve
