Influence of papillae on post‐ruminal regulation of ingesta passage in moose ( Alces alces L.)
Abstract The variable keratin appendages of the forestomach epithelium on both sides of the reticulo‐omasal orifice, emerging in early summer and disappearing towards the winter in the moose Alces alces L. were studied. During the study period, droppings of the free‐ranging moose were collected rand...
