Functional Anatomy of the Omasum in High Arctic Svalbard Reindeer (Rangifer tarandus platyrhynchus) and Norwegian Reindeer (Rangifer tarandus tarandus) [PDF]

open access: yesActa Veterinaria Scandinavica, 2000
The structure and fill of the omasum was investigated in summer and in winter in adult female reindeer living on the polar desert and tundra of the high Arctic archipelago of Svalbard and in sub-Arctic mountain habitats in northern Norway. The mean total mass of the omasum in non-lactating adult female Svalbard reindeer was 467 g (0.65 g per 100 g live
