Digestion of energy and nutrients in Svalbard reindeer
Feeding trials with 5 male Svalbard reindeer, Rangifer tarandus platyrhynchus Vrolik were conducted at the Man and the Biosphere (MAB) Research Station in Adventdalen, Svalbard. Five different diets were used, 1: commercial reindeer food, (RF-71), 2: a mixture of locally harvested grasses and sedges...
