Relationship of dietary browse to intake in captive muskoxen.
The effect of dietary browse (Salix bebbiana Sarg.) on intake and activity of muskoxen (Ovibos moschatus Zimmermann) pastured in south-central Alaska was compared to animals on grass pasture only. In previous work, intake increased in penned animals fed increasing browse: hay rations, which presumab...
