Variation in ruminal nitrogen levels among some cervidae
Among black-tailed deer (Odocoileus hemionus sitkensis), roe deer (Capreolus capreolus), and reindeer (Rangifer tarandus), nitrogen levels in the contents of the rumen show consistent patterns of variation. Among deer of each species on the same range during the same season, the animal-derived nitro...

Among black-tailed deer (Odocoileus hemionus sitkensis), roe deer (Capreolus capreolus), and reindeer (Rangifer tarandus), nitrogen levels in the contents of the rumen show consistent patterns of variation.
