Macrominerals in free-ranging Swedish reindeer during winter
Samples of blood, rumen, and caecal contents were taken from 238 reindeer (Rangifer tarandus) slaughtered between September and March in two consecutive years. Levels of magnesium, calcium and phosphorus were measured to evaluate the extent to which levels of these minerals reflected changes in the...
