The influence of nutrition and seasonal conditions on mineral status in the reindeer
Body weight, serum sodium, potassium, calcium, magnesium, copper, and zinc concentrations, and alkaline phosphatase (EC 3.1.3.1) activity were measured in freely grazing reindeer in Kuusamo, Finland (66°30′N), at four different seasons in the year. The same parameters were also measured in late wint...
