title: Moose milk and hair element levels and relationships.
abstract: Milk was collected from 21 Alaskan moose (Alces alces gigas) at the Kenai Moose Research Center (MRC), Soldotna, Alaska nad analyzed by atomic absorption spectroscopy for Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Se and Zn. Hair samples were collected from 100 moose at the MRC to correspond with the lactation period and serve as a metabolic indicator of mineral elements stored in tissue. Published analyses of bovine milk were compared to moose milk; Al, Fe, Se and Zn were higher in moose milk by factors of 1.6 to 290. Elements potentially influenced by nutrition and those determined genetically were also  considered. Elements in moose milk and hair values were compared, since mineral element levels in hair potentially reflect the availability and intake of these elements. Calcium and Mg were the only values in hair lower than the values in milk (factors of 4.2 and 1.5 respectively). Moose, as well as domestic cattle, apparently are subjected  to lactation stress by the genetically determined levels of Ca and Mg in milk.
