Though they mainly live in the wild, some moose have been domesticated. Farms in Russia raise the animals, not for their meat, but for their milk. Moose milk contains more butterfat than cow milk. At the same time, however, it has more beneficial nutrients, including high concentrations of zinc, selenium, iron and powerful enzymes that traditional medicine practitioners believe can heal some gastrointestinal problems.
The milk moose are only semi-domesticated. At one farm in Kostroma, Russia, they are free to graze in the surrounding forests for most of the year. They only lactate for a short period during the summer when their young are born. During this time, the moose are milked twice per day, and the daily yield averages a half-gallon. Though they are free to roam, the large mammals are tame enough to come when called (which is often done over a loudspeaker).
