To achieve efficient milk ejection has been a recurrent problem in machine milking of reindeer does. The field season 2004 was a breakthrough for an efficient and complete milk let down in reindeer. The proportion of residual milk was reduced as lactation progressed; from around 40-50% at start of the milking in mid June to around 10-15% in late August, suggesting that habituation and training are important factors for triggering the ejection. We performed an experiment including 3 treatments; 1) Calves equipped with a "kjevle" (a wooden stick placed in the mouth of the calves making them unable to suckle but keeping their grazing ability intact) for 8 - 14 hrs dependent of lactation stage, followed by milking of the does, 2) Physically separation of the mothers and their calves for 8 - 14 hrs dependent of lactation stage, followed by milking of the does and 3) Permanent separation of females and calves at start of the milking period and females milked twice per day.
