Calf mortality in semi-domestic reindeer (Rangifer tarandus) in a Scottish herd: the impact of maternal age and individual differences between cows
High calf mortality rate is a significant problem facing semi-domestic reindeer (Rangifer tarandus) production around the world. Mortality rates, commonly due to predation, can range from 5 to 70%, which constitutes a great welfare concern.
