Current state of and prospects for selection in reindeer husbandry

Reindeer husbandry is highly valued in Finland. Nevertheless, the profitability of reindeer herding could be improved. Limited pasture resources restrict the opportunities for increasing the number of animals per area; hence, the focus should be on higher quality. Selection of breeding animals could...

The calf traits had direct heritability values of 0.23-0.27, while birth weight and growth also showed maternal heritability values of 0.18-0.24.
