High protein pastures in spring - effects on body composition in reindeer
In 1996 and 1997 three groups of reindeer from different nutritional origin and condition, (poor condition groups n=15 in 1996, n=7 in 1997, good condition group n=10 in 1997), were used to investigate effects of high protein pastures on body condition for 3.5 weeks in spring. Mean body mass (BM) of...
