Effect of moderate wintertime undernutrition on fatty acid composition of adipose tissues of reindeer (Rangifer tarandus tarandus L.)
We studied the effect of moderate undernutrition on the fatty acid composition of adipose tissues in reindeer calves (<1 year) between early winter and late spring. Calves studied in early winter (December) had grazed on natural pastures and were in good condition, while the calves in spring (Apr...
