Calving of the experimental reindeer herd in Kaamanen during 1970 - 85
Calving and calf production were studied in an experimental reindeer (Rangifer tarandus L) herd in Inari, Kaamanen (69°10'N) in northern Finland. Most of the calving took place between May 10 and 29; 50% of the calves were born up to 22.5. and 90% up to 29.5. The percentage of calves (calves/hi...
