Mortality Transmitters – New Instrument for Animal Loss Research on Norwegian Ranges
In 1988, 315 lambs from 4 sheep (Ovis aries) herds comprised of 1003 animals were marked with silent mortality transmitters in Gammeldalen in Hedmark County, southern Norway. The aim was to identify causes of death and the so-called “hidden loss” of lambs on summer range. A total of 22 animals, 19 l...
