First paragraph (this article has no abstract)

The frequency of stillbirths in flocks registered in the Norwegian Sheep Recording System (NSRS) is increasing. In 2001, 3.4% of born lambs were registered as stillborn, in 2006 the number had increased to 4,1%. Some farmers also report seeing more lambs that are weak at birth and die within a few hours. Post mortem examinations are not frequently carried out, unless there are large losses in the flock. The causes of stillbirths and death in weak lambs are thus to a large extent unknown in the "average flock". On this background, a study was carried out during the lambing season 2006, in order to identify causes of perinatal death in 9 herds in Oppdal and Rennebu in the county of Trøndelag.
