Autopsies were performed on lamb carcasses from 2 groups of Merino ewes lambing in paddocks in spring 1978 and from 1 group lambing in pens in 1980 in south-west Queensland. These showed that the main causes of death were starvation due to failure of the lamb to obtain milk, problems at parturition causing death during or shortly after birth and, in some cases, predation. The results are similar to those found by workers investigating perinatal lamb mortality in other areas. Their significance is discussed in relation to Merino sheep flocks in south-western Queensland.
