Tales From Dead Lambs : Results Of A Survey Of Lambing Losses, Stanley M. Dennis

Journal of the Department of Agriculture, Western Australia, Series 4

During the past year the Animal Health Laboratory has been conducting a preliminary survey into the infectious causes of abortion in sheep and perinatal lamb mortalities. This work was prompted by:

* The diagnosis of vibrionic abortion for the first time in Western Australia in 1961, and

* The estimate that 30 per cent, of all ewes mated in Australia each year may fail to produce a viable lamb that survives to marking time.

This enormous lamb wastage is due to a variety of causes and the role of infectious agents has yet to be evaluated.

Recent Advances In Lupinosis Research, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of the important role which lupins play in light land development, flock losses from the effects of lupinosis must inevitably continue to be a matter of serious concern.

However, research carried out during the last four years has considerably advanced our knowledge of the fundamental nature of this disease and of the way in which it may be prevented or controlled.
