Although reproductive rates vary greatly between individual properties, the average marking percentage in Western Australia still hovers around 75%. In the absence of disease it is possible to improve on this figure by undertaking some straight forward management practices at different stages of the reproductive cycle.

Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.
It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.

Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon
Journal of the Department of Agriculture, Western Australia, Series 4
Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.
Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.
