The ovulation rate, or the number of eggs shed per ovulating ewe, represents the upper limit of the capacity of a flock of ewes toproduce lambs. Several methods can be used to increase ovulation rates and lambing percentages of ewes, including selection for better breeding, feeding and the use of chemicals.
The potential for improving the reproductive performance of Western Australia's ewe flocks by the use of different approaches to breeding was discussed by L.G. Butler and R.P. Lewer in the Journal of Agriculture in 1983.
This article mainly discusses the research conducted by the Department of Agriculture's Sheep and …

A Research Round-up report in the June, 1972, issue of the Journal of Agriculture discussed the reproductive performance of sheep in Western Australia and indicated that more than 20 per cent, of mated ewes fail to lamb.
The report presented the first year's results from sheep grazing clover areas.
This report presents results from the nonclover sections of the investigations
