Reproductive Wastage In Sheep In Non-Clover Areas, C. H. Trotman
Reproductive Wastage In Sheep In Non-Clover Areas, C. H. Trotman
Journal of the Department of Agriculture, Western Australia, Series 4
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

Wimmera ryegrass toxicity has been reported for many years to affect sheep and occasionally cattle in New Zealand, South Australia and the United States of America.
In Western Australia, occasional reports since 1959 and severe outbreaks of staggers in the Katanning- Gnowangerup areas over the last two years prompted the investigation reported below.

Western Australia's 67 per cent lambing for 1970 compares poorly with that of other Australian States, and other countries. From the 12.3 million ewes mated in this State's agricultural areas in 1970, only 8.2 million lambs were marked.
This low 77.7 per cent conception rate sparked the present series of reproductive wastage investigations by the Department's Sheep and Wool Branch.
This report describes the first year's results of the project in W.A.'s "clover disease" areas.
