Bulletin No 3863 - Plants Which Cause Kimberley Horse Disease, A. L. Payne

Bulletins - 3000 - 3999

Crotalaria crispata and Crotalaria retusa (Rattlepod), two plants responsible for Kimberley horse disease*, are, unfortunately, fairly widespread throughout the Kimberleys. Both species are apparently toxic in all stages of growth.

This bulletin is to assist pastoralists to:-

• Identify the two plants;

• Recognise the type of country and conditions under which they grow; and

• Locate horse paddocks on country where the plants are least likely to occur.

Annual ('Wimmera') Ryegrass Toxicity, Geoffrey A. Pearce, O. M. Goss, P. H. Berry, J. L. Wise

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

Because annual ryegrass is one of the most widespread pasture plants in Western Australia, annual ryegrass toxicity is a threat to livestock in many agricultural areas—even though the area now affected is small.

The problem is being intensively studied by the Department of Agriculture and a working group has been set up to investigate potential control measures.

In this article the group reviews the problem and reports progress in its investigations to the end of 1973.

Wimmera Ryegrass Toxicity, Department Of Agriculture, Western Australia

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

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.

Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones

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

WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.

Cyanogenetic Plants Of Western Australia, T E H Aplin

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

THIS article deals with the more important cyanogenetic plants found in Western Australia.

It also deals with plants which have not been proved as cyanogenetic but which do produce toxic effects similar to those produced by cyanogenetic plants.

Symptoms, post mortem appearances and the treatment for affected stock are also dealt with.

Chemical Poisoning In Animals. 3. Prussic Acid, H D. Seddon

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

HYDROCYANIC or prussic acid poisoning is a serious and not uncommon ailment of ruminants, and may be a cause of rapid death when pasture plants capable of developing dangerous levels of the poison are being grazed.

Bulletin No 69 - The Poison Plants Of Western Australia, D. A. Herbert

Bulletins 1 - 2999

Up to the present no publication dealing with the whole of the known i)01S0fl plaits of Western Australia has been written. This Bulletin contains the collected accounts of various authors and correspondents which have been published at different times and contains a large amount of original information gathered both from field experience and from laboratory experiments. The work is not complete. A number of plants from distant districts have not been obtainable or obtainable only in amounts insufficient for exhaustive tests. These plants are comparatively few, however, and in Section 13 of this publication those which are suspected, but against …
