Reproductive Wastage Among Merino Ewe Flocks. 2. Non-Clover Areas, T Marshall, B. R. Beetson, R. J. Lightfoot, G. R. Mcmullen

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

This research sought to define the reasons for low fertility among Merino ewes in Western Australia.

This first article looks at wastage in Non-Clover areas

Beef Marketing As A Guide To Production Techniques, D J. Barker

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

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …

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.

The Effects Of Changing Flock Structure On The Amount And Type Of Turn-Off From Sheep Flocks, T Marshall

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

In the past the proportion of mated ewes in Western Australia's sheep flocks carried through summer has averaged about 40 per cent and sheep meat production has been basically lamb and old mutton.

If the proportion of mated ewes was lifted to an average of around 50 per cent and wethers were sold off at an average of about 2 1\ 2 years old, there would be substantial increases in sheep meat production. The extra meat produced would be young sheep meat ideally suited for table meats for consumers in W.A. and in many overseas countries.

As a result of …

Development Of A Selective Bait For Rabbits, A J. Oliver, S. H. Wheeler

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

It has long been recognised that a means of killing rabbits selectively in the presence of stock would be a major advance in rabbit control. It would enable a whole farm to be treated for rabbit control at one time, saving operational costs and cutting down reinfestation of rabbits into treated areas from untreated areas.

A literature search and some pilot trials indicated that indandione derivatives were more toxic to rabbits than to ruminants.

Pindone (2- pivalyl-l,3-indandione) was selected for evaluation.

The Medina Pig Research Station, Department Of Agriculture, Western Australia

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

Before the Department of Agriculture's Medina Pig Research Station was established in 1964, pig production research had been carried out on Denmark Research Station, Muresk Agricultural College and in some commercial herds.

However, with increasing specialisation in the pig industry better facilities were needed. Medina Research Station provides such facilities, allowing it to carry out research to provide detailed information of immediate practical value for both extensive and intensive pig production enterprises.
