Re-Thinking The Summer Drenching Program, Brown Besier

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

The summer drenching program has provided highly effective sheep worm control in Western Australia for many years - but recent research challenges its long term sustainability.

Trial results suggest that in large parts of the State, summer drenching is the main factor leading to the development of drench resistant worms. Alternative programs less likely to lead to drench resistance will require greater monitoring of worm burdens and panning pasture moves.

Yellow Lupins For The Pig Industry, Bruce P. Mullan

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

There is no doubt that Yellow lupins are suitable as an ingredient in the diet of pigs from weaning through until slaughter. While no research has been conducted on feeding this variety to breeding stock, there is no reason to believe that it would not be a suitable source of energy and amino acids. Whether it will become a significant ingredient in pig diets will depend on its availability and price.

Investigating Teeth Eruption And Eating Quality, Sarah Weisse, Rob Davidson, Brian Mcintyre, David Pethick, John Thompson

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

In Australia, a sheep ceases to be a lamb as soon as the eruption of its first permanent incisor teeth is evident. As part of a wider program to investigate a number of aspects of sheep meat eating quality, a project was undertaken to determine whether lamb eating quality would be compromised if sheep with partially erupted teeth continued to be classified as lamb.

Overall, the results indicated that meat from young sheep with partially erupted teeth was unlikely to be inferior in eating quality than the meat currently classified as lamb.

Ofda2000 Brings Major Changes For Wool Industry, Andrew Peterson

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

The classing of any wool clip into lines of uniform quality is a crucial step in optimising the value of the wool. Objective Clip Preparation (OCP) standards and training of wool classers lave led to the Australian wool clip being internationally recognised as the best classed and prepared wool in the world. However, adherence to OCP standards of clip preparation still leads to a substantial range in diameter and crimp frequency of fleeces within the main lines. Therefore, an opportunity has existed to develop improved technology to reduce the variation in quality within any main line, create lines of even …

Improving Feed Grains, Bruce P. Mullan

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

Clearly, to encourage grain growers to focus their production systems towards feed grains, it is important to first identify the reasons for variation in the nutritional value of grains and then to develop rapid, cheap, and accurate methods of measuring these factors. The analytical methods should ideally be suitable for application either at the site of grain delivery from the farm or within the place of stockfeed manufacture. This will mean the nutritional value of the grain can be known before it is used. The rational marketing of feed grains could then be achieved, with the benefits from more efficient …

Eradicating Virulent Footrot From Western Australia, R K. Mitchell

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

Western Australia has a unique opportunity to eradicate virulent footrot from the State's sheep flock, with only 62 properties or 0.6 per cent of sheep properties currently in quarantine. The majority of Western Australian flocks are now free of virulent footrot, with targeted on-farm and abattoir surveillance used to detect the remaining properties affected by the disease. Bob Mitchell reports on how farmers, industry, and government are working together, with research playing an important part in the eradication campaign.

Uht Milk : Expanding The Market, Caroline Love, Ian Bell, Martin Robertson

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

An increase in the export of UHT (Ultra Heat Treated) milk to Asian markets is potentially worth millions of dollars to the dairy inmdustry. This increase however, relies on the shelf life of UHT products being extended to nine months. Spoilage of UHT milk can be caused by bacterial spores which originate on-farm and are resistant to processing. Expansion in the UHT market therefore relies on a continued reduction in the number of these spores getting into raw milk. Caroline Love, Ian Bell and Martin Robertson report on the sources of spores entering milk on-farm and the control methods available.
