Land Capability And Land Use In The Leeuwin-Naturaliste Region, Peter John Tille, Neil Lantzke
Land Capability And Land Use In The Leeuwin-Naturaliste Region, Peter John Tille, Neil Lantzke
Journal of the Department of Agriculture, Western Australia, Series 4
The Leeuwin-Naturaliste region is one of Western Australia's most beautiful areas. Located in the far south-west corner of the State, it is a popular scenis and tourist spot, as well as supporting grazing, horticultureal and viticultural enterprises.
Outside of perth the region is the most popular tourist destination in the state. It is also responsible for about a quarter of the State's milk production, and 15 percent of the state's potato production and a quarter of the State's wine grapes.
Many new agricultural enterprises have opened up in the past 15 years, and the population has increased by almost 40 …
Farmers' Estimations Of Sheep Weights To Calculate Drench Dose, R B. Besier, Diane Hopkins
Farmers' Estimations Of Sheep Weights To Calculate Drench Dose, R B. Besier, Diane Hopkins
Journal of the Department of Agriculture, Western Australia, Series 4
Undersosing with drenches is a mojor cause of anthelmintic (drench) resistance in worm parasites of sheep.
When farmers use a drench at less than the recommended dose rate, some worms may survive, and their ability to resist treatment with the chemical involved is passed to their offspring. Over a period of time, matings between worms with different degrees of resistance can produce individuals able to resist the drench at the recommended dose rate or even higher.
Farmers must use adequate dose rates so that worms do not have a chance to survive treatment.

Evaluation Of The Crack Approach For The Control Of Drench Resistance In Sheep Worms, J R. Edwards, Helen Chapman, Jon Dunsmore
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture launched the CRACK approach to worm control in September 1985 in response to finding that anthelmintic (drench) resistant worms were present on 68 per cent of a random selection of Western Australian sheep farms.
The high cost of internal parasites in terms of lost production and drench costs, together with the high prevalence of resistant worms of farms, confirmed that changes were needed to existing parasite control measures in sheep.l

Rangeland Surveys : A Basis For Improved Land Use, P J. Curry, Alan Payne
Journal of the Department of Agriculture, Western Australia, Series 4
In mis 1988, the Department of Agriculture started a three-year programme to assist pastoralists in the Murchison River catchment to update land management planning of their stations. This Project, which is funded by the National Soil Conservation Program, will use interim results from a recent rangeland survey which has investigated and mapped the grazing recources throughout the region.
Elsewhere in Western Australia's pastoral areas, information on the productive potential of each area - and the management problems inherent for each class of land - are being used to help pastoral managers of Soil Conservation Districts rehabilitate degraded areas. This information …
