Journal of the Department of Agriculture, Western Australia, Series 4
Sheep worms which are resistant to chemical drenches have been detected with increasing freuency is Western Australia's south-western farming areas between 977 and 1980. These worms have anthelmintic resistance and such genetis resistance puts essential internal parasite control practices at risk.
This prompted veterinarians in the Esperance, Albany, Bunbury, Geraldton and Northam areas to survey farms to determine the prevalence of resistance to drenches and to define those sheep management practices which encourage its development.
This article describes the survey which was conducted to assess the extent of drench resistance, what causes its build-up and how it can be controlled …

The Economic Potential Of Cashmere Production, A T. Kelly
Journal of the Department of Agriculture, Western Australia, Series 4
Although the cashmere industry has developed rapidly in eastern Australia, development in Western Australia has lagged behind because of local restrictions on the use of feral goats. However, recently the Agricultural Protection Board has eased these restrictions.
In Western Australia there are about 30 to 40 producers with commercial cashmere flocks, involving a total of 7,500 to 10,000 goeats. In most agricultural areas where sheep production occurs, cashmere production is also possible.
In the following article, A. T. Kelly, an adviser with the Marketing and Economics Branch, discusses the economic potential of cashmere production in this State and compares …
