Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Journal of the Department of Agriculture, Western Australia, Series 4
In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …

Summer Drenching Of Sheep : New Recommendations For High Rainfall Areas, Brown Besier, Jill Lyon
Journal of the Department of Agriculture, Western Australia, Series 4
'Summer drenching' has been a highly successful strategy for controlling sheep worms in Western Australia's winter rainfall regions for many years. Drenching to remove worm burdens in summer, when the risk of reinfection by worm larvae is low, is an efficient basis to year-round worm control. The Department of Agriculture recently altered its recommendations for the timing of summer drenches to take account of new findings regarding the survival of worm larvae over summer. It now recommends that sheep farmers give the first summer drench when the pasture is beginning to dry off, in spring in most locations. Experiments atMt …
New Approach To Control Of Drench-Resistant Sheep Worms On Farms, Di Hopkins
New Approach To Control Of Drench-Resistant Sheep Worms On Farms, Di Hopkins
Journal of the Department of Agriculture, Western Australia, Series 4
Worms cost the Western Australian sheep industry up to $120 million every year, and anthelmintic (drench) resistant worms account for an increasing proportion of this amount. Resistant strains of sheep worms have been found on about 95 per cent of farms tested. This alarmingly high level indicates that all farmers should have a resistance management strategy which includes having a resistance test done on their farms before they drench their sheep. However, only about 20 per cent of farmers have had a resistance test done. Farmers often believe drench resistance is not a problem on their farms, mainly because production …
