Drench Resistence : A Large Economic Cost, Brown Besier, Jill Lyon, Norm Mcquade
Drench Resistence : A Large Economic Cost, Brown Besier, Jill Lyon, Norm Mcquade
Journal of the Department of Agriculture, Western Australia, Series 4
Drench restistant worms can cost sheep farmers a lot of money - more than most probably think. Brown Besier, Jill Lyon and Norm McQade discuss some new research that shows the value of conducting routine drench tests to ensure effective worm control.
Sustainable Worm Control In Sheep, Robert Wroth
Sustainable Worm Control In Sheep, Robert Wroth
Journal of the Department of Agriculture, Western Australia, Series 4
Deciding on the best worm control program for your farm can be a complex matter, but guidelines in this article by Robert Wroth should make it simpler.
Breeding Sheep For Worm Resistance, John Karlsson, Johan Greeff, Julia Harris
Breeding Sheep For Worm Resistance, John Karlsson, Johan Greeff, Julia Harris
Journal of the Department of Agriculture, Western Australia, Series 4
Sheep production os one of Western Australia's most important agricultural industries. However, it is faced with the serious threat of sheep worm populations becoming increasingly resistant to the available drenches.
Although it's not a 'quick fix' solution, part of the long term answer may be selection for sheep with greater resistance to worms.
The Sheep Lice Detection Test, Peter Morcombe
The Sheep Lice Detection Test, Peter Morcombe
Journal of the Department of Agriculture, Western Australia, Series 4
Sheep farmers would agree it is difficult to find sheep lice when carrying out an inspection.
The lice detection test makes this task easier and helps farmers decide how to control lice. The test also helps community liaison groups with eradication of lice infestations in specific areas, and provides data for epidemiologists to monitor changes in prevalence of lice and efficacy of treatments. Tests are much cheaper than flock inspection on the farm.
The present lice detection test was developed by the Australian Wool Testing Authority (A WTA) and introduced as an integral part of the Western Australian Sheep Lice …
Understanding The Importance Of Eperythrozoon Ovis Infection In Sheep, Marc Kabay
Understanding The Importance Of Eperythrozoon Ovis Infection In Sheep, Marc Kabay
Journal of the Department of Agriculture, Western Australia, Series 4
Assigning priorities for research on sheep diseases relies in part on understanding the prevalence and economic impact of each disease.
Eperythrozoon ovis infection in sheep, for example is a common, but not costly, disease.
Summer Drenching Of Sheep : New Recommendations For High Rainfall Areas, Brown Besier, Jill Lyon
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 …
New Policy Hits Hard At Sheep Lice, F C. Wilkinson
New Policy Hits Hard At Sheep Lice, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
In March 1977 the regulation requiring compulsory routine dipping of all sheep within 30 days of shearing changed, and only infested flocks were required to be dipped. This change has allowed concentrated eradication efforts.
Hydatid Disease In Western Australia, G C De Chaneet
Hydatid Disease In Western Australia, G C De Chaneet
Journal of the Department of Agriculture, Western Australia, Series 4
BECAUSE hydatid disease is a disease of humans as well as animals, every dog owner should be aware of the conditions that perpetuate hydatids and the methods of control.
The incidence of hydatids in Western Australia in the past has not been high.
However, the increase in sheep numbers over recent years, together with the intensification of farming methods, may lead to a rise in incidence unless stock owners, particularly sheep farmers, take steps to control the disease.
Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson
Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
Indications from a continuing sheep trial at Margaret River are that farmers in high rainfall areas could increase stocking rates and lamb growth rates by lambing in September- October rather than July-August.
The results also indicate that farmers in the area may be spending more than necessary on worm control.
Lupinosis In Sheep. 1. Laboratory Studies, M R. Gardiner, M. C. Nottle
Lupinosis In Sheep. 1. Laboratory Studies, M R. Gardiner, M. C. Nottle
Journal of the Department of Agriculture, Western Australia, Series 4
IN earlier articles by Bennetts (1957, 1960), the clinical and pathological features of lupinosis, as seen in field outbreaks, were described.
The suggestion was made that the roughage portion of the lupin plants was responsible for the disease.
More recent observations suggest a relationship between parasitism and lupinosis.
