Eradicating Footrot From Western Australia - A Farmer's Guide, Department Of Agriculture, Western Australia

Agriculture reports

Virulent footrot can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep take a greater risk, but even properties with a closed breeding flock are at risk from stray sheep. People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs. Footrot can strike anywhere and often without warning. It is important to remember that once it is found; getting to know and understand the disease will help you to beat it. A …

Bulletin 4394 - Exotic Diseases - Sheep And Goats, Agriculture Western Australia

Bulletins 4000 -

An exotic disease is a disease which does not occur in Australia.

If an exotic disease did occur in Australia it would cause production losses, stock deaths and stop exports of primary production. When export markets are lost they can only be re-established once it is proven the disease is eradicated. Some exotic diseases may be transmitted to humans

Virulent Footrot : Mild Or Severe?, Laurie Depiazzi

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

The footrot eradication scheme in Western Australia has resulted in a low prevalence of severe footrot.

To appreciate the achievement, we need to understand what exactly is being eradicated. 'S' strains of Dichelorbacter nodosus, the infectious bacterium of footrot, are the target of footrot eradication. Laurie Depiazzi examines the basis for eradicating 'S' strains.

Quality Wool Production At Lower Cost, Peter Metcalfe

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

Low wool prices are forcing farmers to reduce their sheep management costs but, fortunately, cost cutting is not resulting in lower wool production, poorer wool quality or lessened sheep care on the best wool growing properties.

Miscellaneous Publication No 33/93 - Virulent Footrot A Farmer's Guide To Eradication, Department Of Agriculture, Western Australia

Animal production and livestock published reports

The first thing to understand about virulent footrot is that it can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep have a greater risk, but even closed breeding flock properties are at risk from stray sheep.

People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs.

Footrot can strike anywhere and often without warning.

The important thing to remember is that once it is found, getting to know and understand the …

Do Farmers Really Want To Eradicate Sheep Lice?, Chris Hawkins

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

With the termination of Western Australia's Sheep Lice Eradication Campaign in 1993 farmers' views about the eradication of sheep lice are of greater relevance now than in the past. Lice control now rests with individual farmers and continuing local lice cell groups .

A recent survey of producers in the Moora Shire provides some key insights into farmers' thoughts about sheep lice and their eradication.

Progress Toward Eradication Of Virulent Footrot, Bob Mitchell

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

Western Australia is well placed to eradicate virulent footrot from the State's sheep and goat populations.

Between 1950 and 1993 the proportion of sheep flocks with footrot fell from about 15 per cent to less than 2 percent, and the 1990-92 outbreak has been turned around. One hundred and eighty properties (]. 7 per cent) of flocks, mostly in the high rainfall South-West, are in quarantine for footrot today.

This high level of footrot control is the result of strong support from the sheep industry and years of good cooperation between farmers and the Department of Agriculture.

Choosing Shower Dips For Sheep Lice, Tony Higgs, Bob Love

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

The performance of all shower dip chemicals for sheep lice can vary depending on the active chemical and the conditions under which they are used.

Department of Agriculture trials have indicated that the wettable powders coumaphos and magnesium fluorosilicate were less effective at eradicating sheep lice than were synthetic pyrethroid and organophosphate dipping chemicals.

However, failure to eradicate sheep lice may be the result of several factors, many of them related to management.

New Technique Joins The Fight Against Footrot, Laurie Depiazzi, Mike Palmer, David Pitman

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

The diagnosis of footrot in sheep and goats is not an easy task. Two main techniques are used for diagnosis - inspection of diseased feet on a farm and laboratory testing of bacteria isolated from foot scrapings. The interpretation of the results obtained by these methods requires a good understanding of the various forms of footrot.

A new laboratory technique has halved the time taken to detect those strains of the bacterium, Bacteroides (Dichelobacter) nodosus, that cause each form of the disease.

Atrophic Rhinitis In Pigs, A R. Mercy

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

Severe atrophic rhinitis in pigs recurred recently in Australia after an apparent absence of some 20 years. The first of these recent cases occurred in a Westerm Australian herd in late 1984 and since then six other local herds have reported the disease. Severe atrophic rhinitis has also been seen recently in South Australia.

Atrophic rhinitis is a complex disease which causes degeneration of the nasal cavity, twisting of the snout and sometimes occasional bleeding from the nose.

It occurs only in pigs and severely affected animals may have a slower growth rate.

Dispelling Some Myths About 'Dermo', J R. Edwards

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

There are a lot of misconceptions and myths about dermatophilosis, a disease which can kill young lambs, affect wool quality, make shearing difficult and make sheep susceptible to fly strike.

One misconception is perpetuated by the incorrect use of the name mycotic dermatitis, which implies that a fungus causes the disease. This is not so.

The disease is caused by the bacteria Dermatophilus congolensis, which attacks the sheep's skin and eventually forms a lesion or scab in the wool, and so is better called dermatophilosis, 'dermo' or 'lumpy wool'.

Veterinary Epidemiologist at the Albany Regional Office, J.R. Edwards, discusses …

The Sheep Measles Control Programme, J B. White

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

In the first seven months of 1968 Australia exported to the United States 17 747 tons of boned mutton; of this 2 198 tons, or 12.4 per cent, was condemned on arrival in that country.

The main cause of rejection was the presence of Cystkercus ovis cysts, the intermediate stage of the tapeworm Taenia ovis, of which the definitive host is the dog.

In 1969 the Western Australian Department of Agriculture decided to study the epidemiology of this disease.

This was the beginning of the work which would evolve into the 'Three Shire Control Programme'

Mycotic Dermatitis (Lumpy Wool) Of Sheep, M R. Gardiner

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

MYCOTIC dermatitis is a common disease of the skin and overlying wool of sheep (and other herbivorous animals).

The photographs show the typical crusts and scabs which result from infection of skin, hair and wool follicles by the mycotic dematitis organism.

This article reviews the causes of lumpy wool infection and sets out control measures.

Two Causes Of Reduced Profit From Pigs, G A L Ward

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

LOSS of condition in a pig affects profits more severely than slow rate of growth.

Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain.

Black-Leg In Cattle, F C. Wilkinson

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

BLACK-LEG is still a serious disease of cattle in the South West coastal region, causing deaths in young cattle.

The disease is characterised by hot swollen muscles, acute lameness and rapid death.

Cattle affected are usually 6 to 12 months old, in fat condition, and grazing on lush pastures.

Are Bactericides Necessary In Sheep Dips?, M R. Gardiner

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

THE OCCURRANCE of mycotic dermatitis in sheep in Western Australia, although rather unpredictable, is quite frequent throughout the higher rainfall districts.

Efforts have been made for several years to control infection by adding bactericides to dips.

Swine Fever And African Swine Fever, V W. Smith

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

PIGS may become infected by viruses which also cause disease in other animals (for instance foot-and-mouth disease) but there are two virus diseases worthy of special mention because they cause clinical disease in pigs only.

Bovine Tuberculosis Control In Western Australia : Past, Present And Future, M R. Gardiner

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

TWENTY YEARS AGO, tuberculosis was a widespread and serious disease in the dairy cattle of Western Australia.

Besides having a marked depressing effect on the economy of the dairying industry, bovine tuberculosis was a constant hazard to humans coming in contact with it.

This Could Happen Here : If Foot-And-Mouth Disease Came To Western Australia, Department Of Agriculture, Western Australia

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

THE first outbreak would probably be on a piggery not far from a major port. But it might also appear among cattle or sheep in a similar area, or even on a cattle station in the North.
