The Accumulation And Run-Down Of Dieldrin In Wethers Grazed On Paddocks Previously Treated With Dieldrin, Tony Albertsen, Roy Casey, Keith Croker

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

In mid 1987, the organochlorines (O/Cs) DDT, dieldrin, heptachlor and chlordane were deregistered for agricultural and horticultural use in Australia. These chemicals had been used widely, and land on several hundred Western Australian farms, particularly where potatoes had been grown, was contaminated with chemical residues. Livestock grazing pastures on such land was also contaminated, and our beef exports were threatened. In 1988, the Western Australian Department of Agriculture started a two-year project to collect information from sheep which were grazed on land that had previously been treated with O/Cs, particularly dieldrin. The levels of O/Cs in body and wool fats …

Progress In Mastitis Control : A Simple Control Programme That Works, G R. Olney, R. K. Mitchell

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

Farmern receive regular advice on their herd mastitis levels, and advice is available on overcoming specific problems.

Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill

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

Although long known as a potential toxic species because of its content, and although it is widely distribuited in all Australian States, cotton fireweed has not generally been consdidered toxic because it is unpalatable and not usually eaten by stock.

In 1973 cattle deaths occured near Ravensthorpe which led to research into Senecio quadridentatus (cotton fireweed).

The plant must be seen as a potential toxic species in situations where the lack of other feed forces cattle to eat the normally unpalatable cotton fireweed.

Rabbit Increase : A Warning, A R. Tomlinson

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

THE increase in rabbits which has become apparent in many parts of our agricultural areas is a warning to those who considered the problem solved by myxomatosis that these pests are still present and are quite capable of building up to a major menace again, unless they are continually and effectively controlled.

Poultry : Toxic Factors In Protein Supplements, D F. Hessels

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

The toxic effect of low quality and/or stale protein supplements can be a problem in the poultry industry.

This article describes trials carried out to assess their importance in Western Australia.

Rabbit Fumigation, C D. Gooding

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

Not all poisons act by absorption from the alimentary tract or through the skin, the fumigants are a big group of poisons used in pest control which act on the animal after being absorbed through the lungs.

FUMIGATION as it is now used in Western Australia is not always an economical way of treating whole farm properties. It should only be used on its own in areas where it is impossible to use other more permanent methods such as warren destruction.

List Of Registered Stock Foods : 1963-64, H G. Cariss

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

All foods for stock sold in Western Australia are required by the Feeding Stuffs Act, 1928-1951, to be registered annually with the Department of Agriculture.

Anticoagulants For The Control Of Rats And Mice, C D. Gooding

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

LATELY there have been many requests for information on suitable poisons to use in baiting rats and mice.

Most enquirers have stated that they "tried a certain brand of bait" and found that the rats only "ate it up and kept coming back for more."

This article on Warfarin—as a rat and mouse poison—is presented to clear up some of the problems of rodent poisoning.

Marker Dyes In Antibiotics, K Needham, N. Ingleton

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

'For some years the presence of penicillin in milk has been a serious problem for the dairy industry.

When cows are treated for mastitis with antibiotics some residue finds its way into the milk.

Unless the milk from treated cows is withheld for at least 72 hours after treatment this residue enters the bulk milk supply.

Vermin Control Research In Western Australia 1952-1962, C D. Gooding

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

C. D. Gooding, B.Sc. (Agric), reviews the first 10 years of vermin control research work in Western Australia.

Pickled Wheat Is Safe For Sheep : Feeding Trial, J Craig, H. P. Dwyer

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

FARMERS are often left with a surplus of pickled grain from seed wheat supplies. Many would like to feed this to their stock, but do not do so because they think there may be a risk of poisoning.

This trial was designed to investigate the effects of feeding such grain to sheep.

Chemical Poisoning In Animals. 1. Arsenic, H D. Seddon

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

ARSENIC is poisonous to all animals and to man in quite small amounts and exposure to poisoning is often a result of human carelessness.

It is present in many chemical dips used for control of insect parasites on stock, and in agricultural fruit sprays and weed killers whose relative cheapness makes their use economical.

However, their potential danger and the economic loss they may cause are a disadvantage.

Dingo And Fox Baits, Department Of Agriculture, Western Australia

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

THE Vermin Control Section of the Agriculture Protection Board has devised an effective method of preparing poison for impregnating dingo and fox baits. The method is recommended where it is not convenient to use commercial 1/2 grain strychnine tablets.

Control Of The Emu, C D. Gooding, J. L. Long

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

Vermin research officers C. D. GOODING and J. L LONG give the latest recommendations for control of the emu, based on a series of observations and poisoning experiments in the northern wheatbelt.

Drugs For Worm Control. 1. Sheep Drenching Trials With Mk 360, M R. Gardiner, J. Craig

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

DRENCHING sheep with drugs designed to eliminate parasites has become an established practice in the higher rainfall districts of Western Australia.

has been tested in many trials, and their is little doubt that drenching sheep clinically affected with worms—the so-called "tactical" drench—is valuable and necessary.

However, there is usually less general acceptance of the value of "strategic" drenching— the prevention of clinical parasitism by giving the drug at certain specific times, pre-determined by a knowledge of the numerical rise and fall of the various parasites within the animal body.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

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

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

A Grazing Management Trial For The Control Of Lupinosis In Sheep, H G. Neil, C. M. Ralph, A. W. Hogstrom

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

A "WASTING" disease of sheep grazing on lupin stands, usually accompanied by heavy mortality, has become a serious problem in coastal areas between Perth and Geraldton in the past ten years.

An Improved Method Of Utilising Strychine In The Preparation Of Dingo And Fox Baits, L A. Harrison

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

AT present dingo and fox baits are made from fat or other material attractive to the animal to be poisoned, into which is inserted either alkaloid or soluble strychnine.

Lupinosis, H W. Bennetts

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

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern.

The Success Of The Rabbit 'Killer' Trials, A R. Tomlinson

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

SUCCESS well beyond what was anticipated has been achieved in a two year trial of a modified version of the rabbit "killer" method.

In the "killer" method, trained officers are employed to kill rabbits instead of to inspect and supervise the activities of farmers and, in fact, these officers do all the actual work of destruction.

This system was advocated by the W.A. Royal Commission which reported on Vermin Control in this State in 1944, and it was used successfully in New Zealand.

These trials were applied only to poisoning and not to overall destruction measures. The main object was …

Galah Poisoning : Kill The "Cocky", John L. Long, F. Vagg

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

NO! Not the one that tills the land, but his enemy, the pink and grey galah (Kakatoe rosei-capilla).

Farmers have usually found the destruction of galahs damaging standing crops and bagged, or stored grain, fairly difficult.

Past methods of boiling grain and adding sweetened substances are rather laborious and require a lot of time.

Now, a quick and relatively simple method is available to farmers, using paraffin oil to adhere poison to the grain.

Wild Dog Control In The North-West, R J. Fraser

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

BECAUSE of its sparsely-settled condition, the North-West of Western Australia is almost an ideal breeding-ground and hunting-ground for wild dogs.

Even the best of the pastoral country is but thinly populated and there are large areas of rugged country which is seldom traversed by white men.

Hit Rabbits This Winter : It Will Check Breeding And Give More Valuable Feed For Summer Grazing, C Marshall

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

NOW that the current summer "1080" Rabbit Drive is drawing to a close, it is time we considered our future plans.

I am afraid that in the past most farmers have relied far too much on summer control as the complete answer to rabbit destruction and that this reliance has increased considerably following the introduction of "1080" poison, plus the valuable assistance received from the myxomatosis virus.

Feeding Pickled Wheat To Pigs, Department Of Agriculture, Western Australia

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

INQUIRIES are frequently received from farmers asking whether it is safe to feed pickled wheat to pigs, and if so, the quantities which would be suggested.

Until very recently there was no experimental information on the safety or possible dangers of these wheat pickling agents, but feeding trials completed last year at the Animal Health and Nutrition Laboratory, Nedlands, have provided some of the answers to these questions.

Vermin Control In W.A, A R. Tomlinson

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

THE annual report of the Agriculture Protection Board of W.A. for 1958-1959 indicated that while vermin control had continued at a relatively high standard throughout the State, most of the animal and bird pests were at the lowest level within the memory of most people.

However, there were ample warnings that any relaxation in control work could have rapid and serious consequences.

There Is No Mystery About 1080, A R. Tomlinson

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

DESPITE the widespread publicity given to sodium fluoroacetate or "1080" and its general use throughout agricultural areas, there appear to be many misconceptions regarding the poison itself, its control, dangers and precautions and also the method of application. I will mention several of the questions often asked and give the answers.

Zamia Palm Poisoning, F C. Wilkinson

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

THE Zamia palm (Macrozamia Reidlei) is a common plant in the jarrah and karri forest country and on the coastal plains and is one of the earliest recorded Australian poison plants.
