Enzymatic Sulfurylation Mechanisms, Irving Hyman Goldberg

Student Theses and Dissertations

Sulfate activation and transfer to lipids, polysaccharides, and aminoalkyl phenols have been studied In a variety of biological systems. The transfer of S³⁵O₄ from radioactive 3'-phosphoadenoslne 5'-phosphosulfate (PAPS³⁵) into lipid-soluble material has been investigated in cell-free preparations of rat brain and liver. In brain of 10-20 day old rats activity was found in the particulate fraction of the homogenate, whereas in young adult rat liver activity resided in the supernatant fraction (105,000 x g). In both systems incorporation was stimulated by the addition of a crude mixture of the isomers of N-acetyl sphingosine. Evidence accumulated …

The Biology Of A Colonial Hydroid, Chandler Montgomery Fulton

Student Theses and Dissertations

Simple invertebrate metazoa offer many potentialities for study of growth and differentiation - potentialities which have not been realized because the organisms usually have been difficult to handle in the laboratory. A simple coelenterate, the brackish-water colonial hydroid Cordylophora lacustris, was selected for the present work, and was domesticated so that it could be grown and manipulated under controlled laboratory conditions. Methods have been developed permitting exponential increase in hydranth number with a doubling time of about three days. Five ions — Na⁺, K⁺, Ca⁺⁺, Mg⁺⁺, Cl^- — have been found …

Pinkeye In Sheep : Some Timely Comments, F C. Wilkinson

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

DURING the summer months, it is almost inevitable that numbers of sheep in Western Australia will suffer from contagious ophthalmia—or pinkeye, to give the disease its more popular name.

As it can be quite a distressing disease which can cause severe setbacks, most flock owners, knowing that medicaments are available for the treatment of pinkeye, will feel that they should do something for the affected animals.

Insect Pests : Aphides, Clee Francis Howard Jenkins

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

THE members of the aphis family are remarkable creatures both in structure and habits.

They are practically world-wide in their distribution and despite their small size and apparent fragility they thrive under a wide variety of conditions and are among the most prolific breeders in the animal kingdom

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.

Record Keeping On Dairy Farms, R A. Bettenay

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

FARMING today is very much a business venture and the successful farmer is the one who is not only capable of doing the manual work, but who also has the ability to plan the work routine and determine which of the possible avenues is likely to bring the greatest financial return.

For this, and many other reasons, simple but adequate records must be kept by all dairy farmers.

Many types of records should be kept but if a routine is followed, a few moments' work each evening will suffice to keep things up to date.

Registered Stock Foods 1960-61 : Supplementary List, Department Of Agriculture, Western Australia

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

A supplement to the list of Registered Stock Feeds available in West Australia.

Foster-Mothering Of Calves, Maurice C. Cullity, K. W. Simes

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

"SAVE those calves" is a slogan which has been used frequently in propaganda to reduce the slaughter of heifers when it is thought that the supply of replacement animals to our dairy herds might be unduly low.

Although there is no fear of this at present, the wastage of calves both heifers and bulls, in Western Australia is unduly large.

How Much Food Should I Give My Dog?, F C. Wilkinson

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

THIS is a question which every veterinary surgeon has heard hundreds of times, and one that it is impossible to answer in general terms because dogs differ so much in their food requirements and because the nutrient values of various foodstuffs vary considerably.

The Problem Of Low Solids-Not-Fat In Milk, Laurence C. Snook

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

TO the consumer of milk, the solids-not-fat fractions is of prime importance.

This contains the protein, the minerals and the milk-sugar which collectively make milk such a valuable and palatable food.

If we wish to encourage increased consumption of milk as a health food it is essential that quality must be maintained and if possible improved.

Producers and distributors must always remember that if maximum sales are to be obtained, the needs of the consumer must remain paramount.

The Care Of The Breeding Sow, P C. Beck

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

PIG-RAISING is a specialised field of animal production, which, to be profitable must incorporate both a scientific and a practical approach.

These two factors must be complementary, for without a sound practical approach, the value of the scientific principles involved, e.g., in breeding and compounding rations would accordingly be reduced.

Teaser (Vasectomised) Rams : A Management Advantage, W L. Mcgarry, I. K. Stott

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

WITH normal late spring-early summer matings (October-December) teaser rams, correctly used, will give a more concentrated lambing.

This has been shown under Western Australian conditions in trials conducted at the Wongan Hills Research Station.

In one experiment a group of 100 ewes which had one per cent, of teasers for 14 days before the fertile rams went in, dropped 42 lambs in the first two weeks of lambing, compared with 17 lambs from 100 ewes that were not teased.

The use of teasers in all Research Station flocks is now routine practice.

Rabbit Control In 1960, C Marshall

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

IN the year 1859, an enthusiastic sportsman in Victoria took delivery from the clipper "Lightning" of a small consignment of wild European rabbits which he joyfully released on his estate at Barwon Park, near Geelong, in order to assure himself of some rough shooting.

He was not the only rabbit importer on record—tame rabbits were brought into Australia before and after 1895 and doubtless there were other importations of the wild rabbit—but he is generally credited—or discredited—with having triggered off the rabbit plague.

Weed Research. 8. Weed Control In The Vineyard, Geoffrey A. Pearce, W. R. Jamieson

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

WEED control in the vineyard has been achieved by cultivation for many centuries and it is only during recent years that attention has been given to the use of herbicides for this purpose.

Today there is little risk to the vine in using any one of the herbicides listed in this article, and in general the main considerations governing the use of chemicals for weed control are the cost of the operation and the effect which it is desired to achieve.

Brucellosis Can Cause Contagious Abortion In Cattle And Undulant Fever In Man, F C. Wilkinson

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

WHEN the cow, shown in the accompanying photograph, was purchased it had a small fluid-filled lump on the left knee.

The swelling did not appear to be painful but gradually increased in size until it assumed the proportions shown in the picture.

It was a typical case of "big-knee," one of the less common manifestations of Brucellosis—the disease commonly known as contagious abortion—and a blood test of the animal confirmed the diagnosis.

Diseases Of Goats, J Shilkin

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

MANY of the diseases of goats are common to sheep and cattle, and, as in these species, correct feeding, hygiene and general care and management will assist in the avoidance of serious ailments.

In this article an attempt will be made to advise goat-owners on the diagnosis of the more common ailments, and suggestions as to treatment will be offered where possible.

It should be appreciated however that where veterinary assistance is obtainable it is preferable to first-aid treatment. A qualified veterinarian has access to newer and more efficient methods of treatment than are available to the layman.

Drought Feeding Of Sheep, Laurence C. Snook

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

WHEN this talk on drought feeding of sheep was suggested conditions were very serious over large tracts of pastoral country.

Many stations had not received a worthwhile rain for over 12 months and it appeared that grazing animals would have to be fed if they were to survive.

Requests have been received for advice on the cheapest way to keep sheep alive. Drought feeding in any form is a gamble. There is always the risk that the stock will eventually die despite the consumption of much costly feed.

It follows that if an effort is to be made to save …

Bracken Poisoning In Cattle, P B. Lewis

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

THE ingestion of bracken fern causes the death of numbers of young cattle in the South-West of Western Australia every year.

Early experimental work in the United Kingdom demonstrated that bracken contained an anti-Vitamin Bl factor called thiaminase which was thought to be the cause of the poisoning, but later work indicated that a bone marrow poisoning, not yet chemically identified, was responsible.

Second West Australian Random Sample Egg Laying Tests : 1958-59, R H. Morris

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

4S part of the poultry improvement plan for Western Australia, the Department of Agriculture inaugurated a random sample laying test for commercial grade chickens at the Poultry Research Station, Herdsman Lake, in 1957.

Simnel Cake, H M. Gloster

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

THIS is a traditional cake of English rural origin that is usually served on "Mothering Sunday" or Mid-Lent Sunday (the fourth Sunday in Lent).

Mothering Sunday is the day on which sons and daughters visit their parents and take them gifts. Quite often the gift takes the form of a Simnel cake.

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.

Famous Sheep Breeds. 3. The Leicester, J A. Mallett

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

THE Leicester sheep, often referred to in Australia as the "English" Leicester to distinguish it from its relative, the Border Leicester, is the oldest of the improved British breeds.

Its development from the nondescript local sheep marked an advance in stockbreeding technique which did much to make Britain famous as the "stud-farm of the world."

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.

Fruit Fly, D G. Shedley

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

FRUIT fly control is compulsory! To obtain effective control of fruit fly it is necessary to combine strict orchard hygiene with bait spraying.

In addition, cover spraying with DIPTEREX will give extra protection to stone fruit and pears.

When the breeding powers of the fruit fly are considered it is easy to understand why home growers and orchardists need to fight a continual battle against this pest.

Better Rations For Broiler Production, P Smetana

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

DURING 1959, trials were conducted at the Poultry Research Station, Herdsman Lake, with the object of developing a broiler-feeding ration that was better than the one at present recommended by the Department of Agriculture and commonly used by local broiler producers.

Free Feeding For The Control Of Rabbits, C Marshall

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

IN common with most other farm work, the control of rabbits calls for a high degree of skill, patience and perseverance.

There is no short cut to success, and if results are required we must be prepared to give of our best.

Failures of control works are experienced at various times, and the reasons can generally be traced back to something we have failed to do or some short cut we have tried to take.

However, we should not lose heart from one failure. During normal farming procedure, if a farmer's crop fails he does not give up planting in …

Vibriosis, F C. Wilkinson

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

AN all-too-common problem on dairy farms is the failure of cows to conceive at times which will ensure their calves being born at the desired season—when the cows can take full advantage of the flush of green feed or, in the case of wholemilk producers, at a time when the milk is most needed to maintain their quotas.

There are of course many causes of sterility in cattle but in a survey carried out by veterinarians D. Roberts and M. Sier in 1957, it was shown that vibriosis was the main cause in 75 per cent of the herds investigated.

A Survey Of The Incidence Of Lupinosis In Sheep In The Dandaragan District In 1959, H G. Neil, W. J. Toms, C. M. Ralph

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

FOLLOWING widespread losses of sheep grazing on dry lupins, a survey of flockowners' experience with the disease was made by the Department of Agriculture in one of the districts most affected.

The idea of a survey originated from discussions with the President, Mr. K. E. Jones, and several other members of the Dandaragan Pasture Improvement Group.

The information obtained from the survey has provided a valuable factual basis for the design of laboratory and field experiments.

Lamb Marking, I K. Stott

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

LAMB marking is the most severe of the various ordeals which sheep are called upon to endure during their lifetimes—yet it is an operation, or rather a series of operations, to which the average fiockowner gives but little care and thought.
