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.

Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.

Improving Potato Seed, James P. Fallon

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

SOME of the oldest records of potato cultivation show that throughout the ages it has been generally accepted that periodically, a change of seed is essential, and the only means of maintaining satisfactory yields in crops.

Even today most potato growers are familiar with the term "run out" as applied to any particular line of potatoes which tends to progressively decrease in vigour and productivity when planted from year to year.

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.

Bacterial Blight Or Black Spot Of Walnuts, O M. Goss, R. F. Doepel

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

Bacterial blight is the most important disease of walnuts in Western Australia.

In bad seasons it can cause heavy losses in susceptible varieties such as Wilson's Wonder, and in some seedling trees.

Carefully timed sprays greatly reduce the incidence of bacterial blight, and it is also recommended that less susceptible varieties—such as Franquette— should be used for new plantings.

Plant Diseases In Western Australia, S C. Chambers

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

This first supplement contains the diseases recorded on vegetables, cereals, grasses and pasture legumes, in the period between the publication of the revised lists (1), (2) for these hosts, and June 30, 1961

Spread Super For Cereal Crops, T E. Mcdowell, J. A. C. Smith, W. J. Toms, M. D. Carroll

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

THE use of bulk superphosphate broadcast direct on to the paddocks is a new method of reducing fertiliser costs.

But it has long been known that broadcasting phosphate is less efficient than drilling it in with the seed.

The experiment reported here was designed to demonstrate this point.

Vibrionic Dysentery Of Pigs, M R. Gardiner

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

VIBRIONIC DYSENTERY of pigs, also known as porcine vibriosis and swine dysentery, has been recognised for many years in the U.S.A. It was first reported in Australia in 1938, in South Australia, and later in both Victoria and New South Wales.

This brief description of a disease recently diagnosed for the first time in Western Australia is given so that breeders have some chance of recognising it in their herds. Suspected cases should be reported without delay.

Antibiotic Residues In Milk : The Farmer's Responsibility, N Ingleton

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

THE LEVEL of antibiotic residues in commercial milk supplies has been steadily increasing over the past few years.

These residues find their way into the bulk milk as a result of milk from cows under antibiotic treatment for mastitis or other infections being included in the bulk milk for sale.

Toxic Annuals In Horticulture, Robert Dunlop Royce

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

THE number of poisonous shrubs and trees that are grown in gardens is very great, and several of these species have been discussed in detail.

It is probable that few people realise just how many of the commonest garden plants are in some way or under some circumstances, likely to contain a toxic principle.

Furthermore, this is not confined to the longer lived plants, but it applies equally to the annual plants, both summer growing and winter growing.

Wheat Quality, Department Of Agriculture, Western Australia

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

IN August, 1956, the Australian Agricultural Council agreed that, as a first step in the further examination of all aspects of the subject of wheat quality in Australia, a conference of all interested parties should be convened by the Department of Primary Industry.

Stocking Rate And Pasture Management, B F. Carlin

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

FARMERS west of the Great Southern Railway, raising sheep and beef cattle, frequently associate soil deficiencies with difficulties in holding sub. clover in their pastures.

Field observations and some trials in those districts indicate that in many paddocks the problem arises through undergrazing rather than a deficiency in the soil.

Wheat Variety Trials On Research Stations, J T. Reeves, J. L. Mcmullan

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

THE results of wheat variety trials at seven Research Stations in the medium and low rainfall areas for the years 1957, 1958 and 1959 are presented and discussed.

The trials are designed to give information on yield and flour quality of promising crossbreds originating from local breeding programmes and newly produced varieties from other parts of Australia.

Large scale variety trials are the final tests in the long process of selection and testing which is essential before a new crossbred can be released.

The new wheats are compared with standard ones under different conditions of soil and climate.

Mosaic Disease Of Cucumbers : A New Resistant Variety, H L. Harvey

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

TESTS with the cucumber variety Ohio MR 200 which was introduced from the U.S.A. (1), have shown it to be almost unaffected by the cucumber mosaic virus. It is a good type and satisfactory yielder and promises to be the answer to the cucumber mosaic problem in Western Australia.

Bulletin No 3410 - Design Of Dairy Premises, A. L. Hamilton, F. J. Fielder

Bulletins - 3000 - 3999

CONDITIONS in the dairy industry are changing rapidly.

There is a trend towards larger and more convenient milking sheds. Farmers have accepted that economic production is possible only with relatively large herds; they are thinking bigger than before. The aim is for herds of 100 or more, instead of the earlier objective of 40 to 50 cows.

To enable herds of this size to be milked quickly, premises must be designed for convenience and to enable cows to be handled without unnecessary movement on the part of the operators.

Also of the greatest importance is the need for the design …

Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms

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

ON newly-cleared land at Esperance Plain Research Station the use of sulphate of ammonia on cereals has proved profitable over a number of seasons.

The response to sulphate of ammonia varies markedly with the season.

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

Diseases Recorded On Cereals, Grasses And Pasture Legumes In Western Australia, S C. Chambers

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

This list constitutes a revision of portion of the census published by Came (1925) and supplemented by the same author in 1927.

It also contains records of diseases identified in the period between these earlier publications and December 31, 1959.

The list is divided into two sections, the first dealing with pasture legumes and the second with cereals and grasses.

The sections are arranged alphabetically according to the botanical names of the host plants. In general, the viral, bacterial, fungal and nematodal diseases and physiological disorders are listed in that order.

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.

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 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.
