Eye Cancer In Cattle, E P. Meyer

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

THE CONDITION known as eye cancer occurs in all ages and breeds of cattle but is most common in certain strains of the Hereford breed that have non-pigmented or mottled eyes and eyelids.

A yearly incidence of up to 5 per cent can occur in susceptible herds.

Control Of Clover Infertility In Sheep, H G. Neil, H. E. Fels, C. M. Francis

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

A summary of practices recommended for the control of infertility caused by subterranean clover in West Australian sheep.

PROLONGED grazing of green subterranean clover pastures often reduces ewe fertility. In more extreme cases, obvious signs of clover disease occur.

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.

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.

Coccidiosis In Lambs On The South Coast, A J. Hadlow

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

Outbreaks of coccidiosis among autumn-born lambs on the south coast have approached epidemic proportions this year.

Similar outbreaks are likely among late winter-spring born lambs. This article describes the disease and suggests measures for prevention and treatment.

Practical Disease Prevention In The Pig Herd, R B. Richards

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

DISEASES cause loss in pig production through mortality, poor growth rate and reduced food conversion efficiency.

The cost of drugs and expert advice causes further economic loss, and the dangers to public health and to other livestock in a community are serious and often-neglected considerations.

Pig Husbandry Research In Western Australia, N W. Godfrey

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

IN the past it has not been possible to undertake research work with pigs on any appreciable scale in Western Australia.

A small herd has been maintained at Denmark Research Station for some years as a demonstration side-line unit, run in conjunction with the dairy herd.

A number of very useful trials have been carried out with the Denmark herd, but its size has limited the comprehensiveness of the type of research work that could be undertaken.

Ultrasonic Testing : An Aid To Better Breeding, B M. Goss

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

THE ultrasonic tester was originally developed as a metal flaw-detector for industrial purposes, and its usefulness for making carcass measurements on the live pig was first demonstrated about 10 years ago.

Breeding Better Pigs, B M. Goss

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

IN the past, pig breeders have tended to select animals on physical characteristics, many of which have little or no relevance to economy of production.

Selection techniques now available open up the possibility of improved pig production efficiency.

Sheep Drenching Programms, Department Of Agriculture, Western Australia

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

Drenching of sheep to prevent build-up of worm infestations is commonly practised on many properties in the agricultural districts of Western Australia. This is called strategic drenching.

Survival Feeding Of Cattle During Drought, D J. Barker, J. T. Stoate

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

TO obtain adequate returns from the grazing of developed land, which has involved considerable capital investment, farmers may carry stock at rates which, though normally satisfactory, are too high in exceptionally poor seasons.

A look at some slternatives and their costs to maintaine the herd in drought.

Deferred Grazing Improves Soft Spinifex Association, H Suijdendorp

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

THE Pastoral region in Western Australia where Triodia pungens (soft spinifex) makes up most of the vegetation, covers an area of about 17,000 square miles in the Forrest and De Grey pastoral areas.

On the deeper granitic sands in much of the region, plant associations revert to a pure stand of soft spinifex after about five or six years' grazing. It is common practice to burn at this stage, to encourage the re-establishment of other species and the production of palatable spinifex regrowth.

Introduction Of The Red-Browed Finch To Western Australia, John L. Long

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

THE Red-browed Finch (Estrilda temporalis) has been established probably since 1958 in orchard clearings in Darling Range gullies east of Perth.

Although some concern has been shown at the introduction of a new species to Western Australia, it appears to be of little economic importance.

Experiencing a drought can be likened to fighting a war.

This article looks at alternatives and costs of maintaining the flock during the drought.

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.

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.

Profitable Bacon Production In A Small Herd, B M. Goss

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

PIG HERDS are tending to become larger and more specialised, but it is still possible for the small herd of less than 20 sows to absorb by-products and spare labour very profitably.

These advantages can be lost if the scale is larger.

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.
