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

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.

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.

Mastitis In Western Australian Dairy Cattle, Department Of Agriculture, Western Australia

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

IN 1964/65, as a first step towards a State-wide mastitis control programme, the Department of Agriculture undertook a survey of mastitis in West Australian dairy herds.

The survey was designed to obtain a clear picture of the incidence and severity of the disease and is the most comprehensive mastitis survey carried out in Australia.

Bluetongue Of Sheep, M R. Gardiner

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

BLUETONGUE is a serious disease of sheep, mainly of introduced European breeds, throughout the African continent.

It is maintained there by wild and domestic ruminants in the presence of certain insect vectors (carriers).

The disease has probably existed there from immemorial times among the indigenous ruminants, emerging as a recognised disease only when the much more susceptible European breeds were brought into the continent.

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver

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

IN the December, 1967, issue of the Journal of Agriculture, we reported on five development budgets for the Esperance region.

The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.

West Midlands Development : Poison Plants In The West Midlands, T E H Aplin

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

TOXIC plants have caused considerable economic loss to stock raisers since the early days of settlement in Western Australia.

Although much is now known of the toxic materials contained in such plants, and although most of the plants have been thoroughly publicised, losses are still occurring in many areas.

Amsinckia Or Yellow Burr-Weed (Amsinckia Spp.), G R W Meadly

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

YELLOW BURR-WEED is widely established in the Wimmera and Mallee districts in Victoria, presumably introduced with fodder brought to this country from the United States about 1914.

It is a problem in Oregon and other north west wheat areas of America.

The weed is also widespread in New South Wales, being most troublesome in the wheat-growing sections of the Riverina. It is not established to the same extent in South Australia and Queensland.

The recent discovery of areas infested with yellow burr-weed at Merredin prompted the Agriculture Protection Board to declare it a primary noxious weed for Western Australia.
