Hydatid Disease In Western Australia, K J. Austen
Hydatid Disease In Western Australia, K J. Austen
Journal of the Department of Agriculture, Western Australia, Series 4
BECAUSE hydatid disease is a disease of humans as well as animals every consideration must be given to its control and to the prevention of any possible increase in incidence.
The incidence of hydatids in Western Australia has not, in the past, been very high.
However, the great increase in sheep numbers which has taken place in recent years and which is expected to continue for many years to come, will produce a situation where it could be expected that the incidence of the disease will rise unless stock owners, particularly sheep owners, take appropriate steps to control the tapeworms …
Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler
Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler
Journal of the Department of Agriculture, Western Australia, Series 4
The first article in this series described the worms which commonly infest sheep in Western Australia and the symptoms caused by heavy infestations.
This article outlines the effects of seasonal changes on worm burdens in sheep.
AS a basis for planning a worm control programme it is essential to have information on the seasonal changes in worm burdens and on the factors which control these.
In this article, the more important of these are considered.

Mastitis : Modified Teat Cups Give Better Back-Flushing, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Back-flushing of the teat cups has not brought the expected reduction in the spread of mastitis in some dairy herds.
Replacement of the conventional nut-and-tail nipple with a special flushing nipple, or use of a one-piece teat cup liner, will ensure that flushing is efficient.
Control Of Lice On Poultry, B R. Vale
Control Of Lice On Poultry, B R. Vale
Journal of the Department of Agriculture, Western Australia, Series 4
DURING February and March of 1965 some particularly heavy body lice infestations were found on fowls in both deep litter and cage units in Western Australia.
In some instances comparatively new laying cage units were involved.
The most seriously affected flocks showed marked unthriftiness and depressed egg production.
Fatique In Caged Layers, P Smetana
Fatique In Caged Layers, P Smetana
Journal of the Department of Agriculture, Western Australia, Series 4
Pullets found immobilised on the floors of their laying cages may only be suffering from the easily-treated "cage layer fatigue" and should be checked for this before being disposed of as affected with the incurable fowl paralysis.

Sarcoptic Mange Of Pigs, H D. Seddon, F. C. Wilkinson
Sarcoptic Mange Of Pigs, H D. Seddon, F. C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
THIS parasitic disease appears to be much more common than is usually recognised; for, while severe cases with chronic skin lesions are readily seen, light infestations, especially on coloured pigs often go unnoticed.
When it is realised that even lightly infested pigs require twice as much feed to make one pound gain in live weight as do uninfested pigs, then early recognition and treatment of the disease becomes an obvious economical necessity.
Plants And Asthma, Robert Dunlop Royce
Plants And Asthma, Robert Dunlop Royce
Journal of the Department of Agriculture, Western Australia, Series 4
ASTHMA is defined in the dictionary as being a disease characterised by recurring attacks of difficulty in breathing, and the causes are stated to include the inhalation of dust, or the odour of plants, flowers or animals.
Hay fever is a similar condition and this too, is caused by plants, usually at the time of flowering, when large quantities of pollen are produced.
Brucellosis Can Cause Contagious Abortion In Cattle And Undulant Fever In Man, F C. Wilkinson
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.
