Ticks Affecting Animals In Australia, J Shilkin

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

WHILE there are many external parasites affecting animals in Australia, information in regard to their geographical distribution and incidence is far from complete.

However, there is little doubt that the ticks, and in particular, the cattle tick, are the most important of these parasites in Australia.

We are fortunate that many species are not present in this country, as some of them are carriers of serious diseases of both man and animals.

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.

Time Of Lambing, W L. Mcgarry, I. K. Scott

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

THE time chosen for lambing depends on many factors, and the final decision rests with the individual flock-owner who has to consider how different times fit in with the overall programme of farm operations; how they will influence the marking percentage, the marketing, the thrift of his sheep and most important, how they influence the profit from his sheep operations.

Pulpy Kidney Is Still A Sheep Killer, F C. Wilkinson

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

ALTHOUGH considerable publicity has been given to methods of control by vaccination, numbers of sheep are lost every year in outbreaks of infectious enterotoxaemia— the disease commonly known as "pulpy kidney."

A Successful Campaign Against The Euro, E H M Ealey, T. M. Richardson

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

RESULTS from a five-year research programme carried out by the C.S.I.R.O. on the Abydos-Woodstock Pastoral Research Station indicated that euros could be controlled in a practical and economic way by the traditional method of water poisoning,

if it was continued for an extended period and carried out over a large area. Smallscale trials supported this claim, but no opportunity had occurred to assess the practicability of a large-scale poisoning operation.

Milk Fever (Hypocalcaemia) Of Cows, Department Of Agriculture, Western Australia

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

THE condition known as milk fever is almost essentially a disease of highly productive adult milking cows at the time of calving.

It is characterised by a low blood calcium level causing a sudden general depression of consciousness of the cow and muscular paralysis.

Without treatment most cases result in the death of the cow.

Pig Pox : Its Presence In W.A. Is Suspected But Not Yet Confirmed, F C. Wilkinson

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

A PIG-FARMER recently asked for in-information on pig-pox and inquired whether the disease occurs in Western Australia.

The first part of the question is easily answered, as pig-pox is a typical pox disease caused by a virus and resulting in roundish, red areas appearing on the pig's skin.

The disease is in fact very similar to the other more commonly known pox diseases—chicken-pox in the human population, fowl-pox in poultry and cow-pox in cattle.
