Atrophic Rhinitis In Pigs, A R. Mercy

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

Severe atrophic rhinitis in pigs recurred recently in Australia after an apparent absence of some 20 years. The first of these recent cases occurred in a Westerm Australian herd in late 1984 and since then six other local herds have reported the disease. Severe atrophic rhinitis has also been seen recently in South Australia.

Atrophic rhinitis is a complex disease which causes degeneration of the nasal cavity, twisting of the snout and sometimes occasional bleeding from the nose.

It occurs only in pigs and severely affected animals may have a slower growth rate.

Two Causes Of Reduced Profit From Pigs, G A L Ward

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

LOSS of condition in a pig affects profits more severely than slow rate of growth.

Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain.

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.

Swine Erysipelas, G C De Chaneet

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

SWINE ERYSIPELAS, first diagnosed in Western Australia in 1960, has become a source of considerable loss to the pig industry.

Most losses have resulted from carcass condemnation at abattoirs because of arthritis caused by the erysipelas organism.

Did This Cause This? [Sarcoptic Mange Of Pigs], F C. Wilkinson

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

The mite on the left was detected by using a microscope with a magnification of 100 times to examine a skin scraping taken from the above pig.

This confirmed the suspicion that sarcoptic mange mites were the cause of the skin lesions.

Pig-Pox, F C. Wilkinson

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

THE lesions of pig-pox appear rather alarming when seen for the first time.

Fairly large red areas initially appear on the pig's skin followed later by scab formation, with healing two or three weeks after the first appearance of the disease.

Oedema Disease : A Cause Of Death Of Pigs In W.A, J Armstrong, P. Meyer

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

Within the last two years Oedema Disease ("Gut oedema") has been diagnosed as a cause of pig mortality in this State.

This article describes the nature, symptoms and methods of control of this disease.

Virus Pneumonia Of Pigs, J Craig, N. Macintyre

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

THIS disease is widespread in Western Australia and is undoubtedly a most serious source of economic loss to the pig industry.

The effects of virus pneumonia are such that in badly managed herds, widespread pneumonic outbreaks and deaths are common.

By contrast, in well managed herds, there is the more insidious problem of low or nil death rates, accompanied however by an appreciable fall in animal production.

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.

It Pays To Breed Your Own Pigs, Department Of Agriculture, Western Australia

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

ONE of the most important decisions to be made by a pig raiser is whether to purchase store pigs which he will fatten for market, or to breed his own stock.

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.

Swine Erysipelas : A Newly Reported Disease Of Pigs In Western Australia, M R. Gardiner

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

RECORDED in Western Australia for the first time last year, swine erysipelas is a potential menace to the pig raising industry.

This preliminary description is given to help farmers recognise its occurrence. I t is not known how widespread the disease might be, and farmers' co-operation is needed to estimate its extent.

Any suspected cases should be reported without delay.

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.
