Mycotic Dermatitis (Lumpy Wool) And Fleece Rot Of Sheep, J Shilkin

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

Matted and sometimes discoloured specimens of wool are often received at the Department of Agriculture during seasons of heavy rainfall.

Two similar but quite distinct diseases are recognised as having caused this condition.

Detergents For The Dairy Farm, H Maslin

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

CLEANLINESS in both the physical and bacteriological sense is essential to the production of high quality dairy products, and high quality in these products is essential to both the health of the community and the successful and economic operation of the industry.

Detergents have an important place in maintaining dairy hygiene—but they must be properly used if they are to be really effective.

In this article Dairy Instructor H. Maslin, M.D.D., describes the qualities of a good dairy detergent and explains how it should be fitted into the regular cleaning routine.

Local Control Of Crows By Trapping, C J. Woodbury

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

THE common crow seen frequently around farms in the South-West is the raven (Corvus coronoides) whilst the pest of pastoral areas is the true Australian crow (Corvus cecilae).

Farmers and pastoralists, although recognising the importance of these birds as scavengers and destroyers of insects, particularly grasshoppers, sometimes for one reason or another, wish to reduce their numbers over a localised area.

Baiting with phosphorus has been used in the past, but the purpose of this article is to describe and illustrate a type of trap which has become universally known as the "Australian Crow Trap."

Why Poor Prices For Pigs?, P C. Beck

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

A rapid increase in pig numbers and an unfavourable export situation have precipitated the present depression in the pig industry. Concentration on quality production and a gradual reduction in numbers should bring back a more stable situation, says Dairy Division pig specialist P. Beck. Big fluctuations in the pig population—the basic cause of cycles of boom and depression in the industry—would be avoided if more farmers adopted a fixed farm level policy towards the industry.

Mulesing Pays, W L. Mcgarry

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

THERE is little doubt that the combined mules and tail strip treatment is still far ahead of all other blowfly control measures.

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

THE dehorning of cattle, both dairy and beef, has many advantages.

Breeders of stud cattle frequently claim that removal of the horns spoils the appearance of show animals and stress that the practice is cruel.

Whilst both these statements may, to some extent, be true, the advantages of the practice far outweigh any disadvantages.

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.

Lambing Problems In Summer Rainfall Areas, H Suijdendorp

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

LOW lambing percentages have become a serious problem in the summer rainfall areas in the North-West of Western Australia.
