New Developments In Footrot Control, R B. Richards, L. J. Depiazzi, R. V. R. Gwynn

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

The eradication policy for footrot in sheep adopted by the Western Australian Department of Agriculture has produced an overall decline in the number of properties with the disease.

Our knowledge of the disease has improved substantially as a result of the research conducted at the Slabany Regional Veterinary Laboratory in recent years. Laboratory tests now sssist stock inspectors and veterinary officers to distinguish between different forms of footrot and to quarantine and eradicate accordingly.

The recent discovery of more effective foot-bathing solutions by officers of the Victorian Department of Agriculture will greatly assist further eradication procedures.

Lumpy Wool May Increase By Dipping : Research Roundup, Department Of Agriculture, Western Australia

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

Lumpy wool, or mycotic dermatitis, is an infectious disease on the skin of the sheep caused by the bacterium Dermatophilus conglensis. The organism invades the wool and hair follicles, causing formation of skin lesions producing scabby material which binds the wool fibres into a hard mass.

Research shows that 'dipping' may increase the incidence of lumpy wool with some chemicals a greater risk than others.

Chemical Sterilisers In The Dairy Industry, D N. Tulloch, N. Ingleton

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

There is concern in the cheese industry that residues from new chemical sterilisers used by dairy farmers could affect cheese making processes.

The sterilisers could also affect tests for antibiotic residues in milk. The responsibility of seeing that chemical sterilisers do not enter the milk belongs to the dairy farmers.

They should follow the manufacturers' recommendations and use the chemicals with care.

Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona. These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960. The Lake Mead studies produced the following general points of …
