Teaser (Vasectomised) Rams : A Management Advantage, W L. Mcgarry, I. K. Stott

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

WITH normal late spring-early summer matings (October-December) teaser rams, correctly used, will give a more concentrated lambing.

This has been shown under Western Australian conditions in trials conducted at the Wongan Hills Research Station.

In one experiment a group of 100 ewes which had one per cent, of teasers for 14 days before the fertile rams went in, dropped 42 lambs in the first two weeks of lambing, compared with 17 lambs from 100 ewes that were not teased.

The use of teasers in all Research Station flocks is now routine practice.

Cattle Lice : Spray Now For Prevention, F C. Wilkinson

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

ALTHOUGH lice infestation can occur in any season of the year, the heaviest infestations are found during the winter.

This build up of lice infestation normally starts in the autumn but if the cattle are treated by spraying at this period, the majority of the lice are killed and the build up is prevented.

Thus the old saying "Prevention is better than cure" certainly applies with regard to cattle lice.

A Survey Of The Incidence Of Lupinosis In Sheep In The Dandaragan District In 1959, H G. Neil, W. J. Toms, C. M. Ralph

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

FOLLOWING widespread losses of sheep grazing on dry lupins, a survey of flockowners' experience with the disease was made by the Department of Agriculture in one of the districts most affected.

The idea of a survey originated from discussions with the President, Mr. K. E. Jones, and several other members of the Dandaragan Pasture Improvement Group.

The information obtained from the survey has provided a valuable factual basis for the design of laboratory and field experiments.

Pullorum-Tested Poultry Flocks : 1960, Department Of Agriculture, Western Australia

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

EARLY in 1955, an amendment to the Stock Diseases Act made blood-testing compulsory for all commercial breeding and hatchery flocks of poultry, and it was required that the incidence of infection, as determined by the last test prior to the commencement of hatching, must be less than two per cent.

Lupinosis In Sheep. 1. Laboratory Studies, M R. Gardiner, M. C. Nottle

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

IN earlier articles by Bennetts (1957, 1960), the clinical and pathological features of lupinosis, as seen in field outbreaks, were described.

The suggestion was made that the roughage portion of the lupin plants was responsible for the disease.

More recent observations suggest a relationship between parasitism and lupinosis.

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.

How Efficient Is Your Drenching Gun? Does It Deliver Sufficient Drench To Kill The Worms?, Department Of Agriculture, Western Australia

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

THE drenching gun pictured certainly doesn't. It is set to give two fluid ounces of drench (60 ccs approximately). However, when tested by squirting the fluid into a measuring cylinder, instead of down the sheep's gullet, it delivered only 30 ccs.

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.

Copper And Cobalt Deficiency Of Livestock In Western Australia, H. W. Bennetts

Journal of the Department of Agriculture, Western Australia, Series 3

Part 1. Distribution and effects

DISEASES of animals due to copper and cobalt deficiencies are well known in this State where much of the original work, on the cause of these conditions, was carried out. These investigations have been recorded elsewhere and described briefly in this Journal by Filmer and Underwood (1936), Bennetts (1935), (1937), (1940), (1941), (1942) and Bennetts et. al. (1939), (1942). During more recent years the distribution of these deficiencies in Western Australia has been surveyed in some detail. This survey has been made by field investigations and by chemical estimations of animal tissues and pastures from …

Recent Advances In Veterinary Medicine, J. Shilkin

Journal of the Department of Agriculture, Western Australia, Series 3

During and since the years of World War II many notable advances have been made in the treatment of human ills and in many cases a secondary development of these discoveries has been the use of new substances in the treatment of disease in domestic animals.
