Vibriosis : Major Cause Of Infertility In Our Dairy Herds, J Craig

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

VIBRIOSIS is the main cause of infertility in West Australian dairy herds.

Its main feature is repeated return to service, and it can cause heavy financial losses.

The disease can be eliminated from a herd by the exclusive use of artificial insemination, or by the adoption of a "two herd" system.

Chronic Respiratory Disease Of Poultry In Western Australia, M R. Gardiner, R. V. Vagg

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

Widespread chronic respiratory disease was revealed in a survey of respiratory infections in Perth metropolitan area poultry flocks.

Most occur in early or midsummer and cause a serious fall in egg production. Return to full lay after the infection is usually slow.

While these infections can cause production losses in flocks which are under heavy stress, none of the more serious forms of chronic respiratory disease was found.

This gives encouragement for future control of the disease in Western Australia.

Chick Management, D F. Hessels

Stress Factors In Pig Raising, P C. Beck

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

THE pig raiser who wishes to attain the best possible growth performance from his pigs must recognise factors other than the basic ones of good nutrition and bredin capacity.

These are "stress factors"—minor factors of husbandry which can greatly damage health and limit the growth rate.

A Modified Copper Hot Water System, F J. Fielder

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

A good supply of hot and boiling water for cleansing and sterilising utensils is essential for hygienic milk production.

Dairy Instructor F. Fielder, M.D.D., describes an efficient and economical modification of a copper hot water system for this purpose.

SINGLE copper units of 14 or 16 gallon capacity to supply hot and boiling water for the dairy are no longer good enough for most dairy farms.

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.

They are mycotic dermatitis (lumpy wool) and fleece rot. Both conditions damage the fleece and render affected sheep susceptible to blowfly strike.

A Survey Of The Helminth Parasites Of Pheasants From Brown County, South Dakota, Donald E. Gilbertson

Electronic Theses and Dissertations

This paper presents a study of the helminth endoparasite of the Chinese or ring-necked pheasant (Phasianus colchicus). The digestive and respiratory tracts of 262 pheasants, all of which were collected in Brown County, South Dakota, were examined. Collections were ,made from January, 1961, through November of the same year. The problem was divided as follows: (1) locating and Identifying the helminth parasites, (2) relating parasitism to the age of the birds, (3) ascertaining the seasonal distribution of the parasites, and (4) determining what gross pathological changes were due to parasitism. Previous to this study, little or no literature was available …

Ovine Vibriosis : A New Cause Of Sheep Infertility, M R. Gardiner, M. E. Nairn, I. J. Miller

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

Vibrionic abortion of sheep has caused heavy losses in a number of wheatbelt flocks. In several flocks up to 50 per cent, of the ewes aborted as a result of this newly reported disease.

This article gives the history of the disease in this State, and describes the symptoms for the benefit of other farmers whose flocks may be affected. Ewes become immune after the first attack.

Nebraska Beef Cattle Reports

Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.

Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …

Mulesing At Lamb Marking Time, M Butler

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

REALISING that mulesing and tailstripping of sheep is the most effective system devised to counteract the loss and damage caused by blowfly strike in their sheep, many farmers and pastoralists are now incorporating it as standard practice in their system of sheep husbandry.

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.

This treatment can and should be carried out as farm or station routine practice in the same way as are other accepted management practices, such as lambmarking, drenching, etc.

The Dehorning Of Cattle, J Shilkin

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.

Post Dipping Lameness In Sheep, I J. Miller
