Choosing Your Lambing Time, T Marshall Jan 1970

Choosing Your Lambing Time, T Marshall

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

SHEEP, pastures and labour are the major resources of the sheep enterprise but their productivity is greatly affected by the timing of operations associated with them.

This article discusses how the lambing time can be chosen to get maximum use from each resource.


A Guide To Pig Feeding, P Mcnamara Jan 1967

A Guide To Pig Feeding, P Mcnamara

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

FOOD is by far the greatest cost in pig production, accounting for between 60 per cent, and 75 per cent, of the total cost, and for this reason it is important that the basic principles of feeding be understood.

Growth Of The Broiler Industry In W.A, D F. Hessels

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

THE production of poultry meat in W.A. before 1956 was only a side-line for egg producers or small, mixed farmers.

Most of the meat available was made up of culled hens, first cross cockerels and some heavy breed birds.


Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson Jan 1965

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

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

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.


A Sheep Management Calendar For Lambing On Green Feed, H E. Fels, J. A. C. Smith Jan 1965

A Sheep Management Calendar For Lambing On Green Feed, H E. Fels, J. A. C. Smith

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons Jan 1964

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons

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

IN the summer rainfall region of the pastoral areas lambs are too often born too late to ensure their survival.

In good seasons with a fair measure of winter rain more late lambs will survive, but losses are still serious. The only solution to this problem is to make sure lambs drop in May-June.

But the presence of late and often unmarked lambs at mating time is a disturbing influence, which makes it hard to advance the established mating pattern.


Poultry : Toxic Factors In Protein Supplements, D F. Hessels Jan 1964

Poultry : Toxic Factors In Protein Supplements, D F. Hessels

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

The toxic effect of low quality and/or stale protein supplements can be a problem in the poultry industry.

This article describes trials carried out to assess their importance in Western Australia.

Acetonaemia In Dairy Cows, F C. Wilkinson Jan 1963

Acetonaemia In Dairy Cows, F C. Wilkinson

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

ACETONAEMIA is a common disease of newly calved cows in the dairying districts of Western Australia.

Affected cows practically dry off and lose a lot of body condition; these are the main causes of loss to the owners.


Weaning And Weaner Management, R J. Lightfoot Jan 1962

Weaning And Weaner Management, R J. Lightfoot

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

MOST of Western Australia's Merino flock owners wean their lambs in the months of August, September and October.

Too often this is done indiscriminately to fit in with other operations, or lambs are left on their mothers for long: periods until the ewes are remated.


A Simple Feeding Guide : Balanced Rations For Dairy Cows, K Needham Jan 1962

A Simple Feeding Guide : Balanced Rations For Dairy Cows, K Needham

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

MANY technical articles have been written on the nutrition of dairy cattle and the methods employed in compounding a balanced ration have often been explained.

This article aims to present the principles of compounding a balanced ration in a simplified form, and suggests rations which should be easily adopted on any dairy farm.


Can Worms Be Controlled By Correct Feeding?, Laurence C. Snook Jan 1961

Can Worms Be Controlled By Correct Feeding?, Laurence C. Snook

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

THE extensive losses which result from the ravages of internal parasites are a matter of serious concern.

Livestock owners realise this all too well and welcome advice concerning control measures which can be adopted. Unfortunately, it is not possible to give clear cut advice on the subject.

Much publicity is given to the use of drugs which will expel the worms. Various systems of strategic drenching have been developed.

It is well to remember, however, that drenching is only one of many methods which can be used to control worm infestation.

In this talk attention will be concentrated on experimental …


Lambing Problems In Summer Rainfall Areas, H Suijdendorp Jan 1961

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.

Largely as a result of poor nutrition of the lambing ewes, lamb marking figures have fallen to the stage where keeping up stock numbers is extremely difficult.


Vitamins And Their Relationship To Animal Health, J Shilkin Jan 1961

Vitamins And Their Relationship To Animal Health, J Shilkin

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

NUTRITIONAL problems are assuming more and more importance in stock as the years progress and while much stress is sometimes placed on the role of vitamins in nutrition, one should not lose sight of the fact that they are only part of a balanced ration which should include other constituents, such as proteins, carbohydrates and fats in suitable proportions.


The Feeding Of Pigs In The Wheatbelt, S R. Dunstan Jan 1961

The Feeding Of Pigs In The Wheatbelt, S R. Dunstan

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

ONE of the biggest costs in pig-meat production is feeding, and it is of vital importance for the farmer to understand what presents a balanced and economic ration, in order that he can take steps to achieve maximum efficiency.


White Muscle Disease Of Sheep : Symptoms And Pathology, M R. Gardiner Jan 1961

White Muscle Disease Of Sheep : Symptoms And Pathology, M R. Gardiner

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

WHITE Muscle Disease (WMD) was recognised for the first time in Western Australian sheep during the winter of 1960.

The first outbreak occurred on a property in the South Stirling district in the middle of July and this was followed by outbreaks in August, September and early October, at Mayanup, Kendenup, Mt. Barker, Duranillin, Kojonup, South Stirling and Pinjarra.


It Pays To Breed Your Own Pigs, Department Of Agriculture, Western Australia Jan 1961

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.


Plan For Quality In Silage, Department Of Agriculture, Western Australia Jan 1961

Plan For Quality In Silage, Department Of Agriculture, Western Australia

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

SILAGE making time is fast approaching in the South-West.

Last minute preparations before harvesting will help avoid delays at the time of making this valuable fodder, thereby reducing the amount of costly spoilage caused by hold-ups.


Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett Jan 1961

Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett

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

A DECLINE in carrying capacity has occurred in large areas of the Pilbara district of the North-West, due to the decrease in palatable plants and the increase in unpalatable ones.

The relative palatability of the various species to sheep is therefore a matter of considerable importance to pastoralists.


Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan Jan 1961

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

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

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.


Correcting Cobalt Deficiency, Laurence C. Snook Jan 1961

Correcting Cobalt Deficiency, Laurence C. Snook

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

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.


The Care Of The Breeding Sow, P C. Beck Jan 1960

The Care Of The Breeding Sow, P C. Beck

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

PIG-RAISING is a specialised field of animal production, which, to be profitable must incorporate both a scientific and a practical approach.

These two factors must be complementary, for without a sound practical approach, the value of the scientific principles involved, e.g., in breeding and compounding rations would accordingly be reduced.


Help Those Lambs To Live, C J. Spencer Jan 1960

Help Those Lambs To Live, C J. Spencer

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

IN almost all breeding flocks the most serious stage of sheep loss is from birth to three days of age with the majority of these losses occurring at birth or during the first day.

The number of lambs lost at this time is rarely known, but survey work shows that on most properties ten to twenty of every hundred lambs born are dead before three days of age.

The economic importance of such losses cannot be emphasised too much. Money has been expended for rams as sires, while the ewes have received extra feed and have had their wool production …


A Survey Of The Incidence Of Lupinosis In Sheep In The Dandaragan District In 1959, H G. Neil, W. J. Toms, C. M. Ralph Jan 1960

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.


Milk Fever (Hypocalcaemia) Of Cows, Department Of Agriculture, Western Australia Jan 1960

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.
