Weaning Kimberley Cattle Pays Off, D Pratchett, Stuart Young Jan 1989

Weaning Kimberley Cattle Pays Off, D Pratchett, Stuart Young

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

Research results show that weaning Kimberley calves when they reach 140kg liveweight is one way of increasing herd productivity by changing management practices. However, removing the bulls from the breeding herd, rather than running them with the cows ywear round as is the practice, does not increase branding percentage.


Farm Grazing Levels, Department Of Agriculture, Western Australia Jan 1972

Farm Grazing Levels, Department Of Agriculture, Western Australia

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

Stocking rates in many dairying areas are so low that the Division has established nine grazing level demonstrations in various areas.

Their aim is to demonstrate that higher stocking rates are practical on existing farms.


Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker Jan 1971

Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker

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

FEEDLOTS are small enclosures where all of the animal's feed is supplied from an outside source. Compared with grazing, feedlotting is an expensive method of beef production.

This article gives a guide to the requirements for establishment and management of a farm feedlot, especially the basic equipment and materials, the type of cattle most suited to feedlotting, rations and feeding techniques.

The author warns that skill and experience are needed to run a feedlot and describes feedlotting as an expensive method of beef raising when compared with grazing.

When Is A Cattle Feedlot Profitable?, J T. Stoate Jan 1971

When Is A Cattle Feedlot Profitable?, J T. Stoate

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

THE current surge of interest in feedlots stems from low coarse grain prices and comparatively low early summer baby beef prices. Cattle raisers sense the opportunity for higher prices by holding the cattle on the farm over summer and autumn, and grain producers see better returns from barley and oats fed to cattle than sold as grain.

This article examines the profitability of cattle feedlots and presents sample budgets for two typical situations—the farmer who produces his own cattle but buys grain, and the cereal grower who produces grain but buys in cattle for finishing in a feedlot.

A ready …


Dairy Beef Shows Healthy Profits, D J. Barker Jan 1971

Dairy Beef Shows Healthy Profits, D J. Barker

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

The October, 1970, issue of the Journal of Agriculture included results from the first year of a dairy beef production trial at Bramley Research Station.

This report presents results from the trial's second year, during which two levels of pasture utilisation were tested. The trial is now in its third year.


Thinking Of Pigs To Raise Your Income?, P Mcnamara Jan 1971

Thinking Of Pigs To Raise Your Income?, P Mcnamara

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

WHEAT quotas and low wool prices have caused many farmers to look to pigs to consume homegrown grain and to lift their incomes. However, with sow numbers at a record level, is it possible for a wheatbelt farmer to raise pigs profitably?

Because of his access to cheap grain, the wheatbelt farmer may be able to make a good profit on each pig sold. This could make pigmeat production a useful sideline on the farm, providing the farmer produces only lean pigs. There is no market for overfat pigs.

This article gives some hints on production of pigs on cereal …


Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia Jan 1970

Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia

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

THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.

The profit from selling beef must be compared with that from selling excess calves off their mothers.

Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.


High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter Jan 1970

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.


High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan Jan 1969

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.


Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis Jan 1967

Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis

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

THE 1965 Pardelup cattle stocking rate trial was conducted with Hereford cross yearling steers on annual pasture of Mt. Barker sub. clover, Wirnmera ryegrass and various volunteer annual species.

This was topdressed with 186 lb. of superphosphate per acre in mid March.


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.


Feeding Urea To Dairy Cows, R A. Bettenay Jan 1967

Feeding Urea To Dairy Cows, R A. Bettenay

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

IT has been known for some years that the ruminant animal, through the agency of microflora in the rumen, has the ability to use urea as a source of nitrogen, and to convert some of this to protein.


More Sheep Per Acre, Department Of Agriculture, Western Australia Jan 1966

More Sheep Per Acre, Department Of Agriculture, Western Australia

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

In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.

The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.


Meadow Hay For The Dairy Herd, F E. Ryan Jan 1966

Meadow Hay For The Dairy Herd, F E. Ryan

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

CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.


The First Year Of A Cattle Stocking Rate Trial At Pardelup, R Sprivulis Jan 1966

The First Year Of A Cattle Stocking Rate Trial At Pardelup, R Sprivulis

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

AS a first step towards the study of pasture utilisation by cattle, a simple trial was commenced at the Pardelup Prison Farm in 1964.

The trial is carried out with Poll Hereford cross steers set stocked on Mt. Barker subterranean-clover and Wimmera ryegrass pasture.

It will be repeated for several seasons.

IN May 1963, some three weeks after germination, a 4th year stand of Cyprus barrel medic was stocked with Merino wethers.

These same sheep are still grazing the area after three years.


Good Management For The Springers Pays Dividends, J Y. Langdon Jan 1966

Good Management For The Springers Pays Dividends, J Y. Langdon

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

This article gives a striking example of the advantages of calving cows in good and rising condition—and explains why condition around calving time is so important.

ALTHOUGH most farmers know that cows calving in good and improving condition will give higher yields than those calving in poor condition, few use this knowledge to improve the production from their cows.


Continuous Grazing On Rose Clover At Northampton, R J. Parkin Jan 1966

Continuous Grazing On Rose Clover At Northampton, R J. Parkin

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

BECAUSE of its upright growth habit, it is often thought that rose clover may require some form of specialised grazing management.

It has also been said that the sheep find the plant and in particular the seed head, undesirable in the dry stages.

However, more recent observations refute this (Bailey 1966). The present commonly-grown strains of rose clover are later flowering generally than the medics or Geraldton subterranean clover and stay green later in the season.

Dairy Farming In The Busselton-Margaret River District. Part 3. Fodder Conservation, R A. Bettenay

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

An analysis of fodder conservation indicates that farmers in the Busselton-Margaret River district are conserving less than half the amount of fodder considered desirable.—Third in a series reporting a survey of farm practices in the district.


Pigs Have A Place In The Dairying Areas, P Mcnamara Jan 1964

Pigs Have A Place In The Dairying Areas, P Mcnamara

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

Pig-keeping could become a much more important feature on South-West dairy farms in the future with the enterprise as a definite farm-unit having a considerable effect on income.

There are indications also that the collection of bulk skim milk and whey for pig feeding will increase in the future. This could make way for the efficient specialist operating large pig raising units close to the source of supply.

In this article. Pig Husbandry Adviser P. McNamara, B.A. (Cantab.) examines pig-keeping in the South-West and makes suggestions on the part that pigs can play on the modem dairy farm.
