Low Protein Rations Halve Bacon Pig Profits, N W. Godfrey Jan 1976

Low Protein Rations Halve Bacon Pig Profits, N W. Godfrey

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

For many years the department of agriculture has recommended that pig producers include meat meal or other protein concentrate in pig rations based on cereal grains. However, it is still common for pigs to be raised on cereal grains with little or no protein added.

Recent trials at the Department of Agriculture's Medina Pig Research Station have demonstrated the losses which can result from feeding pigs on low-protein cereal rations.


Calcium And Phosphorus Requirements In Lupin Seed Rations For Pigs, N W. Godfrey, A. R. Mercy Jan 1975

Calcium And Phosphorus Requirements In Lupin Seed Rations For Pigs, N W. Godfrey, A. R. Mercy

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

Seed of lupin varieties now available can be combined with wheat or barley to produce a balanced diet for growing/finishing pigs, and lupin seed has become a popular ingredient of pig rations.

As a protein concentrate, lupin seed is a satisfactory alternative to meatmeal, provided adequate amounts of calcium and phosphorus are added as supplements. Without the addition of these elements to rations of lupin seed and grain, a number of problems are likely to arise.

Trials at the Medina Pig Research Station have shown that Christmas Island rock phosphate is the cheapest and most convenient source of supplementary calcium …

Manufacture Of Monterey Cheese From Preacidified Milk, Faisal O. Mohamed May 1974

Manufacture Of Monterey Cheese From Preacidified Milk, Faisal O. Mohamed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd-whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused …

Lot Feeding Sheep In Sheds, H E. Fels, B. Malcolm Jan 1973

Lot Feeding Sheep In Sheds, H E. Fels, B. Malcolm

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

The need to gather and hold sheep for slaughter or live shipment led a West Australian company!, with the Department of Agriculture, to investigate the use of sheds for short term lot feeding of sheep. Preliminary examination suggested that feedlot sheds connected by a sheep footpath to the abattoirs, railway or saleyards could be cheaper as well as more practicable than continued use of holding paddocks.

The first week or two are commonly the most difficult in lot feeding sheep or cattle. Long-term indoor lot-feeding is a normal practice in some overseas countries but we did not know whether untrained …


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.


Grain Finishing Of Beef Cattle Grazing Dry Pasture Or Stubble, D J. Barker Jan 1971

Grain Finishing Of Beef Cattle Grazing Dry Pasture Or Stubble, D J. Barker

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

WHEAT quotas, poor wool prices and the availability of cheap grain on the farm have stimulated interest in grain finishing of cattle for out-of-season beef production. For many years, Animals turned off in the autumn-winter period have brought better prices than those sold in summer, at the end of the pasture flush.

Feeding grain supplements to cattle on dry pasture or stubble requires less capital than feedlotting and saves the cost of handling and processing roughage.

This article gives the essentials for grain supplementation of dry pasture or stubble but warns that grain finishing is unlikely to be profitable outside …


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.

Further details are available from the author


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 …


Basic Pig Breeding, P Mcnamara Jan 1971

Basic Pig Breeding, P Mcnamara

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

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.


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 …


Tender Wool Can Be Avoided, I G. Ralph Jan 1971

Tender Wool Can Be Avoided, I G. Ralph

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

THE production of tender wool which will not stand the tension and friction of the combing process can be reduced by an alteration in sheep management practices.

This is the finding of research carried out by the Sheep and Wool Branch of the Department of Agriculture over an eight-year period.


Dairy Calves Can Safely Be Fed Once A Day, R A. Bettenay Jan 1971

Dairy Calves Can Safely Be Fed Once A Day, R A. Bettenay

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

THE sale of milk rather than butterfat has increased greatly in the past few years and less than half the dairy farmers in Western Australia now own cream separators.

Feeding whole milk once a day can be successful for raising dairy calves, even in winter when calf rearing is most difficult.

A recent experiment at Wokalup Research Station showed that satisfactory weight gains can be achieved if liquid milk is fed only once a day from a very early age. Trial calves gained I lb a head a day over the 12 weeks of the experiment.

Once-a-day feeding greatly reduces …


Once A Day Calf Feeding, R A. Bettenay Jan 1971

Once A Day Calf Feeding, R A. Bettenay

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

Trials at Wokalup Research Station in 1970 proved that calves could be successfully reared with once a day liquid milk feeding, providing a high protein meal was continually available.

This trial was carried out to see if the high protein meal was essential for the success of the once a day feeding system.


Feeding Urea To Cattle, D J. Barker Jan 1970

Feeding Urea To Cattle, D J. Barker

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

RUMINANTS normally obtain the protein they require by digestion of the organisms that inhabit the forestomach (rumen), not by direct digestion of the dietary protein they chew up and swallow.

The organisms break down the dietary protein and then rebuild proteins in the form of more organisms.


Rearing Orphan Kangaroos, G L. Ward Jan 1970

Rearing Orphan Kangaroos, G L. Ward

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

LICENCES are required in Western Australia if certain kangaroos and all species of wallabies are kept in captivity, but orphaned young joeys often need care and hand feeding before they can be released to fend for themselves.


Rationing Standing Crops To Sheep, H E. Fels Jan 1970

Rationing Standing Crops To Sheep, H E. Fels

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

This experiment was done at Merredin Research Station to develop and test a method of rationing standing crops to sheep, and also to find whether rationing would reduce the sheep's water consumption.

The experiment involved 60 sheep on 12 one-acre plots of drought affected Gamenya wheat.


Surplus Cereal Crops For Sheep Feed, H E. Fels Jan 1970

Surplus Cereal Crops For Sheep Feed, H E. Fels

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

SINCE the introduction of wheat quotas many farmers have considered feeding unsaleable grain to sheep.

The three alternative methods of feeding this grain to sheep are

• as standing crops

• as grain supplements, fed in the paddock

• as grain plus hay, in a feedlot.


Crop Rationing : A Useful Drought Feeding Technique, H E. Fels Jan 1970

Crop Rationing : A Useful Drought Feeding Technique, H E. Fels

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

A TRIAL carried out during the 1969 drought demonstrated that rationing standing crop is a practical method of feeding it to sheep when feed is scarce.

Rationing will be mainly a drought feeding technique for that part of the crop which will definitely be used as sheep feed. Crop that may or may not be needed for sheep would normally be harvested and the grain kept as a contingency allowance.


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.


Supplementing Calves With Tallow : Results Of A Trial At Wokalup Research Station, Department Of Agriculture, Western Australia Jan 1970

Supplementing Calves With Tallow : Results Of A Trial At Wokalup Research Station, Department Of Agriculture, Western Australia

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

THE removal of butterfat from milk by separation, reduces the energy content of the milk by about 50 per cent., and must slow the growth of calves unless extra energy is provided from some other source.

In the dairying districts of Western Australia, there has been considerable interest in recent years in the addition of homogenised tallow to skim milk to provide extra energy.

Good calves have been produced by this means.


Carrying Prime Lambs Through Summer, R J. Suiter Jan 1970

Carrying Prime Lambs Through Summer, R J. Suiter

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

The annual lamb glut in September- October has caused many farmers to show interest in feed lotting and other methods of carrying over prime lambs for a higher priced market.

Unfortunately however, little information has been available on the necessary techniques under Western Australian conditions.

This report presents the results of the first year of a trial being conducted at Chapman Research Station to examine some of the problems associated with carrying lambs through the summer for later marketing.


Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin Jan 1970

Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin

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

THERE was a great deal of controversy throughout the summer of Western Australia's 1969-70 drought over the feeding of supplements other than grain to grazing sheep.

This report summarises some of the experiments carried out by this Department to investigate various artificial means of supplementing sheep grazing stubbles and dry summer pastures.

Further details of the experiments can be obtained by contacting the authors.

The results failed to demonstrate economic responses to urea supplements for grazing sheep.


The Feed Year Approach To Dairying, P T. Arkell Jan 1970

The Feed Year Approach To Dairying, P T. Arkell

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

Dairy cows have different food requirements at different times of the year.

Cows in peak production require much more food per day than dry cows. It is a waste of money to feed a dry cow more than it actually needs for maintenance.

Equally, it is uneconomic NOT to feed a producing cow enough to give maximum production.


Once Daily Calf Feeding Lowers Rearing Costs, Department Of Agriculture, Western Australia Jan 1970

Once Daily Calf Feeding Lowers Rearing Costs, Department Of Agriculture, Western Australia

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

The usual method of hand rearing dairy calves involves twice daily feeding of milk or milk substitutes.

This routine adds considerably to the labour necessary at milking time and may have prevented many farmers from putting much effort into dairy beef production.

The report below comes from a 1969 trial carried out at Bramley Research Station to see if once-daily calf feeding was as effective as twice daily feeding.

The trial's results should be considered as early findings from a series of trials being conducted into calf rearing regimes by both the Animal and Dairying Divisions of the Department of …


Dry Supplements Reduce Labour And Cost Of Calf Rearing, Department Of Agriculture, Western Australia Jan 1970

Dry Supplements Reduce Labour And Cost Of Calf Rearing, Department Of Agriculture, Western Australia

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

The conventional method of hand rearing dairy calves in Western Australia calls for the feeding of whole milk, skim milk and/or milk substitutes for periods of up to 16 weeks.

This requirement for milk and labour has often prevented beef production from becoming a major sideline on many wholemilk and butterfat farms.

The two trials reported below* were carried out at Bramley Research Station to see if milk consumption and time to weaning could be reduced by free-feeding hay and cereal based supplements.


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.


Look After The Tail Enders, B R. Beetson Jan 1970

Look After The Tail Enders, B R. Beetson

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

IN Department of Agriculture drought feeding trials last summer, shy feeders lost weight and died while the bigger sheep grew fat. When drafted off and fed separately the shy feeders ate their share and survived the summer.
