Protein Plus has commenced as a collaboration between the Department of Agriculture and the CSIRO Division of Livestock Industries. The project is aimed at investigating the causes of Western Australia's problems with low summer milk protein levels, and finding management solutions for farmers.
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Journal of the Department of Agriculture, Western Australia, Series 4
In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …
Dairy Herd Recording, R D. Maughan, Frank Treasure
Dairy Herd Recording, R D. Maughan, Frank Treasure
Journal of the Department of Agriculture, Western Australia, Series 4
Fifty-five percent or 320 of Western Australia's daity farmers participate in the dairy herd recording, the highest percentage of dairy farmers who use herd recording in any Australian State.
Herd recording provides the dairy farmer with an accurate measure and record of individual caw and hers performance. Information on milk, fat and protein production, the level of mastitis infection and breeding values assists the dairy farmer with his herd management and selection of cows. The herd recording facility is provided by the Herd Improvement Service and the fees are based on an annual herd fee and a lactation fee for …
Meat From The Dairy Herd, R A. Bettenay
Meat From The Dairy Herd, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
Beef raising is a profitable sideline for many West Australian dairy farmers and gives their farming operation flexibility and versatility.
With suitable management and feeding the weight gains and consumer acceptance of dairy beef allow it to compete strongly with beef from other sources.
The breeds most common on W.A. dairy farms are well suited to beef production.
Farm Grazing Levels, Department Of Agriculture, Western Australia
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.
Dairy Calves Can Safely Be Fed Once A Day, R A. Bettenay
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 …
Dairy Beef Shows Healthy Profits, D J. Barker
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.
Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia
Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
EVERY DAIRY farmer knows how much he spends on the treatment of cows affected with mastitis, but the actual loss in production is more difficult to estimate.
As part of the current mastitis research programme the Department of Agriculture's Animal and Dairying Divisions surveyed 37 dairy herds with a believed high incidence of mastitis.
The Feed Year Approach To Dairying, P T. Arkell
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.
More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia
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.
Can Mastitis Be Eliminated?, F C. Wilkinson
Can Mastitis Be Eliminated?, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
Can mastitis be eliminated from a dairy herd? The results of a 12-month continuous study of four commercial herds show that it could be done.
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.
Mastitis In Western Australian Dairy Cattle, Department Of Agriculture, Western Australia
Mastitis In Western Australian Dairy Cattle, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
IN 1964/65, as a first step towards a State-wide mastitis control programme, the Department of Agriculture undertook a survey of mastitis in West Australian dairy herds.
The survey was designed to obtain a clear picture of the incidence and severity of the disease and is the most comprehensive mastitis survey carried out in Australia.
Feeding Urea To Dairy Cows, R A. Bettenay
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.
Coccidiosis Of Calves, W A. Halhead
Coccidiosis Of Calves, W A. Halhead
Journal of the Department of Agriculture, Western Australia, Series 4
Coccidiosis is one of the commonest causes of calf loss and debility on South-West dairy farms.
Treatment and control are simple once the nature of the disease is understood.
Meadow Hay For The Dairy Herd, F E. Ryan
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.
Good Management For The Springers Pays Dividends, J Y. Langdon
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.
Rules Of The Western Australian Pure Bred Dairy Cattle Production Recording Scheme, Department Of Agriculture, Western Australia
Rules Of The Western Australian Pure Bred Dairy Cattle Production Recording Scheme, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
REVISION of these rules was necessary because of the amalgamation of the field work with that of Grade Herd Recording.
Adjustments have been made to facilitate more expeditious handling of records in the Department's Head Office.
Other minor changes have been made to bring the rules into line with present day practice.
Animal Husbandry Research At Bramley, Department Of Agriculture, Western Australia
Animal Husbandry Research At Bramley, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
A progress report of animal husbandry investigations at the Bramley Animal Husbandry Research Station, Margaret River.
BRAMLEY RESEARCH STATION is four miles north of Margaret River.
The average annual rainfall of 45 inches falls mainly in the winter, providing a seven-month growing season which starts in March or April.
The June-July period is excessively wet, causing extensive waterlogging of the soils.
Recording Figures Are No Check On Factory Returns, R A. Bettenay
Recording Figures Are No Check On Factory Returns, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
MANY dairy farmers who use Grade Herd Recording are in the habit of comparing their Grade Herd Recording results with returns obtained from a factory.
Where the two returns show some discrepancy the inference drawn always appears to be that whichever credits the herd with the lower return is at fault—either "the recorder is not doing the job properly" or "the factory is robbing the farmer of his just returns."
Rearing Dairy Calves, R A. Bettenay
Rearing Dairy Calves, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
ON Western Australian dairy farms the wastage rate of dairy cows is probably more than 20 per cent, and this, coupled with the tendency towards bigger herds, means that well over half of the heifer calves born should be reared for herd replacements.
Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Seed And Pasture Rates For New Dairy Pastures, F E. Ryan
Journal of the Department of Agriculture, Western Australia, Series 4
THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.
Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.
Breeding Records For Dairy Cattle, P B. Lewis
Breeding Records For Dairy Cattle, P B. Lewis
Journal of the Department of Agriculture, Western Australia, Series 4
A N Y business needs records to show up inefficiencies and to indicate where and/or when danger points are being reached.
One record which can be of much use to the dairy farmer is the cow breeding record.
Grade Herd Recording, 1963-64, Maurice C. Cullity
Grade Herd Recording, 1963-64, Maurice C. Cullity
Journal of the Department of Agriculture, Western Australia, Series 4
A review of Grade Herd Recording during the 1963-64 season.
THERE was a substantial increase in the number of cows which were recorded in 1963-64 compared with 1962-63 (23,520 and 22,635 respectively).
This season's figure represents 20.4 per cent, of all cows in the dairying districts.
The number of cows which completed lactation and therefore whose yields were included in the averages, rose from 17,258 to 19,011.
Udder Preparation For Milking, W G. Robinson
Udder Preparation For Milking, W G. Robinson
Journal of the Department of Agriculture, Western Australia, Series 4
REGULAR routine methods of preparing the udder for milking hare long been recognised as essential for good "let down" of milk.
The biggest problem so far has been to combat the spread of disease, in particular mastitis from udder to udder by the milker's hands or the udder washing cloths.
Does Herd Recording Help Farmers Improve Husbandry, Maurice C. Cullity
Does Herd Recording Help Farmers Improve Husbandry, Maurice C. Cullity
Journal of the Department of Agriculture, Western Australia, Series 4
THE proportion of the dairy herds throughout Australia that are being production recorded is low.
This is particularly surprising when the large amount of propaganda encouraging farmers to herd test is considered.
Grade Herd Recording : 1962-63, Maurice C. Cullity
Grade Herd Recording : 1962-63, Maurice C. Cullity
Journal of the Department of Agriculture, Western Australia, Series 4
A poor season coupled with a 16 per cent, increase in the number of cows tested during 1962-63 led to a drop in the average yields of cows in the Grade Herd Recording Scheme.
Meadow Hay, Department Of Agriculture, Western Australia
Meadow Hay, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
rriHE nutritive value of pasture is high in early spring and remains so until early flowering.
After this the protein content falls rapidly, the fibre content rises and the plants become more lignifled and their digestibility reduced.
Vibriosis : Major Cause Of Infertility In Our Dairy Herds, J Craig
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.
Selecting A Herd Sire, R A. Bettenay
Selecting A Herd Sire, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
THERE is now ample evidence that most of the differences in production between herds are determined by feeding and management, with differences in genetic merit playing a relatively minor role.
It seems that the quickest way to increase production is by improved feeding, whilst in some herds much production is being lost by faulty milking techniques.
