Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre Jan 1989

Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre

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

The idea of integrating the Kimberley cattle industry with that in the south-west of Western Australia is no new, but until recently it had not been critically evaluated.

Over the past eight years the Department of Agriculture's Beef Cattle Branch has been assessing the performance of Kimberley cattle transported south for finishing in the agricultural areas.

This research has show that Kimberley weaners can be finished in the south, and that under the present (December 1988) economic conditions it is more profitable than running breeding cattle in the south-west and comparable with fattening store steers.


Direct Selling Is A Plus For Cattle Producers, P G. Frapple Jan 1989

Direct Selling Is A Plus For Cattle Producers, P G. Frapple

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

The aim when marketing cattle is to maximise the net return with the minimum level of risk. To do this a producer needs an accurate description of the stock for sale and information on the likely gross returns and costs of selling through the different marketing systems.

Since producers' selling costs and processors' buying costs are lower in direct sales, it is more likely that net returns from direct delivery will be higher.


Increasing Profit On Dairy Farms, G R. Olney, Warren Standing Jan 1989

Increasing Profit On Dairy Farms, G R. Olney, Warren Standing

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

Farmers continually make decisions on all aspects of their farms that influence profit. For dairy farmers these include the number of cows, calving pattern, level and type of supplementary feeding, area of each pasture type and fodder crop, and the areas for hay or silage, or both. The extent and type of the beef sideline operations also influence the overall profitability of the farm.

The WesternAustralian Dairy Farm Model (WADFM) is a whole farm model developed by the Western Australian Department of Agriculture to help farmers maximise profits by considering all effects of such decisions on the farm.


Economic Impact Of Growing Phomopsis-Resistant Lupins, J M. Warren, Jeremy Allen, Wallace Cowling Jan 1989

Economic Impact Of Growing Phomopsis-Resistant Lupins, J M. Warren, Jeremy Allen, Wallace Cowling

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

The planting of Phomopsis-resistant lupins will increase net farm income. They will also alter the traditional blend of pastures and cropping, depending on grain and wool prices. In mixed farming areas of Western Australia's southern wheatbelt, they will allow more land to be sown to lupins rather than cereals on farms in which the lack of sheep feed over summer severely restricts wool production.

The benefits of Phompsis-resistant lupins arise from a reduction in sheep deaths due to lupinosis, a longer safe grazing period (free from lupinosis) on lupin stubbles, a decrease in the need for supplementary sheep feed over …


Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater Jan 1989

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

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

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …


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.


Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone Jan 1989

Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone

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

For the past few years, the Department of Agriculture has been fattening cattle on the forage shrub leucaena which is grown under irrigation with pangola grass. About 400ha of leucaena is under commercial production in the Kimberley.

Cattle grazing leucaena show promising growth rates but other problems need to be overcome before its use is more widely adopted. Leucaena establishes slowly. It is also costly to transport fattened cattle to southern abbatoirs.


Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare Jan 1989

Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare

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

Sheep fed cereal grains as an energy source over summer usually need added calcium because cereal grains are generally low in calcium (for example, 0.03 per cent calcium compared to 0.26 per cent phosphorus), and there may not be a natural source such as clover, weeds, leafy stubble or edible bush in the paddock.

The safestt and most effective calcium supplement is finely ground limestone added to the feed, but some farmers have used other sources of calcium such as gypsum and superphosphate in this manner.


The Sandplain Lupin : Its Nutritional Value And Grazing Management, P W. Morcombe Jan 1989

The Sandplain Lupin : Its Nutritional Value And Grazing Management, P W. Morcombe

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

The sandplain lupin or Western Australian blue lupin (Lupinus cosentinii) was introduced to the West Midlands at the turn of the last century. Since that time it has been used as a self-regenerating summer forage for sheep and cattle.

Being deep rooted, it has adapted well to the sandy soils from Perth to Northampton, and plantings now cover more than 100,000 ha.

As few other improved pasture species will persist on these deep sands the sandplain lupin provides an important source of summer feed for grazing livestock. A stand can be grazed throughout summer at stocking rates of 10 to …


Intensive Animal Industries In The Peel-Harvey Catchment, R W. Payne Jan 1989

Intensive Animal Industries In The Peel-Harvey Catchment, R W. Payne

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

The Swan coastal plain to the north and south of Perth is attractive for the intensive production of pigs and poultry for several reasons. It is close to markets, feed manufacturers and labour; has a less extreme climate than inland areas; and is underlain by a large reserve of high quality groundwater.

Because these are all intensive operations, large quantaties of nutrient-rich waste are produced over a very small area. They can severely damage ground and surface waters unless steps are taken to control the wastes which they produce.

This article oulines both the nature of intensive aniamal industries in …


Beefin : Maximizing Profits From Feeding Beef Cattle Out Of Season, R G. Grieve, David Barker, Jim May Jan 1989

Beefin : Maximizing Profits From Feeding Beef Cattle Out Of Season, R G. Grieve, David Barker, Jim May

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

BEEFIN is a computer model that formulates profit maximising diets for finishing beef cattle to a specified carcass weight and fat thickness. It predicts cattle growth rate, feed conversion ratio, final liveweight, number of days on feed and the amount of available feedstuffs required to finish cattle to specification, The diets fulfil the animal's energy, protien, mineral and roughage requirements.

BEEFIN also calculates a profit and loss budget for the enterprise, performs a sensitivity analysis on changes in the price for both cattle and feed and determines the changes in feed prices needed before the composition of the diet is …


Farmers' Estimations Of Sheep Weights To Calculate Drench Dose, R B. Besier, Diane Hopkins Jan 1989

Farmers' Estimations Of Sheep Weights To Calculate Drench Dose, R B. Besier, Diane Hopkins

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

Undersosing with drenches is a mojor cause of anthelmintic (drench) resistance in worm parasites of sheep.

When farmers use a drench at less than the recommended dose rate, some worms may survive, and their ability to resist treatment with the chemical involved is passed to their offspring. Over a period of time, matings between worms with different degrees of resistance can produce individuals able to resist the drench at the recommended dose rate or even higher.

Farmers must use adequate dose rates so that worms do not have a chance to survive treatment.


Weighing Scales For Sheep Do Pay, W D. Roberts Jan 1989

Weighing Scales For Sheep Do Pay, W D. Roberts

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

Sheep producers can improve production by using weighing scales and keeping accurate records of weights.

Withiut some objective measurement, such as weighing, producers have no accurate method of identifying the heaviest, lightest and average weight of a group of sheep.

They could try to esstimate weight by eye - but most people are poor judges of body weight.


Evaluation Of The Crack Approach For The Control Of Drench Resistance In Sheep Worms, J R. Edwards, Helen Chapman, Jon Dunsmore Jan 1989

Evaluation Of The Crack Approach For The Control Of Drench Resistance In Sheep Worms, J R. Edwards, Helen Chapman, Jon Dunsmore

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

The Department of Agriculture launched the CRACK approach to worm control in September 1985 in response to finding that anthelmintic (drench) resistant worms were present on 68 per cent of a random selection of Western Australian sheep farms.

The high cost of internal parasites in terms of lost production and drench costs, together with the high prevalence of resistant worms of farms, confirmed that changes were needed to existing parasite control measures in sheep.l


Capretto : A New Meat Industry, R J. Suiter Jan 1989

Capretto : A New Meat Industry, R J. Suiter

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

Capretto is the term the Italians use for the meat from a goat upto 20 weeks old. For centuries goat meat has featured on tables from the Mediterranean to asia and the Pacific Islands.

Western Australian premium quality capretto has a dressed weight of between 6 and 1kg. Its pinkish flesh is tender and leaner than sheep meat, so it's ideal for the health conscious.

This article describes a market development programme undertaken by the Department of Agriculture's Goat Industry Development Unit (GIDU) and the Australian Cashmere Growers Association's (ACGA) Meat Marketing Committee to establish a premium market for capretto …
