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 …

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 …

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

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.

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.

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

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 …

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 …

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.

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.

Beef In Western Australia, Western Australian Department Of Agriculture

Bulletins 4000 -

Western Australia's first European settlers introduced cattle for both milk and meat soon after a permanent colony was established in 1829. From this time, most Western Australian beef was produced as a side-line of t he dairy industry.

Bulletin No 4151 - Pigs In Western Australia, N W. Godfrey, B M. Goss, H. G. Payne

Bulletins 4000 -

Pig raising was originally a sideline on many Western Australian farms, being a convenient and profitable way to dispose of 'skim' milk on butterfat dairy farms and 'seconds' quality grain on wheat farms.

Most farmers ran pigs in large sties or small paddocks. With little capital tied up in buildings, it was easy to 'get out of pigs' when prices dropped, and get in again when prices improved. This led to a cyclic pattern, with pig numbers rising to a peak every three to four years then falling when low prices caused oversupply.

Dairy farmers in the south-west usually kept …

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.

Fisheries Report No. 81 - A Research Vessel Survey Of Pearl Oyster And Prawn Resources North-West Of Broome Western Australia, J. W. Penn, R. Dybdahl

Fisheries Research Reports

Data from a research vessel survey in September and October 1987 and commercial catch records have been used to assess the pearl oyster and prawn stocks along the Broome coastline between 17°S and 18°S latitudes. Observations made by pearl divers indicated that the survey zone contained commercially significant quantities of unfished pearl oysters particularly in the depth range 10 to 27 m, but also extending out to 44 m depth. The pearl oysters in the survey zone were found to be predominantly mature animals and appeared to be part of the now lightly fished deep water spawning population extending from …

The Offshore Constitutional Settlement Western Australia 1988, Fisheries Department Of Western Australia

Fisheries Management Papers

In June 1987 under the Offshore Constitution Settlement (OCS), the Australian and West Australian State Governments completed the first stage of rationalising jurisdiction over a number of fisheries operating off the West Australian coast.

Arrangements under the OCS for West Australian fisheries fall into three catagories:

1. fisheries managed by the State under State law as far seaward as the arrangement specifies.

2. fisheries managed by the West Australian Fisheries Joint Management Authority under State laws in waters were the arrangement applies.

3. fisheries managed by the Commonwealth under Commonwealth law in waters where the arrangement applies.

Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside

Animal production and livestock published reports

The role of the Rangeland Management Branch is to promote the sustained economic use of the rangeland resource. It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …

Fisheries Management Paper No. 15 - Draft Management Plan For The Control Of Barramundi Gillnet Fishing In The Kimberley., R. S. Brown

Fisheries Management Papers

This management plan sets out a number of options for the control of commercial gillnet fishing for barramundi in the Kimberley. the plan focuses on existing commercial fishery, and on the fishermen consulted during the process of developing these management arrangements. However, the barramundi stocks of the region are increasingly exploited by large numbers of both local and tourist recreational fishermen whose needs must also be catered for. Because recreational fishermen are not easily identified or contacted as a group, I have endeavoured in this foreword, to set out the management options which best take into account the future needs …

Economics And Marketing Of Western Australia Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

The 1986/87 Australian catch was about 8,300 tonnes. At present levels of fishing,it has been suggested that this could be substantially increased. The fishery is not in danger of over-exploitation. Rather, the problem could be that there is more fish available than existing markets could absorb. However, there are prospects for increasing the present volume of fish sold domestically and for developing new products and markets in Australia and overseas.

Draft Management Plan For The Perth Metropolitan Purse Seine Fishery, P. Millington

Fisheries Management Papers

As part of a development strategy for inshore purse seine fishing along the Western Australian coast this plan proposes management measures for the purse seine fishing boats operating along the coast near the greater Perth Metropolitan area. Using as a basis the restricted entry Cockburn sound purse seine fishery, the plan proposes the introduction of a limited entry regime for inshore purse seine fishing between Lancelin to just south of Mandurah. This regime will permit management of the available pelagic fish stocks in the area and also protect the economic position of the existing participants by providing an environment for …

Identification of the constraints and potential for industry development of these resources is made focusing on the area considered most favourable, types of vessels used, fishing methods and strategies required for the development of such resources in the event that there is some identified prospect of viable commercial development.

The South West Trawl Fishery Draft Management Plan., P. J. Millington

Fisheries Management Papers

This paper outlines a proposal for management of trawl fisheries operating in waters less than 200m deep between the Moore River north of Perth and Cape Leeuwin. Off Fremantle, potential and actual user conflicts between trawling and the requirements of recreational fishing and other forms of commercial fishing point to the need to gradually phase out trawling in this area. A limited entry fishery, with no licence transferability, is therefore proposed.

Sport Fishing For Marron In Western Australia - Management For The Future : A Discussion Paper On Management Options For The Marron Fishery., Fisheries Department Of Western Australia.

Fisheries Management Papers

The number of marron that may be caught each year without seriously jeopardising the long term future of fishery is limited. The situation deteriorated still further after another winter of low rainfall in 1987 and as the 1987-88 summer drew closer it became doubtful whether the State's marron stocks could withstand another season of hard fishing pressure. Thus, it was considered necessary to ban all fishing for marron during the 1987-88 season. This discussion paper has been prepared to help start the ball rolling in the right direction, and ensure any measures taken to safeguard the fishery are backed up …

Fisheries Management Paper No. 22 - Economics And Marketing Of Western Australian Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

Most of the Western Australian pilchard catch comes from King George Sound and from the southern coast off Albany where the number of vessels allowed to catch has been controlled. Prospects for increasing production in this area are limited. However, there are indications that considerable quantities of pilchards could be caught in waters to the east and west of Albany, in the inshore declared purse seine development zone.

Before allowing fisherman to catch more pilchards in these waters, the Western Australian Government decided that an investigation should be undertaken of the Australian pilchard resources, the domestic and export market situation …

New Initiatives In Processing Australian Sheep Skins, P G. Frapple

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

Australia's exports of 313 million preserved sheep and lamb skins were valued at $A261.2 million FOB (free on board) in 1986-87. Just over 40 per cent (13.1 million) of these skins went to France for fellmongering, which is the process of removing wool from skins, leaving a bare pelt suitable for tanning. The balance went to other countries including Yugoslavia, Spain and West Germany, mainly for tanning with the wool on.

Fox Attacks On Cashmere Goats, John L. Long, Peter Mawson, Peter Hubach, Neville Kok

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

Since the fox arrived in Western Australia from South Australia in the early 1900s it has preyed on our native animals and domestic livestock, traditionally lambs and poultry. With the establishment of a Cashmere goat industry in the State, the potential exists for the fox to become an even greater problem.
