Studies On Times Of Lambing In Ewes Grazing Subterranean Clover Based Pastures In Relation To Stocking Rates In South-Western Australia, H Lloyd Davies
Studies On Times Of Lambing In Ewes Grazing Subterranean Clover Based Pastures In Relation To Stocking Rates In South-Western Australia, H Lloyd Davies
Technical Bulletins
The investigation is reported in six parts: effect on ewe liveweight and fertility, lamb losses, effect on lamb growth and subsequent growth after weaning, wool production, pasture production and composition, and conclusions and practical implications. The results show that in the absence of supplementary feeding the physiological requirements of ewes in late pregnancy are better met by spring rather than autumn lambing.

Trial 84V2.
Location: Vasse Research Station
Aims: To define seasonal pasture production curves for three rainfall zones in Western Australia. To determine animal productivity under different production systems in response to seasonal pasture production. To provide Western Australian data useful for validation of sheep simulation models. To provide data for different production systems to increase the scope of the simulation models.

Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Journal of the Department of Agriculture, Western Australia, Series 4
The humble woodchip, widwly used as a soil mulch in Western Australian gardens, is set tto take a new role as a dust inhibito in assembly yards used to hold live sheep for export.
Research by the Department of Agriculture's Soil Conservation Service Branch has shown that, of the materials tested, woodchips were the most effective in preventing dust being generated. Wind speeds had to approach a "near gale" before dust developedfrom the protected soil.
The use of woodchips, therefore, provides a practical alternative to stabalising the soil and preventing an environmental problem associated with one of the State's valuable …
Sheep Lice : Prospects For Eradication, F C. Wilkinson
Sheep Lice : Prospects For Eradication, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
Sheep biting lice have been controlled over the past 86 years in Western australia by a combination of routine insecticidal treatment after shearing and action by the department of Agriculture officers under legislation.
In July 1987 the sheep industry and the State Government will implement a plan to eradicate lice from sheep flocks in the agricultural areas and eventually in the pastoral areas. To achieve this the co-operation of many sectors of the industry will be required. Assuming co-operation is forthcoming, it is possible that by 1996 wool from agricultural areas will be free of lice and insecticidal treatment form …
Analysing Feeds For Cattle, Sheep And Goats, D J. Barker
Analysing Feeds For Cattle, Sheep And Goats, D J. Barker
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture's Feed Evaluation Unit at Bunbury provides a service for farmers and allied industries on a fee-for-service basis, and conducts analyses for research officers, advisers and organisations such as the University ofWestern Australia. It also analyses feedstuffs for Departments of Agriculture in other States.
The Unit analyses about 5000 samples each year. The work load is high because no other laboratory in Western Australia provides the same service. Results are recorded on a computer which makes it easy t6o retrieve results of analyses of particular types of feedstuffs or froma particular owner or district.
Survival Of Lambs, R W. Kelly, David Lindsay
Survival Of Lambs, R W. Kelly, David Lindsay
Journal of the Department of Agriculture, Western Australia, Series 4
Between one in every five or six lambs that are born each year in Western Australia die at or about the time of birth. This represents a loss approaching two million lambs and is arguably out single greatest wastage in sheep production. The deaths have an immediate impact on lambing performance and therefore lamb sales, and ultimately effects on such areas as selection of breeding replacement stock, the proportion of ewes and weathers that can be run in a self-replacing flock and the amount of wool produced and its uality.
This article summarises information on what influences lamb survival, and …
The Awassi Fat Tail Sheep Project, R J. Lightfoot
The Awassi Fat Tail Sheep Project, R J. Lightfoot
Journal of the Department of Agriculture, Western Australia, Series 4
Australia's first Awassi fat tail lambs arrived at Kununurra in January 1987, completing the first major step in an ambitious project to establish a fat tail sheep breeding industry in this country.
Fat tail sheep bred in the Middle East attract much higher prices than merino wethers imported from Australia. The question to be resolved through our product development and market research is what premiums will Middle Eastern buyers pay for fat tail sheep bred in Australia and exported to the region.
The Department of Agriculture believes that there is potential for Sustralian producers to enter these new markets without …
Live Sheep Exports : Market Update, E J. O'Loughlin
Live Sheep Exports : Market Update, E J. O'Loughlin
Journal of the Department of Agriculture, Western Australia, Series 4
The live sheep export trade has made an important contribution to the Western Australian sheep industry, with the value of exports peaking at $100 million f.o.b. in 1980-81. In that year Western Australia accounted for 61 per cent of the value of Australian exports of live sheep. In addition, the growth of the live export industry has contribuited to higher prices for other catagories of sheep than would otherwise have been the case.
Feeding Behaviour Of Live Sheep During Export, C L. Mcdonald
Feeding Behaviour Of Live Sheep During Export, C L. Mcdonald
Journal of the Department of Agriculture, Western Australia, Series 4
Live sheep exporters in Western Australia often hold as many as 00 000 sheep in assembly feedlots while the consignment is being purchased and assembled before shipment. During the assembly phase the sheep ane introduced to the pelleted rations used on board.
Industry reports have highlighted the wide variability in condidtions, facilities and procedures used, and showed that there was little evidence from which to make recommendations to the live sheep shipping indudtry. This article discusses ten experiments by the Department of Agriculture from 1981 to 1985 designed to investigate what influences the feeding behaviour of Merino wethers under conditions …
Barber's Pole Worm : A New Solution, R B. Besier
Barber's Pole Worm : A New Solution, R B. Besier
Journal of the Department of Agriculture, Western Australia, Series 4
Barber's pole worm (Haemonchus contortus) has been a major problem to the sheep industry for many years. About ten million sheep graze in Western Australia's high rainfall areas where barber's pole worm is prevalent, and the annual cost of losses and control totals millions of dollars each year.
Research in progress in Albany now offers the prospect of prolomged and reliable control of barber's pole worm, by means of few drench treatments.
