Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …

Worm Control In Sheep In Western Australia. Crack Down On Worms: An Information Guide For Advisers, Consultants, Livestock Personnel And Farmers, Department Of Agriculture, Western Australia

Animal production and livestock published reports

In Western Australia’s winter rainfall areas, the control of gastro-intestinal sheep worms is based on the strategic timing of drenches.

Sheep are drenched at a time that reduces the contamination of pastures with worm eggs and larvae in late summer and autumn. The timing of the drenches is particularly important for the control ofbrown stomach worms (Ostertagia species) and black scour worms (Trichostrongylus species)

Drenches given in late spring, when pasture is starting to dry off, and again in summer, successfully reduce pasture contamination in mid summer and autumn. A faecal egg count will determine the need and timing of …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob

Animal production and livestock published reports

Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).

Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.

Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …

Miscellaneous Publication 39/91 - How To Eradicate Virulent Footrot From Your Property. A Farmer's Guide., Dianne Hopkins

Animal production and livestock published reports

The first thing to understand about virulent footrot is that it can occur on any farm in the medium to high rainfall zone.

People often associate footrot with properties managed by inefficient farmers. This is a belief based on fallacy. Many good farmers have found the disease in their sheep, including high profile stud producers.

Footrot can strike anywhere and without warning.

The important thing to remember is, that once it is found, getting to know the disease and understanding it will help you beat it. This manual, the video and your stock inspector will help you eradicate footrot from …

Bulletin 4152 - Sheep In Western Australia, R J. Suiter

Bulletins 4000 -

Western Australia's sheep industry started in the early 1830s when the first flock-owners grazed their sheep on extensive areas of native vegetation, often by shepherding on unfenced country. Later, farm flocks built up as settlers cleared and fenced land for cultivation, and 'pastoral' or 'station' sheep were confined to fenced areas of native vegetation, leased from the Government.

By 1900, more than 75 per cent of Western Australia's sheep were still classed as 'pastoral', but by 1987/88, the pastoral areas carried only 2 million of the 34.1 million State flock.

Today, many former sheep stations carry cattle, which survive better …

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 …

Grain and other field crops research reports

In the past couple of years research into lupins has increased substantially particularly in the fields of weed control, seeding rates, and control of diseases such as brown leaf spot and pleiochaeta root rot. This report is a summary of the lupin trials in the Lake Grace advisory area as well as a guide to better lupin farming.

Bulletin Ma 20 - Sheep Yard Plans - Flocks Up To 500, D. Bicknell

Animal production and livestock published reports

Manjimup Regional Office

Owners of small flocks often use much more labour per sheep than do owners of large flocks. Most of the difference in labour use is the design of sheep sheds and sheep yards, and a smaller affect from the mob size and experience in handling sheep.

This booklet gives some detail on design and construction of yards and a number of yard plans to handle up to 500 or so sheep. Many of the plans are from an Australian Wool Corporation publicatiot1 "Wool Harvesting Notes".

Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin

Bulletins - 3000 - 3999

This article deals with those native, naturalized and cultivated plants, which by virtue of contained cyanogenetic glycosides, are known to be poisonous or potentially poisonous to livestock in Western Australia.

Cyanogenetic glycosides are chemical compounds which contain a cyanogen (cyanide) radical combined with a sugar molecule. The sugar moiety may differ in glycosides obtained from different plants, and as a consequence glycosides from different plants, containing different sugar moieties, may be given different names.

When a cyanogenetic glycoside is broken down by enzyme action, through injury to the plant or by microbial action in the digestive system of the animal, …

Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson

Bulletins - 3000 - 3999

Vitamin A is one of the essential vitamins for animal health. Grazing animals obtain their vitamin A requirements mostly from the carotene in green feed. This carotene is converted to Vitamin A in the intestinal wall and is passed to the liver and to a less extent the kidneys for storage. Some carotene also passes direct to the liver where it is stored before it is converted to vitamin A.

When dry pastures, hay and grains (except maize) are low in carotene content this ability of the animals to store vitamin A means that they usually have enough when there …

Partial Budgeting For Sheep Farmers, J W. Malcolm

Farm Systems and Economics published reports

A Programmed Text.

A Programmed instruction workbook.

*The first 11 pages are adapted from J.B. Bardsley's "How to make more profit on dairy farms".

This book is designed to show you how to draw up partial budgets.

If you are like most farmers you are probably searching for different ways of running your farm to increase farm income. Choices between alternatives are very difficult, and require a great deal of careful thought and planning, especially where large cash outlays are involved. But to decide how, where and what to produce with any confidence you need to consider all the physical …

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …
