Determination Of The Levels Of Zinc, Copper, Calcium, Phosphorus And Magnesium Of Chios Ewes In The Aydın Region, Funda Kargin, Kami̇l Seyrek, Ayşegül Bi̇ldi̇k, Serap Aypak

Turkish Journal of Veterinary & Animal Sciences

This study was undertaken to investigate the Cu, Zn, Ca, P and Mg levels of blood serum and the Cu and Zn levels of wool from clinically healthy Chios ewes grazed in meadows in the Aydın region. A total of 100 blood and wool samples from various villages in different districts of Aydın (Germencik, Yenipazar, Çine, Koçarlı and the central district) were studied. The Zn and Cu values were determined by an atomic absorption spectrophotometer. Serum Ca, P and Mg were measured by photometer using commercially available kits. The average Cu, Ca, P and Mg values of sera were near …

Turkish Journal of Veterinary & Animal Sciences

The aim of this study is to determine the copper, zinc and selenium levels of blood serum and the Cu and Zn levels of wool of healthy Akkaraman ewes grazed in the meadows in the Diyarbakır region. A total of 60 units of blood and wool samples from various villages in different counties of Diyarbakır (Bismil, Çınar, Ergani, Silvan, Kocaköy and some Diyarbakır villages) were studied. The Cu, Zn and Se levels of sera and the Cu and Zn levels of wool were analyzed by flameless atomic absorption spectrophotometer. We found significant differences in Cu and Se levels of sera, …

Ofda2000 Brings Major Changes For Wool Industry, Andrew Peterson

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

The classing of any wool clip into lines of uniform quality is a crucial step in optimising the value of the wool. Objective Clip Preparation (OCP) standards and training of wool classers lave led to the Australian wool clip being internationally recognised as the best classed and prepared wool in the world. However, adherence to OCP standards of clip preparation still leads to a substantial range in diameter and crimp frequency of fleeces within the main lines. Therefore, an opportunity has existed to develop improved technology to reduce the variation in quality within any main line, create lines of even …

Selling Western Australian Wool To The World, Georgina Wilson

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

Western Australia supplies 14 per cent of the worls's apparel wool and Agriculture WA's Wool Program has been working to raise the State's profile as a consistent supplier of high quality fibre to the world markets. It's a slow process in a very traditional industry, but modern measurement and computers are useful tools as Georgina Wilson explains.

Teasing Apart The Threads Of Staple Strength, Andrew Peterson

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

A successful partnership between two local inventors and Agriculture WA's Wool Program has created a new instrument which, just like the growth rings of trees, can show seasonal changes in the fibre diameter of wool. This will have considerable value to the wool industry as Andrew Peterson explains.

Today's Woolgrowers : A Profile, Ian Mcfarland

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

Woolgrowers have been faced with fluctuating prices, a mix of seasons and rising production costs since the demise of the Floor Price Scheme in 1991. despite these difficult times, there are still very large differences in productivity and profitability between wool growing properties in Western Australia. Ian McFarland looksat production levels on wool growing properties in Western Australia and outlines some actions to lift productivity.

A Measure Of Justice For Western Australian Wools, John Stanton

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

Western Australian wools are sometimes perceived as inferior to those from eastern States, and this perception has often been reflected in price. For the first time a detailed comparison of the characteristics of our wool with the rest of the country has been undertaken. It shows that Western Australian wools are sometimes different from their eastern counterparts, but not necessarily 'inferior'. Overcoming these industry perceptions of inferiority is probably our biggest challenge, according to JOHN STANTON.

Awassi Fat Tails : A Chance For Premium Exports, Fiona Sunderman, Michael Johns

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

Most prople have heard of the Awassi, even if they have never seen one. This unique breed of fat tail sheep, imported into Astralia in 1987, was released from quarantine for commercial development nearly 12 months ago. Its supporters believe Awassis could form the basis of a high-value export industry while replacing imports. Developments over the next few years will test its potential and should result in the Awassi playing an important role in an increasingly diversified Australian farming scene.

Careful Clip Preparation Will Increase Profit, Peter Metcalfe, Ric Collins

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

The current wool market has forced wool growers into producing the maximum number of kilograms of quality wool for the least cost. Preparation of the clip is now much more important to maximise possible net returns. Careful clip preparation will ensure that growers receive the maximum overall average price for each kilogram of wool in the clip.

How Arsenic Residues Get In Wool, Tony Martin, Robin Jacob, Marion Davies, Peter Rutherford

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

Wool can become contaminated with arsenic in various ways, and several different sources may each contribute to any individual arsenic residue problem.

• dipping sheep in an arsenical dip ( now illegal),

• dipping sheep in a non-arsenical dip in a contaminated dipping facility

• penning sheep on soil with high levels of arsenic before shearing.

Other possible sources include running sheep on land contaminated by gold mine tailings or exploration sites, and allowing sheep access to sites on the farm where arsenical compounds have been dumped, for example, rubbish dumps or sites where dip/sump sludge has been dumped.

Wool Staple Strength, I G. Ralph

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

The staple strength of western Australia's wool has come under scruitiny since additional wool measurements to those of yield, fibre diameter and vegetable matter began throughout the Australian 985-86 wool selling season.

In 1980, the Sale by Additional Measurement Trial conducted on the September-October wool sales at Fremantle showed a range in staple breaking forcesfrom 10 to 70 Newtons per kilotex, with an average breaking force of between 30 and 35 N/ktex, A third of the lots offered for sale had a staple breaking force of less than 26 N/ktex, a value which, according to the Australian Wool Testing Authority, …

Dispelling Some Myths About 'Dermo', J R. Edwards

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

There are a lot of misconceptions and myths about dermatophilosis, a disease which can kill young lambs, affect wool quality, make shearing difficult and make sheep susceptible to fly strike.

One misconception is perpetuated by the incorrect use of the name mycotic dermatitis, which implies that a fungus causes the disease. This is not so.

The disease is caused by the bacteria Dermatophilus congolensis, which attacks the sheep's skin and eventually forms a lesion or scab in the wool, and so is better called dermatophilosis, 'dermo' or 'lumpy wool'.

Veterinary Epidemiologist at the Albany Regional Office, J.R. Edwards, discusses …

Lumpy Wool May Increase By Dipping : Research Roundup, Department Of Agriculture, Western Australia

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

Lumpy wool, or mycotic dermatitis, is an infectious disease on the skin of the sheep caused by the bacterium Dermatophilus conglensis. The organism invades the wool and hair follicles, causing formation of skin lesions producing scabby material which binds the wool fibres into a hard mass.

Research shows that 'dipping' may increase the incidence of lumpy wool with some chemicals a greater risk than others.

Mycotic Dermatitis (Lumpy Wool) And Fleece Rot Of Sheep, J Shilkin

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

Matted and sometimes discoloured specimens of wool are often received at the Department of Agriculture during seasons of heavy rainfall.

Two similar but quite distinct diseases are recognised as having caused this condition.

They are mycotic dermatitis (lumpy wool) and fleece rot. Both conditions damage the fleece and render affected sheep susceptible to blowfly strike.
