Wool harvesting
Check list for efficient wool harvesting procedures and effective communication pathways at shearing:
- Set up effective communication with the contractor, shearers and shed staff
- Brief the team so they understand your expected standards
- Engage a shearing team known for the quality and reliability of its work and that employs sufficient shedhands
- Give particular attention to the level of shed staffing for sheep handling and wool preparation
- Read and apply the Grower Responsibilities section of the AWEX Code of Practice for Woolclassers
- Provide a better-than-average working environment; ensure that the shearing shed, as a minimum, meets your state’s Occupational Health and Safety (OH&S) requirements
- Acknowledge the professionalism of shearers and shed staff; this creates a highly productive and efficient work environment.
Consider the following in the annual stock management calendar:
- Choose a date for shearing that is likely to maximise the potential value of the total clip, in terms of both fibre characteristics (eg, staple strength, position of break) and total wool production
- Crutch within 3 months of the scheduled shearing date to reduce potential stained fibre contamination
- Manage the flock to ensure the sheep are kept dry, not scouring and not stressed by excessive yarding and handling immediately prior to shearing.
Wool preparation and classing the clip
Wool offered for sale in Australia is usually prepared by a suitably qualified and registered woolclasser. To be registered with AWEX a woolclasser must have completed and passed a recognised training course in woolclassing/wool preparation.
In preparation for shearing,
- Provide the classer with a breakdown (preferably written) of flock structure with regard to mob sizes, ages and the order that they will be presented for shearing
- Provide the classer with previous years’ clip results
- Consult with the classer on the preparation of the clip prior to shearing
- Agree on the code of practice, particularly in determining the number of lines, observance of bale weight limits (195 kg is recommended, 204 kg is maximum) and guidelines for describing the wool in each bale.
- For the classer’s stencil to be applied to the bale of classed wool, the classer must adhere to the industry benchmark for wool clip preparation, the AWEX Code of Practice for Woolclassers.
- In smaller shearing sheds (four stands or less), the classer may assist wool handlers with clip preparation but in larger sheds the classer must concentrate wholly on classing and shed management.
- Visit your woolbroker’s showroom floor to inspect sample boxes and discuss your own clip’s preparation, test results and presentation. Ask about lot valuations and types. Take the time to inspect the classing and preparation of other clips of similar wool types from comparable regions.
- Actively seek and obtain feedback on the lots that sold well or below expectations or valuation. Enquire how the buyers typed and valued your clip. Keep a record of who buys your wool and where it might go for processing.
Further sources of information
The following sources provide information on best practice for shearing, wool preparation and classing.
Shearing Shed Guidelines – AWI provides guidance on planning new shearing sheds or renovating old sheds. Access the AWI home page (www.wool.com) and click on ‘People’, then select ‘shearing sheds and sheep yards’ from the menu.
The guidelines will help you improve productivity in the shearing shed and meet OH&S standards. From the same menu, you can gain some indication of the potential costs if these standards are not met, by selecting ‘shearing and OH&S’.
AWI Wool Handling and Shed Skills DVD – A Training DVD for wool handlers covering throwing, skirting, rolling and other shed responsibilities. To order your free DVD, call the AWI helpline on 1800 070 099 (free call within Australia).
The AWEX Code of Practice grower responsibilities – AWEX home page (www.awex.com.au) click on ‘wool classer’ and scroll down to code of practice. You can download the ‘grower responsibilities’ section of the code of practice from the website, or contact AWEX (02) 9428 6136 for a copy of the complete code of practice.
The code of practice provides guidance to wool classers on the standards required by customers of Australian wool. If your registered wool classer follows the Code you can be assured that:
- The processor will receive lines that are uniform in terms of visible characteristics
- There is minimum risk of contamination
- The documentation is accurate
On Farm Fibre Measurement (OFFM) – Search the web for "OFFM testing" or "fleecescan"to find commercial contractors, or to download a contractor list, click here.
OFFM is a valuable tool in accelerated breeding from superior animals (see tool 9.10 in Gain from Genetics) and culling of low-value animals. In addition, there are occasions when producers of superfine wool (below 18 micron) have found OFFM helpful in compiling homogenous sale lines of finer wools if OFFM quality assurance guidelines are followed. Ensure that the potential fibre diameter premiums outweigh the likely additional costs.
Analysing a typical wool clip over five years (2000-2005), OFFM can return per sheep net profits* of between $3.04 (20 micron flock) and $5.56 (18 micron flock), primarily by improved selection and breeding. (*Source: OFFM Calculator).
The OFFM Calculator was developed by Dr Kevin Atkins and Steve Semple from NSW Department of Primary Industries with funding from AWI, the Australian Sheep Industry CRC, and the International Fibre Centre.
