SHEARING PREPARATION - GENERAL
By Linda Wendelboe
- Plan well to reduce stress to the sheep and the people!
- Plan for breaks for refreshments at the convenience of the shearer.
If shearing all day, make sure a nourishing meal will be available (for the
people!).
- Plan to have a sufficient number of helpers to move and prepare sheep, weigh, sort and
skirt fibre and record information. If shearing a small number of sheep with
no time constraints, two or three people can manage all the jobs. If using the
services of a professional shearer to shear a large number of sheep, it is
useful to have enough helpers so that the shearer is not kept waiting.
- If shearing in hot weather, make sure everyone, people and sheep, will
have access to shade and
lots of liquids.
- Make sure newly shorn sheep will have access to shelter from bright sun
(especially important for white animals) or from inclement weather for at
least several days after shearing.
SHEARING PREPARATION – ANIMALS:
- Move sheep onto clean pastures free of brush, debris, dusty or muddy areas
and other fleece contaminants such as polypropylene twine, for several
weeks prior to shearing date, if possible. Avoid supplementary feeding from
above the sheep as this increases the debris in the fleeces.
- Fleece must be dry for best results so keep animals under cover if snow,
rain or heavy dew is likely, for several days prior to shearing date.
- Do not feed sheep for 12 - 24 hours before shearing. A "full"
sheep is harder to shear and more uncomfortable than a hungry one.
- Clean as much dust and debris from the fleece as possible just before
shearing by:
- Hand picking as much debris as possible.
- Sweeping gently across the fleece with a narrow, short handled leaf
rake. This can be done prior to blowing or vacuuming the animals to remove
the worst of the surface contamination or just on its own.
- *Blowing across fleece with a livestock blower (Circuiteer, etc.),
leaf blower or shop vacuum. Do not blow directly at or into the fleece as
this may push debris deeper into the fleece instead of removing it.
- *Combing or flicking contaminated locks with dog brush or comb.
- *Vacuuming with a shop vac.
*These methods tend to temporarily remove crimp and change the structure of
the staples/locks. They vary in effectiveness, depending on the levels of
contamination and the fleece type of the Shetland. If the fleece if to be
hand processed and hand spun after shearing or is to be entered in a fleece
competition, hand picking is preferable even though more labor intensive.
Blowing or vacuuming a Shetland before shearing can reduce the weight loss
experienced in processing. A "dirty" fleece weighs more than a blown fleece
containing an equal amount of fibre.
- Decide shearing order for the sheep before hand to ensure the right
animals are ready for shearing at the appropriate time. If you have current
histograms, the shearing order can be worked out based on this information.
- Plan to shear in an order that will prevent color contamination, ideally
moving from light to dark.
- If shearing a number of sheep of each colour, plan shearing order based on
fibre characteristics as well as on colour – for example shear fine whites
before coarse whites before moving to the next colour.
- If shearing rams, shear either before or after all of the ewes to avoid
stress.
- Ewes can be shorn at any stage in pregnancy but if shearing in the last
month of pregnancy, plan extra time for handling these sheep so they can be
restrained and moved gently to reduce stress as far as possible.
- If shearing more than one species, finish shearing one before starting on
the other.
Any contamination - whether vegetation, insect infestations, dirt,
polypropylene, other
foreign material, or different quality fibres - has an impact on the value of
the fleece and so should be reduced as far as possible. The amount of
contamination that is acceptable may vary depending on the end use of the
fleece. For example, fleeces going to commercial mills may contain some
vegetable matter without having an adverse affect on the quality of end product
but any polypropylene will be more troublesome, as it can not be
removed and will cause a problem in the finished product.
SHEARING PREPARATION - SURROUNDING AREA:
- The shearing area should be large enough to accommodate several people and
the sheep to be shorn, at the same time. Shearing under shelter is advisable
to prevent problems with contamination, snow, rain and wind.
- If a chute is to be used, make sure it is placed to allow the shearer easy
access without crowding walls or other building or fence features.
- Remove all sources of contamination from the shearing area and the areas
used to prepare sheep or sort fleeces. Contamination may come from:
polypropylene feed bags or twine, hay or other food sources, straw or other
bedding materials, mice, manure, gravel, sand, small objects of any type, food
wrappers, scrap paper, cigarette butts, other animal or man made fibre.
- Make sure there are adequate lighting, electrical outlets and ventilation.
- The flooring in the shearing area should be easy to keep free of
contamination but not slippery as that may cause either sheep or people to
fall. A large sheet of plywood may be placed on the ground or floor to provide
an appropriate surface. Old gym mats can also be used.
- Remove or pad any protrusions or sharp objects to prevent injury to either
sheep or people.
- Organize an area close to the shearing area to use for weighing, skirting
and sorting the fleece and recording information.
- Organize an area close to the shearing area for preparing and holding
sheep prior to shearing. This area should be large enough so sheep will not be
crowded, provoked into climbing on each other or subject to additional
stresses.
- Organize an area close to the shearing area to hold newly shorn sheep.
These sheep will need shelter from bright sun or inclement weather until they
get some fleece regrowth for protection. Several days are usually sufficient.
- Plan the routes for getting sheep from one area to the others.
