SHEEP BREEDING AT CANNON
The breeding flock at Cannon is made up of fully recorded Hardy,
Welsh Hill Speckle Face sheep.

The breed originated in the hills of Mid-Wales and is believed
to have been derived from the crossing of Kerry Hill sheep and Welsh Mountain
sheep. The breed became uniform with the establishment of the Breed Society
in 1969.
The natural habitat of the breed is the uplands
of Mid and North Wales. The winters in these areas can be tough
and a high annual rainfall.
As part of an ongoing effort to continually improve
the flock at Cannon we record every sheep as part of a Sire Reference
Scheme. This involves recording the sire and dam of each lamb
born. The lambs are then weighed at 8 weeks of age to get an indication
of the maternal traits of its parents, and then weighed and an
ultrasonic scan taken of it's loin area at 21 weeks. This gives
an indication of it's genetic merit, and, when sires are recorded
across a number of flocks it gives an indication of the value
of the sire and dam.
Although recording a large number of ewes does require
a great commitment and effort, the results more than justify the
investment in a greater value carcass and increased value of breeding
stock.
To help with the record keeping each sheep has an
electronic tag or bolus. This can be read be a hand held reader
that identifies the animal and can record tasks. This has speeded
up the recording process and removed many of the errors made when
recording with a pen and paper.
One of the greatest challenges to a sheep is another
sheep. This is because they all shed ineffective internal parasites,
or worms. Until recently conventional farmers could control these
internal parasites with chemical drenches, but due to their over
use and incorrect use, there is an increasing incidence of worms
becoming resistant to the chemicals in the drenches. Organic farmers,of
course, have never relied on the prophylactic use of chemical
wormers but have had to rely on management skills such as rotational
grazing or mixed grazing. At Cannon we have been monitoring the
faecal egg output of our stock and selecting breeding replacements
only from animals showing a genetic resistance to worms. These
sheep will not only be of high value to organic farmers but also
to the conventional sector as intestinal worms become increasingly
resistant to chemical drenches.
