and will eventually produce cows which are close to pure Limousin
- which will not give enough milk from an all forage diet for
well grown suckled calves.
Herefords
Introduced
This summer, some pure bred Hereford females and a bull were
introduced onto the farm. Some of the rougher grazing was not
being utilised by sheep and the Herefords will be used to improve
these areas. Initially the Herefords will be bred pure to build
up numbers but the intention then is to produce Hereford cross
replacements for the main herd on the lower land. The main concern
is the size of the finished cross Hereford stock but output
of finished beef per acre may remain similar if more, smaller
cows, can be kept.
Heifers have been kept longer than usual as there
was a surplus of grass over the summer and they continued to
gain weight. All the cattle have been marketed through Dovecote
Park to Waitrose.
During the monitoring of the Technical Development
Farm we should be able to compare the performance of progeny
from South Devon, South Devon x Limousin and Hereford cows.

onathan, Eileen and David
Williams have been farming organically for more than 10 years. The
organic system is now well established and the increasing fertility
continues to produce an excess of grass. The stocking rate is currently
under review and changes are already underway. This winter, the
suckler herd will increase from 60 to 70 head and the sheep flock
from 800 to 1,050 ewes. |

Breeding
Policy
The technical group meeting in August discussed future breeding
policy and was led by Dennis Chapple from ADAS Rosemaund. Organic
standards allow up to 10% of a herd to be replaced from a non-organic
source but the |
|
| preferred
system would produce all its own replacements. This gives a strong
argument for pure breeds. However, Dennis gave a figure of 25% for
the improvement in performance resulting from |
|
the hybrid
vigour of cross- bred cows. This is a strong argument against keeping
pure breeds!
At Cefn Llech, the herd is based on South Devon cows
which are crossed with a Limousin bull. In the past, pure bred South
Devon steers and surplus heifers were found to be slow to mature
and lacked conformation. Recently, some of the South Devon cross
Limousin heifers have entered the herd as replacements; these are
also crossed back to a Limousin. Obviously, this system is not
