Newsletter
for the week ending 7 January 2005
Welcome to 2005!
The
year has started much as 2004 ended. A buoyant cattle market and moderate
temperatures for summer with rain in some areas. I am optimistic that
2005 will be an even better year for Limousin than 2004.
New DNA Markers
Australian
company Genetic Solutions have announced the release of two new DNA markers for
marbling. This brings the suite of DNA markers offered by Genetic
Solutions to two tenderness and three marbling markers. The company
claims that the three marbling markers are additive and can be used to sort
cattle entering a feedlot program on their potential for marbling in a long fed
program. Those cattle with lower potential to marble would be fed for
shorter periods and different markets. The frequency of the two new
markers in Limousin has not yet been determined but is probably low.
All
new samples submitted to Genetic Solutions will be tested for the new
markers. Samples submitted for testing prior to 20 December 2004 can be
upgraded with the new markers for $20 plus GST.
The
release of these new markers reinforces the leading international role this
Australian company has in the development of Gene Marker technology.
The
recent announcement of $30m Federal Government funding for the Cooperative
Research Centre for Beef (CRC3) will see an increased research effort to
discover new gene markers in Australia.
Good Suggestions and Gripes
If
you have a good suggestion or a gripe which you would like to make to someone
other than staff at the ALBS office please feel free to contact one or more of
the nine Directors who make up the Board of the Society. Their phone
numbers are listed in each copy of Limousin Australia.
Two
good suggestions have come in from individual members in the last month.
The first was that the Society consider running a structured progeny test
program to identify superior Australian bred bulls for use by AI. The
program could be modeled on a program recently commenced by Angus Australia
which requires the identification of promising young bulls and the use of these
bulls by AI by other breeders to get accurate EBVs early in the bulls' lives.
This
proposal will be considered by the Board at their May 2005 meeting so please
talk to a Director if you like or dislike the idea.
Web Certificates
A
web oriented member has suggested that we should make Registration Certificates
available via the web for those breeders who would like to get their
certificates this way rather than by post. I am currently obtaining a
quotation for the implementation of this service and hope to have the option
available in the near future subject to Board approval.
Interpreting EBVs for Imported Sires
As
part of the Limousin genetic analysis the country of origin EBVs are
"imported" to the Australian analysis. These imported EBVs
convert to low accuracy Australian EBVs.
As
measurements on Australian born progeny are added to the analysis, the accuracy
of these EBVs increases. There is a considerable delay for this to happen
for milk EBVs because we have to wait until we get weaning weights on progeny
of daughters born in Australia.
In
the latest analysis some of the recently imported French sires have relatively
low EBVs for milk compared to their French Index (EBV) for milk which is based
on many daughters in production.
Where
there is a conflict my advice is to rely on the EBV (Index) based on the
greatest number of progeny or daughters - in this case the figures from France
or the UK.
We
do not import EPDs for docility from North America but there is a strong
correlation between the US EPDs and the Australian EBVs for docility.
However there is an occasional conflict. DJ Gentleman in Black is a point
in case in this analysis. His US EPD for docility is +22 but his
Australian EBV based on a small number of progeny is +1. I would be
inclined to place more emphasis on his US EPD at this stage.
Maitland NSW Sale Toppers
Limousin
member Jean Kelehear of Dungog sold 14 Limousin cross steer vealers at Maitland
Saleyards in late December. Weighing 381kg they averaged 222.7 c/kg or
$848.
The
top six steers sold for $870 and the lowest price was $817 in an outstanding
sale.
Mount Gambier SA Sale Toppers
From
the Stock Journal of 23 December.
"Cattle
prices peaked at Mount Gambier on Monday with TR & CM Little, Kongorong,
achieving $2.22/kg, averaging $939 a head, for nine outstanding heavy Limousin
cross vealer steers."
Denver Next Week
I
will be in Denver Colorado USA next week to meet with the Executive of the
International Limousin Council as part of the planning for the 2006 Conference
in Australia.
The
meeting coincides with the National Western Stock Show which I look forward to
attending. A feature of the Stock Show is the Pen and Carload
Competition. The pens of 3 bulls and carloads of 10 yearling bulls are
all housed outdoors (usually in the snow) before judging. Some of the US
sires currently being used in Australia were exhibited in the National Western
Pen and Carload Show.
Yours in Limousin
