British Simmental bulls improve milk
while still boosting growth and muscle
Significant improvements in growth and muscle depth – without
adversely affecting milking ability – are being been achieved
by the British Simmental, according to the latest figures from
Signet.
Signet beef specialist Alison Nicol says the British Simmental
is winning the ultimate challenge of any beef breed and is maintaining
its strong maternal traits while continuing to make sustained progress
on its beefing qualities.
“
Growth and milk traits are negatively correlated so even though
British Simmental breeders have put much emphasis in recent years
in selecting for improved beefing characteristics, the improvements
have been achieved with no loss of maternal values.
“
The British Simmental is now a heavier and more well-muscled breed
than it was 20 years ago but it remains genetically strong on milking
ability.
“
Breeders have been very careful in their breeding plans and have
protected milking ability. No milk has been lost along the road
of beef trait improvement – and that’s very important
to those suckled calf producers who are looking to the British
Simmental to produce herd replacements,“ says Alison Nicol.
She adds that the more emphasis beef cattle breeders place on the
selection of pedigree stock for growth and muscling the more likely
they are to put milking ability at risk – but the British
Simmental has not only held on to its well-proven milk traits but
has even shown some improvement.
BLUP figures produced by Signet show that the British Simmental
is now 30kg heavier at 400-days compared with 20 years ago and
it’s giving more milk.
Alison Nicol says there are many examples of BLUP recorded British
Simmental bulls showing very good growth and muscle scores while
still maintaining a high ranking on milk and calving ease.
“
Many more British Simmental bulls are now available showing high
scores for growth and muscle while continuing to provide suckled
calf producers with the opportunity to capitalise on the breed’s
sustained milking and maternal traits that are essential when breeding
home-bred herd replacements.
“
And as we move into the bull buying season it’s important
to remember that that while shape and weight are tangible traits
that can be assessed prior to purchase the only thing a buyer can
turn to for guidance on the bull’s maternal genetic make-up
are the BLUP performance figures – milking ability and calving
ease are not traits that can be evaluated visually” says
Alison Nicol.
