SELECTIONS - Winter 2004
Herdlife Builder™ Program is Right on Target
By David Thorbahn, general manager and executive vice president
In my travels as a sire analyst in years past, some of the world’s leading producers shared with me that
cows need strength to last. Geneticists have said
research shows that strength has little value. I recently
attended the National Dairy Genetics Workshop,
held in October, to review the latest research and to
salute one the producer’s best friends in identifying
the truth, Dr. Ben McDaniel, North Carolina State
University, Raleigh, N.C. At that workshop the
research was pretty clear. Cows that milk at high
levels and hold their body condition are less
susceptible to disease, were healthier cattle and bred
back sooner than their counter parts with lower
body-condition scores. I am pretty sure this is what
my friends, the top breeders, were referring to when
they said cows need strength to last. If I saw them
today, they may answer me like the "Now Generation"
of my nieces and nephews, saying, "Well, duh."
Yes, what dairy producers have told us for years is
now being identified, though it is not in the form we
expected. The problem may be that we have either
been looking at strength and measuring the trait
incorrectly or we may have just been using the wrong
trait to identify constitution. We have learned that body
condition score or body constitution is more
accurately identified through the dairy form trait. Cows
with high dairy form are cows that can lose their
condition, are generally more susceptible to disease
and have the potential to be less reproductively sound.
True, dairy form scores are correlated by high
production, but we have PTAs for milk, fat and protein
to identify high production.
It would behoove the breeding industry to collect
body condition scores to find a more accurate
relationship between better reproduction and less
disease. In the mean time, I would suggest the following:
- For production, use PTAs for milk, fat and protein.
- Make udders and feet and legs an important part of
your breeding program.
- In addition to Somatic Cell Score and Productive Life,
include putting emphasis on moderate dairy-form bulls.
Or, for a simpler solution, use sires that are
Herdlife Builders.
I am pleased to inform you that the above
recommendations were incorporated into our Herdlife
Builder program at its inception. So if you have been
choosing Herdlife Builder sires, you are again ahead
of the game. The Herdlife Builder program identifies
bulls that are leaders in type traits associated with
"building" cows that last longer than their counter parts.
Select has always been a leader in designing cows that
last and our producer-customer sire committees will
force us, with good reason, to maintain this focus. The
Herdlife Builder designation is one more way for
producers to make breeding choices that will positively
influence the longevity of their cows.
To all the breeders who shared their insight with me
(and you know who you are), you were right once again -
listening to your customer really does pay off!
