Question from Gerrie
Du Preez (HI 5/2006);
In your opinion do you think there will be
demand for cross-bred bulls in the near future?
Winkels: ‘There may be some, but there shouldn’t
be. It is well documented that there are many Holstein bulls
that can give dairymen better results in the areas of calving
ease, somatic cell, and productive life than the bulls
currently being promoted for crossbreeding. We simply haven’t
been selecting for these traits; only for production traits. We
now need
to do a slight correction, but let’s not throw the baby out with
the bathwater.’
2.
Do you see
in-breeding as the cause
of the Holsteins reproductive problems?
‘Inbreeding
definitely lowers fertility in all plants and animals. The
bigger problem in the United States is that we have been
intensely inbreeding to bulls that are poor for fertility
traits. I am totally shocked that here in America we have
inbred so heavily to the Bell bloodlines. Mating of full, ¾,
etc. brothers and sisters to each other are routine and highly
praised. There is a reason that within the human race that we
do not marry our sisters or cousins. Sometimes when everyone
is going to the left it is a smart idea to go right and that is
what we have done bringing in very limited amounts of Bell blood
in our young sire program for a number of years. We feel that
especially in the United States there is going to be a real need
for outcross blood lines in the near if not immediate future.’
3.
Would you be
in favour of a system similar to the one in
New Zealand where all breeds are put on a common base?
‘I don’t know anything about the New Zealand system, but I do
know that all bulls from all countries should get a fair
comparison.’
4.
What’s driving
the current wave of interest in cross-breeding?
‘Simply
put, MONEY. There are a few individuals that are making a large
profit by importing, promoting, and selling semen for
crossbreeding. There are supposedly 3 Montbeliarde bulls that
are +3000 lbs of milk and several others +2000 lbs of milk with
semen available. In the US we have no genetic base for the
Scandinavian Red breeds, so the USDA figures their converted
proofs on an Ayrshire base. The Ayrshire breed runs about a
15,000 lb. average while the Holsteins runs a 24,000 lb.
average. Many of these bulls end up having proofs of over +1500
lbs. of milk, and that’s entirely misleading. It’s like saying
that a 17 year old boy on the Rochester High School Soccer Team
that scores 100 goals per year is going to score 100 goals per
year playing for the Brazilian National team. It just isn’t
going to happen.
When a commercial
dairyman with limited knowledge of genetics is offered semen
from a bull that will give him hybrid vigor, calving ease, high
productive life, and is SUPPOSEDLY +1500 to + 3000 lbs of milk
he is going to buy it. If these bulls have their proofs
computed on realistic terms showing their true values for
production and type the interest in cross breeding will
completely cease to exist, at least on any wide spread basis, in
less than 6 months in the United States.’
5.
Have you seen
good acceptance in
America of bulls proven in other countries?
‘We
do have good acceptance now, and they should be because they
really are all the same bloodlines anyway. Changing from ½ cc to
¼ cc straws is the real challenge we face. To make it worse all
semen is still handled on canes which is really outdated
technology. Herds of over 2000 cows are common in the US and
they need multiple tanks to store their semen. If canes were
eliminated and goblets used, semen handling would be simpler and
settling rates would go up.’
6.
Do American
breeders still have questions
about the accuracy of proofs from other countries?
‘We saw quite a bit of that in the past, but the systems are
much more accurate now and breeders accept them better.’
7.
What does
America have to do to retain its
leadership position in the Holstein industry?
‘We need to realize that we are not the centre of the Holstein
universe as we once were. Other countries see genetics from a
global perspective, and use the best bulls from all countries.
And we need to do the same.’
8.
What traits do
you emphasize when selecting young sires?
‘We select bulls that will correct the faults in the general cow
population. We have intentionally selected young bulls that will
sire strength, width, power, and substance of bone, because cows
today all over the world have become weak, narrow, and frail.’
9.
Do you use set
index criteria when selecting bulls?
‘Yes,
a young sire’s Momma has to pass the “mouth watering test.” If
she doesn’t make my mouth water when I look at her, no son will
enter our program. This is a true statement, however we are
realists. If a young sire does not have a reasonable plus index
for type and production there is no point in sampling him as he
will have no chance of having a marketable proof. My wife and I
have 4 young children; we have to split up whatever money that
comes in every month between caring for our children and feeding
the bulls. A person who has to pay the board bill out of their
own pocket has a completely different outlook when selecting
young sires.’
10.
What question
would you like to ask our
next guest, the Irish breeder Paul Flanagan?
‘Are there any Holstein bulls named after famous Irish Soccer
Players? If not, which soccer player would you like to have a
bull named after?’
