Unique: global overview of availabl

reeding a genetically polled and also genetically attractive Holstein herd is no longer a matter of dedicated pioneering. Lately
the international offering of young polled bulls with promising pedigree
indexes has grown fast. With ET and now DNA tests, breeding programs
have had effective tools over the past few years. Via intensive combination and selection, AIs integrate polled potential with the very best
Holstein and Red Holstein bloodlines. There are two kinds of genetically
polled bulls. With a heterozygous polled bull, indicated as pP, the combination with conventional horned Holsteins produces 50% offspring
without horns (Pp) and an equal number with horns (pp). A small
portion of the available polled bulls is homozygote (PP). When used
on conventional Holsteins, all offspring are born polled. The HI editors
LAWN BOY
In 2007, Aggravation Lawn Boy P-Red made it clear as America’s Nr. 1
Red Holstein bull that the polled gene is no limitation for trendsetting
production, type and fitness qualities. Lawn Boy is not listed among the
5 daughter-proven polled bulls in our table because the bull is dead
and there is no semen left. His name does frequently surface in the
pedigrees of young polled RC and Red Holstein bulls. Thanks to Lawn
Boy, polled genetics has gained in impact; the market for polled bulls is
about to break away from its niche status. ‘We have a number of polled
bulls available. They are more popular than last year, even though the
number of sold units of semen in Hessen only rose from 1 to 2.2%.
Nevertheless, we are investing considerable energy into our breeding
program to get interesting polled bulls. Creating new families, preferably homozygous polled, offers the opportunity to introduce the polled
gene into the population at large. In the future the market will become
larger if we succeed in offering the right bulls. The Lawn Boy son Laron
P, for instance, was our top selling DNA-tested Red Holstein bull in
2011,’ says Dr. Jens Baltissen, director of the German breeding program
ZBH. In the list there are many young German polled RC and Red Hol-

stein bulls. ‘About 5 to 10% of the young Holstein
bulls we sell from now on, are polled,’ comments
Hartwig Meinikmann, sire analyst for RUW. With
Lyon P-Red, his breeding program has one of the
rare daughter-proven polled bulls. ‘At the moment
polled bulls make up 3% of total semen sales at
RUW. In the future we expect a bigger percentage
because of increased political pressure to ban dehorning of calves. In addition, polled is something
new for dairy farmers and has the potential to
create new markets.’
SPECIAL FOCUS
In the replies from AIs to the question of how
future demand for polled bulls will develop, there
are two important criteria: political decision-making, and genetic quality as compared to the top of
the Holstein population. ‘We think that the genetic
level will dictate the popularity of these bulls. If
strong genetic lines are developed, then polled
bulls certainly will become more prevalent in
the industry,’ says Semex staff member Joan Lau.
Peter Thurn of Genetics Australia states: ‘We do
not have any polled Holsteins at present. Polled
bulls are starting to attract some attention in the
market, but at this moment it is not that important. I think with more and more focus on animal
welfare issues, calf dehorning will eventually be
put in the spotlight. Having a battery of highquality polled sires will be an advantage. We are
currently searching for the right polled genetics to
work into our program. It is not a short-term project and might take 2 to 3 generations before we
breed bulls of sufficient genetic quality to market.
Genomics may certainly speed up the process.’
Long-term projects have the clear goal of generating polled bulls in the top echelons of the bull
rankings; there is considerable ambition in the
words of several sire analysts and spokespeople.
‘We are aggressively trying to pursue polled opportunities to expand our Genesis program,’ says
Jennifer DeMunck of Genex CRI. ‘Polled genetics
have a structural place in our breeding program.
Each year we want to introduce a number of
homozygous as well a heterozygous polled bulls
to the market,’ explains Bertil Muller of CRV. ‘The
polled factor is very important in our breeding program. Especially to prepare for the future, we are
looking forward to heterozygous bulls with a high
total index. On a regular basis we will also have a
homozygous bull with a high total index available.
We have to continue to work on this as much as
we can to quickly make a complete polled bull
available,’ says Pascal Milon of the French breeding program Créavia. From America, Devan Funk of
Accelerated Genetics states: ‘Our daughter-tested

polled bull Dancer has always been very popular. Currently we are aggressively attempting to
create high genomic polled and homozygous
polled animals including those that do not
have Lawn Boy in the pedigree.’
genetics looks great. We expect that a fully
polled Holstein breed is only a question of
time. We are very sure about that,‘ says Josef
Slejtr, sire analyst for Natural Genetics in the
Czech Republic. The Canadian Roy McGregor
is breeder of Arron Doon West Port Mitey and
Magna, two influential bulls in today’s polled
breeding scene. Nowadays McGregor – his
company has the name DairyBullsOnline, in
cooperation with the American AI NBS – is
active in the field of selecting polled bulls and
semen sales. McGregor predicts that ‘In ten
years the Holstein breed will not be polled. It
will be very hard though to sell semen of bulls
that are not polled. The public opinion, thanks
to the unlimited influence of social media, will
play a decisive role in animal welfare legislation. This influence is already felt these days:
in California it is no longer allowed to dock
tails. The popularity of polled bulls is taking
off. American breeders with the top genetically
polled Holsteins will confirm that demand for
young polled bulls is tremendous.’ l
POLLED FUTURE
A number of AIs predict a golden future for
polled bulls. ‘Sales are still at the beginning.
The first of our daughter proven bulls are only
heterozygous polled. But farmers are looking
mainly for bulls with 100 percent polled progeny. This is a reason of popularity of our first
homozygous polled bull Magua. We expect
that homozygous bulls will accelerate demand
for polled genetics. The future for polled
