Strategic alliances
to strengthen
VikingJersey
VikingJersey is expanding its breeding programme through
cooperation agreements with strong partners in the United Kingdom,
Norway and France.
C
loser cooperation between major Jersey populations in Europe
will strengthen the VikingJersey
breeding programme, for the benefit of
breeders that support and follow the
breeding goal reflected in the Nordic
Total Merit (NTM) which focuses on balancing health, fertility and production.
Over the last year, three important
agreements have been signed with
relevant Jersey associations and the
breeding procedures to get the most
beneficial results have started in the
populations concerned.
The main goals:
- increasing genetic progress for the
Jersey breed
- identifying more potential breeding
animals
- increasing the pedigree diversity
- lowering inbreeding levels
- creating more interest in breeding
among members of the Jersey associations concerned.
The new breeding agreements have been
initiated with the following associations:
UK Jerseys
• 
Has the second largest Jersey population in Europe and very interesting pedigree combinations in the population.
• All breeding programme procedures
will be as in VikingGenetics countries.
• Starting to screen and test the best
animals in October 2019.
Norwegian Jersey
• Has a long tradition of using Danish
Jersey/Viking Jersey bulls.
• All breeding programme procedures
will be as in VikingGenetics countries.
• Breeding value estimates will be done
in the Nordic evaluation system (NAV).
• Herds are using the VikMate breeding programme.
Evolution (French Jerseys)
• Cooperation started in June 2018,
with all breeding programme procedures as in VikingGenetics countries.
• Classification with Danish software.
International

VikingJersey bulls are doing
extremely well worldwide.
Here is an update of their
outstanding performance:
USA
VJ Gislev #1 among pure bred
daughter proven bulls for JPI
• 8 out of 10 best bulls for
fertility
• 8 out of 10 best bulls for
percentages
• 7 out of 10 best bulls for
somatic cells
UK
VJ Link #1 among daughter
proven bulls for PLI
VJ Hays #1 among genomic

• 7 out of 10 best bulls for PLI
• 8 out of 10 best bulls for
fertility and cell count
South Africa
VJ Garant #1 for SAINET
• 4 out of 10 best bulls for SAINET
• 10 out of 10 best bulls for
Cheese merit
• 5 out of 10 best bulls for
functional udder
Fewer bull calves in future

ore than 60% of the Jersey semen
used in VikingGenetics countries
is sexed, - and the ratio of sexed
semen is increasing rapidly. The main
reasons are to increase genetic gain, when
combining genomic test and using sexed
semen on the best 30% of females, and to

avoid unwanted pure-bred Jersey bull
calves. Added to which, organic dairy
farmers are no longer permitted to cull new
born Jersey bull calves and from 1 January
2022, there will be a total ban on culling.
There is also growing interest in using
beef semen with lowest ranking Jersey
females. This figure is 12.5% today and is
expected to increase to 50% or more for
the poorest genetics in herds. Interest in
using Y-Vik, sexed Beef semen for bull
calves, is also increasing, and several trials
and studies are being done to identify the
best Beef breeds to combine with Jerseys.
