Experiences from running a
pedigree recording system for
endangered cattle breeds
Anna Rehnberg, Norwegian Genetic Resource Centre
Seminar ”Challenges and opportunities in the management of animal genetic resources”
Ås, 10 December 2009
Outline
• Introduction of the endangered cattle breeds
• A historical overview of the development of the
Cow Database for native endangered cattle
breeds (Kuregisteret)
• Merging the Cow Database with the National
Recording Scheme for dairy cattle (Kukontrollen)
• Extracts from the Cow Database
• How can we use the recorded data for better
management of the endangered cattle breeds?

Registration of endangered cattle breeds
• Organized by the Committee on Farm Animal Genetic
Resources and the Norwegian Museum of Agriculture
(NLM) in 1989-1991
• Registered breeds were: Døla (DF), Telemark (TF), Western Fjord
(VFF), Western Red Polled (VR) and Eastern Red Polled (ØR)
• Owner, name, breed, date of birth, ancestors
The Cow Database for endangered cattle breeds
• Endangered cattle breeds needed a pedigree
recording system
• A first version was developed in 1990
• Administrated by the Norwegian Museum of
Agriculture until 1. July 2009
• From 1 July 2009 the administration was
moved to the Norwegian Genetic Resource
Centre
The Cow Database for endangered
cattle breeds
• Pedigree print-out for each animal in the herd
• Three generations
• Important tool for the farmers breeding work
• A tool for the public administration
• Monitor the development of the breeds
• Provide breeding advice
• Control system for national production subsidies
A second version of the Cow Database
• Established in 1995 by Nordic Gene Bank
Farm Animals (now Nordic Genetic Resource Center)
• Inbreeding coefficient
• Pedigree completeness
• Possible mating lists
Arguments for a third version of the
Cow Database
• Out-of-date server, a new version of the Cow
Database has been planned for many years
• Strong request from the farmers to only
register in one database
• Include farms with endangered cattle breeds
who only reports registration to the National
Recording Scheme
• Be able to get more information from the
database that can be used for better
management
The third version of the Cow Database
• Reorganization and updating of the Cow
Database started in 2008 and the merging with
the National Recording Scheme was
performed in October 2009 in cooperation with
the Section of Geomatics at the Norwegian
Forest and Landscape Institute
• Cows of the endangered cattle breeds are now
automatically updated from the National
Recording Scheme to the Cow Database
Presented reports are based on
•Female cows (> 2 years)
•Pure bred (>87,5%)
•Five breeds

Future use of the Cow Database
• Data will be used to give advice on public
administration and breeding strategies
• Public administration
• The shown reports from the Cow Database will be used for
monitoring the development of the breeds
• Other reports who are planed to be extracted are
• Number of breeding males per generation
• Number of offspring per breeding female
• Average age of the breeding females
• County level – how many animals of each breed
Future use of the Cow Database
• Advice on breeding strategies
• Extract data that can be used in a inbreeding control program
like EVolutionary Algorithms (EVA)
• Select AI bulls based on their average genetic relationship to
the rest of the population

Merging
• Challenges when merging to databases
• How are farms and animals connected in the to databases and
how can we make sure to merge them correctly?
• Issues that are unproblematic in one database offers a
challenge in the other
• New problems appear when proceeding
• BUT the problems have so far been solvable
• There are still a few challenges left before the merging can
be considered as 100 % full filed and successful
• Although – the database is now more complete than before
merging!!
Reports from the third version of
the Cow Database
• From the National Recording Scheme
• 52 new farms
• 459 new animals
• Total number of farms are now 430
• Total number of animals are now 2550
• 54 % of all farms with endangered cattle
breeds are members of the National Recording
Scheme
• TABELL!!
The third version of the Cow Database
• Reorganization and updating of the database
to prepare merging with the National Recording
System
• Easier than before to extract data
