1 Breeding in Denmark registrations, indices and breeding scheme International Limousin Congress 2012, Technical Meeting Hotel Radisson, Denmark Wednesday 4 th July 2012 Anders Fogh Aim of breeding work Acheive a large genetic progress, that gives all users an economic revenue
2 Setup of breeding work Breeding values (Knowledge Center for Agriculture) Breed planing and breeding goal (Limousin association) Genetic progress AI and performance test (VikingGenetics) Registrations and practical work (Limousin farmers) Characteristics of Danish Limousin Population calves per year 60% with known sire, of which: 15% are sired by Danish AI bulls 3% are sired by foreign AI bulls Mostly small herds 50% of herds: 1-5 calves per year 90% of herds: 1-20 calves per year Some offspring/sire (across years) 50%: 1-25 calves per sire 90%: calves per sire Some use in Dairy herds (5.000 calves per year)
3 Breeding scheme Top females are mated to sires of sons Selection of elite sires and sires of sons Performance test of Young bull calves - Growth, slaughter quality, feed efficiency Field test of young sires - Fertility, calving, growth, slaughter quality, conformation, total merit Selection of top cows - - or future elite bull calves Criteria is total merit index Screening lists are made available for breed society 4 times a year
4 Breeding scheme Top females are mated to sires of sons Performance test of young bull calves - Growth, slaughter quality, feed efficiency Performance test of bull calves Registrations Weight LD area measured by ultrasound Feed intake
5 Performance test of beef bulls Advantages and disadvantages Advantages Test under standardized environment higher heritabilities Unique registrations feed intake and LD area Disadvantages Expensive limited number of bull calves Performance test of beef bulls Genetic evaluation Traits in genetic evaluation Growth rate month LD area Feed efficiency Publication of results to owners and breed association
6 Breeding scheme Top females are mated to sires of sons Performance test of Young bull calves - Growth, slaughter quality, feed efficiency Field test of young sires - Fertility, calving, growth, slaughter quality, conformation, total merit Traits registred on the farm Weaning weigth (200 days) Birth weigth Yearling weigth (365 days) Calving ease Purebred/ dairy crosses Survival at birth Purebred/ dairy crosses Calving interval
7 Traits registred on the farm continued Classification of muscle Classification of body Classification of feet and legs Traits registred at the performance testing station Body gain in test period Area of L.D. Weigth at 7.5 months
8 Traits registred at the slaugtherhouse Carcass classification (EUROP) Purebred/ dairy crosses Carcass weigth Purebred/ dairy crosses Only certified slaughterhouses Pedigree information Identification of calf and parents Service periods for private bulls AI services Pedigree information includes original identification for imported animal/parents

10 Heritabilities Trait Heritability LD, Performance test 0.45 Growth, Performance test 0.40 EUROP, classification 0.30 Weaning weight 0.27 Yearling weight 0.27 Calving ease, direct 0.10 Still birth, direct 0.08 Calving interval traits in genetic evaluation Traits in breeding goal Traits are combined into different indicies Information traits Used to give more accurate estimates for traits in breeding goal
11 Indices related to production Calf ability to grow (Growth) (Yearling weight, net growth rate and growth on performance test) EUROP classification (Slaughter quality) (Classification on purebred) Indices related to function Calf ability to be born (Birth) (Still birth, survival at 200 days, calving ease - purebred) Cow ability to calve (Calving) (Still birth, survival at 200 days, calving ease - purebred) Cow ability to take care of calf (Milk) (yearling weight, net growth rate - purebred) Cow ability to get pregnant (Fertility) (calving interval)
12 Indices for conformation Body conformation (Overall body conformation) Feet and leg conformation (Overall feet&leg conformation) Muscle conformation (Overall muscling conformation) Overall conformation (Overall body conformation, overall feet&leg conformation, overall muscling conformation) Indices in Denmark 2009 Old animals Animals 3-7 years of age has average of 100 Time
