  5. 5. © Natural Resources Institute Finland3/15/2017 Development of genetic evaluations for industry • Milk yield evaluation for Nordic dairy cattle – Nordic Test Day Model – Dairy cattle of Denmark, Finland and Sweden (Norway) – Holstein, Red Cattle, Jersey – Developing a model that utilizes over 100 million observations on milk, protein and fat yield from over 3 million cows of over 50 000 dairy herds to predict genetic values for over 7 million animals – Developing a model to describe the environmental variation within and across the dairy herds • Udder health evaluation for Nordic dairy cattle – Utilizing observations on milk somatic cell count, clinical mastitis incidences, and on udder conformation to predict genetic values for Nordic dairy cattle
  6. 6. © Natural Resources Institute Finland3/15/2017 Prediction of animals’ genetic values • Animal evaluation and genetic models – Toolbox Developing computationally efficient computing programs for animal genetic evaluation – MiX99 General software package for analysis of large and complex mixed models – Best linear unbiased prediction software for breeding companies and universities – Development of a stochastic method for estimation of genetic parameters  significant reduction in computational time (days in stead of months) • Genetic parameters estimation method for international across-country evaluation – Method to estimate all genetic correlations between 26 countries in one single analysis • Genomic selection and genomic breeding value estimation – Blending/Combining of direct genetic values and estimated breeding values – ClubWare (http//:genomicselection.net) software development for genomic selection

  16. 16. © Natural Resources Institute Finland Performance recording : Organization 3/15/2017 • Milk recording – • ~ 80% of herds under milk recording • those under MR gets advisory, AI, periodic farmers trainings at discounted price • Milk recordings are done by farmers themselves/family members and sent to the MLOY • Edition and checking incoming records done at MLOY with edition rules
  17. 17. © Natural Resources Institute Finland Summary : Information collected 3/15/2017 • Production as well as functional traits – correlated traits • Functional traits: udder health Nordics • Start with few core traits and build stepwisely • Don’t overstreach • Standardize/harmonize traits and recording systems across boundaries • Harness advances in digital and ICT
