Abstract

Genetic relationships among somatic cell counts (SCC), udder traits, and mastitis have an impact on the value of these traits for breeding programs. To properly utilize these traits for breeding prograrns, detailed information is needed about their interrelationships. In addition, these genetic relationships ane needed to facilitate intemational genetic evaluations. ln the future, multiple trait across country evaluations (both multi-trait and multicountry) nLight be feasible where mastitis sire evaluations would be available on all bulls even though direct recording of mastitis takes place in only a few countries. For example, clinical mastitis, SCC, and possibly some udder type traits from Scandinavian countries could be combined with SCC and some udder type traits from other countries to get multitrait and multirountry evaluations for dinical mastitis. The major benefits of this approach would be the avaitability of tenetic evaluations for clinical mastitis (from correl,ated traits and direct infonnation on relatives) on newly proven bulls in countries where dinical nustitis is not recorded. Genetic correlatiotrs among SCC, udder type traits and mastitis would be reouired to calculate the most accurate sire evaluations possible from the most commonly recorded data. The obiectives of this paper aie to estirEte genetic relationships among somatic cell scores (SCS), productive life (PL), and type traits from the United States (US) and udder health measures from Denmark (DK) and Sweden (SW).
