New genetic parameters for national evaluations of production traits in Spanish Holsteins excluding selected base animals from the estimation of genetic variance
Year: 2000
Type: article
Abstract: In Spain, national evaluations for production traits are calculated with a repeatibility animal model assuming heritability 0.25 and repeatability 0.4, while some other countries assume higher values for these parameters (France and Italy use heritability 0.30 and repeatability 0.50, USA 0.30 (average) and 0.55, and The Netherlands 0.35 and 0.55). Various countries had raised heritabilities used in their national evaluations based on recent estimates, as reported by Bagnato et al. (1996) and Van Tassell et al. (1997) for first lactations data and by Janss and de Jong (1999) for first three lactations.
