Inbreeding depressions for global and partial economic indexes, production, type and functional traits for dairy cattle

Extract
Modern genetic selection programs identify families with superior genetic merit and reproductive technologies which are used to disperse these genotypes throughout the population increasing relationships between animals (Weigel, 2001). However matings of related individuals unavoidably lead to inbred offspring. One of the main economic consequences of inbreeding is inbreeding depression, the reduction of the mean phenotypic value for economically important quantitative traits. The objectives of this study were to use an advanced algorithm to compute inbreeding and to estimate inbreeding depression for traits and indexes that are in the genetic evaluations for Walloon dairy cattle (production traits, type traits and somatic cell score (SCS)).
