Linear classification in the Belgian Blue cattle breed: phenotypic and genetic parameters.
20 traits recorded on 1168 bulls at performance testing stations were calculated as linear scores. The overall mean score, standard deviation and h2 are tabulated for each trait, as well as phenotypic and genetic correlations among traits. 16 traits had a significant h2 ranging from 0.132 to 0.390. There were high correlations among traits characterizing the typical morphology of Belgian Blue cattle. Genetic correlations of trait scores with traits of economic importance (final weight, price per kg live weight, and net income) are also presented.
