Heritability h2 of the trait body weight (log10) calculated using the animal model, implemented by MCMCglmm. The upper and lower 95% highest posterior density (HPD) intervals represent the credibility intervals of the estimated h2. Models were fitted separately for each experimental group, in all treatments. In addition to the breeding value, Animal, the random effect of tank was included in all models as this improved the fit of the MCMCglmm.
