Bayesian estimation of direct and correlated responses to selection on linear or ratio expressions of feed efficiency in pigs

Table 5 Posterior means of direct (bold figures) and correlated (non-bold figures in a row) additive genetic superiorities of the selected group when the top 10% of the population is selected for single trait selection on feed efficiency or production traits (by row), with posterior standard deviations in parentheses

^a\({\text{RFI}}_{\text{G}}\) = residual feed intake estimated from partial genetic coefficients; \({\text{RFI}}_{\text{P}}\) = residual feed intake estimated from partial phenotypic coefficients; FCR = feed conversion ratio; ADFI = average daily feed intake during test period; ADG = average daily gain during test period; LMP = lean meat percentage at end of the test
