Table 3 Posterior means of the phenotypic variance and their respective posterior standard deviations explained by the microbiota (\(m^{2}\)) and host genetics (\(h^{2}\)), separately, and jointly (\(m^{2} + h^{2}\)) using a Bayesian approach for feed and digestive efficiency traits of growing pigs fed a conventional (CO) diet or a high fiber (HF) diet
