Gut microbiota and host genetics contribute to the phenotypic variation of digestive and feed efficiency traits in growing pigs fed a conventional and a high fiber diet

Table 4 Rank correlations of genomic estimated breeding values (GEBV) and their respective 95% confidence intervals (CI) between the Gen and Micro+Gen models for feed and digestive efficiency traits recorded for pigs fed the conventional diet and the high fiber diet
