The potential of microbiota information to better predict efficiency traits in growing pigs fed a conventional and a high-fiber diet

Table 2 Mean of the prediction accuracy of phenotypes in the COHFref/COHFval scenario with common environmental conditions for the reference and validation populations: comparison across three models (Gen, Micro and Micro+Gen), with the estimated microbiota value (EMV) and estimated breeding value (EBV) separately, or combined in the Micro+Gen model
