Feed efficiency and phosphorus efficiency are of increasing importance in poultry breeding. It was frequently shown that next to the birds' genomes also the gut microbiota composition is important for these efficiency traits. The gut microbiota composition is a mediator between the genomes of the birds and their efficiency traits. In the present study, an approach was taken to consider the animal's gut microbiota diversity, efficiency traits, and the genomes of the animals together in a causal network to decipher the mediator role between the traits. Growing Japanese quail were used as model species. A stable network could be established that placed the diversity of the gut microbiota composition at the forefront, with direct and indirect links to other traits like phosphorus utilization and retention, feed per gain ratio, and growth. Together with genome scans, the results confirmed the mediator role of the gut microbiota composition because several traits associated variants affected the efficiency traits directly and indirectly via the gut microbiota composition.
