The initial results obtained in pigs show associations between the composition of the intestinal microbiota and production parameters. This is the case, for example, with growth: we have also been able to show that there are at least two enterotypes in this species, with one enterotype dominated by the Prevotella genus, more favourable to growth than another enterotype, dominated by the Ruminococus genus. These results obviously need to be confirmed in other populations.
These results also show that there are possible associations between variations in the composition of the intestinal microbiota and immune response parameters. This suggests that the microbiota is indeed involved in a major point of interest: that of robustness and resistance to disease.
We recently published an initial catalogue of intestinal microbiota genes. This information will enable us to exhaustively characterise the microbial content of each individual's microbiota. The aim is to move towards information of a more functional nature than the simple sequencing methods currently used. This information will be more phenotypic than that already characterised.
