Abstract
The microbiota of the gastro-intestinal tract : a biological compartment to explore in livestock species In a perspective of safe, competitive and sustainable animal breeding systems, deepening animal phenotyping and defining new breeding goals are identified as major concerns. The intestine hosts a microbial ecosystem referred to as the gut microbiota. The gut epithelium, at the interface between the host and the microbiota, plays fundamental roles in nutrient absorption, local and systemic immune functions, as well as adaptive functions. The onset of high throughput sequencing methods have paved the way toward an unprecedented characterization of the microbiota by producing data on the non cultivable bacteria set. In livestock species, the scientific and technological context is in place to study the gut microbiota at both phylogenetic (bacteria diversity) and functional levels, and analyze the impact on shaping the host phenotype.
