The gut microbiome is a community of millions of microorganisms that coexist, they are organized, have relationships with each other and the host, and help ferment the indigestible fibre content of the horse's diet to produce short-chain fatty acids and more. Massive sequencing of the 16S ribosomal RNA gene has enabled us to identify and learn about the abundance and functionality of the gut bacteria.
''Recent studies have identified the change in the composition of the intestinal microbiome during and after a colic episode, although is not clear if it is a cause or a consequence. The objective of this review was to elucidate whether there is a direct relationship between the changes that occur in the gut microbiome and colic in the equine. A systematized search in Embase, Web of Science, and PubMed was realized. Although there is good evidence that horses with colic have a change in their gut microbiome, it is not fully understood whether these changes are causes or effects. It is necessary to delve into this topic, considering studying larger population sizes. In addition, it would be of great value to previously know the normal intestinal microbiome of a group of healthy horses, which in the future could develop an episode of colic, to compare the before and after in the same individual.''

EquiBiome has a population database of thousands of horses using the 16s gene, we can clarify that horses with colic have changes within the microbiome but these are different depending on what they are fed. For instance, a grass/hay-fed pony with colic will has an increase in verrucomicrobia whilst a racehorse fed a high percentage of formulated food will have an increase in proteobacteria. Verrucomicrobia are strongly linked to metabolism/survival and proteobacteria are linked to gastric infections.
