The aim of this study was to investigate the relationship between the gut microbiota and feed efficiency, which is an important parameter in pig production, with economic and environmental impact. The gut microbiota has a fundamental responsibility in nutrient digestibility and influences feed efficacy and metabolism. It provides several functions: supply of enzymes which improve the feed value, metabolism of feed to produce nutrients and synthesis of vitamins useful to the animal body. The animals develop a gut microbiota over time and space. For pigs, the scientists use 16S rRNA amplicon metagenomic sequencing for identify bacteria species and 18S rRNA for fungi. The gut microbiota is an important component of the growth variability in all living organisms, and microbiota knowledge could change the actions to obtain a sustainable and efficient lean meat production.
