The gut microbiota has been recognized as a key organ in animals and humans due to its associated functions related to the collection and absorption of nutrients involved in energy expenditure. Specifically, the bovine gastrointestinal tract, considered sterile at birth, is rapidly colonized by bacteria and involves a very complex microbiota in response to various factors such as sex, genetics and the exposome (feed, environmental conditions, stress levels, among others). ). Therefore, disturbances in the intestinal microbiota have been related to the appearance or development of various pathologies or even to losses in the metabolic and immunological capacities of the animal. Thus, the modulation of the microbiota has become one of the main strategies to maintain a healthy intestinal microbiota in animals, ensuring its correct performance in obtaining energy from nutrients and modulating the immune response to improve tolerance and resistance to pathogenic agents.
