The Role of Microbiota in Animal Physiology: An Integrative Review

This review examines a broad range of microbiota functions in terms of animal physiology, including its effect on digestion, immunological capabilities, metabolism, reproductive regulation, and nervous system. Its purpose is to provide a systematic overview of on-going research, determine the gap of knowledge and evaluate how environmental factors and the alteration of the microbiome can help to improve the health of animals and contribute to the conservation effort. This study describes the roles of microflora in digestion and absorption of nutrients, modulation of the immune system, and reproduction components and newborn development. Alongside this, it reports the interplay between the bacteria and the central nervous system, which underpins the behavior and mental health. This mission of the review is to offer an integrated overall comprehension of microbiota, which will be used to detect applicable insights and make actionable decisions for future research, veterinary care, and conservation efforts.
