The diet provides animals with the nutrients necessary for growth and development and is the main factor affecting their production performance. Due to the microorganisms in the animal gut being closely related to animal growth and health, the diet can also indirectly affect animal growth and health by influencing the microorganisms in the animal gut, such as the nutrients in the diet providing an excellent substrate for microbial fermentation in the animal gut. Intestinal microorganisms are regarded as another "organ" in the animal's body and play a key role in the digestion and absorption of nutrients. A variety of diet components (e.g., fiber, starch, oligosaccharides, protein, fat, etc.), as well as some additives (e.g., antibiotics, probiotics, organic acids, and phenols), may affect the composition of the animal's intestinal flora and alter its metabolite concentration and composition, thus affecting its nutrient metabolism and intestinal health through different pathways. Dysbiosis of intestinal flora can cause a variety of gastrointestinal diseases, such as post-weaning diarrhea and swine pest. Therefore, it is important to study the potential interactions between diet-gut microbial-animal health. Changes in diet nutrients are affecting animals' health and development. As the most complex micro-ecosystem in the intestine of animals, a large number of microorganisms in the intestinal tract is involved in the absorption, distribution, and metabolism of its nutrients and the immunity of the organism, and affect the growth and health of animals. Understanding how diet and nutritional status influence the composition and dynamic operations of animal gut microbial communities, and the innate and adaptive arms of animal immune systems, represents an area of scientific need, opportunity, and challenge. The insights gleaned should help understand the relationship between intestinal flora and nutrients to regulate the balance of intestinal flora for animal health. We welcome submissions of Original Research, Reviews, and Mini-Reviews, including but not limited to the following subtopics:1) Analysis and identification of the role of different levels and compositions of dietary nutrients such as protein, fiber, starch, and electrolyte in the development of animals and their intestinal microbiota2) The detailed mechanism by which dietary nutrients modulate the development of gastrointestinal diseases by targeted or non-targeted (meta)metabolomics, (meta)transcriptomics, and (meta)proteomics approaches in an integrative manner3) Nutritional interventions targeting lessening the prevalence and consequence of gastrointestinal diseases
