Abstract: Microorganisms are ubiquitous in nature, and have special function in degraded plant cell wall. In the animal gastrointestinal tract, the microorganisms is closely related with the growth and metabolism of the host, because of the degraded function contributed to transform plant to nutrition for the animal. Meanwhile, with the techniques and analysis methods improved, modern metagenomics, based on the high-throughout sequencing, was enable us to study microbia in complex environment more convenient. Using modern metagenomics techniques on the animal gastrointestinal microbial could conduce to a greater extent mining functional gene of microbial gene pool, which was not only played an important guiding role in the growth regulation, disease prevention and other basic science of animal, but also in the industrial production, food security and other fields. This review showed the research of metagenomic technology in animal gastrointestinal microbial classification, application etc., in order to provide scientific reference for animal production, microbial fermentation and other related field.

Key words: rumen microbe, intestinal microbia, metagenomics, 16S rRNA
