The book combines information about the behaviour that allowed ruminants to survive and to evolve on Earth: the rumen. Furthermore, the reader will find aspects involving rumen anatomy, physiology, microbiology, fermentation, metabolism, manipulation, kinetics and modeling. Thus, the book was not only organized to help students involved in areas such as ruminant nutrition and ruminant production but collegians gathering material for teaching practices.
