Fisiologia ruminal: uma revisão

Abstract

The digestive process is complex in herbivores. Ruminants by having the stomach divided into several compartments, even more their digestion is even more complicated involving several enzymes. These substances are produced by the body itself and the microorganisms housed in the rumen microbial flora. Besides these ingested micro-organisms, it also depends on the type and quality of food ingested by the animals and their pH. Due to the constant variation of the environment and the multiplicity of the system, this work is based only in the normal phenomena, without taking into consideration the possible shortcomings and pathologies. There by it is suggested that this process knowledge is available to every maker, aiming at a good performance in animal production, providing the basis for meal planning. The theme is dedicated to fermentation processing of carbohydrates, proteins, and lipids as well as their absorption by the digestive tract and metabolic transpose to internal medium. It also emphasizes the synthesis of microbial protein and its synthesis by bacteria taking advantage of non-protein nitrogen and also discusses the development of certain vitamins. This is expected to offer a better understanding of rumen physiology, facilitating a more efficient supplementation.
