Abstract: Nutritional value of feedstuff has a direct impact on the animal performance and the quality of animal products. In vitro methods for laboratory estimations of feed degradation are important tools for ruminant nutritionist. These methods are measured either substrate disappearance by quantifying incubation residues or they record fermentation products such as microbial biomass, volatile fatty acid or gas production. In vitro gas production technology, which is based on the relationship between rumen fermentation and gas production, is a in vitro rumen simulation technique. It is simple, economic, quick and low cost, and wildly used to evaluate the nutritional value of feedstuff in ruminant production. The aim of this study is to describe the application and research advances of in vitro GWgas production technology on animal nutrition and classic mathematics models in this area.

Key words: in vitro gas production technology; nutritional value evaluation; fermentation kinetic
