Abstract
While methane, produced as a result of fermentative digestion in the rumen of ruminants and spread into the atmosphere, mostly causes the loss of energy received by feed for animals, it also has a negative effect on the global warming. Biotechnological methods aimed at limiting methane production, which constitutes ecological problems in terms of oscillation into the environment and economic problems in terms of feeding animals, are the methods such as; improving the nutritional value of feedstuff by using biotechnological additives and graft/vaccine and transgenic organisms. These methods have found an extensive area of usage especially in the recent years. In this review paper, the research such as formation of ruminal methane, bacteria which produce methane (methanogen) and biotechnological methods reducing methane production in the rumen have been included. When assessing the available research, it is concluded that biotechnological products and applications used as feed supplement reduce methane production as a result of suppression of the usage of hydrogen of methane producing bacteria, by increasing propionic acid production in the rumen.
