Purpose: This study is aimed at studying the effects of the extract of mimoza and castan tanen on the fermentation of rumen. Method and findings: The effects of the extract of mimoza and castane tanene in doses of 0, 25, 50 and 75 g/kg of dried substance (KM) in rumenic fluid on in vitro gas production, dried substance digestibility, microbial protein production and rumen fermentation have been studied. The extract of 25 g/kg to the rumenic fluid was not effective on fermentation parameters except ammonia (NH3) (P>0.05). Nevertheless, the extract of 75 g/kg to the ruminic fluid has significantly reduced the amount of gas obtained from the fermented part, the potential gas production and the total flying fatty acids (UYA), acetic acid, butiric acid, acetic/propionic acid ratio, NH3 level and carbon dioxide (CO2) and methane (CH4) gas production (P<0.01). In comparison with the extract of castane tanen, the extract of mimoza tanen has tended to reduce the NH3 level (P<0.01), slowly decreased the amount of CH4 with the amount of gas obtained from the fermented part (P<0.05), increased the amount of propionic acid (P<0.01), the total UYA, isobuthic acid, the real digestion rate of the dry substance and the ratio of acetic/propionic acid (P>0.05). Overview: As a result, it is possible to say that the rumian extract of up to 50 g/kg KM in the ruminant diet is appropriate to be used in ration, that in the case of higher doses it may have a negative effect on the fermentation of rumin and the use of food, that the reducing effect of the mimosa tan extract in the production of NH3 and CH4 is higher than the castan tan extract.  The importance and effect of the study: Depending on the source and dosage of tanens, microbial fermentation and ration can reduce digestibility. Nevertheless, when you participate in the proper levels of the ruminant rations that donate castane or mimosis, ruminal fermentation can help to reduce the CH4 and NH3 release without any negative impact.
