A synthetic resin pack for use in fermentation of total mixed rations(TMR) is provided to allow a user to check the fermentation process easily with bare eyes, to prevent the rupture of the pack caused by an excessive nitrogen compound gas pressure, and to accelerate adsorption of the nitrogen compound gas to TMR. A TMR fermentation pack(10) comprises an inlet(12) formed on the top, and thermal seal lines(14). The first thermal seal line divides the fermentation pack into two portions, but not completely. A part of the pack is used as a passage(16) between two spaces for air flow. With respect to the first thermal seal line, the upper space is used as a TMR storage(11) and fermentation site, while the lower space is used as a shock absorbing display part(13). The fermentation takes place in three phases of aerobic fermentation, anaerobic fermentation, stabilization, as air travels in and out via the passage between the two spaces.
