Problem to be solved: to provide a silo and a silo system suitable for performing anaerobic fermentation by adding moisture, molasses and lactic acid bacteria to the feed rice with high airtightness. Solution: the silo 1 has an overall shape in which the conical base is inverted upside down, and has a container body of an upper opening, a fitting part 3 having a predetermined projecting shape formed integrally with an upper end edge portion of the container body, and an empty portion of the container body provided below the container body A lower discharge portion 10 is provided for discharging at least one of moisture and moisture to the outside. The silo system comprises the silo, a seat member 15 having a sufficient area to cover the upper surface of the silo, and a fitting holding member 16 having a cylindrical shape, and is cut in the longitudinal direction, and the sheet member is covered so as to cover the upper surface of the silo. A fitting holding member is fitted into the fitting portion of the silo to seal the silos. It is preferable that the fixing member 17 further fixes the end and the end of the fitting holding member. Diagram【課題】高い気密性を有し、飼料用米に水分や糖蜜、乳酸菌を添加して嫌気性発酵を行うのに好適なサイロ、及びサイロシステムを提供する。【解決手段】サイロ1は、円錐台を上下逆にした全体形状を呈しており、上部開口の容器本体と、容器本体の上端縁部分に一体成型された所定の突出形状を含む嵌合部3と、容器本体の下方に設けられ容器本体の内部の空気と水分の少なくともいずれかを外部に排出するための下方排出部10と、を備える。またサイロシステムは、このサイロと、サイロの上面を覆うのに十分な面積のシート部材15と、円筒形状で中空で長手方向に切り込みが入れられた嵌合保持部材16と、からなり、サイロの上面を覆うようにシート部材を被せ、サイロの嵌合部に嵌合保持部材を嵌合させ、サイロを密封する。嵌合後に、嵌合保持部材の端と端とを固定する固定部材17を更に有するのが好ましい。【選択図】図2
