The present invention relates to a fodder mixer comprising: a fodder container having a space formed therein to store a fodder, and having a cover formed at one side thereof to open and close the space； agitation plates formed in the fodder container to protrude to the inside from the wall surface of the fodder container so as to make fodders skidding and falling on the wall surface mixed with each other while colliding with each other when the fodder container is rotated, wherein each of the agitation plates has a fodder passing hole formed in one side thereof； a left rotation shaft formed in a part corresponding to the weight center of the fodder container, having a shaft hole formed in the center thereof to make the inner space of the fodder container communicate with the outside, and having a position groove formed in one side end thereof； a right rotation shaft formed in a part corresponding to the weight center of the fodder container to be opposed to the left rotation shaft, having a position groove formed in one side end thereof, and having a rotation shaft gear formed in the other side end thereof； an installation rod supporting the fodder container while being separated from the ground； a pair of shaft supports formed to be opposed on the installation rod, and coupled to be rotated while the left rotation shaft and the right rotation shaft are respectively supported thereon and fitted thereto； a motor support formed in one side of the installation rod； an electrical motor installed on the motor support； and a decelerator installed on the motor support, having one side coupled with the electrical motor, having the other side coupled with the rotation shaft gear, reducing a rotation speed of the electrical motor, and transferring the reduced rotation speed to the rotation shaft gear of the right rotation shaft.본 발명은 내부에는 사료를 저장할 수 있는 공간이 형성되어 있고, 일측에는 그 공간을 개폐할 수 있는 덮개가 형성된 사료통； 상기 사료통의 내부에 수개 형성되어 사료통이 회전시 벽면을 타고 미끄러져 내리는 사료가 부딪히면서 서로 섞일 수 있도록 사료통 벽면에서 내부로
