The invention provides a quantitative feed feeder.A clamping convex part is formed around one side of the lower end of a main body.And a hole is penetrated through the corresponding periphery of the clamping convex part.A rod section extending with a knob is led into the hole of the main body.And make the section cut into the central hole of a set of cutting pieces.The other end of the rod section is the corresponding space of the clamping convex part which is against the main body；And the locking convex part around one side of the main body and the knob penetrating through the other end, the outer part of the section bar section is respectively against the corresponding space around the upper end of the frame body.In order to make the main body stably straddle the upper end of the frame body,A container can be placed between the scaffold.With the help of the hand, the knob is turned to drive the cutting piece to rotate.It can move the feed inside the main body between each two compartment parts and drop it into the container towards the blanking port.In order to achieve a simple quantitative supply.本創作是提供一種定量飼料供給器，是採在一主體的靠下一端一側周邊形成一卡掣凸部、及在卡掣凸部的相應周邊貫穿一孔，以配合一旋鈕延伸的一截桿段引入主體的孔、並使該截桿段切入一撥切件的中心孔，在使桿段另端為抵靠在主體的卡掣凸部其相應空間；而該主體一側周邊的卡掣凸部及另端貫穿的旋鈕該截桿段靠外部位則是各別抵靠在架體上端周邊的相應空間，以使主體平穩跨設在架體上端，而在架體其間是可置入一容器；以利手部在轉動旋鈕一併驅使撥切件作轉動，能將主體內部為每兩區隔部之間的飼料撥動並朝落料口落入容器，以達到簡便的定量供給。
