The present invention relates to a feeding apparatus installed in a farm on the ground or a cage farm on the sea and supplying a feed to a cultured organism and, more particularly, to an automatic quantitative feeding apparatus for a farm using a blower. The feed is supplied by the use of blown air discharged from the blower. The present invention adopts a quantitative distributor that rotates a distribution rotor inside upper and lower covers and circular passage-type feed injection spaces having the same dimensions are radially formed in the distribution rotor. Then, the feed discharged from a feed storage hopper is subjected to sequential injection into the feed injection space of the distribution rotor through the upper cover. The feed stored in the feed injection space can be sequentially supplied toward a water culture tank or a cage net along a feed transport pipe through a dropping pipe connected to each of the lower cover and an air blowing pipe. The direction of the feed injection and discharge through the quantitative distributor and the direction of the rotation of the distribution rotor form an angle of 90 degrees. Accordingly, feed impairment can be minimized and quantitative supply can be performed in an accurate, effective, and economical way. In addition, the amount of feed supply can be accurately determined and a feedback control based thereon can be performed by means of the measurement of the number of revolutions of the distribution rotor. A feed spray is placed on an outlet side of the feed transport pipe and the feed spray is capable of rotating a feed spray pipe in accordance with a desired spray direction. Accordingly, feeding with respect to multiple water culture tanks or cage nets can be performed with the single feeding apparatus.
