BOUND FEED AND PROCESS FOR PRODUCING THE SAME

To provide solid compound feed having a desired size, and a simplified method for producing such solid compound feed, particularly solid compound feed having a sufficiently large size to be fed to large fish such as tuna. The preferable compound feed is obtained by selecting one or more kinds of solid feed, of which preferably at least one consists of formed solid feed, more preferably pellets prepared by means of an extruder, secondarily combining them with a heat-labile component in the form of tablets, capsules or powder as needed, and processing the mixture into a mold having a desired size, preferably a spherical or ellipsoidal mold whose diameter or major axis length is 5 cm or longer. A hot melt-type bonding agent selected from the group comprising water-soluble starch, low-viscosity starch powder containing a starch plasticizer, sugar whose degree of polymerization is 10 or lower, and oil or fat which is solid at normal temperature is added to the above mixture and one or more kinds of solid feed are combined via the bonding agent into compound feed. The compound feed may be obtained by packing one or more kinds of feed with an edible casing which has pores on its surface whose size is sufficiently small to prevent the escape of the contents. A method for producing compound feed is provided which comprises secondarily combining one or more kinds of solid feed.
