Abstract: PURPOSE: To obtain a highly safe feed composition containing a tea ingredient and a saponin, inhibiting the multiplication of the pathogens of the Crustacea infectious diseases, having an effect for lowering or eliminating the infectious force of the pathogens, and capable of being used instead of antibiotics, vaccines, etc. CONSTITUTION: This composition contains a tea ingredient (preferably the hot water extract of green tea) and a saponin (preferably quillaia daponin obtained from a quillaia hull extract). The tea ingredient and the saponin are usually added to the composition in amounts of 0.05-5% and 0.005-1%, respectively, based on the feed. The composition is preferably administered in the form of pellets for oral administration to shrimps, or in the form of fine particulate powder for oral administration to the larvae of the shrimps. A tea extract containing (-)-epigallocathechin gallate in a high concentration is preferable as the extract of the green extract.
