PROBLEM TO BE SOLVED: To obtain a growth promoter capable of facilitating the growth of the whole animal individual by oral administration, useful as a feed additive, a health (functional) food, a medicine, etc., by including a Ju-myo protein derived from Drosophila melanogaster. SOLUTION: This growth promoter comprises a Ju-myo protein derived from Drosophila melanogaster which can be obtained as a protein having 77,000 molecular weight, for example, by subjecting the supernatant liquid of fry homogenate of Drosophila melanogaster to anion exchange column chromatography such as DEAE-Sephacel, etc., Con-A column chromatography and gel filtration. Preferably a feed for domestic animals, etc., is produced by including the growth promoter. |
