US Patent 3,465,721 (granted Sept. 9, 1969) to Homare Miyazawa, Shoichi Tarui, Masaki Kamada and Hiroshi Masuda, assigned to Gunze Limited and Takeda Chemical Industries, describes a method of rearing fourth- and fifth-stage silkworms on shaped artificial diet. A restricted amount of thin-film, rod, granule or strip diet is fed 2 to 4 times a day, with fasting periods between feedings, to improve feed efficiency, reduce labor and make growth uniform. It describes net and sieve arrangements for separating silkworms from feces and left-over diet, gives tables of diet amounts and feeding areas, and presents five examples with comparisons against known rearing methods, followed by seven claims.
