A feed given in place of natural feed for a specific purpose. In sericulture, silkworms were previously fed only mulberry, but in recent years it has become possible to raise them on artificial feed that does not contain mulberry at all, freeing sericulture from the seasonal fluctuations in mulberry production. This is because research into the mechanism of silkworm feed intake has revealed various different intake inducers contained in mulberry, and these can now be used to attract silkworms to the artificial feed, have them bite it, and then have them swallow and digest it.

特定の目的をもって天然の飼料のかわりに与える飼料。養蚕においてはカイコはクワを唯一の飼料としていたが,近年クワをまったく含まない人工飼料で飼育することが可能となり,養蚕はクワの生産の季節的変動から解放されることになった。これはカイコの飼料摂取の機構の研究によって,クワに含まれる異なったさまざまの摂取誘起物質が明らかにされ,それを応用してカイコを人工飼料に誘引し,かみつかせ,さらにのみこませ消化させることができるようになったからである。
