ILLUMINATION SYSTEM, AND CHICKEN BREEDING METHOD

PROBLEM TO BE SOLVED: To provide an illumination system for breeding chicken for meat such as broiler, which is capable of efficiently increasing the body weight of chickens.SOLUTION: An illumination system 10 which may be used for breeding chickens, includes: a light source unit 21 that emits light the emission peak wavelength of which is 480-580 nm; and a control unit 31 that controls the light source unit 21 to emit light to illuminate a breeding area of chickens in an early period of breeding of the chickens. The control unit 31 also controls the light source unit 21 to emit white light to chickens in a later breeding period. With this, a high effect for increasing weight of chickens is obtained.SELECTED DRAWING: Figure 2 【課題】ブロイラーなどの食肉用の鶏の飼育において、効率よく鶏を増体させることができる照明システムを提供する。【解決手段】養鶏に用いられる照明システム１０は、発光ピーク波長が４８０ｎｍ以上５８０ｎｍ以下の光を発する光源部２１と、鶏の育成期間における育成前期に、光源部２１が発する光を鶏の飼育領域に照射する制御を行う制御部３１とを備える。また育成後期においては、鶏に白色光を照射することで、高い増体効果が得られる。【選択図】図２
