FIELD: agriculture, livestock farming.
SUBSTANCE: invention concerns livestock farming area. In the capacity of optical emission source it is used light-emitting diode device of power 5-15 J/sec. This device includes plugged in chromium-plated of diameter 4.0-5.0 cm 20 light emitting diodes, emitting visible light of wavelength 430, 435, 440, 450, 460 nm, by 4 light emitting diodes with equal wavelength respectively. Light emitting diodes are located on height 45-55 cm from bull-calf back. At that exposition is implemented two times a day for 15 minutes during all growing term.
EFFECT: rising of average daily growth of bull-calf liveweigh.
