The behaviour of the broilers is strongly affected by the characteristics of light. The producers of broilers use various programs and lighting fixtures in breeding poultry. The program for lighting offered by IRA-D LTD. consists of a sequence of light regimes. This sequence is consistent with the age of the birds and exercises its influence through the three main factors of light:

    1. Wave length: Two wave lengths of the light spectrum           are used. Their purpose is to develop the immune           system of poultry, build up the bones and muscles,           stimulate the growth and production of protein and           muscle mass.

    2. Intensity of light: The alternating intensity of the light           affects the increase of the BW of the birds, reduction           of the stress and aggression of the birds.

We developed special devices for performing this light program: lighting fixture IR AL 1101 LED BG and block BM AL IR1101 LED BG for automatic control of lighting regimes. The results achieved by the use of our program may be seen in „Project lighting на broilers ROSS308.pdf”, „Project lighting на broilers DUC.pdf”
