In the experiment with swine there was studied the influence of ultra-violet and various doses of narrow-band red radiation on efficiency and safety of animals. It has been established, that efficiency and safety of animal skilled groups in comparison with animals of control group has risen. Use of an ultra-violet and narrow-band red irradiation with frequency rate of inclusion of red light three times has a day allowed to raise average alive mass of young plants of pigs on 2,5 kg or on 9,1% (Р less than 0,01), a daily average gain - on 9,6%(Р less than 0,001) and safety of animals - on 10%
