Impact of spectrally pure greenand blue light radiationonthe broiler chickens organism

One of the directions of solution search for the stress prevention in modern poultry farming is to find the physical factors of environmental conditions that stimulate the stress-resistance of organisms. A special survey has been undertaken to study the effect of spectrally pure green and blue light emission on the metabolism and productive qualities of broilers in the conditions of the poultry farm in the Tyumen region. Three experimental groups of broilers of the “Gibro G” cross were formed to carry out the investigation. The first group was kept in a section equipped with green light bulbs. The second group was managed with the use of lamps of green and blue light in the ratio of 1:1. The third group of chickens occupied a section equipped with blue light bulbs. The experiment used the Orion Gasolec lighting system. In the course of the experiment, the methods commonly accepted in the zootechnical and veterinary practice were applied. It was established that the monochrome use of green light lamps was accompanied by the formation of maximum meat productivity indicators. Nevertheless, at the same time, survivability per cycle was only 94.1%. The minimum productivity indicators were obtained with monochrome blue light, the average daily gain was only 40.0 g per cycle, and the survivability index per cycle had the highest value compared to all experimental groups. The content of corticoid in the blood was less than in other groups, so less was the poultry mortality due to stress. When illuminated with lamps of two colors, the obtained data of production, clinicalindicators and analysis of the pathologic-anatomical dissection had intermediate values relative to the groups with monochrome lighting. The experimental results indicate the ability of spectrally pure green and blue light radiation to influence the behavior of poultry and their metabolic processes.
