When raising broiler chickens of the Hubbard cross at 35 days with a large-group cage method of keeping, it is possible to increase the usefulness of diets and feeding due to optimal levels of metabolic energy (MJ/100g) depending on age and body weight: 1.25 – on 0-10 day, 1.28 – on 11-20 day, 1.30 – on 21-33 day and 1.33 – on 34 day and before slaughter. When they are grown, the content of raw organic nutrients in the diet changes: fat – from 3.79 to 6.85%, fiber – from 2.87 to 4.02% and protein – from 21.74 to 18.62%, respectively. To improve metabolism, Complevit, Selmevit and BioMax were used, which were subjected to laser radiation in the area of a bird’s chest. In meat chickens of the experimental groups, in comparison with the control group, the intensity of growth and development is due to better digestibility of nutrients in the diets: dry matter (by 3.4-5.9%), organic matter (by 2.6-5.9%, P-0.001), raw fiber (by 6.4-16.3%). These studied biologically active complexes (BAC) are freely available in the regions of the country, are not expensive and should not be included in the diets of broiler chickens. They are subjected to mandatory laser radiation with an exposure of 8 sec and 15 sec in the chest area. To increase the energy of their growth, there is no need to harvest large, expensive various feed resources. Laser-irradiated components significantly reduce feed consumption at high body weight of broilers.
