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.

Feed products obtained from rapeseed oilseeds are increasingly used in feeding young animals and in feeding dairy cows. With the introduction into production and use of non-erucic, low-erucic (two-zero, zero) and without glycosinolates in the seeds of spring and winter grape varieties in the Kaliningrad, Lipetsk, Leningrad, Novgorod, Moscow regions, in the Urals., in Western and Eastern Siberia, in Poland. This study is devoted to a fundamentally new technological solution in one closed cycle of industrial production and processing of rapeseed oilseeds with their deep freezing followed by extrusion, feed products with high antioxidant. Antitoxic and sorption properties were obtained to increase the ecological and nutritional value of milk of cows during lactation decay in 8-9 months of their pregnancy. During this period, the production cycle in the body of cows and milk accumulate heavy and toxic metals that adversely affect the metabolism, health and quality of milk during silage type of feeding. The components studied have improved the taste and smell of rations, purify milk and the body from heavy metals. Used different doses of seeds, oil and paste in the diets of cows mixed with feed (after milking).

The influence of such vegetable crops, as table beet and fodder carrots, and natural coniferous extract in the diets of cows in 8-9 months of pregnancy is investigated. The use of food composition caused a decrease in the concentration of heavy and toxic metals in the milk of highly productive black-and-white cows with annual productivity of 6000 kg in the conditions of anthropogenic pollution. The type of feeding-silage-hay application was investigated. Against the background of the main diet animals of experimental groups are additionally fed is 30, 50 and 80 g per head per day of beets and a similar amount of carrots as fodder. Natural coniferous extract (liquid) in a dose of 5.0 ml/head was fed in a mixture with feed. Table beet, carrot and natural coniferous extract ( liquid) with high antioxidant and sorption simultaneously properties in a mixture with feed rations. In this way, it is carried out to supplement the body of cows with a complex mixture of vitamin C, vitamin B, vitamin E, selenium, spicy-aromatic plants. This method allows more successfully solving the problems associated with metabolism, with the accumulation of heavy metals in the milk of animals with a year-round table method of maintenance. The studied phytogenic feed additives caused an increase in the digestibility of nutrients in diets, a significant decrease in the accumulation of Zn, Cu, Pb, Cd, As, Hg, Fe+2 in the body.

The paper describes the features of growing broiler chickens in conditions of large-group cage keeping at workshop No. 3 Patio of OOO Belgrankorm-Veliky Novgorod, Krestetsky District, Novgorod Region. The study used 2-start (11-20 days, granules), 3-growth (21-33 days, granules) and 4-finishing (34 days before slaughter). Broiler diets in the first period contained 1.26 MJ of metabolic energy (EE), the second – 1.28, the third – 1.30 and the fourth – 1.31 MJ (EE), crude protein, respectively (%) 22.42, 21, 49, 20.04 and 18.65. To increase the usefulness of diets and the use of nutrients and EE, the studied amino acids methionine and glycine, both individually and together in a 1:1 ratio, as well as Undevit vitamins, both individually and together with methionine in a 1:1 ratio (% by weight) were exposed to laser radiation of Hubbard broilers in the chest area through the laser beam of the spatial modulator (PM). Ozonation of air in the halls of the building and the poultry was carried out using a domestic ozonizer Rios of Dekont series (mode 3, productivity 20 g/m3). The feed conversion is quite high in 39 days of growing. The lowest consumption of feed (1.33 g/g) by production was observed in broilers of the third experimental group of the fourth scientific in0house experiment against 1.85 g/g in the analogs of the control group.

The growth of production and consumption of dietary poultry meat causes an urgent need to develop and use new and more effective elements of technologically complete compound feed and broiler chicken rearing in the regions. In order to increase the range of non-traditional feed products and feed additives and reduce the deficit of raw protein, amino acids and vitamins, it is advisable to use non-traditional methods to increase the efficiency of compound feed use when broilers rearing. One of the available non-traditional methods for increasing the efficiency of using compound feed in meat production should be considered the use of synthetic amino acids for a new purpose, namely as a modulator of spatial through the infrared laser beam. The purpose of the research was to improve the industrial technology for rearing of broiler chickens using aeroionotherapy and low-intensity laser radiation. Experimental studies have been carried out under the production conditions of poultry house No. 1 (halls No. 2 and No. 3) of the Novgorodskaya poultry farm in the Novgorod region. Broiler chickens of cross Ross 508 have been kept in three-tier BKM-3B cell batteries. The use of low-intensity infrared laser radiation with minimal parameters of the “Uzor 2K-Super” laser (80 Hz wavelength) and air ionization of air oxygen (AN-1 and AI-P aeronizers, modes 2 and 3) against the background of the main diet of cross-Ross 508 broiler chickens improved the state of carbohydrate, protein, fat, amino acid, and vitamin metabolism by increasing the assimilation processes of their body. It has been caused functional activation of the digestive system in it, along with an increase in enzyme, immune and hormonal systems and made it possible to fully realize the level of meat productivity, feed-efficiency and improve some blood biochemical parameters.
