Abstract The issues of development and implementation of resource-saving technologies in broiler poultry farming have a complex purposefulness and their solution must be scientifically substantiated and cost-effective. The productive qualities of meat chickens and broiler chickens of the productive crosses are significantly influenced by many factors that make up the conditions of keeping and feeding. The use of Apex and Emicidin preparations both separately and in combination with each other when rearing chickens of the broiler parent flock of the Ross 308 cross had a positive effect on their productivity and the quality of hatching eggs obtained at the end of the productive period, at the age of 52 weeks. Egg production per initial hen exceeded that in the control group by 2.6% in experimental group 1 (Emicidin), by 3.2% in experimental group 2 (Apex 3010), and by 5.8% in experimental group 3 (combined use of Emicidin and Apex 3010). The determined zootechnical indicators showed high efficiency of the use of the GerbaStor preparation for the floor rearing of broiler chickens of the Ross-308 cross in conditions of increased stocking density in winter. The difference in the productivity index was 18 units, and in meat yield from 1 m² of floor, it was 1.37 kg (3.8%) in favor of the broilers of the experimental group 2, who received GerbaStor. The profitability of the production and sale of meat of broilers grown under an increased stocking density using the GerbaStor preparation was 3.95% higher than that of broilers in the control group.

The poultry industry in Russia has significant prospects for the development of domestic production of eggs and poultry meat. Insufficient attention is paid to the practical application of enzyme drugs, although numerous studies have proven the effectiveness of these substances in feeding animals and poultry. The purpose of the research was to determine the feasibility and effectiveness of using the multi-enzyme drug Axtra XAP 101 produced by DuPont as part of compound feed for growing broiler chickens. A scientific and economic experiment has been carried out and various doses of the multi-enzyme drug Axtra XAP 101 have been experimentally studied as part of compound feed and the optimal dose in the amount of 7–9 % of the dry matter of the compound feed has been identified. Multi-enzyme drug Axtra XAP 101 influences on indices of meat productivity of broiler chickens. It has been found that this drug increases the average daily increase in live weight of broiler chickens, reduces feed conversion and has a positive effect on the livability of livestock. The highest value for livestock livability has been observed in the 3rd experimental group, where it was 97,67 %, which was by 0,32 % higher than in the control group, by 0,5 % higher than in the 1st experimental group and by 0,57 % higher than in the 2nd experimental group. The European productivity index was the highest in the 3rd experimental group and amounted to 412 points. This indicator was higher than in other groups: higher than the control group by 20 points, the 1st experimental group – by 12 points, the 2nd experimental group – by 5 points. Thus, the effect of using enzymes in wheat and barley diets is to increase and equalize the nutritional value of different varieties and batches of grain. Changing the location and mechanism of microbial fermentation as a result of adding an enzyme also has a positive effect on the health of poultry.

Целью исследований явилось изучение живой массы и среднесуточных привесов цыплят-бройлеров кросса «Hubbard» при введении в питьевую воду препарата фульвиокислоты компании BioSap Technologies. Птицы контрольной и опытных групп получали в период выращивания одинаковый рацион (полнорационные комбикорма престарт, старт-1, старт-2, рост, финиш) в соответствии с возрастом. Птицы трех опытных групп дополнительно получали в питьевой воде 2, 4 и 6% препарата фульвиокислоты, произведенного из сапропеля озера Жарки Тверской области. К моменту забоя в 40-дневном возрасте наилучший результат по живой массе – 2592,97 г – получен в опытной группе 2 (4% препарата), птицы которой достоверно превосходили бройлеров опытной группы 3 (6% препарата) на 203,31 г или на 8,51% (p<0,01). У курочек опытной группы 2 показатель составил 2475,53 г, что достоверно больше по сравнению с курочками опытной группы 3 на 245,53 г, или на 11,01% (p<0,01). Цыплята-бройлеры опытных групп 1 и 2 превосходили по живой массе птиц контрольной группы, у петушков это характерно и для опытной группы 3. Наилучшие результаты по среднесуточному приросту отмечены также в опытной группе 2. Без учета пола результат составил 63,82 г, что достоверно больше по сравнению с показателем опытной группы 3 на 5,05 г, или на 8,59% (p<0,05). Среднесуточный прирост курочек опытной группы 2 равен 60,88 г, что на 6,09 г или на 11,12% больше по сравнению с курочками опытной группы 3 (p<0,01). Цыплята-бройлеры опытной группы 3 без учета пола, а также курочки уступают по этому показателю птицам контрольной группы. Оптимальной дозой дачи препарата BioSap Fulvic Power компании BioSap Technologies цыплятам-бройлерам следует считать добавление 4% в питьевую воду. The research goal was to learn how the live weight and average daily weight gains of «Hubbard» cross broiler chickens change when their drinking water is added with a fulvic acid preparation produced by the BioSap Technologies company. Birds of both the control and experimental groups were fed in the raising period the similar feeding rations (complete-value combined feeds of pre-start, start-1, start-2, growth, finishing) depending on the growth stage of chickens. The birds in the experimental groups were fed additionally 2, 4 и 6% fulvic acid preparations produced from the sapropel of the Tver oblast Zharki lake .By the slaughter time, at the age of 40 days, the best live weight results of 2592,97 grammes were shown by experimental group 2 fed with a 4% preparation, which reliably exceeded the weight of group 3 chickens (6% preparation) by 203,31 grammes, or by 8,51% (p<0,01). With female chickens in group 2 the value was 2475,53 grammes, which reliably exceeded the weight of group 3 chickens by 245,53 grammes, or by 11,01% (p<0,01) Broiler chickens of experimental groups 1 and 2 exceeded the control group, the same was noted with male chickens ot experimental group 2 too. The best results in average daily gain were also recorded in experimental group 2. Sex differences not being considered, the result was 63,82 grammes, which reliably exceeded the weight of group 3 chickens by 5,05 grammes, or by 8,59% (p<0,05). Daily gains of female chickens in experimental group 2 were 60,88 grammes, or 6,09 grammes higher than those in experimental group 3 (11,12%). Broiler-chicken values of experimental group 3, sex not being considered, as well as female chicken gains were lower than those of the control group. The optimum dose of the BioSap Fulvic Power preparation produced by the BioSap Technologies company should be considered that of 4% added into drinking water.

In order to ensure high productivity of poultry compound feeds are required. However, their production is limited by the lack of high-energy and protein feed in the country. In recent years, many farms are increasingly using the reserve of intensification of feed production, such as the cultivation of new and sparsely distributed forage crops. In this regard, more and more attention is drawn to sugar sorghum, which has received a high rating not only as a productive and drought-resistant crop, but also as the culture that has excellent feed qualities. The results of studying the influence of compound feed with sugar sorghum seeds on zootechnical, physiological and economic indicators when raising broiler chickens have been presented in the article. The researches have been carried out on broiler chickens from the age of one day to 42 days. Two groups of broiler chickens have been formed (control and experimental) per 50 heads in each to conduct the experiment. It has been found during the researches that when input in structure of the diet of 30 % of sugar sorghum the increase of live weight of broilers by 4,16 %, the average daily feed intake 2,82 %, and reduced expenditures of feed per 1 kg of daily gain by 1,67 %. The use of experimental compound feed has increased the digestibility of nutrients by broiler chickens: raw protein by 0,48 %, raw fat by 2,50 %, and raw fiber by 4,93 %. It has been found on the base of the results of anatomical cutting of broiler chicken carcasses that the experimental group contained more edible parts and muscles compared to the control group. The level of profitability of broiler meat production in the experimental group has exceeded the indicator of the control group by 5,4 %.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.

Cefotaxime (CTX)-resistant Enterobacteriaceae are still an ongoing challenge in human and veterinary health. High prevalence of these resistant bacteria is detected in broiler chickens and the prevention of their dissemination along the production pyramid is of major concern. The impact of certain on-farm interventions on the external bacterial contamination of broiler chickens, as well as their influence on single processing steps and (cross-) contamination, have not yet been evaluated. Therefore, we investigated breast skin swab samples of broiler chickens before and during slaughter at an experimental slaughter facility. Broiler chickens were previously challenged with CTX-resistant Escherichia coli strains in a seeder-bird model and subjected to none (control group (CG)) or four different on-farm interventions: drinking water supplementation based on organic acids (DW), slow growing breed Rowan × Ranger (RR), reduced stocking density (25 kg/sqm) and competitive exclusion with Enterobacteriales strain IHIT36098(CE). Chickens of RR, 25 kg/sqm, and CE showed significant reductions of the external contamination compared to CG. The evaluation of a visual scoring system indicated that wet and dirty broiler chickens are more likely a vehicle for the dissemination of CTX-resistant and total Enterobacteriaceae into the slaughterhouses and contribute to higher rates of (cross-) contamination during processing.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

The article presents data on the influence of the complex of micro elements (Fe, Cu, Zn, Co, Mn) in the form of aquacitrate on the indices of non-specific and cellular immunity in chicken broilers. The poultry received a fodder, balanced by nutrients, according to its type, age and productivity. Control group of chickens were added standard mineral premix (SP) from inorganic compounds of bioelements. Broilers of experimental groups were given water with a complex mineral additive of aquacitrates. In particular, the chickens of the first experimental group – in the amount corresponding to their content in the standard premix (SP), and the 2nd, 3rd, 4th and 5th experimental groups – in the amount equal to 3/4, 1/2, 1/4 and 1/10 of the content of mineral elements in the standard premix. It was found that bactericidal and lysozyme activity of blood serum (BASB and LASB) were the highest in broiler chickens of the third and fourth experimental groups and exceeded the control values by 5.7 and 5.3%, respectively. In the bird of the second and fifth groups, the studied indicators were closer to the ones in control. However, in the chickens of the group D1, giving them the highest studied dose of aquacitrate of micor elements, the values of BASB and LASB tended to decrease. Concerning the level of CIC in serum, it was the highest in the chickens of the second, third and fourth groups, the lowest in the group D1. A similar pattern is also characteristic for phagocytic activity of pseudoiesinophils (PhA). The bite of half and even the quaternary amount of citrates of micro elements, compared with the amount of bioelements in inorganic form, provided an increase, compared to control, of PhA. At such a dose of micro elements in the nanoform in the blood of broilers, the number of T-total and T-active lymphocytes increased, including T-heeler cells and decreased the relative number of T-suppressors. The bird of the first experimental group was characterized by a decrease in the percentage of T-heeler against the background of a slight increase of T-suppressors. Thus, the results of studies of indices of nonspecific and cellular immunity suggest that micor elements in the nanodisperse form, due to better bioavailability and high bioactivity, have a positive effect on the formation and development of the immune system in broiler chickens at a dose corresponding to 25 and 50%, from recommended quantity of biometals in the standard premix.
