In order to save soybean meal, sunflower oil and reduce the cost of rations, new sources of raw materials can be used. In modern conditions, attention is drawn to the spring colza, the seeds of which can be used as a fat and protein supplement. A limiting factor in the use in poultry nutrition is the presence of glucosinolates in the seeds and erucic acid in the oil, which negatively affect the growth and development, especially of young animals. Breeding work aimed at improving the feed qualities of spring colza seeds contributes to a wider use in the composition of diets for poultry. In growth experiments on broiler chickens the rate of introduction of seeds of spring colza of the 'Nadezhda' variety selected by the Federal Williams Research Center of Forage Production and Agroecology. It has been established that this variety belongs to the "canola" varieties, and its seeds can be included up to 7% (by weight) in the feed composition without adversely affecting the state of the body and the rate of growth of live weight of chickens. The use of colza seeds reduces the use of soybean meal to 4.7% and sunflower oil to 2.3 % (relative). Increases the efficiency of feed in the control up to 61.93% and in the experimental groups (I, II, III, IV) – 62.18, 62.51, 63.62, 62.78%, respectively. The seeds of the spring colza variety 'Nadezhda' satisfy the bird's need for nutrients and ensure equal productivity with the control

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.

Scientific publications describe the positive effect of feed additives and pharmacological complexes on metabolic processes in the body of broiler chickens, in particular, on the protein composition of the blood, meat productivity and protein accumulation in meat. The Peak-Antistress feed additive developed at the Department of Morphology, Physiology and Pharmacology of the South Ural State Agrarian University allows to reduce the technological load on the poultry body by stimulating the general metabolism and complex antioxidant action. Experiments on the use of the feed additive Peak-Antistress were carried out on broiler chickens of the final hybrid of the Arbor Acres cross in an industrial-type poultry farm with floor technology. The poultry was divided into three groups of 6,000 chickens each and kept in one workshop in separate sections. The control group received the main diet, the 1st experimental group received the main diet and feed additive at a dose of 1269 g / t of feed 5 days before slaughter, the 2nd experimental group received the main diet and feed additive at a dose of 1693 g / t of feed 5 days before slaughter. Slaughter of broiler chickens was carried out according to the technological instructions of the enterprise on the 38th day. Against the background of the use of the feed additive in the experimental groups of broiler chickens, stimulation of protein metabolism was observed, as evidenced by an increase in total protein in the blood by 7.9–20.1%, an increase in the level of protein in white meat by 0.1–0.3%, and a tendency to an increase in amino acids in white meat protein by 0.2–12.3%.

Under the environments of the Tyumen region a scientific and research work has been carried out, including an assessment of the influence of antimicrobial substances: colloidal silver, antibiotics and organic acids on the body of broiler chickens. The purpose of the work was to evaluate the influence of antimicrobial substances on the productivity of broiler chickens. The research and laboratory experiment has been carried out in the laboratory of the Northern Trans-Ural Scientific and Research Institute of the Tyumen Scientific Center of Siberian Branch of Russian Academy of Sciences on chickens of the cross ArborAykrs+. Chickens at the daily age have been distributed according to the principle of balanced groups-analogues. The period of chicken rearing was 35 days, during the same period the analysis of the studied antimicrobial substances has been performed. The composition of the test substances was included colloidal silver 10 μg/l, antibiotics (Pulsoceril, Enronite) and the mixture of organic acids (Agrofeed) at the dose of 0,4 ml/l. The results have shown that chickens that have been watered colloidal silver had the gain of live weight for the period of rearing 1850,94 g or lower than chickens in the control group. At the same time, broiler chickens with watering of antibiotics and organic acids exceeded the control group’s analogues. For example chickens of the 1st experimental group where colloidal silver has been watered at the dose of 10 mcg/l every day had the live weight gain during the rearing period lower by 15,56 g and the average daily live weight gain of 0,45 g than chickens of the control group. At the same time broilers of the 2nd experimental group (with antibiotics) and the 3rd experimental group (with organic acids) had the higher gain of live weight during the rearing period by 56,61 and 95,23 g, respectively, compared to the control group. The average daily gain diff erences were 1,62 and 2,72 g. Indicators of morphological and biochemical composition of blood of experimental groups of broiler chickens indicated that they were within the limits of the corresponding physiological norms. At the same time, there were some changes on the part of both red and white blood, which seems to be related not only to the body’s response to feeding, but also to the biochemical processes within the body.

Water treatment by contact non-equilibrium low-temperature plasma refers to innovative methods of processing food raw materials, which requires determining the level of safety of its use to meet the requirements of food safety for humans. The test animals were divided into four test groups with two different basic diets. The tested substances were drinking main water (control group) and plasma-chemically activated water (experimental group); wheat bread (control group) and wheat bread produced using plasma-chemically activated water (experimental group). It was found that there was no significant difference between the control and experimental groups of animals in body weight and its changes during 90 days of the introduction of the test substances into the diet. The amount of water and feed consumed was in direct proportion to the change in the weight of animals in the corresponding diets. The hematological and biochemical analysis of the blood of the test rats did not confirm the toxic or allergenic effect of the studied feeding factors on their organism. An increase in the number of erythrocytes in the blood and activation of the phagocytic activity of experimental groups of animals were confirmed. This confirms the positive effect of plasma-chemically activated water and wheat bread made with its use on metabolic processes in the body of animals. Macromorphological parameters of the body of animals and the results of histological studies of the stomach, liver, kidneys and femur as potential target organs demonstrated the absence of dystrophic-degenerative changes in these organs. A comprehensive study of the food safety of plasma-chemically activated water and wheat bread made with its use proves the possibility of using an innovative method of water treatment in food production.

The results of the application of a complex of Zinc and Manganese chelates to protein, macro- and micro-mineral exchanges in the body of broiler chickens of the Cobb 500 cross-breed are presented. The administration of Zn and Mn chelates in a dose of 0,2 ml/l for chicken broilers of 23 days of age (1st experimental group) during 14 days influenced the increase in the total protein content to 35,3±0,8 g/l, which is 8 % higher compared with the control – 32,5±0,7 g/l (p<0,01 ) The concentration of total Calcium in serum of broiler chickens 37-day-old (end of trial) was higher in the first experimental group by 7,3 % (2,05±0,06 mmol/l) compared to control – 1,9±0,03 mmol/l. In the second group, where chelates were administered in a dose of 0,4 ml/l of water, the Calcium content was 2,0±0,02 mmol/l, which is 5 % more than the control group. The two-week application of Zn and Mn chelates also led to an increase in the level of inorganic Phosphorus in the serum of the first group to 2,6±0,12 mmol/l (+ 11,5 %) compared with the control group. After administration of chelates Zn and Mn at doses of 0,2 ml/l water, the Zinc content was higher by 4,3% (23,5±0,2 μmol/l) compared to control – 22,5±0,34 μmol/l (p<0,01). In the second group, where the dose of chelates was 0,4 ml/l, the concentration of Zinc was 23,6±0,16 μmol/l, which is more than 4,6 % for control (p<0,01). At the end of the study, the content of Manganese in serum of broiler chickens in the first group was 1,9±0,07 μmol/l (p<0,05), which is 10,4% higher compared with the control – 1,7±0,06 μmol/l (3rd sampling). The level of this element in the second group was 2,0±0,08 μmol/l (p<0,01), which is higher by 16,7 % relative to the control. At the end of the experiment, the coupon concentration in the first and second experimental groups was 12,6 and 9,3 % higher, compared with control, 7,0±0,37 μmol/l. In turn, the serum Ferrum content of the first group was greater by 9,3 % (19,3±0,69 μmol/l), and the second by 6,7 % (18,8±0,47 μmol/l) compared to the bird of the control group.

Aim. Study of the effectiveness of the use of the feed additive "Mega HenOn" in the training of chickens of an industrial herd of the cross "Highsex brown" under heat stress. Materials and Methods. Evaluation of the efficiency was carried out for 32 weeks on industrial chickens in the amount of 70 heads. During the experiment, the egg production of chickens (daily), feed costs, and the category of eggs were taken into account. To determine the quality characteristics of edible eggs, GOST 31654-2012 “Edible hen eggs. Technical conditions". Results. The studied additive had a positive effect on the egg productivity of chickens, both during heat stress and during normalization of the temperature regime. At the age of 47-50 weeks (June-July, the ambient temperature during the daytime increased to 38-40°C), egg production dropped sharply, and in the control group it was 79.03%, and in the experimental group, despite the decrease, it exceeded this indicator by 3.63%. At the age of 51-58 weeks (July-August, the increase increased to 36°C), the decrease in egg production continued, but in comparison with the previous period, there was a certain trend towards recovery, which amounted to 85.51%, exceeding the control by 2.22%. The studied feed additive, to some extent, neutralized the negative effect of heat stress on the body of birds. In general, over the period of the experiment, the egg-laying intensity in the experimental group was 89.1%, and in the control group - 87.09%. The cost of producing 10 eggs in the experimental group is 1.29 kg, which is 0.07 kg less than in the control group. The yield of eggs of the category "superior" and "selected" in the experimental group exceeded the control by 0.53 and 16.89%. The yield of eggs of the II category turned out to be higher in the control group and amounted to 29.56%, which is higher than in the experimental group by 13.73%. Conclusion. The use of the innovative “Mega HenOn” feed additive, in the diets of chickens during the heat stress period, contributed to a more complete realization of the genetic potential of birds, due to the stabilization of metabolic processes in the body of birds, an increase in egg production, a decrease in the yield of culling eggs and, as a consequence, an increase in the level of profitability by 2.38%.

The objective of this paper is to investigate the effect of multiphase feeding, i.e. the effect of different mash feeds with multi-phase protein reduction, on growth, main carcass parts and nitrogen content in faeces of broiler chickens. The experiment was conducted on 1216 chickens of Ross 308 provenience, separated by sex. The experiment lasted for 42 days and the standard technology was used. The groups differed in a type of a mash (treatment) given in the starter period, as follows: T1 (control group) was given a mash with 23% crude proteins from day 1 to day 21; T2 - a mash with 23% proteins from day 1 to day 7, followed by a mash with 21.5% proteins given from day 7 to day 21; T3 - a mash with 23% proteins from day 1 to day 14, followed by a mash with 21.5% proteins given from day 14 to day 21; T4 - mashes changed every three days, having 23%, 22.55%, 22.10%, 21.65% , 21.20%, 20.75% and 20.30% of crude proteins, respectively. Slaughtering performance was investigated on a total of 64 broiler chickens, with eight male and eight female chickens used separately for each of the treatments. Nitrogen content in faeces was determined using the pooled sample of faeces. The obtained results showed some differences in the average daily growth of the male and female chickens when comparing the control (T1) and the experimental groups. Those differences were not statistically significant. However, when comparing the male-only groups, it was determined that the experimental group T4 had statistically significantly higher growth than T2 and T3 group. The effect of the multi-phase feeding programme on the breast, thigh and drumstick share of both male and female broilers was not significant. The applied multi-phase feeding programmes resulted in a reduction in the nitrogen content in the faeces. Considering the obtained results, it can be concluded that the multi-phase feeding programmes had no negative effect on the growth and slaughtering performances of broilers. This goes in favour of these programmes, since they can result in some positive economic and environmental effects of production.

The authors of this article evaluated the effectiveness of the use of a feed additive based on soy protein hydrolysate of the enzymatic cleavage method in combination with iodine and selenium in broiler chickens in the framework of studying its pharmacological properties. The indicators of livestock safety in the experimental group by the end of the experiment were 100.0 %, and in the control group − 84.0 %. In the experimental group, the increase in live body weight was 13.9 % higher compared to the group that did not receive a feed supplement. According to the calculations, the cost of compound feed per 1 kg of weight gain of poultry during the growing period in the ex-perimental group was 1.8 kg, which was 14.2 % lower compared to the control group. The slaughter yield of carcasses in the experimental group was 66.7 %, while in the control group − 62.0%. During the veterinary and sanitary examination, it was determined that the meat of the experimental and control group of broiler chickens was obtained from a healthy bird and was of good quality and suitable for further processing.

A study of the safety of the use of feed additive Liaform for the target species – broiler chickens. Liaform is a yellowish liquid with a specific odor. The feed additive contains lactic acid, formic acid, sodium formate, propionic acid and water. Given the composition of the additive, it can be attributed to two functional groups: preservatives – substances or microorganisms that protect feed from damage by microorganisms or their metabolites, acidity regulators – substances that regulate the pH of feed. For the study was formed on the principle of analogues of 3 groups of broiler chickens of 15 heads (control and 2 experimental) from 8 days of age. Feeding of chickens of the control group was carried out by standard complete feed. Feeding of chickens of the first experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg, feeding of chickens of the second experimental group was carried out with standard complete feed, in which feed additive Liaform was applied in 10 times the recommended dose of 20 g/kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It was found that the studied feed additive in 10 times the recommended dose does not have a negative impact on productivity, growth and development of broiler chickens, feed absorption. As a result of the use of Liaform feed additive in 10 times the recommended dose, the live weight of broiler chickens in the experimental group was higher compared to the control and lower compared to the recommended dose. The use of a feed additive in 10 times the dose did not have a negative effect on hematological parameters and serum protein levels, did not cause a negative effect on the condition of internal organs.
