Abstract. The introduction of synbiotics and phytobiotics into the diet allows us to optimize metabolism, increase the level of use of feed components, and activate immune processes in the body. The purpose of the work is to determine the effect of “GerbaStor” and “ProStor” feed additives, including probiotic, prebiotic and phytobiotic components, on the morphological and biochemical parameters of the blood of broiler chickens of the “Ross-308” cross. Methods. In the course of a scientific and economic experiment at the age of 29 days, blood was taken from 5 medium-sized broilers by decapitation to determine morphological and biochemical parameters. The blood test was carried out at the Clinical and Diagnostic Center in Ekaterinburg. The morphological examination of blood was carried out in the hemostasis laboratory, on an automatic analyzer ADVIA 120, manufactured by BAYER, as well as by manual counting of formed elements in the Goryaev chamber. A biochemical blood test was performed in a clinical diagnostic laboratory using a Vitros 350 analyzer. Results. The inclusion of “GerbaStor” and “ProStor” in the diet did not adversely affect the metabolic processes of the bird. Morpho-biochemical blood parameters were within physiological values. In the experimental groups was observed an improvement in the assimilation of protein nitrogen, it is evidenced by a decrease in uric acid in the blood serum. In addition, the use of the studied feed was accompanied by the activation of lipid metabolism in the body of birds, which was characterized by a tendency to reduce the amount of triglycerides in the blood serum in individuals of the 1st and 2nd experimental groups. The results of the study showed that when “ProStor” is introduced into the feed concentrate, there is a tendency of decreasing in the activity of transaminases in the body of broilers, which demonstrates a higher resistance of their internal organs, in particular the liver and heart, to unfavorable exogenous and endogenous influences. The academic novelty lies in the fact that new data were obtained on the influence of the studied feed factors, including probiotic, prebiotic and phytobiotic components, on the morpho-biochemical parameters of the blood of broiler chickens.

The article deals with the possibility of using feed additives in the feeding of broiler chickens and the peculiarities of their effect on the poultry organism. Contemporary data on the biological role of nutrients and energy in the feeding of broiler chickens are presented. The characteristics of the main feeds for poultry and the ways of reducing their prime cost in the conditions of broiler farms are given. The basic principles of effective feeding of poultry with forages of different content of metabolic energy and crude protein are considered, taking into account their assimilation in the body. Provided compound feed recipes and practical tips. It is established that high growth rate of broiler chickens in the start and groove periods (5–39 days) is provided by high-protein compound feeds – 23% (1–2 weeks), 21% (3–5 weeks) and exchange energy of 298 kcal and 305 kcal, respectively. With further cultivation in the finish forage the protein content in the forage decreases and the level of metabolic energy increases (up to 309 kcal). However, for each cross applies its own technology of cultivation and different rates of nutrients in raw materials. It is clear that effective breeding of broiler chickens is not possible without the proper rationing and use of protein and feed energy. Of course, provided that the supply of biologically active substances also corresponds to the normalized amount. Thus, the quality of poultry products is directly dependent on the quality of feed and the efficiency of transformation of feed energy into products.

One of the conditions for obtaining high-quality pig products is the use of feed additives, which contain all the necessary biologically active substances, eliminating their deficiency in feed and acting as catalysts for metabolic processes in pigs. That is why the aim of the study was to study the effect of feed additive “Sylimevit” on the enzymatic and non-enzymatic parts of the antioxidant system of piglets after weaning. Two groups of piglets were formed – control and experimental, in the amount of 10 individuals in each group, selected on the principle of analogues – age, breed and body weight. During the weaning period, the piglets were kept under the sow in special machines, had constant access to the mother, and from the age of 5 days – free access to concentrated feed. Feeding of animals was carried out in accordance with the norms for a given age of pigs. Prior to the study, a clinical and physiological examination of the piglets was performed. Their general condition and activity when eating food were taken into account. On the 28th day of life, the piglets were weaned from the sow and regrouped from different nests in order to be further maintained during the period of fattening and rearing with a change in the structure of the diet, which served as technological stress for the animals. From the age of 5 days, piglets of all groups were fed pre-starter feed. Piglets of the experimental group, from 21 to 40 days of age, were additionally fed the feed supplement “Sylimevit” at a dose of 100 mg/kg body weight per day. Feeding piglets Silimevit feed enhances their antioxidant status. The use of this feed additive in piglets contributed to the activation of both enzymatic and non-enzymatic parts of the antioxidant defense system of piglets after weaning, as indicated by an increase in blood 35-day-old piglets superoxide dismutase activity by 26.9 % (P < 0.001), catalase – 41.1 % (P < 0.001), glutathione peroxidase – by 52.7 % (P < 0.05), glutathione reductase – by 53.5 % (P < 0.05), the content of reduced glutathione – by 75 % (P < 0.001). This is due to the fact that silimevit contains active substances such as milk thistle and vitamins, which are strong direct-acting antioxidants and directly interact with free radicals and reactive oxygen species.

Abstract Over recent years, the range of biologically active substances aimed at the productivity increase, animals preservation, feed use efficiency, product quality improvement and product safety has been significantly expanded. In this regard, the study of the effectiveness of hepatoprotective farm-produced feed additives in the diets of broiler chickens is of particular interest to science and practice. The broiler chickens pectoral muscles of the control group contained 68–0.08% of water, 32–0.06% of dry matter, 20.45–0.08% of protein, and 1.62–0.09% fat. In a comparative analysis of the obtained data, it may be concluded that the use of the feed additive Hepatron 85% as a hepatoprotector improves the detoxification ability of the liver and promotes the regeneration of the liver cells. Betaine as a lipotropic agent contributes to the fat oxidation, enhances appetite, and adds muscle mass. When determining the chemical composition of the muscles of the leg, thigh, body, wings and neck, it was established that the broiler chickens of the experimental group contained 70–0.07% of water, 30–0.05% of dry matter, 19.7±0.08% of protein and 2.11±0.09% of fat. Using the feed with the additive Hepatron 85% causes a 0.5% increase in protein and 0.18% increase in fat compared to the meat of the broiler chickens on general feed. Thus, the inclusion of the feed additive Hepatron 85% in the ration of broiler chickens instead of 50% of methionine and choline contributes to an increase in average daily gains and meat quality improvement in a number of indicators.

The paper presents the study on an impact of feed additives Peak anti-stress and SPAO (SPAO-complex) with different lithium content on meat productivity and meat quality of broiler chickens. The feed additives exert a pronounced metabolic effect, have adaptogen properties and allow forming a mechanism that facilitates compensation of the expenditure of the body, which significantly increases upon stress development. It was established that the average daily gain of the broiler chickens increased by 1.8% and 4.3% on the background of using SPAO-complex and Peak anti-stress, respectively, compared to the broiler chickens that did not receive the feed additives in the daily diet. It was shown that addition of feed additives with lithium into a diet led to an improvement of the indices of broiler meat productivity and meat quality: a level of yield of the carcasses of the 1st category increased up to 56.2–79.1%, high organoleptic indices of meat were ensured, the protein content in white and red chicken meat increased and functional-technological properties of minced meat improved. The use of feed additives ensured profitability of industrial poultry production; the highest indices of profitability were established upon introduction of the feed additive Peak anti-stress into a diet — up to 8.67 rubles per each ruble of expenses. The obtained results of the study should be taken into consideration in the technological processes when raising broiler chickens.

Abstract The research is devoted to the study of the influence of the modern antioxidant of the flavonoid group ‘Dihydroquercetin’ as part of the feed combination on the hematological profile and biochemical parameters of the blood of broiler chickens of the KOBB-500 cross. The content of hemoglobin and erythrocytes in the blood of broilers receiving dihydroquercetin increased, which indicates an increase in the intensity of redox processes in the body. The number of leukocytes in all groups was normal, but in the experimental groups their decrease was noted, which indicates the therapeutic and immunostimulating effect of the drug. Evaluation of protein metabolism by the content of total protein and the fraction of albumin in the blood serum showed its positive dynamics within the normal physiological values, which characterizes an increase in the intensity of assimilation processes in the bird’s body. The metabolism of carbohydrates was assessed by the content of glucose in it, and a decrease in its level indicates its increased consumption as an energy component for metabolic processes associated with intensive growth of chickens. An increase in the activity of alkaline phosphatase by 1.3-1.8 times is associated with the active growth of chickens.

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%.

In the conditions of industrial poultry farming, the body of hens is constantly exposed to numerous technological stressors, the least studied of which are long-term ones, that can provoke chronic stress. One such technological stressor is an increase in the level of cage equipment, which is used by producers to obtain a larger amount of products from 1 m2 of poultry area. The aim of this work was to study the physiological state of the hen’s body based on the clinical biochemical analysis of their blood serum, depending on the battery cages height. In the conditions of a modern complex for the production of edible eggs in a poultry house with an area of 2 915 m2, 4 groups of hens were formed, each of them was kept on a separate floor-analogue in terms of area and cage equipment. Each floor was equipped with «Big Dutchman» 3-tier battery cages. Battery cages of each floor were separated from each other by a lattice floor so that cages of 1–3 tiers entered up to the 1st floor, 4–6 tiers – up to the 2nd, 7–9 tiers – up to the 3rd, and 10–12 tiers – up to 4th floor of cage equipment. Biochemical parameters and activity of hens blood serum enzymes were determined on a BioChem FC-360 biochemical analyzer. For this, 30 blood samples with a volume of 1.0–1.5 ml were taken from axillary veins of laying hens in each group at the age of 18 weeks (at the beginning of the study) and at 52 weeks. It was found that increasing the layering of cage equipment does not have a negative impact on the hen’s body. So, for keeping hens in cages of multi-tier battery cages located on floors 2–4 (4–12 tiers), the biochemical status and activity of their blood serum enzymes were within the physiological norm. Whereas, for hens kept in battery cages of the a multi-tiered system on the 1st floor there was an increase in glucose levels of 60.5–71.0%, creatinine – by 9.7–12.3%, phosphorus – 82.6–100.0%, was observed a decrease in calcium to phosphorus ratio 46.7–50.0%, which was confirmed by an increase in the activity of alkaline phosphatase by 22.3–27.0%, as well as an increase in the activity of aspartate aminotransferase by 3.2–13.8%, lactate dehydrogenase - by 48.5–65.1% and gamma-glutamyl transferase – by 16.4–20.6%. It has been proven that the main consequences of chronic stress caused by keeping hens in the lower floor cells of the multi-tiered battery cage are reflected in the biochemical parameters of their serum, namely increased glucose, creatinine, enzyme activity and violation of calcium to phosphorus ratio.
