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 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.

Unbalanced nutrition as well as diseases of infectious and non-infectious etiology lead to a decrease in production and a significant loss of farm animals and birds. To mitigate these problems, various probiotic drugs (probiotics) are introduced into the diets of birds and animals for preventive purposes. The aim of the research was to study the effect of the Vitafort probiotic, containing antagonistic bacteria of the endophytic strain Bacillus subtilis B11, on the body of broiler chickens. The effect of Vitafort was assessed by measuring the live weight and average daily growth of birds. In addition, a morphological study of blood was carried out and the content of Bacillus subtilis in the small intestine was determined. It was found that the endophytic strain Bacillus subtilis B11 improved the intestinal microflora. Thus, on day 5 of its use, the number of microorganisms varied from 4.1 × 104 to 8.2 × 104 CFU/g, and on day 42 the same number varied from 4 × 108 to 5.8 × 108 CFU/g on day 42, the contents of red blood cells, haemoglobin, and white blood cells in the blood of chickens from the experimental group were higher by 6.44%, 3.44%, and 2.11%, respectively, than they were in the control group. Considering the above facts, it can be assumed that the absorption of nutrients in the intestine improved, and metabolic processes were activated due to an increase in the transport abilities of red blood cells.

The body of  broiler chickens is characterized by a high metabolism, which promotes rapid growth and development, but their performance indicators are largely related to housing conditions, which are known to include a number of technological stressors. With the development of stress in the body of poultry changes the course of metabolic processes, which causes changes in all types of metabolism, including protein. The aim of the study was to determine the changes in individual indicators of protein metabolism in the body of broiler chickens against the background of combined stress when included in the diet “Reasil Humic Vet” + “Laktin” and “Reasil Humic Health”. At 13th day of life, all clinically healthy poultry were exposed to combined stress – revaccination (intranasal Newcastle disease) plus cold stress (for 60 minutes by air conditioning and 5 °C in the vivarium). Material for research was selected for 3 days after the action of the stress factor (stage of anxiety), 13, 20 and 26 days after the action of the stress factor (the resistance stage). The material for the study was blood plasma, which determined the concentration of total protein, as well as the content of albumin, globulin fraction (α1, α2, β, γ). It was found that 3 days after the action of stress in chickens of Control group the development of adaptive reactions is manifested by the stability of the total protein content and redistribution of the fractional composition of plasma globulins in the form of increased albumin and α2-globulins. At different stages of development of the stage of resistance in birds of Control group, the content of total protein decreases by an average of 14.6 % due to the content of albumin by 6.9 % and α2-globulins – by 15.9 %, against the background of increasing α1- and γ-globulins by 23.1 and 33.5 % with the stabilization of individual studied indicators at the final stages of development of the resistance stage. The use in the diet of broilers feed “Reasil Humic Vet”, probiotic feed supplement “Laktin”, feed “Reasil Humic Health” under the influence of complex stress helps to increase the intensity of protein metabolism in poultry with the development of adaptation syndrome, as evidenced by the growth of total protein on average by 37.8 % (P < 0.05) and albumin – by 17.0 % (P < 0.05), which indicates an increase in the intensity of protein-synthesizing properties of the organism. In different periods of stress in the blood of broiler chickens Research groups there is an increase in the ratio of individual protein fractions, especially the content of γ-globulins - an average of 21.3 % (P < 0.05), which indicates an increase in the immune status of their body with a predominance of numerical values in the Research 1 group of poultry.

In the conditions of modern technogenic pollution of the environment, environmental problems, improving the quality of livestock products and their food safety is an important and urgent issue today. Pollution of the environment with heavy metals due to man-made activities of the population has led to a number of problems of agricultural production. The aim of the study was to investigate the effect of sodium selenite and feed additive “Metisevit plus” on the protein-synthesizing function and functional state of the liver of rats in lead-cadmium intoxication. It was found that the level of total protein in the blood of rats exposed to cadmium and lead was reduced. These changes were due to a decrease in albumin levels and an increase in globulin levels. Thus, hypoproteinemia resulting from cadmium and lead poisoning may indicate impaired hepatic protein synthesis. Transamination enzymes play a major role in the relationship between protein and carbohydrate metabolism, which is important for switching the oxidation of energy substrates from glucose to amino acid energy nutrition, which is extremely important under the influence of various environmental factors. The most active transaminases are aspartate aminotransferase and alanine aminotransferase. In the study of the activity of aminotransferases in the serum of rats treated with lead acetate and cadmium chloride, an increase in the activity of enzymes in all periods of the study. The highest activity of aminotransferases was on days 21 and 28 of the experiment in the control group of rats, which carried out the combined load of cadmium and lead. Thus, the load of the body of animals with cadmium and lead contributes to the violation of the functional state and protein-synthesizing function of the liver of animals of the experimental groups. With the introduction of sodium selenite into the body of rats, the activity of ALT and AST in the serum of the first experimental group was slightly reduced compared with the control group. However, the activity of these enzymes did not reach physiological values. When setting the feed additive “Metisevit plus” throughout the experiment, it was found that the activity of aminotransferases in the serum of rats of the second experimental group ranged within physiological values. This is due to the hepatoprotective effect of the components of the feed additive “Metisevit Plus”. In the study of protein-synthesizing function of rat liver in experimental lead-cadmium toxicosis, it was found that after application to rats of the first experimental group of sodium selenite on days 14, 21 and 28, the level of total protein in serum gradually increased, but did not reach physiological values. Using the feed supplement “Metisevit plus” rats of the second experimental group, found a slightly higher level of total protein in their blood, which on the 28th day of the experiment reached physiological values and, accordingly, amounted to 66.8 ± 1.99 g/l. It should be noted that when administering the feed additive “Metisevit plus” protein-synthesizing liver function and liver function of rats of the second experimental group were restored faster than when administering sodium selenite to the first experimental group.

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%.

Cattle fasciolosis is quite widespread in the world, including in Ukraine. Animal blood proteins, being in close functional connection with proteins of various tissues, reflect the changes that occur in the tissues and organs of the body during disorders of their metabolic processes caused by pathological factors. The aim of the study was to investigate the level of total protein and its fractions in the blood of cows in experimental fasciolosis. 12 cows of 4–5 years of age, black-spotted breed, were selected for experiment, out of which 2 groups were formed, six animals in each. Animals in the control group were clinically healthy. Animals of the experimental group were experimentally infected with adolescents. During the research, the rules of compulsory experiments were followed - selection and keeping of analogue animals in groups. The cows' diet was balanced in terms of nutrients and minerals. In the study of protein-sensitizing function of the liver of cows, it was found that during fasciolosis invasion, the content of total protein decreased by 13.8 %. These changes were due to a decrease in albumin and an increase in globulins. Thus, in fasciological invasion of cows, the level of albumin in the serum decreased by 24.4 %, and the level of globulins increased by 7.9 %. The value of the albumin / globulin ratio in the blood of infested cows with the causative agent of fasciolosis is quite indicative. It was found that the albumin-globulin ratio in the blood of cows of the experimental group was probably lower compared to the control group of animals. This value of the coefficient, of course, indicates the suppression of protein-synthesizing function of the liver in these periods of research. In the future it is planned to investigate the functional state of the liver of cows with experimental fasciolosis.

Background and Aim: In recent decades, the use of various feed supplements is the current trend in poultry farming, among which phytogenics serve as alternatives to feed antibiotics. This study aimed to examine the effect of feeding various doses of milk thistle extract (Silybum marianum) on the morphological and biochemical parameters of the blood in broiler chickens. Materials and Methods: Experiments were carried out in an industrial poultry farm on broiler chickens of the Hubbard ISA F15 cross for 40 days. One control group and five experimental groups of day-old chickens were formed. The number of birds in each group was 50. Broilers of all groups received complete feed, and the experimental groups received an additional milk thistle extract at doses of 0.1, 0.5, 1.0, 1.5, and 2.0 mg/kg of body weight. Milk thistle medicinal plant extract was obtained using water-ethanol extraction followed by low-temperature vacuum drying. For the assessment of blood analyses, samples were collected from the wing vein of six chickens per group. Using unified methods recommended by the International Federation of Clinical Chemistry, the content of red blood cells, hemoglobin, white blood cells, total protein, protein fractions, triglycerides, glucose, calcium, phosphorus, and the concentration of alanine aminotransferase and aspartate aminotransferase in the blood serum were determined. Results: It was found that the introduction of milk thistle extract into the diet of broiler chickens with the aforementioned doses increased the number of red blood cells, hemoglobin, white blood cells in the blood, as well as a decrease in the level of albumin and an increase in the content of γ-globulins in its serum. Conclusion: The authors assume that the introduction of milk thistle extract into a complete feed for broiler chickens increased the anabolic processes in their bodies, accompanied by increased use of proteins of the albumin fraction as the main material for organogenesis.
