Natural feed additive is made on the basis of bottom sediments of the steppe reservoirs of the Krasnodar Territory and is a dry powder of a grayish tint. Mineralization of local bottom sediments is 6.5 g / kg, calcium content is 29.7 g / kg, macronutrients from 1.04 to 25.8 g / kg, trace elements from 0.03 to 0.7 g / kg. The medium reaction is from neutral to slightly alkaline. Using sapropel feed additives (SFA), it was possible to increase the gross live weight gain of broiler chickens by 1.7-2.0% while reducing feed costs per 1 kg of gain by 0.5%. All internal organs of the poultry were developed within normal limits. There was profitability increase by 1.1% in growing broilers, when using sapropel feed additives in full feed. Blood biochemical values were at an optimal level. Therefore, this feed additive can be considered as a natural feed ingredient; however, it is necessary to further develop a complex feed additive from natural components that partially or completely meets the requirement of the poultry in biologically active substances and micronutrients.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

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 purpose of the research was to determine the feasibility and effectiveness of using a natural antioxidant of plant origin – dihydroquercetin (DHA), as a biologically active substance, in combination with the main standard diet of broiler chickens. Scientific and economic experience conducted in production conditions on broiler chickens of the "COBB-500" cross allowed us to objectively establish that the addition of the biologically active substance Dihydroquercetin to mixed feed contributes to the increase in meat productivity and safety of broiler chickens. Feeding of broiler chickens was carried out with full-fledged compound feeds, in accordance with the recommendations of the originator for this cross. In terms of energy nutrition and the content of nutrient active substances, they were the same and differed between the groups in the amount of the additive administered. Chickens of the 1st control group received only feed (basic diet), the 2nd experimental group – advanced antioxidant supplement Dihydroquercetin in the amount of 0.5 g per 100 g of feed, the 3rd – 0.75 g per 100 g of feed, and 4th – 1 g per 100 g of feed. The duration of the experiment was 40 days and to clarify the effectiveness of increasing the duration of the broiler fattening period, it was extended to 60 days. Broiler chickens were reared on the floor, temperature and light conditions, air humidity, feeding and watering front of the bird during the experiment corresponded to the recommended standards. As a result of the conducted studies on the effect of adding optimal levels of biologically active feed additive Dihydroquercetin to the diet of broiler chickens, it was found that during the growing period, a higher coefficient of live weight gain was established in broiler chickens of the 3rd and 4th experimental groups, whose live weight increased by 105.32 and 120.48 times by the age of 40 days, while in broiler chickens of the 2nd experimental group by 102.57 times and the lowest–in control group chickens only in 90.96 times. The selected feed additive can be considered as an alternative to the use of feed antibiotics in the feeding of broiler chickens in industrial poultry farming technology.

To increase the meat productivity of broiler chickens during fattening, they used a feed additive in the form of preparations based on humic compounds of sodium and potassium salts in various dosages and methods of giving. As a result of two prolonged experiments, the optimal scheme for the use of feed additives was experimentally worked out. The maximum gain in live weight by 9.7% compared with the control was induced by a feed additive based on a potassium humic preparation in the amount of 10% of the diet given with water and, accordingly, 9.1% with food. Sodium humic preparations were less effective than potassium, when fed in the amount of 10% of the diet with water, the gain increased by 6.7% compared with the control and, accordingly, 5.7% when given with food. When comparing the biochemical and hematological parameters of experimental and control groups of broiler chickens on the 5th day of life, that is, the starting values of their homeostasis, no statistically significant difference was found. Immediately before the experiment and the use of feed additives, the physiological potencies of all chickens were equal and their quantitative indicators were included in a single and homogeneous General population. During the period of using humic compounds that positively affected the metabolic and physiological processes of the macroorganism, as well as provided targeted correction and optimization for the intestinal microbiota, significantly different indicators of live weight gain of chickens were recorded between the experimental and control groups, with a significant difference in the actions of potassium and sodium salts of humic and methods of feeding. It turned out that potassium humic compounds are more effective than sodium, and feeding with water is better than with dry food. But the main thing is that the quantitative indicators of the physiological state of chickens of the experimental and control groups differed little from each other, and in some cases were the same. This indicates the physiology of the impact of feed additives and their safety for the macroorganism, and as a result, it provides a biochemically complete meat raw materials of high sanitary quality. That is, the use of feed additives biochemical and hematological parameters of blood in experimental and control groups consistently were within the physiological norm, which certainly proves that supplements are not excessively strong physiological stressor and provide Norelco functioning of all systems and organs of the organism, and the increased gain in live body weight of chickens of the experimental groups did not negatively affect the sanitary quality and biochemical composition of meat products. The intestinal microbiota in the experimental groups received a drug that showed prebiotic potencies and contributed to the normalization of the microflora composition, as evidenced by the isolation of signal microbionts - indicators of the sanitary well-being of a macroorganism such as Aerococcus viridans and Mycobacterium vaccae, as well as non-pathogenic variants of E. coli.

Abstract The aim of the study was to study the effect of a complex of a multienzyme feed additive (Axtra® XAR 102 TPT (Danisco Animal Nutrition) 0.05% of finished feed; I gr) and in combination with ultrafine particles (UFP) of Cu (1.25 mg / kg; II gr) on productivity and morphobiochemical parameters of blood of broiler chickens (BC). BC were divided into 3 groups (n = 15). The results showed that the combined use of the enzyme preparation (EP) and Cu UFPs has a greater effect on the increase in live weight [19.6% (P < 0.05)]. The introduction of only an EP into the diet has a lesser effect on the increase in live weight, which was 18.8% ahead of the control. In the experimental groups, there was an increase in the coefficient of digestibility of nutrients (P < 0.05). The addition of Cu UFPs increased the digestibility of crude fat [3.3% (P < 0.05)]. Analysis of metabolites in blood serum demonstrates the absence of the toxic effect of the introduced additives. There was a decrease in aspartate aminotransferase: in group I by 8.3%, in group II by 4.6% (P < 0.05). The composition of the lipid profile changed, stimulation of erythropoiesis and an increase in the amount of hemoglobin were registered both with joint and separate feeding of the EP and Cu UFPs. Thus, the introduction of just an EP reduced cholesterol levels by 10%, and in combination with Cu UFPs by 2.15%, triglycerides by 33.1% (P < 0.05). Thus, it was found that the combination of a multi-enzyme preparation and Cu UFPs has the potential to be used as a biologically active feed additive and causes an increase in the digestibility, and therefore, the productivity of BC. The research was carried out with financial support from RSF (20-16-00078).

Experimental studies have shown an increase in productivity, metabolic processes, the effectiveness of the use of nutrients and biologically active substances and the metabolic energy of diets, the health of heifers aged 1–6 months under the conditions of industrial technology of their rearing. Increasing the productivity of heifers is closely related to improving the nutrition system during all periods of rearing with the use of the vitamin complex Vitaminol in diets depending on their age and body weight. The highest effectiveness of rearing young animals has been established when using Vitaminol in doses: 1,3 g/head./day – up to 1 month, 2,4 g/head./day – 2 months, 3,3 g/head./day – 3 months, 4,3 g/head./day – 4 months, 4,8 g/head./day – 5 months and 5,3 g/head./day – at the age of 6 months. Differentiated feeding of optimal doses of feed additives to calves increases the digestibility of dry matter by 1,41–10,8 %, organic matter by 1,6–10,0 %, raw protein by 1,6–6,8 %, raw fat by 1,4–8,7 %, raw fiber by 1,5–3,0 % and nitrogen-free extractive substances by 1,6–6,0 % depending on age and body weight (from 1 to 6 months inclusive). It has a positive effect on the absorption of nitrogen and the use of calcium and phosphorus in the body. The use of Vitaminol in diets of calves contributes to an increase in live weight and average daily gain compared to the control group. In calves up to one month of age (at the dose of 1,3 g/head/day) live weight increased by 6,5 %, the average daily gain by 11,4 %, in 2 months (at the dose of 2,4 g/head/day) these indicators were 2,9 and 2,6 %, respectively, at 3 months (at the dose of 3,3 g/head/day) – 3,4 and 8,2 %, in 4 months (at the dose of 4,3 g/head/day) – 6,7 and 12,8 %, in 5 months (at the dose of 4,8 g/head/day) – 4,4 and 3,6 % and at 6 months (at the dose of 5,3 g/head/day) – 4,3 and 2,7 %, respectively. In order to improve the quality of feeding when rearing calves, more fully realize their genetic potential, increase productivity and use of nutrients in diets and normalize metabolic processes in the body we recommend the optimal doses of the feed additive Vitaminol depending on age (g/head/day): 1,3 – in 1 month, 2,4 – in 2 months, 3,3 – in 3 months, 4,3 – in 4 months, 4,8 – in 5 months, 5,3 – in 6 months. Feed additive Vitaminol enter into the composition of complete feed, wet feed mixtures and feed to calves 1 time per day.
