The manifestation of mineral deficiency in the body of animals contributes to a decrease in their productivity and the development of diseases such as perversion and loss of appetite, anemia, endemic goiter, rickets, and osteoporosis. One of the ways to solve the problem of mineral insufficiency is the scientific search and development of advanced formula of feed additives based on natural minerals processed by high technologies. The aim of this study is to determine the effectiveness of using modified diatomite as a feed additive for dairy cows. The exeriment was carried out in Ulyanovsk region during 100 days. We formed groups of animals of 50 cows, the 1st group (control) did not receive additives, but only a household diet, in the 2nd group an additive based on modified diatomite was additionally introduced into the diet in a mixture with feed at the rate of 250 g/head/day, . For the physiological experiment, 5 cows were selected by the method of pairs of analogues. It was established that the introduction of additives based on modified diatomite into the diet of cows improves the morphological composition of their blood. Intake of the additive increases milk yield by 24.7% at p<0.05, the amount of milk fat by 16.2 % compared to the control. The effect of afteraction after stopping feeding the additive was revealed. The use of an additive based on a modified mineral is a cost-effective measure that reduces feed costs and gets additional profit. The average daily yield of natural milk increased by 8.2 % for 1 ruble, and a profit of 4.30 rubles was received . There was a decrease in feed costs for the production of 1 kg of natural milk, up to 0.85.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

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.

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.

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%.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

In order to improve the digestibility and absorption of feed, metabolic processes, growth and development of animals, increase the resistance of the body immunomodulatory agents, probiotics, prebiotics, combined enzyme-probiotic feed additives are widely used. The purpose of our work was to conduct comparative clinical trials of the effectiveness of the probiotic feed additive Probion-forte in terms of productivity, blood indices and histological structure of individual internal  pigs organs during fattening. The researches were carried out on 120 piglets of big white breed at the age of 28 days, which were divided into 4 groups with 30 units in each one. The probiotics were added to feed in different concentrations in order to determine their efficiency and examine influence on piglets organism: the first group was given probiotic Probion-forte in dose of 1.0 g/kg (10 weeks); the second one – Probion in dose of 1.0 g/kg (6 weeks) and 0.5 g/kg (4 weeks); the third one was given probiotic Bio Plus 2B in dose of 0.4 g/kg for 10 weeks; and the fourth one was a control group. The compound feed was provided according to norms recommended for big white breed taking into account age. On the 42nd day (6 weeks) and on the 70th day of test 10 units were selected for haematological, pathomorphological and microbiological tests. The productivity of animals of all studied groups was evaluated by the average daily gains, safety, feed conversion and slaughter output. The stabilized with EDTA piglets’ blood was used for morphological studies, and blood serum – for biochemical studies. The clinical trials have shown that the application of Probion-forte, as a feed additive for fattening of piglets within 10 weeks after weaning, did not cause adverse reactions, was well tolerated by animals and contributed to the improvement of the processes of erythropoiesis and leucopoiesis, increased of serum total protein content. The increasing activity of serum transaminases indicated more intense metabolic processes in experimental animals’ organism, which was confirmed by increase in average daily weight gains and slaughter output compared to control. In the microscopic examination of the thymus, spleen, lymph nodes, intestines, liver, the characteristic histological structure of the organs was preserved and indicated their active morphofunctional state throughout the study period. Morphometrically the increase in the height of the villi in the duodenum and the size of the thymus lobes in piglets, which were fed with probiotic feed additives was established. The efficiency and appropriateness of the application of these products was confirmed in the first and second experimental groups. However, the most significant difference was observed in piglets fed with Probion-forte for 10 weeks at a dose of 1.0 g/kg of feed.

Purpose. To prepare a justification for the use of sodium and potassium salts of humic and fulvic acids (humates) as substances with biologically active properties in fish feeds based on the analysis of sources of scientific and technical information and own experimental materials, Findings. A complex general characteristic of humic substances was provided, the mechanism of biologically active action of humates on living organisms was described. Examples of the use of humates in crop production, medicine, animal husbandry and aquaculture were given. The results of our own studies on the use of humates as a feed additive for valuable objects of aquaculture were presented. Prospects for the inclusion of micro-additives of sodium and potassium humates in the composition of fish feed in order to increase fish survival and digestibility of feed were outlined. Originality. To date, the introduction of humates into fish feed as micronutrients was experimental. The analysis of scientific sources and materials of own studies gave the basis for the conclusion about the need of complex detailed studying of mechanisms of effects of humates on fish. In particular, it is of interest to study the protective properties of humates from the accumulation of heavy metals in the body of fish for the use of micronutrients of these substances in fish feeds. Practical value. The use of humate feed additives in aquaculture will help to solve such urgent problems as the prevention of excessive losses of biological material of cultivated objects, reduction of feed costs, improvement of consumer characteristics of food products. Humates, as substances of natural origin with protective and immunomodulatory action, can become substitutes for some synthetic therapeutic and prophylactic drugs. Key words: aquaculture, humates, compound feed, feed additive, growth rate, survival, feed assimilation.
