A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

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.

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 influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%.

It is the fact with the introduction of the detailed system of normalized feeding in the livestock industry, the productivity of farm animals has increased by 11,2 %. The obvious solution to the problem of feeding pigs with complete feed is seen in the use of feed and feed additives of local production, which will reduce the final prime cost of the product. The purpose of the work was to justify the use of feed additives Nabikat and Glauconite in feeding sows. During the experiment 3 groups of sows have been formed (a control group and two experimental ones). Sows of the control group have been received the main farm diet, sows of the 1st experimental group in addition to the main diet have been received the feed additive Nabikat (0,20 % of the dry matter of the diet), and the 2nd experimental group Glauconite (0,25 % of the dry matter of the diet). It has been found on the base of researches that the input of the feed additive Nabikat in the diet of pregnant sows has increased the prolificacy of sows by 16,3 %, the livability of piglets by 10,9 %, while the expenditures of feed has been reduced by 20,4 %. The lowest feed and digestible protein expenditures per live weight gain of a pregnant sow and a weaning piglet have been observed in the 1st experimental group when the feed additive Nabikat was included in the diet of sows. The highest feed payment for 1 weaned piglet has been observed when feeding the feed additive Nabikat to sows, which allows producing 24,3 heads of piglets in natural terms, in monetary terms of 1,92 heads. At the same time, it is possible to get an additional profit of 6,9 thousand rubles.

Ruminant Feed

An important task for livestock farms is the use of plant feed extracts to improve the effectiveness of dairy production. The development of new alternative drugs based on natural plants allows for the biological protection of animals. Agolin Ruminant is multi-functional feed additive is a mixture of high-quality active ingredients of plant origin, which is designed to optimize consumption and improve feed conversion in the dairy industry. The purpose of the work was to find the increase in the productivity of high-yield cows by using feed additives based on plant extracts on a large number of animals. Production tests have been carried out in the dairy complex of LLC “Tambov-milk” in the Tambov region on Holstein cows with actual productivity at the level of 8500–9000 kg of milk per year. Analysis of cow productivity indicates a positive effect of the introduction of the feed additive Agolin Ruminant in the ration of animals. For example, in the control group of cows for 30 days of lactation the average daily milk yield from 1 cow was 27,44 kg, in the experimental group 28,14 kg, which was more than 700 g or 2,55 %. The introduction of the Agolin Ruminant feed additive into the ration of animals in the experimental group had a positive effect on the fat content in milk, which at the end of the research period was 3,69 % in the control group, and 3,71 % in the experimental group or 0,02 abs.% higher. The protein content in milk in the control group of cows was 3,16 %, and in the experimental group 3,18 % the excess was also equal to 0,02 abs.%. Economic calculations indicate the effectiveness and expediency of using the Agolin Ruminant feed additive in feeding highly productive cows. At the sale price of 1 kg of milk for 29,0 rubles the productivity of cows have been increased by 0,7 kg, and the income from 1 head per day has increased by 17,3 rubles minus the cost of feed additive.

Purpose: estimation of the possibility of using a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin" for normalizing metabolic processes in highly productive cows in the transit period.Materials and methods. Studies were conducted because of the tribal plant of the Leningrad region. Two groups of animals were selected on the principle of analogs (experimental and control) 20 goals in each. The experimental group of cows 21 days before the calving and for 14 days after the calves were given a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin". For the cottage additives, calcium carbonate (chalk) was used as a filler in the amount of 250 g with the addition of 10-15 g. Supplements "BioGrom SC" by 1 head. The mixture was prepared at the rate of 20 goals and a food antibiotic "Monenzin" was added to it at the rate of 100 mg per 1 kg of a mixture of feed additive with filler. The resulting mixture was fed by animals of the experimental group. All animal experimental and control groups take blood for 21 days before the hotel. The total protein, beta hydroxy acid, acetoacetic acid, alkaline blood reserve, calcium-phosphoric ratio, glucose is determined. At the end of the transit period on the 21st day of lactation, the blood of animal control and experimental groups was repeatedly investigated.Results. In the cows of the experimental group, in comparison with the cows of the control group at the end of the transit period, a decrease in such biochemical indicators was observed as beta hydroxy acid (a decrease to 0.84 ± 0.03 mmol / l), acetoacetic acid (decrease to 0.4 ± 0, 04 mmol / l). The animals of the experimental group decreased the content of the general protein (77.0 ± 0.08 g / l). Also, the data of the backup alkalinity of blood (acidose indicator) are within reference values. Calcium phosphorus ratio was also within the normal range.Conclusion. Introduction to the diet of a mixture of feed additive "BioGrom SC" and food antibiotic "Monenzin" normalize some biochemical blood indicators in cows in the transit period. At the same time, without correction of metabolic processes, cows are observed ketosis and acidosis, which can lead to premature disposal of animals from herd and as a result of economic losses. Thus, the use of the mixture is shown for the prevention and treatment of acidosis of the scar, metabolic acidosis, ketosis in cattle of the dairy direction of productivity.
