When developing functional feed additives it is of interest to use microorganisms that have the ability to take root in the gastrointestinal tract of poultry and normalize its microflora to have a positive effect on the immune system. One of these bacteria is Propionibacterium shermanii, which has a fortifying, immunostimulating, antimutagenic effect, and can reduce the toxic effect of ultraviolet light and chemical compounds. Azotobacter vinelandii, which has probiotic fortifying, antibiotic properties, is effective as a stimulator of the development of the entire microbiota in a contaminated object, and recycles the formed ammonia in bird droppings, was chosen as another microorganism for creating the additive. The purpose of the research was to develop a functional biological additive based on probiotic microflora, using the by-products of crop processing in the formulations, and to select the norms for its introduction into the diet of quails. As a result of the research the technology of joint cultivation of Propionibacterium shermanii and Azotobacter vinelandii strains was developed, a universal starter culture was created that allows to ferment by-products of processing of plant raw materials, a functional additive with immunostimulating, vitamin and provitamin properties for quails has been obtained. The results of the production test confirmed the effectiveness of the developed additive in the diet of quails. Economic efficiency in the application of the proposed functional biological additive has been shown a reduction in feed consumption per 1 kg of live weight gain by 5,13 %. In addition, the economic effect of using the functional biological additive increases. Thus, the profit in the experimental group was 2738,34 rubles, which was 12,45 % higher than in the control group.

Aim. Study of the influence of new feed additives on the formation of productivity and quality characteristics in the production of various types of raw materials of animal origin. Material and Methods. Zootechnical, biochemical and mathematical methods of analysis were used in the course of research. The obtained digital material was processed using method of variation statistics, considering the Student-t validation criteria, using the Microsoft Excel software package. Results. As a result of the research, the effectiveness of the use of new feed additives "CoreMix" and "Vitazar" in fattening Kalmyk young bulls has been proved. Over the period of the experiment, the absolute increase in live weight of animals of the I and II experimental groups, who received the tested feed additives, exceeded the control by 8.9 and 18.5 kg, while the feed consumption per 1 kg of the increase in live weight decreased by 0.4 and 0.7 EKE, profit from sales per head was higher by 696 and 1,690 rubles, and the level of profitability increased by 3.1 and 8.2%. The study of the regularities of the formation of beef obtained from young bulls of the Aberdeen Angus breed, when using the new probiotic supplement "Rodafen" in their diets, showed that at the end of feeding, at the age of 18 months, the pre-slaughter body weight in the control group was 463.9 ± 3.29 kg, whereas in the experimental groups that received the test supplement in different doses, this indicator was significantly higher by 3.7%, 4.7% and 3.9%, respectively. For the purposeful in vivo formation of optimal quality indicators of beef obtained from young bulls of the Kazakh white-headed breed, the efficiency of using extruded feed from insects of the Locusta migratoria (ELM) species has been proven. More heavy carcasses were obtained from the young bulls of the experimental group in comparison with their peers from the control group: the superiority in terms of pre-slaughter live weight was 5.8 kg, or 1.41% (P <0.05), in terms of the weight of a fresh carcass – 5.6 kg, or 2.75% (P<0.05). In terms of slaughter weight, the young bulls of the experimental group exceeded the control by 5.4 kg, or 2.53% (P <0.05). In order to increase the energy of growth and meat productivity of the Simmental young bulls, the expediency of using new feed additives "Valopro" and "Ruprokol" has been proved. The introduction of these feed additives into the diet during the rearing period made it possible to obtain a live weight of 439 kg, one kilogram of which contains 403 g of muscle tissue and 429 g of edible parts of the carcass, which is 5-9% higher than in the control. It has been experimentally proven that when fattening large white pigs up to 100 and 120 kg of live weight, it is necessary to maintain the amino acid content at an optimal level by introducing synthetic amino acids, which provides an increase in live weight gain and a decrease in the age of fattening. For the purpose of the intravital formation of high-quality mutton obtained from the Edilbaev breed of rams in the arid Trans-Volga region, the expediency of using a new feed additive containing organic iodine, selenium and silicon in the diets of young sheep has been proven. To improve the quality of rabbit meat, the expediency of using new feed additives based on antioxidants and organic acids has been proven. Conclusion. The expediency of using new feed additives in the production of beef, pork, lamb and rabbit meat has been proven. The use of the proposed feed additives had a positive effect on the feed intake and digestibility of feed, the formation of optimal quantitative and qualitative characteristics of the raw materials obtained, and an increase in the profitability of production.

The results of researches on the development of new mineral feed additives based on raw materials produced by Uralchem and the study of the eff ectiveness of their use in the rations of lactating cows have been presented in the article. The experiment has been carried out in the conditions of LLC “PF Barabinskoe” in the Dalmatovsky area in the Kurgan region where 3 groups of lactating cows of Black-and-White breed have been formed. Animals in the control group have been received the ration adopted in the farm, the 1st experimental group with the additive RusMA No. 1 at a dose of 150 g, the 2nd experimental group– with the additive RusMA No. 2 at the dose of 350 g. The use of experimental mineral additives in feeding lactating cows allowed us to increase their milk productivity and profi tability of production. At the same time, the best eff ectiveness was shown by the additive RusMA No. 2 at the dose of 350 g/head/day. The use of RusMA additives during the experiment period (105 days) allowed to increase the milk productivity of cows in the 1st experimental group by 6,03 % and in the 2nd experimental group by 8,24 %. Taking into account the fat content in milk, this diff erence was 6,31 and 8,53 %, respectively. The energy value of milk from cows of the experimental groups was higher compared to the control group by 2,45 and 1,76 %, respectively. According to the content of dry matter in milk, cows of the 2nd experimental group exceeded the control and 1st experimental group by 0,39 and 0,12 abs.%, respectively. The maximum milk fat content has been observed in the milk of cows of the 1st experimental group by 0,03 and 0,01 abs.% more than in the control and 2nd experimental groups, respectively. In terms of protein content, the cows of the 2nd experimental group signifi cantly exceeded the control group by 0,10 abs.% and the 1st experimental by 0,04 abs.%. The content of milk sugar in the 2nd experimental group was higher than in the control by 0,30 abs.% and compared to the 1st experimental by 0,11 %. Signifi cantly more calcium and phosphorus were contained in the milk of cows of the 2nd experimental group by 4,58 % (Р ≤ 0,001) and 2,86 % (Р ≤ 0,05), compared with the control group. The expenditures of feed in the EFU for the production of 1 kg of milk in animals of the 2nd experimental group was less by 5,13 % than in control cows and by 2,63 % compared to the 1st experimental group. The prime cost of 1 centner of milk was lower in the 2nd experimental group by 3,94 %, in the 1st experimental group by 2,65 % compared to the control group. The level of profi tability of milk production in the 2nd experimental group was higher by 9,0 and 1,0 abs.% in comparison with the control and 1st experimental groups, respectively.

Prospects for the development of hydrolysis production are determined by the relevance of industrial use of plant biomass to replace the declining reserves of fossil organic raw materials and increasing demand for ethanol, especially for its use as automobile fuel, protein-containing feed additives that compensate for protein deficiency in feed production, and other products. Based on the review of the research results presented in the scientific literature, the analysis of modern methods of liquid-phase acid hydrolysis of cellulose and various types of plant raw materials, including those that differ from traditional ones, is performed. The main directions of increasing its efficiency through the use of new catalytic systems and process conditions are identified. It is shown that the most promising methods for obtaining monosaccharides in hydrolytic processing of cellulose and microcrystalline cellulose, pentosan-containing agricultural waste and wood, are methods for carrying out the process at elevated and supercritical temperatures (high-temperature hydrolysis), the use of new types of solid-acid catalysts and ionic liquids.

Abstract The paper presents the results of fattening young cattle in the conditions of Yakutia with the use of complex feed additives from local natural raw materials in their diets. One of the ways to increase the meat productivity of livestock is to optimize feeding by inserting complex feed additives into their diets. Therefore, studies were conducted to determine the effectiveness of complex feed additives in the fattening of young cattle in the conditions of Yakutia. At the beginning of the experiment, the live weight of the animals in the groups did not differ much, but starting from the age of 12 months, the superiority of the animals from the experimental groups is noted. In the period of 12-15 months of age, the animals from the experimental groups exceeded the growth rate of the control group by 6.70% and 4.76%. In the period of 15-18 months old, the animals of the control group were inferior to the experimental groups by 28.31% and 16.54%. On average, the animals of the experimental groups grew more intensively in comparison with the control group by 12.73% and 8.66 %. Analysis of animal slaughter data showed that the experimental groups were superior to the control group in a number of indicators, such as the mass of the steam carcass by 8.04% and 4.43 %, the mass of visceral fat by 18.59% and 7.39%. The organoleptic evaluation of meat products also confirmed the superiority of the experimental groups over the control group. Thus, the use of complex feed additives in the feeding of young cattle on fattening showed its effectiveness.

The objective of these investigations was to examine the influence of prebiotics based on mannan-oligosaccharides and polysaccharide complexes of micro elements (Fe, Cu, Zn, Mn) on production results and abattoir parameters for broilers of the hybrid Arbor Acres. The experiment was performed on 186 chicken divided into three equal groups, it lasted 42 days and was divided into 3 phases. The first phase lasted 21 days, the second 14, and the third seven days. The complete mix for initial fattening of broilers was used from days 1-21, and complete fodder mixes for closing fattening from days 21-35, and on days 35-42 of the experiment. Feeding was ad libitum and the broilers were maintained in a floor system. Broilers fed mixes of standard raw material composition and the usual nutritive values achieved an average daily growth of 49.10 g at an average daily feed consumption of 115.55 g and with food conversion of 2.35, while the yield was 71.90%. The addition of prebiotics based on mannan-oligosaccharides resulted in an increased average daily growth by 14.95% with a lower feed consumption by 2.67% and better conversion by 15.32%, while the yield was approximately the same as in the control group. The use of mixes to which polysaccharide complexes of micro elements have been added (Fe, Cu, Zn, Mn) resulted in a higher daily growth by 11.43%, with a lower feed consumption by 4.28% and better conversion by 14%. The yield was approximately the same in this group as in the controls. The results realized in these investigations, throughout the experimental period, indicate that the use of the examined additives significantly affected the growth and body mass of chicks and that it is nutritionally and economically justified.

The development of industrial poultry farming requires not only the breeding of new highly productive poultry breeds, but also the development of new rearing technologies and the improvement of standardized nutrition. Currently, in the field of feeding farm animals and poultry an important research area is the search for cheaper non-traditional and affordable feed products that can replace part of the grain in the poultry diet. It is very important to use local raw materials. One of these crops is naked oat, which has the highest energy content, the highest concentration of lysine and methionine among all cereals. The purpose of the researches was to determine the eff ectiveness of using naked oat in compound feed for quails. The results of the influence of complete nutrient-balanced compound feeds with naked oat on zootechnical and economic indicators in the rearing of quails have been presented in the article. It has been found that the live weight of quails in the experimental group has been increased by 3,06 %, while the average daily feed consumption has been increased by 1,83 %. Feed expenditures per 1 kg of live weight gain in the experimental group have been lower by 1,31 % due to the absorption of feed nutrients. According to the results of the balance experiment, the digestibility of raw protein has increased by 1,90, fat by 0,41 %, nitrogen-free extractive substances by 2,77 %. When calculating economic indicators, it has been found that the use of naked oat in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 3,75 %. Despite an increase in the total cost of feed consumed by the experimental group by 2,27 %, the profi t has been received by 9,59 % more. The level of profi tability of quail meat production in the experimental group exceeded the indicator of the control group by 3,40 %.

Increasing the efficiency of feed with the use of different feed additives is becoming a particularly common method in aquaculture. Sangrovit Extra is a plant feed additive for increasing the productivity of farm animals due to the anti-infl ammatory and immunomodulatory properties of its components. The purpose of the research was to evaluate the effectiveness of the use of the Sangrovit Extra additive as part of trout compound feed in feeding rainbow trout when rearing in cages on the warm waters of the regional hydroelectric power plant. The object of research was individuals of rainbow trout. The introduction of the Sangrovit Extra feed additive in the amount of 400 mg/kg into the main diet of fish best contributed to the increase in the average daily gain of trout in cages by 0,48 g compared to the control group. The use of the studied additive contributed to the increase in the assimilation of feed, which was manifested in the indicator of its consumtion. When trout weighing 200–300 g were grown on the main diet (without additives), feed consumption per 1 kg of fish growth amounted to 1,26 kg, whereas when introduced into the feed in the amount of 100 mg/kg, 400 and 700 mg/kg, the efficiency of feed use increased by 9 %, 11 and 5 %, respectively. When rearing larger trout (1,2–1,5 kg), feed consumptions when using the additive in the amount of 400 mg/kg decreased from 1,47 to 1,36 kg, i.e. by 10,8 %. The use of the Sangrovit Extra additive when rearing commercial rainbow trout in cages on warm waters has shown the economic feasibility of its use, especially at the dosage of 400 mg/kg of feed. The level of profitability for rearing trout weighing 0,3 kg was 18,6 % higher, and for fish weighing 0,5 kg by 12,7 % compared to the control group.
