One of the most important industries at the present stage of development of agriculture of the Russian Federation is pig breeding, and the increase in meat production is mainly due to pork. The solution to this problem can be achieved by increasing the productivity of animals, ensuring the full value of their feeding through the rational use of scientifically based for local conditions feed additives. The purpose of the research was to provide a scientific and practical justification for the use of feed additives made from local non-traditional feed resources in feeding young pigs. The experiment has been conducted in the age period of pigs from 120 to 240 days. Gilts of the control group have been fed by compound feed of PCF-6 brand containing standard premix CP-5. Gilts of the 1st experimental group have been received standard feed mixtures in which the normalized trace elements contained in the composition of aspargine soy protein instead of the standard premix, and the 2nd experimental group have been received a standard compound feed in which the normalized trace elements contained in the composition of sapropel humates instead of the standard premix. Based on complex researches the expediency of use of the feed additives made of sapropel humates and asparaginates of protein of soy is scientifically proved and experimentally proved. The conducted studies have allowed to determine the effect of sapropel humates of soy protein asparaginates on metabolic processes in the body of replacement gilts, the intensity of their growth, the formation of performance. It has been found that the absolute gain in live weight in the experimental groups of replacement gilts was 82,9 and 83,1 kg and compared with the control group was higher by 10.8 and 11 %, respectively. Additional profit was 5,45 and 5,54 rubles per head per day, respectively. The results indicate the feasibility of using sapropel humates and soy protein asparaginates in feeding of young pigs.

In order to prevent and maintain the normoflora in the gastrointestinal tract of poultry in the composition of compound feed include various biologically active additives that reduce the pressure of environmental factors on the body. Such additives include a wide range of pre- and probiotics, vitamins, mineral complexes. The purpose of the research was to compare the effectiveness of the use of probiotic feed additives in the diet of replacement young poultry of meat productivity. The tasks of the research were to analyze the dynamics of growth of livestock, its livability, homogeneity of the group, the development of genitals and expenditures of feed for the rearing of replacement chickens and cockerels. The use of the probiotics Levisel SB Plus and Cellobacterin-T in the diet of replacement young poultry at a dose of 0,50 kg/t of compound feed in the period from 3 to 45 days allowed to time of transfer of chickens in parent stock to increase the absolute live weight gain by 4,4 and 2,0 %, to increase the livability of livestock by 0,6 and 0,4 %, yeild of pullet crop by 1,1 and 1,9 %, respectively, Live weight of cockerels that have received probiotic Levisel SB Plus at the age of 147 days exceeded the control group by 2,2 %, and in group has been receiving probiotic Cellobacterin-T it was lower by 1,1 %. At the same time, the livability of the livestock in the groups have been receiving probiotic was higher by 5,1 %, the homogeneity of the group by 0,6–1,9 %. The use of probiotics contributed to an increase in poultry excrements of lacto- and bifidobacteria, a decrease in the group of enterococci and conditionally pathogenic. Probiotics have stimulated in chickens development of organs of ovogenesis, in cockerels of testess. The use of probiotic Levisel SB Plus in the initial period of postnatal development in poultry helped to reduce the expenditures of feed on the rearing of chickens by 1,0 %, cockerels by 1,3 %, and the probiotic Cellobacterin-T, respectively, 7,4 and 10,6 %.

Currently in the South of Western Siberia due to the use of ultra-early corn hybrids it became possible to grow corn for forage grain and actively use it in feeding of cattle. Scientific and economic experiment has been carried out in 2018 on the basis of LLC PF “Partner” in the Mikhailovsky district in the Altai Territory on cows of Simmental breed. In order to conduct the experiment four groups of cows 10 heads in each have been formed. Cows of the control group have received the basic ration balanced for all nutrients. Animals of the 1st experimental group in the main ration, which was fed in an amount of 92,9 % of the main ration 2,5 kg of wet crushed corn grain (WCCG), which was 7,1 % of the nutritional value of the main ration has been added. Analogues of the 2nd experimental group, respectively, were fed 91,5 % of the basic ration and 3 kg WCCG (8,5 % of nutritional value). Cows the 3rd experimental group with 89,9 % of the basic ration and 3,5 kg WCCG (10.1 % of nutritional value) were fed. Wet crushed corn grain has been included in the main ration of first calf heifers during the period of increasing the milk yield from 2 months of lactation for 60 days. During the experiment it has been found that feeding wet crushed corn grain contributes to the trend towards increasing the protein content and reserve alkalinity of the blood serum from 0,8 to 3,8 %. Also in the serum of lactating cows of experimental groups there was an increase in comparison with the control of cholesterol to 5,6 % (P < 0,05), carotene to 69,9 % (P < 0,05) and glucose to 14,6 % (P < 0,01). The most expressed influence on some parameters of biochemical composition of the blood serum had a dose WCCG 3,5 kg/head per day.

The need for minerals and vitamins in cows varies during lactation. It is possible to distinguish critical periods such as the dry period and the first 100 days of lactation when mineral and vitamin availability contributes to the productivity and reproductive function of cows. To balance the rations of trace elements are often used premixes of domestic and foreign fi rms, which do not always meet the requirements of the zone due to excessive or insufficient content of trace elements. Overdose is especially dangerous, because it can cause toxicosis in animals. Therefore, it is necessary to develop local (targeted) premixes for animals depending on the physiological state, i.e. for pregnant dry cows, freshly calved cow during increasing the milk yield period and insemination, during the production of milk, etc. The purpose of the research was to study the influence of the developed mineral premix enriched with critical amino acids on milk productivity and composition of cow’s milk, as well as to study the growth energy of calves, taking into account the provision of the rations of cows with trace elements. The influence of the premix produced with account of trace elements deficiency (Cu, Zn, Co, I) and critical amino acids (lysine, tryptophan, methionine) on milk productivity of cows during the milking period and on the growth of calves have been obtained from controlled animals has been studied. As studies have shown from cows have been receiving premix milk was obtained by 15 % more than from control analogues. Calves have been obtained from cows have been receiving premix had increased growth energy; their average daily live weight gain was higher than the control analogues by 8–10 %.

The use of non-traditional grain feed is one of the ways to strengthen the feed base of the poultry industry and saves food grain. These include triticale as a hybrid of wheat and rye. This crop has a high yield, less demanding on soil fertility, resistant to adverse weather conditions. The prime-cost of production of triticale grain is 30 % lower than wheat and barley. The purpose of the research was to study the effectiveness of the use of triticale grain in feed for broiler chickens instead of wheat. Two research and production experiments in the broilers crosses “Cobb Avian 48” and “Cobb 500” have been carried out. The task of the first scientific and production experiment was to determine the rational levels of triticale grain in feed for broiler chickens. The duration of the experiment was 37 days. The objective of the second research and production experiment in chicken-the broilers was to study the effectiveness of using the drug CelloLux-F in compound feed containing grain triticale. The duration of the experiment was 36 days. As a result of the conducted research rational levels of triticale grain in feed for broiler chickens have been determined; a method for increasing the biological value of plant-type feed with a reduced level of metabolic energy containing triticale has been proposed by enriching them with the enzyme preparation CelloLux-F. The possibility of using compound feed with a reduced level of metabolic energy containing 45 % of triticale grain, while enriching them with the enzyme drug CelloLux-F in the amount of 75 g per 1 ton of feed.

The infl uence of environmentally friendly probiotic preparations based on strains Bacillus coagulans and Bacillus pumilus on the livability of quail population, the intensity of their growth, meat and egg productivity, chemical composition and incubation quality of eggs has been stydied. Experiment duration 152 days has been spent on the quail farm of physiological yard in Siberian Scientific and Research and Design and Technological Institute of Animal Husbandry of the Siberian Federal Scientific Center of Agrobiotechnologies of the Russian Academy of Sciences on Japanese breed quails. Three similar groups per 50 heads in each have been formed in days age. Poultry have been contained in cell battery in accordance with the required climate conditions. Quails of all groups have been received the main diet (compound feed), which has been developed taking into account their age and physiological characteristics. The quails of the 1st and 2nd experimental groups in addition to the main diet consumed with water probiotics based on strains Bacillus coagulans and Bacillus pumilus respectively in the amount of 100 mg/kg of live weight. The drinking these probiotics drugs to poultry has been carried out from a birth days within 21 days. Average daily gain of live weight of quails of experimental groups has been increased in comparison with analogues of the control group by 5,63–12,32 %, the expenditures of feed per 1 g of gain decreased in the 1st and 2nd experimental groups by 8,70 and 15,65 %, respectively. The livability of the quail population of the experimental groups was 91–94 % or 2–5 % higher than in the control group. In the period of productive use of laying hens egg production in the experimental groups increased by 6,10 and 10,71 %, the yield of egg masses by 4,68–10,83 %, which allowed us to reduce the expenditures of feed for production by 10,26–17,95 %. The yield of the incubation eggs in the experimental groups has been increased by 1,0–8,0 % compared with the control group; the incubation waste has been decreased by 9,1–45,5 %.

The classification of the feeding means, a database of the chemical composition and nutritional value of feed has been discussed. Feed are very different in their origin, purpose, chemical composition and nutritional value, physical and technological characteristics. It has been proposed integrated system of the systematization of different feed and feed additives and their main characteristics (purpose, preparation technology, composition, nutritional value, physical and technological characteristics, original raw materials). The complex classifiers has been designed to search the database of information on feed. Signs of division of feed on an origin and appointment are groups, subgroups, types and varieties of feed. Each subsequent level of classifiers groups of feed assorts on the deeper specialization. The classifier uses a six-digit code, which gives a deep characteristic of the feed according to the level of its specialization. All the feed is in the accepted classification have been divided into 8 groups, each group is divided into subgroups, the subgroup is divided on type, type is divided on varieties. This way allows us to use all the advantages of the tree structure of the rubricator and form complex search queries. This classifier has been used to create the database “Chemical composition and nutritional value of feed for dairy cattle, sheep and pigs”, which is the basis for the creation of a system of feeding highly productive animals in a single information space of agriculture and the development of computer programs. The proposed approach to the feeding system is based on the development of a model that should become a technological component of the feeding system of different species and groups of animals, taking into account their needs for energy and nutrients.
