In recent years, a significant part of milk has been produced in farms of various organizational forms, mainly using feeds of their own production. At the same time, there are a number of problems, the solution of which affects the yield, quality and value of products, as well as future prospects in this industry. Scientific research has shown that the intensification of such an industry as dairy farming first of all depends on a strong forage base of the farm. In addition, lactating cows do not need generic feed, but a diet balanced in compliance with detailed rules. Their use makes it possible to increase milk yield by 20 and more percent. Therefore, when organizing a comprehensive feeding, it is necessary to take into account the features of protein, carbohydrate, lipid, mineral and vitamin nutrition. However, even a fully balanced ration does not guarantee the desired effectiveness. In this regard, a variety of feed additives of a natural substance, which also include supplements with probiotic action, deserve a special attention in the system of nutrition. One of these is the Biosprint microbial additive, which contains living yeast cultures (Saccharomyces cerevisiae, MUCL strain, 39885) and belongs to the group of biotic additives. This research is based on the need for the optimization of the limited feeding of milk cows through the use of the Biosprint feed additive in addition to a semi-concentrated type of feeding. Based on the conducted test use (90 days), it is necessary to determine the additive’s effect on the rumen digestion processes, milk yield and qualitative indicators of milk and to determine its optimal content in the diet. It was established that feeding the Biosprint additive as part of the diet contributed to the improvement of the intensity of metabolic processes in cows, in particular, in the rumen. The assumed growth of the number of amylo- and cellulolytic and proteolytic bacteria was detected, which contributed to their enzyme activity and, in turn, led to an intensive hydrolysis of carbohydrate feeds, as a result of which an assumed growth of VFAs as milk fat precursors occurred. Positive results were obtained in terms of the value of milk yield of cows in study groups in comparison with the control group across average daily milk yield by 1.2–2 kg, which constitutes a growth of 5.5–9.2%.There was a stable tendency towards an increase of fat content in milk by 0.05–0.1% and protein by 0.02–0.03%, which indicates an improvement in milk quality. Summing up, conducted study focused on the evaluation of the productive effect of the Biosprint drug on the milk yield of cows and the qualitative indicators of milk make a case for the expediency of the use of the above in the diet structure when feeding milk cows.

The results of research on the use of the feed additive “Ecostimul-2” and natural zeolite from the Khonguruu deposit in the Suntarsky district of the Republic of Sakha (Yakutia) in the rations of lactating cows have been presented in the article. The purpose of the work was to study the influence of feed additives “Ecostimul-2” and zeolite on the digestibility of nutrients and nitrogen metabolism in lactating cows of Kholmogorskaya breed under the conditions of Central Yakutia. Chemical analysis of feed, accounting of dairy productivity of cows has been carried out according to generally accepted methods. The cows of the control group have received the main ration. The cows of the experimental groups have been additionally received to the main ration: the 1st experimental feed additive “Ecostimul-2” in the amount of 200 mg/head/day, and the 2nd experimental group – “Ecostimul-2” in the amount of 200 mg/head/day and zeolite 200 g/head/day. The inclusion in the ration of lactating cows of Kholmogorskaya breed under the conditions of Central Yakutia of feed additives “Ecostimul-2” and zeolite of the Suntarsky deposit together has increased the digestibility of feed in the ration and improved the digestibility of nutrients and nitrogen metabolism. It has been found during the experiment that in cows have been receiving the feed additive “Ecostimul-2” and zeolite with the main ration (the 2nd experimental group) the average daily milk yield was 9,06 kg with a fat content of 3,8 % or was by 10,4 % higher than in the control group. In cows that have been received feed additive “Ecostimul-2” (the 1st experimental group) the average daily milk yield was 8,76 kg with the fat content of 3,77 % or was by 6,8 % more than in the control group.

In order to compensate for the lack of energy in the ration of lactating cows, optimize carbohydrate metabolism and maintain health, specialized feed additives are often used, which include components that make up for or stimulate metabolic processes during metabolism, which reduces the accumulation of ketone bodies. The researches have been carried out in CJSC Glinki in the Kurgan region (Russia). The cows of Black-and-White breed were as the object of research. The purpose of the research was to provide practical justifi cation for the use of modern energy additives in the rations of highly productive cows during the period of increasing the milk yield. It has been found in the course of the conducted research that the cows of the 1st experimental group received in addition to the main ration the energy feed additive Enermix plus in the amount of 250 g/head/day milk yield of natural fat content was highest and exceeded by 273,42 kg or 7,59 % (P < 0,05) of the control group’s herdmates. It has been found in terms of milk at 4 % fat content that for 100 days of lactation 3915,03 kg of milk has been received from cows of the 1st experimental group, which was by 332,55 kg or 9,28 % (P < 0,05) more than from analogues of the control group. At the same time, the yield of milk fat in the milk of cows of the 1st experimental group was 157,67 kg, which was more than the same indicator of cows of the control group by 14,88 kg or 10,42 % (P < 0,05). It has been found that additional feeding of highly productive cows of Black-and-White breed of energy feed additive of domestic production Enermix plus in the dose of 250 g/head/day increases the level of their milk productivity and has a positive infl uence on the composition of milk and economic indicators 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.

The purpose of the research was to study the effectiveness of the use of rations for freshly calved cows during the increasing the milk yield period with the use of new mineral granulated complexes produced by Uralchem LLC. The results of research on the replacement of the mineral part of the vitamin and mineral premix in the rations of lactating cows with the mineral granular complex developed according to two recipes have been presented in the article. Research has shown that cows of the 1st and 2nd experimental groups during the experiment period gave more milk than their herdmates from the control group by 70,8 (P ≥ 0,95) and 106,2 kg (P ≥ 0,95). Due to the higher milk yield of animals that consumed the granulated complex, the yield of milk fat was greater than that of the control analogues by 3,21 (P ≥ 0,95) and 5,17 kg (P ≥ 0,95), protein by 2,70 and 4,30 kg (P ≥ 0,95). The milk yield of cows of the 1st and 2nd experimental groups for 305 days of lactation was higher than in the control group, respectively, by 205,3 (P ≥ 0,95) and 296,8 kg (P ≥ 0,95). In the milk of cows that consumed the granulated complex, there was a tendency for a higher content of dry matter (0,09 and 0,16 %), lactose (0,01 and 0,06 %), nonfat milk solids (0,09 and 0,07 %), ash (0,05 and 0,05 %) in comparison with analogues from the control group. A similar trend has been established between groups of cows in terms of milk density, acidity and rennet coagulability. The revenue from the sale of milk produced from cows of the 1st and 2nd experimental groups was more than in the control group for the experimental period (120 days) by 2074,6 and 3344,0 rubles and for the 305 days of lactation by 7055,4 and 9950,6 rubles.

Unbalanced mineral and vitamin nutrition of lactating cows can be a critical factor in the realization of their productive potential. The development and introduction into production of inexpensive, but effective feed additives is the main trend of improving the feeding of modern animal husbandry. Under the conditions of the Tyumen region such natural raw materials can be sapropels, which successfully combine a variety of biologically active substances. The purpose of the research was to study the digestibility of nutrients and energy metabolism in lactating cows when sapropel is included in the ration. Scientifi c and economic experiment in the study of the effectiveness of feeding sapropel lake Nepryak has been carried out in the training and experimental farm of the State Northern Trans-Urals Agrarian University. The animals of the control group have been fed the main diet. Cows of the 1st and 2nd experimental groups have been fed 300 and 500 g of sapropel per head/day, respectively, in addition to the main ration. It has been found as a result of research that the introduction of sapropel into the ration of cows has a positive effect on the digestibility of nutrients. The digestibility coefficients were higher in the animals of the 1st and 2nd experimental groups compared with the cows of the control group. Cows from the experimental groups digested all the organic substances of the ration better. During the experiment period cows of the 1st and 2nd experimental groups in contrast to the control group had higher milk yield by 11,31 and 10,38 %, respectively, milk protein yield by 10,56 and 5,95 %, milk fat yield by 17,18 and 12,99 %. It has been established that the introduction of sapropel into the ration of cows has the positive effect on the digestibility of nutrients, contributes to the increase of milk productivity, normalizes the metabolism in the body.

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.

Abstract Research has been carried out on the use of the symbiotic “Rumimaster” in balanced diets of highly productive cows in the conditions of the breeding plant “Kirovskaya meadow-bog experimental station”. The experiment was carried out on two groups of animals in the middle of lactation with a duration of 90 days. The inclusion of the feed additive “Rumimaster” in the diet of experienced cows contributed to an increase in the gross production of natural and 4% fat milk by 124.5 kg and 128.4 kg, the yield of milk fat and milk protein by 5.2 and 4.1 kg, respectively. … The differences between the groups for these parameters were in the range of 5.1-5.7%. The productivity of cows for 305 days of lactation in the experimental group was higher than in the control by 7.5%. The symbiotic “Rumimaster” promoted the activation of digestion processes, which was reflected in the increase in the time of feed consumption and the duration of the chewing gum. The cows of the experimental group showed an increase in the level of digestibility of the main nutrients. In terms of the digestibility of crude protein and crude fiber, the experimental group of cows significantly exceeded the indicators of the control group by 3.3 and 3 absolute percent, respectively. The blood biochemical parameters of the animals of the experimental and control groups were within the physiological norm. The economic evaluation of the research results showed the effectiveness of the use of the symbiotic “Rumimaster” in the diets of lactating cows, which was expressed in the receipt of additional profit from one cow in the amount of 1,344.79 rubles for the period of experience and an increase in the profitability of milk production by 2.1 absolute percent.

In recent years, Montbeliard cattle have been imported to France from Uzbekistan in order to strengthen the breeding base of cattle and create high-yielding herds and increase livestock production. However, the productivity characteristics of cattle of this breed have not been studied in our hot climate conditions in special studies depending on various factors. Studies have shown that the level of milk yield of co-breeding Montbeliard cows imported to Uzbekistan depends on the type of production. It was found that the milk yield of lactating cows is 672.5 and 958.5 kg higher than that of dairy and meat-milk cows, respectively, and the level of feed coverage is higher than that of dairy products. It is based on the fact that the milk yield of cows also depends on the biomass index and service life. It was found that cows with a biomass of 531-550 kg, typical of the milk type, produced high milk yields. The level of milk productivity of cows is inextricably linked to the service life. Dairy cows with a service life of 81-90 days are characterized by high milk content, milk fat consumption and 4% milk yield. The selection of cows for the optimal service life is an important factor in the creation of productive dairy herds.

Feed additives have received increasing attention as a viable means to reduce enteric emissions from ruminants, which contribute to total anthropogenic methane (CH4) emissions. The aim of this study was to investigate the efficacy of the commercial feed additive SOP STAR COW (SOP) to reduce enteric emissions from dairy cows and to assess potential impacts on milk production. Twenty cows were blocked by parity and days in milk and randomly assigned to one of two treatment groups (n = 10): supplemented with 8 g/day SOP STAR COW, and an unsupplemented control group. Enteric emissions were measured in individual head chambers over a 12-h period, every 14 days for six weeks. SOP-treated cows over time showed a reduction in CH4 of 20.4% from day 14 to day 42 (p = 0.014), while protein % of the milk was increased (+4.9% from day 0 to day 14 (p = 0.036) and +6.5% from day 0 to day 42 (p = 0.002)). However, kg of milk protein remained similar within the SOP-treated cows over the trial period. The control and SOP-treated cows showed similar results for kg of milk fat and kg of milk protein produced per day. No differences in enteric emissions or milk parameters were detected between the control and SOP-treated cows on respective test days.

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.
