The purpose of the work was the correction rumen fermentation in the transition cows to prevent metabolic disorders. For the experiment, two groups of Ukrainian dairy black-and-white breed cows were formed, 10 animals per group. The experiment lasted 3 weeks prepartum and 3 weeks postpartum. Animals received a balanced diet, which consisted of haylage, silage, barley, wheat, corn, soybean meal, salt, mineral and vitamin premix. The first group was the control. To the diet of second group 300 mg of α-tocopherol acetate (0.6 g of Rovimix E-50) and 1 g/kg of dry hop cones per kg of dry matter was added. Before calving, the tested feed additive reduced the concentration of peroxide oxidation products in the cows blood (P<0.05) without affecting other parameters. Changes that are more significant detected after calving. A decrease in the concentration of lipid hydroperoxides (P<0.05), TBARS (P<0.05), and beta-hydroxybutyrate (P<0.05) were observed in the blood of the cows of the experimental group. Therefore, the addition into diet of transition cows of α-tocopherol and hop cones inhibits the lipid peroxidation and reduces the ketones formation. So, this feed supplement can be used to prevent ketosis and steatosis in cows.

The feasibility of using the complex mineral and vitamin feed additive “Nadezhda” in the rations of lactating first-calf heifers of Black-and-White breed has been examined in the article. It has been established that feed contain a low content of elements such as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc and cobalt. The ratio of nutrients and minerals, the degree of their availability for assimilation by the body does not provide their need. The use of the complex mineral and vitamin feed additive contributed to an increase in the milk productivity of first-calf heifers and the quality of milk, feed consumption per unit of production. All tested recipes of the complex mineral and vitamin feed additive, which have different versions of macro-, microelements and vitamins in their composition had a positive effect on the metabolic processes in the body of animals. For the production of 1 kg of milk in the experimental groups of cows less metabolic energy was spent by 5,09 (P < 0,05) and 8,06 % (P < 0,05), respectively, raw protein by 5,19 and 8,19 % (P < 0,05), digestible protein by 5,12 (P < 0,05) and 8,15 % (P < 0,05) compared with the animals of the control group. At the same time from the cows of the 1st experimental group have been received more milk by 151,6 kg in the amount of 2489 rubles, from the 2nd experimental group by 250,6 kg of milk in the amount of 4248,0 rubles. The prime cost of production of 1 kg of milk in cows of the 1st experimental group in comparison with the animals of the control group decreased by 0,72 rubles, and the 2nd experimental group by 1,21 rubles. The level of profitability of milk production in cows have been fed with additive recipe No. 1, in comparison with the animals of the control group increased by 3,71 abs.%, recipe No. 2 by 9,91 abs.%.

It is known that mineral additives play an important role in increasing the productivity and efficiency of the animal husbanry industry as a whole. The state of the body can be assessed by the content of mineral substances in a blood test. The purpose of the work was to study changes in morphological and biochemical blood parameters in first-calf heifers during the period of increasing the milk yield when they are fed a complex mineral and vitamin feed additive (CMVFA). The study of the influence of feeding the complex mineral and vitamin feed additive in the ration to first-calf heifers during the the period of increasing the milk yield on morphological and biochemical blood parameters has been carried out. The experiments were carried out in 2019–2020 in the OOO Breeding Farm “Valiev” in the Dyurtyulinsky district in the Republic of Bashkortostan on 3 groups of first-calf heifers of Black-and-White breed per 15 heads in each selected by the method of pairs of analogues. The animals of the control group received the main ration (MR) adopted on the farm, the 1st experimental group MR+120 g/head CMVFA according to the recipe No. 1, the 2nd experimental group MR+120 g/head CMVFA according to the recipe No. 2. In the ration of animals of the control group there was a deficiency of basic macro- and microelements. The use of CMVFA as part of the ration of first-calf heifers during the period of increasing the milk yield had a positive effect on the morphological and biochemical parameters of blood. Studies have shown that the use of CMVFA in the rations of first-calf heifers provided the need for minerals and vitamins, accelerating metabolic processes in the body during the most stressful period of lactation, the period of increasing the milk yield. According to the results of biochemical blood parameters, it is possible to esimate the improvement of protein, carbohydrate and mineral and vitamin nutrition in the first-cakf heifers of the experimental groups during the period of increasing the milk yield, which showed their genetic potential more fully and used nutrients more effectively for milk synthesis.

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.

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

The effectiveness of dairy cattle breeding largely depends on the intensity of use of the breeding stock. At the same time, the factor of the duration of economic use of animals is gaining importance, which affects not only the production economy, but also the improvement of stocks and breeds. The lifelong productivity, the quantitative and qualitative growth of the stock, the amount of capital investment in its formation and the efficiency of operation depend on the term for the productive use of cows. The terms of breeding and production use of animals are direct linked with the biologically possible longevity of each animal, in turn, the duration of the productive period of cattle is in the range of 12-17 lactations. The influence of feed on production is associated primarily with the level of digestion and assimilation. The digestive capacity of the digestive tract of animals can be improved by selecting the optimal ratio in the diet of rough, juicy and concentrated feeds, i.e. optimization of animal feeding types. We conducted an analysis of milk productivity in lactating cows, when using AVMC feed additive in the diet. The experiment was conducted in the conditions of the dairy farm of Biryuli CJSC of the Vysokogorsky District of the Republic of Tatarstan on three groups of lactating cows. For the experiment, 30 cows were selected, 10 in each Holstein black-and-white breed according to the principle of analogues. Studies have shown that AVMC with rapeseed oil seeds and AVMC with fus in the diet of lactating cows provided higher animal productivity and positively affected the chemical composition of milk.

The antioxidant drug "E-selenium" was used to reduce the processes of LPO in the body of fresh cows. Two groups were formed from the analogous cows of the black-and-white breed: The Control was intact, Experienced received the antioxidant drug injection at a dose of 10 ml at the rate of 1 ml per 50 kg of live weight per head for 4 months of lactation from the second. The diets of animals of all groups were the same, balanced in nutrients and met the standards of the RAAS. The duration of the experiment was 150 days. During the period from the 3rd to the 5th month of lactation, there was a positive dynamic in increasing the number of fat globules in the milk of cows of the Experimental group. By the end of the 4th month, it was higher than the Control by 8.9 %. This confirms the active effect of the drug "E-selenium", which contributes to a positive dynamic in increasing the size of fat globules. Non-enzymatic antioxidant tocopherol is an active element of the anti-oxidative system. Selenium stimu-lates the body's own antioxidant system. In both experimental groups, the relationship between the concentration of peroxidation products and the quantitative composition of fat globules and their size was established. In the milk of cows of the Experimental group, the oxidation processes were inhibited by neutralizing the products (POL), increasing the number of large fat globules and the total fat content in the milk.

The organization of feeding of highly productive cows is one of the most difficult tasks in dairy cattle breeding. The purpose of the work was to study the influence of natural mineral additive on the productivity, composition and some technological qualities of milk of cows of Black-and-White breed of Ural type. Research and production experiment has been carried out in CJSC “Glinki” in the Ketovsky district in the Kurgan region on Black-and-White cows. The influence of bentonite additive in the ration of highly productive cows during the period of increasing the milk yield on the composition and technological quality of milk and dairy products has been determined. In general, for the first 100 days of lactation the cows of the experimental group have produced by 191 kg more natural fat milk or 8,4 %, compared to the control group. In terms of 4 % milk from animals of the experimental group has been got by 233 kg or 9,3 % more than of the control group. The yield of milk fat in the experimental group was by 10,44 kg or 12,9 % more than the control group. The difference in milk protein yield for 100 days of lactation was 7,34 kg or 9,8 %. The economic indicators (prime-cost, profitability) of milk production when feeding the mineral additive bentonite to cows have been calculated. With an increase in the total cost of obtaining milk from cows of the experimental group, caused by higher milk yields and the purchase of bentonite, the revenue from the sale of milk from this group was by 7,83 thousand rubles or 8,4 % more. As a result, milk production from animals of the experimental group was by 3,44 % more efficient. It has been found that the inclusion of bentonite in the composition of concentrated feed in the amount of 400 g/head/day allowed to reduce their expenditure, as well as EFU and digestible protein, which ultimately provided a higher level of profitability of milk production.

Изучен способ нормализации обменных процессов и повышения продуктивности молочных коров при использовании комплекса биологически активных веществ. Эксперимент проведен на коровах голштинской породы (n=12) с продуктивностью за предыдущую лактацию 9000 кг молока. За 20 дней до отела и в течение 65 дней после коровы опытной группы получали комплексную кормовую добавку (ККД), включающую минерал шунгит, холин в «защищенной» форме, пробиотик «Целлобактерин+» и жмых льняной, в количестве 200 г на голову в сутки в смеси с концентратами. Для изучения обменных процессов в организме коров (n=5) в конце опыта отобраны пробы крови и определены основные биохимические показатели. Для оценки продуктивных качеств проводили контрольные дойки. Отмечено повышение в крови коров опытной группы концентрации общего белка на 2,8%, глюкозы — на 26,8% (P≤0,01), фосфолипидов — на 15,2% (P≤0,05), снижение мочевины на 23,6% (P≤0,05), билирубина — на 23,8% (P≤0,01), активности АЛТ на 13,11 (P≤0,05), АСТ — на 14,6% (P≤0,05). Использование ККД позволило снизить и привести в норму активность ферментов: лактатдегидрогеназы (ЛДГ), гаммаглутаминтрансферазы (ГГТ), креатинкиназы. Повышение интенсивности обменных процессов и нормализация показателей, характеризующих работу печени с использованием в питании комплекса биологически активных веществ ферментно-пробиотического, антиоксидантного и липотропно-гепатопротекторного действия, привело к повышению молочной продуктивности. A method of normalizing metabolic processes and increasing the productivity of dairy cows using a complex of biologically active substances has been studied. The experiment was carried out on Holstein cows (n = 12) with a productivity for the previous lactation of 9000 kg of milk. 20 days before calving and within 65 days after the cows of the experimental group received a complex feed supplement (CFS), including the mineral shungite, choline in a "protected" form, the probiotic "Cellobacterin +" and flaxseed cake, in an amount of 200 g per head per day mixed with concentrates. To study metabolic processes in the body of cows (n = 5), at the end of the experiment, blood samples were taken and the main biochemical parameters were determined. To assess the productive qualities, control milking was carried out. An increase in the blood of cows of the experimental group was noted in the concentration of total protein by 2.8%, glucose - by 26.8% (P≤0.01), phospholipids — by 15.2% (P≤0.05), a decrease in urea by 23,6% (P≤0.05), bilirubin - by 23.8% (P≤0.01), ALT activity by 13.11 (P≤0.05), AST — by 14.6% (P≤ 0.05). The use of CFS made it possible to reduce and normalize the activity of enzymes: lactate dehydrogenase (LDH), gamma glutamine transferase (GGT), creatine kinase. An increase in the intensity of metabolic processes and the normalization of indicators characterizing the work of the liver with the use of a complex of biologically active substances of enzymatic-probiotic, antioxidant and lipotropic-hepatoprotective action in the diet led to an increase in milk productivity.

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%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.
