The article discusses the results of a study of the effect of the use of biostimulants Biosvet made by the Filatov method from plant materials of foreign origin, and Megasvet made by the same method from domestic plants on the productivity and quality indicators of milk of Ukrainian black-and-white cows. For the study 30 cows with a productivity of 5000 - 5500 kg of milk per lactation were selected, which were divided into three groups of 10 animals each. The cows of the control group (C-1) in order to prevent the effects of stress from injections were injected subcutaneously in the neck with a physical solution in an amount of 15 m. The cows of the first experimental group (E-1) were injected with the biological product Biosvet 15 ml each, and the cows of the second experimental group (E-2) received the biostimulator Megasvet developed by us in the same amount. Four periods were identified in accordance with the season: autumn, spring, summer and autumn, Injections were given at the beginning of each period, Milk productivity and quality indicators were determined every ten days. The experience lasted from September 2020 to August 2021. As a result of the study it was proved that the use of biostimulants made from raw materials of plant origin has a positive effect on both productivity and quality indicators of milk in cows of the Ukrainian dairy black-and-white breed. The results of the use of biostimulants prove the higher efficiency of the biological product Megasvet in comparison with the biological product Biosvet. The use of Megasvet provides an increase in the productivity of cows in comparison with the use of Biosvet in the range from 5.72 % to 7.02 %, depending on the period of the year. On average per year the daily productivity in the second experimental group of cows, where Megaslight was used made up 6.35%. It was higher than in the first experimental group, where Biosvet was used. The use of Megasvet was more effective than Biosvet and in determining the quality indicators of milk, namely: fat content the presence of milk fat and protein content in milk.

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.

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 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.

It is known that one of the most important reasons for the birth of weak calves is the impact of adverse factors on the physiological status of the cow, which in turn affects the intrauterine and postnatal development of the fetus and newborn. The results of studying the introduction of different doses of tissue biostimulator to cows during the dry period and its effect on the development of the conformation of calves received from them have been presented in the article. The experiment was carried out in 2019 on cows of Priobsky type of Black-and-White breed and calves obtained from them. In order to conduct the experiment four groups of dry cows-analogs have been formed with 10 heads in each for 55–60 days before the expected calving at the age of III lactation and older. When selecting animals the live weight and milk productivity of cows for the previous lactation have been taken into account. The highest growth rate has been observed in calves from cows the 2nd experimental group, which exceeded the control by 24,4 % (P ≤ 0,001). The best indicators of conformation development have been also observed in calves obtained from cows of the 2nd experimental group, which were injected subcutaneously with 22,5 ml of tissue preparation. So, oblique body length have been greater by 12,6 % (P ≤ 0,001), chest girth by 17,3 % (P ≤ 0,001), width of hook bones by 21,0 % (P ≤ 0,01), the width of the pin bones by 15,0 % (P ≤ 0,05). The lengthiness index was by 11,5 % higher (P ≤ 0,001), the blockiness index was by 4,1 % higher (P ≤ 0,05), and the boniness index was by 10,6 % lower (P ≤ 0,05) than in the control group herdmates.

Summary. Practical interest at the present stage in feeding highly productive cows is the use of fl axseed and rapeseed press cakes, which are sources of energy, high-grade protein and polyunsaturated fatty acids. Rapeseed and linseed press cakes are excellent protein feed for cattle. In concentrates for this animal species they may be the only high-protein components. The purpose of the work was to carry out comprehensive research on fi rst-calf heifers productivity traits, milk quality and its technological properties when using linseed and rapeseed press cakes in their rations. The research has been carried out in JSC “Uchkhoz Iyulskoe of Izhevsk State Agricultural Academy”. The object of research was fi rst-calf heifers of Black-and-White breed. In order to conduct research, four groups of fi rst-calf heifers have been formed – a control group and three experimental groups of 12 animals in each group. A comprehensive evaluation of productive traits, milk quality, its technological properties, as well as the quality of dairy products (cheese, cottage cheese, yogurt) when used in fi rst-calf heifers feeding various cakes (linseed and rapeseed). The lowest prime-cost of 1 kg of milk has been obtained with the simultaneous use of linseed and rapeseed cakes of 14,0 rubles, which was less than in the control group by 2,1 rubles, the 1st experimental group by 1,7 rubles and the 2nd experimental group by 0,7 rubles. The largest gross profi t from milk sales has been received in the 3rd and 2nd experimental groups of 55 744 and 48 202 rubles, respectively. The level of profi tability in all groups was high and ranged from 36,6 % in the control group and up to 57,1 % in the 3rd experimental group. The result of the conducted researches has proved the effi ciency when feeding lactating fi rst-calf heifers of Black-and-White breed of rapeseed press cake and a mixture of rapeseed and linseed press cake in 1 : 1 ratio when replacing 30 % (on crude protein content) of sunfl ower press cake in their rations.

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 a research and production experiment carried out in the milk farm of «Klenovo-Chegodaevo» (Moscow) on two groups of holsteinized black-and-white cows with a milk yield of 7000 kg of milk per lactation, 20 heads each, it was found that an increase in the concentration of metabolic energy (CME) in the dry matter of the cows ration from 10,7 to 11,0 MJ/kg in the period from 21 to 120 days of lactation, due to the inclusion of protected fat in the diet of cows in the experimental group, in the amount of 300 g/head/day, produced on the basis of vegetable raw materials, contributed to an increase in milk yield of 4% fat and milk fat yield by 9,5% (p<0,05) for 120 days of lactation, while reducing feed costs for its production, expressed in CME by 5,4%. More intensive milking of cows in the experimental group in the new calving period had a positive effect on the tendency to increase milk yield of standard (4%) fat content and the yield of milk fat in general for 305 days of lactation by 7,4% (p>0,05), compared with control. Calculations of economic efficiency have shown that the use of fractionated fat in the amount of 300 g in the ration of high-yielding cows during the milking period from 10,7 to 11,0 MJ/kg can reduce the cost of 1 quintal of milk of base fat content (3,4%) produced by cows from the experimental group for the first 120 days of lactation by 43,6 rubles. or by 1.9% while receiving additional profit from its sale in comparison with the control in the amount of 3502,5 rubles. for 1 head. Biochemical studies of the blood of cows in the experimental groups, carried out on the 120th day of lactation, revealed a tendency for a more intense course of protein and lipid metabolism in the body of cows was revealed, who received a diet with an increased to 11,0 MJ/kg level of CME in dry matter of the diet, due to the use of protected vegetable fat in an amount of 300 g.
