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.

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.%.

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 physiological state of animals is to a certain extent characterized by hematological indicators, since blood occupies a special place in the body. By transferring nutrients and biologically active substances, the blood performs the general regulation of vital functions of the body. The use of Vitartil as a feed additive in the diets of animals leads to an increase in glycolytic processes and a decrease in the body’s need for oxygen delivery, which contributes to the growth of the animal body. The purpose of the research was to study the changes in blood parameters taking into account the age of Hereford steers against the background of the use of Vitartil feed additive to the main diet and its effect on the productive traits of animals. In order to carry out the experiment two groups of steers-analogs of Hereford breed have been formed at the age of 6 months per 10 heads in each. The difference between the groups was that the steers of the experimental group have been received the feed additive Vitartil in addition to the main diet. The greater yield of the meat part was in the steers of the experimental group in comparison with the herdmates of the control group. This indicator in the experimental group was 78,9 %, while in the control group it was lower by 1,6 %. The animals of the experimental group were superior to their herdmates in terms of meat weight by 1,4 kg or by 8,8 %. The relative number of bones was lower in the experimental group and amounted to 18,4 %, and in the control group 19,2 %. The meat content index was high in the steer have been received the biologically active additive Vitartil and was 4,3, and in the control group 4,0. It has been found that the use of Vitartil feed additive to the main diet of Hereford steers increases the blood content of hemoglobin and glucose, which has a certain effect on the morphological and chemical composition of meat, as well as increases its energy value.

Primary changes in the physiological status of animals can be traced in the deviation from the norm of indicators of a number of substances in biological fl uids, since biochemical indicators are a kind of indicator of processes occurring in the body. Having knowledge of hematological changes in the body of cattle, managers and specialists of livestock farms can manage the productivity and health of highly productive animals. The purpose of the research was to determine and analyze the biochemical parameters of the blood of cows in the dry period and at the increasing the milk yield when wet crushed corn grain was introduced into their ration. The research has been carried out on cows of Black-and-White breed in LLC “Agrofi rma “Urozhai” in the Zonal district in the Altai Territory. During the research the prevalence of productivity indicators of cows of the experimental group over analogues from the control group was proved. Thus average daily milk yield for the accounting period (60 days) it was 30,9 kg, which was 5,2 kg more than the control herdmates (P > 0,95). The total productivity of one head was 1541,57 kg of milk in the control group and 1854,69 kg in the experimental group, which was 313,12 kg more (P > 0,95). It has been found that most of the studied biochemical parameters corresponded to the physiological norm. The exception was the increased content of total protein in the blood of lactating cows of the experimental group 5 g/l above the upper limit of the norm (P > 0,999). A low albumin content in the blood of animals of the experimental group has been noted, and this indicator was signifi cantly lower than that in the control group by 3,45 g/l (P > 0,99). An excess of the physiological norm of globulin in the blood of animals of both groups has been found, the indicators of the experimental group signifi cantly exceeded the control group by 9,5 g/l (P > 0,99). There was a low level of chlorides after the increasing the milk yield 88,1 mmol/l in the control group and 89,2 mmol/l in the experimental group, then excess of manganese after the increasing the milk yield was 4,50 mmol/l in the control group and 8,14 mmol/l in the experimental group, which could be associated with the increased content of this element in feed and soil.

The effect of aqueous extract of pine needles, pine nut shells and arabinogalactan on the metabolism of dairy cows was studied. The objectives of the research were to investigate the elemental composition of aqueous extract of pine needles, pine nut shells and arabinogalactan and to study the effect of cows’ feeding on aqueous extract containing these supplements on the biochemical parameters of blood, physical and biochemical parameters of cows’ urine. The experiment was carried out in theKrasnoyarskTerritoryon black-and-white cows at the age of fi calving with an average body condition and life weight of 580-600 kg. Two groups of cows were formed, 10 animals in each. The duration of the experiment was 100 days. The cows were kept tied, in year-round stalls, milking was carried out automatically into the milk pipe. According to the scheme of the experiment, the control group was fed on the main diet, the experimental group was given aqueous extract (200 ml/head/day) of pine needles (15 g/l), pine nut shells (25 g/l) and arabinogalactan (25 g/l) in addition to the main diet. The test infusion was fed in a mixture with concentrated feed. The feeding ration corresponded to the zootechnical standards. It was found that feeding cows on aqueous extract of the studied forest components did not have a negative eff on the metabolism in the body of the animals: the biochemical parameters of blood and the physicochemical parameters of cows’ urine corresponded to the norm of healthy animals. At the same time, metabolic processes in the blood of the cows in the experimental group were very intensive, mineral and carbohydrate metabolism improved, as evidenced by an increase in glucose content by 16.6%, iron – by 17.8, phosphorus – by 13.0%.

The results of the evaluation of the effect of alfalfa haylage harvested with preservatives on the efficacy of bioconversion of nutrients and energy rations in meat products. Scientific and economic experience held in the SEC-farm «Alga» Chekmagushevsky district of the Republic of Bashkortostan. There are three trench silage from alfalfa. In one of them the food was laid with the application of the preservative Laxil, the second – and third Silostan – no preservatives. Laxil preservative was added at the rate of 1 liter per 15 tons of green mass, Silostan – 1 liter to 150 tons. The object of research was 45 bulls of black-and-white breed at the age of 9 months, of which three groups were formed: control and two experienced. Gobies control group received silage of alfalfa harvested without preservatives, and the animals of I and II experimental groups – silage, preserved by Laxil and Silostan. For studying of meat productivity and quality of meat of test bulls control slaughter of 3 bulls from each group was carried out. The results of the study indicate the superiority of calves of the experimental group over their counterparts from the control groups both in vivo and post-slaughter parameters. The results of the evaluation of the transformation of protein and energy feed in the production of bulls compared groups when grown for meat indicate that in the body of young I and II experimental groups were deposited a little more protein compared with peers from the control group.

Currently it has become popular to use different feed additives that allow us to increase the indicators of live weight gain by accelerating the metabolic processes in the body of animals, which allows us to take everything from the feed and to the maximum. With the advent of this trend in the market the range of feed additives in different directions has increased. For the research we have selected Vermiculite Expanded as a feed additive. The purpose of the research was to search the dynamics of changes in blood parameters in experimental steers in comparison with the control group against the background of the use of the feed additive Vermiculite Expanded. An assessment of blood parameters of Kazakh White-headed steers against the background of the use of mineral feed additive has been presented in the article. Three groups of steers have been formed for the research: the 1st group has been as a control and received the main economic ration; the 2nd and 3rd experimental groups received the feed additive to the main feeding ration in doses of 10 and 15 g/head for the groups, respectively. On the laboratory base blood tests we were able to search the correlation between morphological and biochemical parameters of blood and the growth rate of experimental steers. The steers of the 2nd and 3rd groups during the experiment had an advantage in blood serum indicators in terms of both total lipids and glucose, in the end, the difference in percentage ratio with the control group was 14,08 % in the 2nd group and 12,60 % in the 3rd experimental group. It is worth noting that the concentration of phosphorus and calcium in the blood was at the high level, which in our opinion reflects the influence of the feed additive Vermiculite Expanded.

There is a need to develop more rational technologies for rearing and fattening steers by adjusting the rations taking into account the technological features of rearing animals in this natural zone and the genetic characteristics of specific animal breeds under the modern conditions of the market economy in order to obtain high-quality products from livestock enterprises with intensive production rates. The purpose of the research was to study the influence of the feed additive expanded vermiculite on the nature of the course of lipid metabolism in steers of Kazakh White-headed breed during fattening. The experimental part of the work was performed in Terra LLP, which is located in the village of Nadezhdinka in the Karabalyksky district in the Kostanay region in the Republic of Kazakhstan. We have found the following differences in the experimental groups: in the period from 6 to 9 months of age the total lipid concentration index increased by 19 % in the control group, by 29 % in the 2nd experimental group, and by 35 % in the 3rd experimental group. This indicates the positive influence of the feed additive on the steers of the experimental groups. When the concentration of this indicator decreased in the subsequent age period, the percentage ratio between the groups remained until the age of 15 months. The mineral feed additive expanded vermiculite had the favorable influence on the growth of live weight in the experimental groups by an average of 15 % per head compared to the control group, the highest increase in live weight was observed in the 3rd experimental group, which was given the additive of 15 g/head. Therefore, the amount of drug intake in the body directly affects its positive effect on the physiological status of the animal body.

The expediency of using the probiotic drug Biolax-U in the rations of lactating and dry cows of Black-and-White breed has been studied and scientifically proved. The influence of this drug on the morphological and biochemical parameters of animal blood has been determined. The composition of the probiotic drug Biolax-U consists of eight strains of a balanced complex of living lactic acid bacteria, yeast and actinomycetes, as well as biologically active substances. For experimental studies conducted on 2 groups of cows have been selected by the method of pairs-analogs, the influence of feeding of feed have been prepared with the use of the microbiological drug with probiotic action Biolax-U on feed consumption, morphological and biochemical changes in blood has been studied. Analysis of the rations of cows indicates that the content of calcium, phosphorus, magnesium, sulfur and trace elements such as manganese, copper, zinc and cobalt in the feed has been reduced. It has been found by studies that the use of probiotic drug Biolax-U had the positive influence on the feed intake, digestibility and better assimilation of feed nutrients and contributed to the improvement of blood morphological and biochemical parameters. For example, in animals of the experimental group hemoglobin has increased by 3,6 % (Р < 0,05), red blood cells by 10,1 (P ≤ 0,05), the content of leukocytes by 4,43, carotene by 9,6, glucose by 3,4; reserve alkalinity by 15,6, calcium by 19,4 (P ≤ 0,01), and phosphorus by 18,4 % compared with the control group of animals. During the lactation significantly improved hematological parameters including alkalinity reserve by 5,11 %, calcium level by 11,1, phosphorus by 8,6, hemoglobin by 14,2 %, the content of erythrocytes by 12,3, leukocyte by 3,86, and carotene 11,1 % against the parameters of animals of control group. The improvement of morphological and biochemical parameters of blood of cows indicates about stimulating effect on hematopoiesis and the general clinical condition of animals that contributes to the improvement of metabolic processes when using feed prepared with the use of microbiological drug with probiotic action Biolax-U.
