For successful denitrification in the body of dairy cattle in zootechnical practice are widely used feed additives with adsorption and antioxidant properties, which, linking nitrates and nitrites in the digestive system, are able to effectively eliminate these toxic compounds in the body. The aim of the research was to study the effect of the adsorbent ekosil and the antioxidant Hadox on the digestibility and digestibility of the nutrients of the diet of lactating cows with a subtoxic dose of nitrates in feed. This article presents the results of studies showing that to increase the milk productivity of dairy cows in diets with a subtoxic dose of nitrates, it is advisable to include ecoosil adsorbent in a dose of 4 kg / ton of feed and an antioxidant Hadox dose of 125 g / ton of feed. It was established that joint approved drugs contributed to the intensification of the processes of digestive metabolism by optimizing the denitrification reaction. This resulted in a significant (P <0.05) increase in dairy cattle 3 of the experimental group versus a control group of dry matter digestibility by 3.28, organic matter by 3.22 %, crude protein by 3.52 %, crude fiber - by 3.07 % and BEV - by 3.25 %. Due to better denitrification under the joint effect of Ecosil and Hadox preparations in animals 3 of the experimental group, the digestibility of raw protein in the ration was optimized, which, against the control group, showed a significant (P <0.05) increase in the amount of nitrogen excreted in milk by 9.34 % and daily the deposition of this element in the body - by 51.43 %. Due to the synergism of the action of the adsorbent and antioxidant in milk of dairy cattle 3 of the experimental group, during the day, there was a significant (P <0.05) more calcium and phosphorus or it was postponed during the same time in the body more of these macronutrients than in the control.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Для получения препаратов и добавок, обладающих антиоксидантными свойствами, представляют интерес выжимки томатов, образующиеся при производстве сока прямого отжима с предварительным отделением семян. Проведена сравнительная оценка эффективности функциональных свойств образцов пищевой добавки, полученных из выжимок томатов по различным технологиям: образец добавки 1 получен по технологии, включающей ИК-сушку выжимок, их охлаждение и измельчение; образец добавки 2 – по инновационной технологии, включающей дополнительную предварительную обработку выжимок в ЭМП СВЧ перед ИК-сушкой. Исследования проводили в течение 30 дней на трех группах лабораторных белых крыс: контрольной, животные которой получали стандартный рацион, и двух опытных, в которых животные помимо основного рациона получали при кормлении индивидуально 1 раз в сутки 2 г добавки образца 1 (1-я опытная группа) или образца 2 (2-я опытная группа). Установлено, что степень снижения концентрации ферментов печени АсАт и АлАт в крови животных 2-й опытной группы соответственно на 10,6 и 11,0% выше, чем в крови животных 1-й опытной группы. Степень снижения содержания диеновых коньюгатов, кетодиенов и малонового диальдегида в крови животных 2-й опытной группы была соответственно на 22,1; 10,1 и 12,7% выше по сравнению с аналогичными показателями животных 1-й опытной группы. Таким образом, доказано, что пищевая добавка «Томатная», выработанная по инновационной технологии, проявляет ярко выраженные антиоксидантные и гепатопротекторные свойства, что обеспечивает нормализацию биохимических процессов в организме, повышает его антиоксидантную защиту и препятствует разрушению мембран клеток. For the obtaining of preparations and additives with antioxidant properties, tomato pomace, formed during the production of direct-pressed juice with preliminary separation of seeds, is of interest. A comparative evaluation of the effectiveness of the functional properties of food additive samples obtained from tomato pomace using various technologies was carried out. The sample of additive 1 was obtained using a technology that includes IR drying of pomace, cooling and grinding; the sample of additive 2 was obtained using a technology that includes additional pretreatment of pomace in microwave EMF before IR drying. The studies were carried out for 30 days on three groups of laboratory white rats: a control group, the animals of which were given a standard diet, and two experimental ones, in which the animals, in addition to the main diet, were given individually once a day with 2 g of an additive of sample 1 (1st experimental group) or sample 2 (2nd experimental group). It was found that the degree of decrease in the concentration of liver enzymes AsAt and AlAt in the blood of animals of the 2nd experimental group was respectively 10,6 and 11,0% higher, than in the blood of animals of the 1st experimental group. The degree of decrease in the content of diene conjugates, ketodienes and malondialdehyde in the blood of animals of the 2nd experimental group was higher respectively by 22,1; 10,1 and 12,7% compared with similar indicators of animals of the 1st experimental group. Thus, it is proved that the food additive «Tomatnaya», developed by innovative technology, shows pronounced antioxidant and hepatoprotective properties, which ensures the normalization of biochemical processes in the body, increases its antioxidant protection and prevents the destruction of cell membranes.

Scientific publications describe the positive effect of feed additives and pharmacological complexes on metabolic processes in the body of broiler chickens, in particular, on the protein composition of the blood, meat productivity and protein accumulation in meat. The Peak-Antistress feed additive developed at the Department of Morphology, Physiology and Pharmacology of the South Ural State Agrarian University allows to reduce the technological load on the poultry body by stimulating the general metabolism and complex antioxidant action. Experiments on the use of the feed additive Peak-Antistress were carried out on broiler chickens of the final hybrid of the Arbor Acres cross in an industrial-type poultry farm with floor technology. The poultry was divided into three groups of 6,000 chickens each and kept in one workshop in separate sections. The control group received the main diet, the 1st experimental group received the main diet and feed additive at a dose of 1269 g / t of feed 5 days before slaughter, the 2nd experimental group received the main diet and feed additive at a dose of 1693 g / t of feed 5 days before slaughter. Slaughter of broiler chickens was carried out according to the technological instructions of the enterprise on the 38th day. Against the background of the use of the feed additive in the experimental groups of broiler chickens, stimulation of protein metabolism was observed, as evidenced by an increase in total protein in the blood by 7.9–20.1%, an increase in the level of protein in white meat by 0.1–0.3%, and a tendency to an increase in amino acids in white meat protein by 0.2–12.3%.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

Aim. The effectiveness of the use of the mineral feed additive bischofit in the diets of young sheep in the South of Russia at various doses and its impact on the productive qualities of young sheep. Materials and Methods. The material for conducting the experiment in this household was the livestock of sheep of the Grozny breed on fattening. The sheep of the control group received a basic household diet, the I experimental group received 5 ml of bischofite per head per day in addition to the main diet, the II experimental group received 8 ml of feed additive. Classical zootechnical methods were used in the process of work, including wool yield and physical and technological properties were studied individually in 3 experimental animals from each group according to the VNIIOK method. The research materials were processed by the methods of variation statistics using the Microsoft Office software package. Results. Young sheep from the I experimental group, who received bischofite at 5 ml / head per day, were 9.4% more in live weight than in the control group. Young sheep that received 5 ml of feed additive had the best meat index, and exceeded the control group in terms of pulp yield by 12.5%. The maximum deviation from the average value of the cut of pure wool in the upward direction (110.6%) was observed in I experimental group. The most durable wool of 7.24 sN / tex is found in the group that received the bischofit feed additive as part of the main diet. Conclusion. To compensate for the lack of mineral substances of the natural and environmentally safe feed additive bischofit at a dose of 5 ml / head per day, it changes the metabolic reactions in the body in a positive way, which is confirmed by an increase in the growth of live weight and wool productivity.

В научной работе изучена эффективность профилактики внутренних незаразных болезней в послеродовом периоде у коров путем введения в рацион глубоко сухостойных коров кормовой добавки «Кауфит драй плюс». Эффективность кормовой добавки оценивали, анализируя частоту встречаемости незаразной патологии, данные физикального осмотра, морфологические и биохимические изменения в крови, рН-мочи и рубцовой жидкости. Исследования проводились на двух группах аналогов глубоко сухостойных коров (контрольная и опытная). Было установлено, что на 21-й день после отела в опытной группе по сравнению с контролем достоверно уменьшилась частота встречаемости: задержания последа на 11,7%, послеродового эндометрита на 10,0%, родильного пареза на 8,3%, клинического мастита на 8,4%. Однако случаи заболевания смещения сычуга за исследуемый период в опытной группе увеличились на 1,6%, кетоза – на 3,3%, гипотонии рубца – на 3,3%, асептических болезней копыт – на 4,9%. В опытной группе отмечено достоверное повышение кислотности рубцовой жидкости (с 6,82±0,38 до 5,41±0,24, р<0,01) и мочи (с 8,23±0,18 до 6,53±0,12, p<0,01); произошло достоверное снижение уровня глюкозы на 39,4% (p<0,01), увеличение содержания кетоновых тел в 2,8 раза, повышение уровня кальция и фосфора на 22,4 и 18,2% (p<0,05) соответственно. Обнаруженные изменения в биохимическом профиле крови исследуемых коров свидетельствуют о развитии энергетического дефицита в организме коров опытной группы и развитии гипокальциемии в организме коров контрольной группы. Применение кормовой добавки «Кауфит Драй плюс» достоверно снижает риск развития гипокальциемии, родильного пареза, послеродового эндометрита, задержания последа и клинического мастита, но увеличивает риск развития таких болезней в послеродовом периоде как гипотония рубца, кетоз, смещение сычуга, асептических болезней копыт. The effectiveness of prevention of internal non-contagious diseases in the postpartum period in cows due to the introduction of a feed additive "Kaufit dry plus" into the diet of deeply dry cows was studied in the scientific work. The effectiveness of the feed additive was evaluated by analyzing the incidence of non-infectious pathology, physical examination data, morphological and biochemical changes in blood, pH-urine and scar fluid. The studies were carried out on two groups of analogues of deeply dry cows (control and experimental). It was determined that on 21 days after calving in the experimental group, compared with the control, the incidence of retention of the afterbirth significantly decreased by 11.7%, postpartum endometritis by 10.0%, puerperal paresis by 8.3%, clinical mastitis by 8.4%. However, cases of abomasal displacement during the study period in the experimental group increased by 1.6%, ketosis - by 3.3%, scar hypotension - by 3.3%, aseptic hoof diseases-by 4.9%. In the experimental group, there was a significant increase in the acidity of scar fluid (from 6.82±0.38 to 5.41±0.24, p<0.01) and urine (from 8.23±0.18 to 6.53±0.12, p<0.01); there was a significant decrease in glucose by 39.4 % (p<0.01), an increase in the content of ketone bodies by 2.8 times, an increase in calcium and phosphorus by 22.4% and 18.2% (p<0.05), respectively. The detected changes in the biochemical profile of the blood of the studied cows indicate the development of energy deficiency in the body of cows of the experimental group and the development of hypocalcemia in the body of cows of the control group. The use of the feed additive "Kaufit dry plus" significantly reduces the risk of hypocalcemia, puerperal paresis, postpartum endometritis, retention of the afterbirth and clinical mastitis, but increases the risk of such diseases in the postpartum period as hypotension of the scar, ketosis, displacement of the rennet, aseptic diseases of the hooves.

This article presents the results of studies conducted on piglets with the inclusion of natural feed additives in the diet in order to prevent and correct metabolism. The first experimental group of piglets received a total diet consisting of fullfledged compound feed, a complex micro-feed product consisting of blue-green algae Spirulina, dihydroquercetin and organic iodine, the second experimental group additionally received Spirulina and dihydroquercetin. The introduction of these natural feed additives into the diet of piglets helped to increase the adaptive ability , correction and prevention of metabolic disorders in the body. In these studies, dacha feed supplements prevented hyperbilirubinemia. As a result, the concentration of total bilirubin in the blood serum of pigs of the first experimental group was 1% lower, in the second experimental group it was 13,7% lower than in the control group. They also had a positive effect on the functional state of the liver, as evidenced by a lower content of AlAT and AsAT activity in the blood serum compared to those in piglets of the control group with a close cholesterol-forming fraction. The animals of the experimental group were less ill and the safety of this group was 100%, in the control group it was 90%. The average daily increase in live weight of pigs for 90 days in the first experimental group was 1% higher than in the control group, and in the second experimental group it was 21,7% higher.

Promising direction in ensuring food security and independence of Russia is the widespread use and study of new feed additives of probiotic action. Today, probiotic preparations are widely used in dairy farming. They support the positive microbial balance of the gastrointestinal tract and stimulate the activity of the digestive, motor-evacuation, hormonal and immune systems. Authors studied the efficiency of the composition of 2 strains of Bacillus subtilis during 14 days after calving (1 experimental group) and 14 days before calving and 14 days after calving (2 experimental group) in the technology of milk production and improving its quality. In the process of conducting scientific and industrial experience, modern research methods were used that were able to obtain high-quality and most informative data on the processes occurring in the body. Analysis of the results of hematological blood parameters of animals of all groups confirmed the physiological of recovery of the cow's body in the postpartum period, but with different degrees of intensity. Animals of the experimental groups reached peak milk production. By the end of the third month in group 1, milk productivity was 28.94±6.84 kg, in group 2 - 32.17±3.33 kg, which formed an increase of 6.44% and 15.59% relative to the background values. In the control group of cows-27.90±7.25 kg. By day 150, the average daily milk yield in animals of the first group was 25.07 ± 4.38 kg, the second - 25.33 ± 2.52 kg, control 22.75 ± 8.82 kg. Milk quality indicators - fat and protein content in animals receiving probiotic supplements were variable. In the milk of animals of the 1st and 2nd groups, the average fat content was recorded 3.69 g / 100g and 3.74 g / 100g, respectively, and the average protein content was 3.104 g / 100 g and 3.240 g / 100 g. In peers of the control group, the fat and protein content in milk was determined to be 3.79 g / 100 g and 3.016 g / 100 g. The studies established and proved the promise of the widespread introduction of probiotic in dairy cattle breeding, which was based on the composition of endo- and exometabolites of 2 strains of Bacillus subtilis. There was an improvement in the physiological status and an increase in the milk productivity of Holstein cows of the black-motley breed.
