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

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 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.

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.

Introduction. Nutrition has a great effect on the quality of life and longevity. Modern food industry pays much attention to the issue of obtaining high-quality and safe livestock products grown without feed antibiotics. The research objective was to study the effect of chamomile extract on a complex of economically useful traits of young rabbits and the qualitative characteristics of meat, as well as to determine the optimal dosage of chamomile extract. Study objects and methods. The experimental research was carried out on the animal farm of the Kuzbass State Agricultural Academy in 2018. Five experimental groups and one control group of young Californian rabbits were formed according to the principle of analogue pairs. Each group included 10 rabbits. From 70-day age, the animals of the experimental group I were supplemented with a phytobiotic feed additive based on wild chamomile extract at a dose of 0.5 g per rabbit per day. In experimental group II, each rabbit received 1 g per day; in experimental group III, it was 1.5 g per rabbit per day; in experimental group IV – 2.0 g per rabbit per day; in experimental group V – 2.5 g per head per day. The experiment lasted 30 days. Results and discussion. The best result was achieved in experimental group II. In the experimental groups, the rabbits demonstrated an increase in hemoglobin. The use of phytobiotic feed additives in the diet did not cause any pathological changes in internal organs. The average live weight at the end of the experiment, compared with the control group, was higher: experimental group I – by 0.82%, experimental group II – by 6.96%, experimental group III – by 5.01%, experimental group IV – by 3.73%, experimental group V – by 2.80% (P ˃ 0.01). An analysis of the chemical composition of rabbit meat after the experiment showed that the water content in the rabbit meat ranged from 76 to 77%, which suggests high water-holding properties. The high dietary qualities of the rabbit meat depended on the content of protein (20–22 wt%) and the low fat content (5–7%). These data make it possible to promote rabbit meat for dietary products. Conclusion. According to the slaughter indicators and the phytobiotic feed additives parameters of meat, the optimal dose of phytobiotic feed additives is 1 g per head per day.

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.

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.

To study the effect of different doses of feed additive TC VMP in the composition of complete feed granular feed on the digestibility of nutrients and retention of Nitrogen in young rabbits with intensive cultivation technology, a scientific and economic experiment was conducted. To carry out a balance experiment, four rabbits were selected from each group of test animals, which were placed individually in specially equipped cages. The experiment was performed by the method of groups in three periods: preparatory – 7 days, preliminary – 5 days, accounting – 6 days. Analysis of feed, feces, urine was performed according to generally accepted methods of zoochemical analysis. For feeding young animals of experimental groups of rabbits used complete ration granular feed, in the structure of which there was a different content of feed additives. Rabbits were fed complete feed granular feed where the content of wheat bran was – 25.7%, barley grain – 13.0%, corn grain – 5.0%, soybean meal – 2.5%, sunflower meal – 15.0%, hay flour alfalfa – 25.0%, oats – 10.0%, table salt – 0.35%. The nutritional value of granular complete feed for all experimental groups of rabbits was the same. According to the balance experiment, the best indicators of nutrient digestibility were found in young rabbits of New Zealand breed, with a feeding dose of feed additive TC VMP in the composition of granular feed – 3.5%. At this dose, the coefficient of digestibility of organic matter was 63.3%, crude protein – 67.9, crude fat – 74.1, crude fiber – 24.8 and nitrogen-free extractives – 72.3%, which increased the digestibility of organic matter by 2.5%, crude protein by 3.9% (p≤0.05), crude fat by 2.9%, crude fiber and BER by 1.9 and 2.6%, respectively, in young rabbits, with intensive rearing on meat. It was found that in the body of animals of the experimental group, which were fed as part of the feed additive of TC VMP in the amount of 3.5%, the ratio between the amount of nitrogen absorbed from the consumed rabbits of this experimental group was dominated by animals from the control group by 2.92% 0.05). Thus, research data indicate a positive effect of feed additive TC VMP on the growth and development of young rabbits of New Zealand breed.

The article covers addition of chlorella suspension, its effect on nitrogen balance, digestibility of nutrients and amino acids, pig productivity. Various feed additives, micro-element mixtures, and vitamins are used in animal nutrition to deal with the deficiency ofcertain vitamins and mineral elements in the rations. The peculiarity of chlorella suspension as a feed additive is in the ability to cultivate it throughout the whole year and in the availability of optimized technologies for its cultivation and use. Chlorella suspension is rich in proteins, minerals, vitamins, fatty acids and fiber. Introduction of chlorella suspension into pigs’ diets has helped to increase the digestibility coefficients of both inessential (by 7.5 %) and essential (by 2 %) amino acids. Feeding the animals with chlorella suspension has also resulted in the release of nitrogen retained in animals’ bodies by 13 % compared to the control group. The additional use of chlorella suspension in the diet of fattening pigs (large white) was found to increase the average daily gain by 21.9% compared to the control group which did not receive chlorella suspension. The conversion of animal feed to obtain 1 kg of live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg, and the conversion rate of feed in the experimental group was higher by 21.4 %.Feeding young pigs with chlorella suspension increases the digestibility of protein by 4.5 %, fiber by 2.0 %, fat - 0.7 %, essential amino acids - 81.6 %. The introduction of chlorella suspension to pig rations leads to an increase in the level of nitrogen in their body by 54.7 %of that taken with feed and 69.15 % of that digested in the body. Pork production profitably using chlorella suspension stood at 12.3 % , which is more by 87,8 % compared to the control group.
