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%.

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

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.

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.

Aim. Study of the effect of new domestic lactulose-containing feed additives on the biological properties and amino acid composition of the protein in broiler chicken meat. Material and Methods. During the research, classical and modern methods were used: zootechnical, biochemical, etc. The methodological basis was the scientific works of domestic and foreign scientists who studied the features of the effect of feed additives on the body of poultry and its productive qualities. The mass fraction of protein was determined by the Kjeldahl method according to GOST 25011-2015, the mass fraction of fat – by the Extractive-weight method according to GOST 23042-2015, the mass fraction of moisture – by the thermogravimetric method using the ELVIZ moisture analyzer, the mass fraction of total ash – GOST 31727-2012 (ISO 936:1998), amino acid composition of pectoral muscles – by capillary electrophoresis (Kapel 105M). Results. As a result of the experiment, it was found that the use of additives No. 1 and No. 2 helps to stabilize the indices of digestibility of nutrients and, as a result, to improve the metabolic process in the body of the bird. It was found that the digestibility coefficient of dry matter in the experimental groups was by 0.91%, crude protein – by 1.68%, crude fat – by 0.79%, nitrogen-free extractable substances – by 1.33% higher than in the control group. Positive dynamics was also noted in the increase in the weight of the gutted carcass in the experimental groups by 5.47 and 4.46% in comparison with the same indicator in the control group. The use of lactulose-containing additives when growing broilers has led to an improvement in the quantitative and qualitative characteristics of the resulting product ("white" meat). An increase is observed in the value of the mass fraction of protein by 0.5 and 0.6%, respectively, in comparison with the mass fraction of protein in the meat of the control group. The studied feed additives balanced the ratio of essential amino acids to replaceable ones. During the experiment, it was found that in the white meat of the experimental groups, in comparison with the white meat of the control group of broiler chickens, there was an increase in the content of essential amino acids on average by 0.31 г/100 г (3.6%) и 0.41 г/100 г (4.7%), respectively. Conclusion. In terms of a set of indicators, the meat of broiler chickens grown with the use of new lactulose-containing additives No. 1 and No. 2 has higher indicators of meat quality compared to the control. New domestic prebiotic supplements based on lactulose No. 1 and No. 2, used in the experiment, are not only a natural alternative to antibiotics, hormones or other growth stimulants, but also a mechanism for a better approach to the formation of general beneficial physical and biochemical properties of meat of broiler chickens. Given this, these additives can be recommended for widespread implementation in poultry farming.

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of 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.

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. Key words: digestibility coefficient, young rabbits, compound feed, organic matter, protein, fat, fiber, copper.
