В условиях научно-производственного опыта исследована эффективность введения кормовой добавки «Абиотоник» в рацион высокопродуктивных голштинизированных симментальских коров (в транзитный период и на раздое). «Абиотоник» представляет собой усовершенствованный аналог известного импортного препарата «Чиктоник», отличаясь от иностранного аналога многократно увеличенной концентрацией пептона и наличием высокодефицитных микроэлементов (селена и элементоорганического соединения йода). Наши исследования показали, что скармливание препарата «Абиотоник» в дозе 150 мл/гол. способствовало росту продуктивности коров на 5,84%, улучшило физико-химические свойства молока и повысило его пищевую ценность. Применение кормовой добавки способствовало также профилактике желудочно-кишечных заболеваний у коров, повышению их резистентности, о чём свидетельствовали показатели крови и бактериологического исследования кала. Заболеваемость коров в опытной группе не наблюдалась. Использование препарата «Абиотоник» коровам в заключительной стадии сухостойного периода и в начале лактации привело к сокращению времени отделения плаценты у коров после отёла на 6,54%, или на 0,4 часа, повышению живой массы новорождённого молодняка на 1,6% и сокращению сервис-периода у опытных коров на 8 дней по сравнению с контрольными. Использование кормовой добавки «Абиотоник» способствовало получению дополнительного дохода от реализации молока в размере 1152 руб./гол. Полученные экспериментальные данные позволяют рекомендовать использование отечественной импортозамещающей кормовой добавки «Абиотоник» в рационах коров транзитного периода и на раздое в дозе 150 мл/гол. ежедневно в последней фазе сухостоя и через день в течение 40 суток после отёла. Under the conditions of scientific and farm scale trial the efficiency of introduction of the feed additive "Abiotonic" into the diet of highly productive Holsteinized Simmental cows (during the transition period and for days in milk) was studied. "Abiotonic" is an improved analogue of the known imported preparation "Chiktonik" differing from the foreign analogue by its manifoldly increased peptone concentration and the presence of highly deficient microelements (selenium and organo-element compounds of iodine). Our researches have shown that feeding the preparation "Abiotonic" at a dose of 150 ml / head contributed to an increase in cow productivity by 5.84%, improved the physicochemical properties of milk and increased its nutritional value. The use of a feed additive also contributed to the prevention of gastrointestinal diseases in cows, an increase in their resistance as evidenced by haematological parameters and bacteriological feces analysis. The incidence of cows in the experimental group was not observed. The use of the preparation "Abiotonic" for cows in the final stage of the dry period and at the beginning of lactation reduced the time for separation of the placenta in cows after calving by 6.54% or 0.4 hours, increased the live weight of newborn young stock by 1.6% and reduced the service period of experienced cows by 8 days compared with the control ones. The use of the "Abiotonic" feed additive contributed to the receipt of additional income from the sale of milk in the amount of 1152 rubles / head. The obtained experimental data allow us to recommend the use of domestic import-substituting feed additive "Abiotonic" in the diets of cows in the transition period and for days in milk at a dose of 150 ml / head daily in the last phase of dry period and every other day for 40 days after calving.

Исследования проводились в Алтайском крае на коровах Приобского типа черно-пестрой породы. Было сформировано 4 группы коров 3 лактации, аналогов по живой массе (500 кг), в период сухостоя, по 10 голов в каждой. Молочная продуктивность по последней контрольной дойке перед запуском составляла в среднем 22,5 л. Тканевый биостимулятор вводили с интервалом 14 дней, четырехкратно в период сухостоя и четырехкратно в период раздоя. В I опытной группе доза тканевого биостимулятора составляла 15 мл/гол., во II — 22,5 мл/гол., в III — 30 мл/гол. Опытную партию тканевого биостимулятора изготовили из субпродуктов и боенских отходов пантовых оленей. Наиболее оптимальной дозой применения тканевого биостимулятора следует считать 22,5 мл/гол, она способствовала сокращению времени прихода коров в первую половую охоту после отела на 3,9%, повышению результативности осеменения до 30,0%, уменьшению сервис-периода на 17,5% (P≤0,05) и индекса осеменения на 32,0%. The studies were conducted in in the herd of Black-Pied cows of the Priobskiy type. Four groups of 10 dry cows at the age of the 3rd lactation and comparable in live weight (500 kg) were formed. The milk yield at to the last control milking before drying-off averaged 22.5 liters. The tissue bio-stimulant was administered two weeks apart, four times during the dry period and four times during the first 100 days of lactation. The tissue bio-stimulant was administered in the following doses: in the 1st trial group — 15 mL per head; 2nd trial group — 22.5 mL per head; 3rd trial group - 30 mL per head. The trial batch of the tissue bio-stimulant was made from velvet antler deer by-products and slaughterhouse offal. The tissue bio-stimulant dose of 22.5 mL per head should be considered the most optimal one; it shortened time of coming in the first heat after calving by 3.9%, increased insemination effectiveness to 30.0%, shortened the service period by 17.5% (P≤0.05) and decreased the insemination index by 32.0%.

Изучено влияние на репродуктивную функцию коров белково-витаминно-минеральных концентратов (БВМК) с кормовой добавкой «AMG-COMPLEX», состоящей из эфирных масел и растительных экстрактов. Для проведения опыта были сформированы контрольная и опытная группы по 70 голов с учетом количества дней до отела из коров второй и третьей стельности. Животным контрольной группы скармливали основной рацион. Для коров опытной группы были составлены рационы с БВМК, которыми заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Они получали БВМК для сухостойных коров в количестве 300 г на 1 голову в сутки с 60-го по 20-й день до отела и по 200 г на 1 голову в сутки с 20-го дня до отела. После отела 60 дней им скармливали БВМК для раздоя в количестве 1200 г на 1 голову в сутки. Использование БВМК в рационах коров опытной группы способствовало улучшению у них репродуктивной функции и снижению частоты гинекологических заболеваний после отела в 4,5 раза. Индекс осеменения в опытной группе составил 1,73 (P≤0,05), что на 0,76 ниже, чем у животных контрольной группы. Средняя продолжительность сервис-периода в опытной группе составила 87,71 дня (P≤0,01) и была короче, чем в контроле, на 14,72 дня. The effect on the reproductive function of cows of the protein-vitamin-mineral concentrate with the feed additive ʺAMG-COMPLEXʺ, consisting of essential oils and plant extracts, was studied. To experiment, taking into account the number of days before calving, control and experimental group of 70 heads each were formed from cows of the second and third pregnancy. In the scientific and economic experiment, the cows of the control group consumed the feed of the main rations. For the cows of the experimental group rations were made with PVMC, which replaced the proportional amount of concentrated feed and a part of the vitamin-mineral premix. They received PVMC deadwood in the amount of 300 g per 1 head per day from 60th to 20th day before calving and 200 g per 1 head per day 20 days before calving. 60 days after calving they received PVMC lactation in the amount of 1200 g per head per day. Feeding PVMC to cows of the experimental group contributed to the improvement of reproductive function and a decrease in the frequency of gynaecological diseases after calving by 4.5 times. The insemination index in the experimental group was 1.73 (P≤0.05), which is 0.76 lower than in the animals in the control group. The average duration of the service period in the experimental group was 87.71 days (P≤0.01) and was shorter than in the control by 14.72 days.

The use of nanomaterials in poultry farming has become increasingly popular as feed additives capable of increasing the productivity of the herd. Nanocrystalline cerium dioxide belongs to nanomaterials with a broad spectrum of activity. Owing to their oxygen non-stoichiometry and low toxicity, cerium dioxide nanoparticles are a very promising object for agriculture. The paper presents the results of studying the meat productivity of quails of the Pharaoh breed when drinking nanocrystalline cerium dioxide in the composition of the feed additive “Nanocerium”. The study was carried out on quails during the rearing period from 14 to 49 days. For the experiment, two groups (control and experimental) of 24 heads each were formed from one day old poultry. The quails were kept in a vivarium, in cage batteries, subject to the accepted microclimate conditions. Poultry of both groups received compound feed, developed taking into account age and physiological characteristics. With drinking water, the of the experimental group additionally received nanocrystalline cerium dioxide as part of the feed additive “Nanocerium” at a dose of 8,6 mg per liter of water for 35 days. The quail population was counted and weighed weekly, starting from the day-old age. The following indicators were determined: safety, dynamics of live weight, average daily gain in live weight. According to the results of the control slaughter and anatomical cutting, the weight of the carcass and the weight of the edible part were determined. Slaughter qualities and morphological composition of quail carcasses were determined by anatomical cutting with the measurement of the following parameters: pre-slaughter weight, half-battered carcass weight, carcass patrana, slaughter yield, weight of edible parts. Drinking the feed additive “Nanocerium” by young quails increased their safety by 4.17%, live weight and absolute average daily gain by 20.3 g and 0.48 g (P <0.05), respectively. The addition of NDC quails to drinking water contributed to an increase in their pre-slaughter weight by 19.3 g, half-gutted carcass by 18.0 g, and gutted by 17.5 g in comparison with the control group. The quail carcasses of the experimental group had a higher yield of edible parts in comparison with the poultry that consumed pure water. Key words: quail, nanocrystalline cerium dioxide, safety, body mass, gain, slaughter rates, output of edible part.

One of the most important factors for increasing efficiency is the organization of complete ration feeding is to provide farm animals with all the necessary micro- and macroelements. In this regard, rations should be developed on the basis of detailed norms, taking into account the actual chemical composition and nutritional value of the feed used. The purpose of the research was to study the influence of the feed additive Biovitel on the morphological and biochemical parameters of the blood of steers of Hereford breed under intensive fattening technology. On the base of laboratory blood tests it was possible to trace the effect of the feed protein additive Biovitel on the morphological and biochemical parameters of the blood of experimental animals. The correlation of hematological parameters and productivity of animals when using the feed protein additive Biovitel has been evaluated. It has been found that the use of the protein feed additive Biovitel for steers during the fattening period is an effective means to reduce production losses and has a positive effect on the morphological and biochemical parameters of animal blood. The obtained data indicate that the blood parameters were higher in the animals of the experimental group throughout the entire period of research, which contributes to the increase in the physiological status of the animal organism. The revealed correlation coefficients of the live weight of steers with the biochemical parameters of the blood of animals have shown the presence of closer correlation coefficients in the experimental group of steers have been received the feed additive Biovitel.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

One of the real ways of increasing the production of livestock products is to increase the conservation of young animals, the mortality rate of which remains at this time still very high. Many calf treatment regimens have been developed, but they are not always effective, which prompts scientists and practitioners to improve already known methods of treatment, to find and justify new medical preparation. Material for research were dry-cows, healthy and sick calves. After the clinical examination of cows, the experiment was conducted in two phases: the first phase – in 3 groups of cows, the second – in clinical healthy and sick calves. Mineral supplement of Sapocorm were added to the first experimental group of cows; cows of the second experimental group – the preparation Betamint; animals of control group get basic diet. At the second phase, a group of healthy calves, as well as control and two experimental groups of patients were formed. The first group was treated with Intecol in combination with the probiotic Vetom. Calves of the second group – the preparation Intecoll, but in a complex with electrolyte solution Electrosol oral. The calves of the control group were treated with 4% solution of gentamicin sulfate and 30% solution of natrium thiosulfate. It was found out that during the dry period, cows were often subjected to metabolic disorders, and the causes of digestive disorders in calves were associated with a metabolic disorders in cows as a result of malnutrition. In the first stage of the research, the data obtained show the stimulatory effect of Betamint on the processes of hemopoiesis of the cows. In other side,  the probable magnification increase hemoglobin in the blood of cows can be explained by the influence of the components of the preparation on the metabolism of proteins. In cows of the first experimental group, which received the mineral supplement of Sapocorm, there were no probable changes in these indices. The next stage of the work was aimed at studying the effectiveness of preparation for the treatment of sick calves. In the analysis of biochemical parameters, was obtained low effectiveness of control group treatment, which was manifested by a slight increase in the biochemical parameters of the blood of diseased calves, which indicates an ineffective action of preparation. In the treatment of calves in the first group, the general condition was normal within 4–5 days of treatment. This indicates the complex effect of compounds and other elements that are components of the preparation Intecol and probiotic Vetom, on restoring the structure and functions of digestion. An analysis of the biochemical parameters of the blood of the second group when treated with the preparation Intecol and Electrosol oral plagued the normalization of the general state occurred within 2–3 days of treatment. The revealed changes indicate the complex influence of nutrients, which are components of the preparation Electrosol oral. On the basis of the conducted studies, the positive influence of the proposed treatment regimens and the effectiveness of the use of a complex of preparation with the antibiotic “Intecol” has been proved.

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.
