Abstract The paper presents the results of a study to determine the effectiveness of complex feed additives in the fattening of culled cattle in the conditions of Yakutia. To conduct the experiment, 3 groups of culled cattle were formed. The use of complex feed additives from local natural raw materials in the feeding of culled cattle on fattening allowed increasing the live weight by 1.58% and 0.26%. To determine the safety of experimental feed additives, the clinical parameters of the body of experimental animals were studied. It was found that there was no significant difference between the groups and all the indicators were within the normal range, which in turn proves the harmlessness of complex feed additives. At the end of the experiment, a control slaughter of experimental animals was carried out. When analyzing the data of animal slaughter, it was found that the experimental groups were superior to the control group in terms of parameters: the mass of the steam carcass by 5.53% and 3.61%, the mass of visceral fat by 9.39% and 1.77%, the slaughter mass by 6.07% and 3.87%, the slaughter yield by 2.76% and 2.06%. Next, the organoleptic evaluation of meat products was performed. According to the results of the evaluation of boiled meat, it was found that the experimental groups exceed the control group by 12.92% and 8.33%, and exceed the roasted meat by 11.87% and 8.19%. Thus, complex feed additives showed effectiveness in fattening culled cattle in the conditions of Yakutia.

Abstract The paper presents the results of fattening young cattle in the conditions of Yakutia with the use of complex feed additives from local natural raw materials in their diets. One of the ways to increase the meat productivity of livestock is to optimize feeding by inserting complex feed additives into their diets. Therefore, studies were conducted to determine the effectiveness of complex feed additives in the fattening of young cattle in the conditions of Yakutia. At the beginning of the experiment, the live weight of the animals in the groups did not differ much, but starting from the age of 12 months, the superiority of the animals from the experimental groups is noted. In the period of 12-15 months of age, the animals from the experimental groups exceeded the growth rate of the control group by 6.70% and 4.76%. In the period of 15-18 months old, the animals of the control group were inferior to the experimental groups by 28.31% and 16.54%. On average, the animals of the experimental groups grew more intensively in comparison with the control group by 12.73% and 8.66 %. Analysis of animal slaughter data showed that the experimental groups were superior to the control group in a number of indicators, such as the mass of the steam carcass by 8.04% and 4.43 %, the mass of visceral fat by 18.59% and 7.39%. The organoleptic evaluation of meat products also confirmed the superiority of the experimental groups over the control group. Thus, the use of complex feed additives in the feeding of young cattle on fattening showed its effectiveness.

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.

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.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

In order to improve the digestibility and absorption of feed, metabolic processes, growth and development of animals, increase the resistance of the body immunomodulatory agents, probiotics, prebiotics, combined enzyme-probiotic feed additives are widely used. The purpose of our work was to conduct comparative clinical trials of the effectiveness of the probiotic feed additive Probion-forte in terms of productivity, blood indices and histological structure of individual internal  pigs organs during fattening. The researches were carried out on 120 piglets of big white breed at the age of 28 days, which were divided into 4 groups with 30 units in each one. The probiotics were added to feed in different concentrations in order to determine their efficiency and examine influence on piglets organism: the first group was given probiotic Probion-forte in dose of 1.0 g/kg (10 weeks); the second one – Probion in dose of 1.0 g/kg (6 weeks) and 0.5 g/kg (4 weeks); the third one was given probiotic Bio Plus 2B in dose of 0.4 g/kg for 10 weeks; and the fourth one was a control group. The compound feed was provided according to norms recommended for big white breed taking into account age. On the 42nd day (6 weeks) and on the 70th day of test 10 units were selected for haematological, pathomorphological and microbiological tests. The productivity of animals of all studied groups was evaluated by the average daily gains, safety, feed conversion and slaughter output. The stabilized with EDTA piglets’ blood was used for morphological studies, and blood serum – for biochemical studies. The clinical trials have shown that the application of Probion-forte, as a feed additive for fattening of piglets within 10 weeks after weaning, did not cause adverse reactions, was well tolerated by animals and contributed to the improvement of the processes of erythropoiesis and leucopoiesis, increased of serum total protein content. The increasing activity of serum transaminases indicated more intense metabolic processes in experimental animals’ organism, which was confirmed by increase in average daily weight gains and slaughter output compared to control. In the microscopic examination of the thymus, spleen, lymph nodes, intestines, liver, the characteristic histological structure of the organs was preserved and indicated their active morphofunctional state throughout the study period. Morphometrically the increase in the height of the villi in the duodenum and the size of the thymus lobes in piglets, which were fed with probiotic feed additives was established. The efficiency and appropriateness of the application of these products was confirmed in the first and second experimental groups. However, the most significant difference was observed in piglets fed with Probion-forte for 10 weeks at a dose of 1.0 g/kg of feed.

Эффективность применения кормовых пребиотических добавок в рационах телят возрастает в ранний (молочный) период их выращивания, когда происходит изменение трофических процессов, способов переработки пластических веществ, синхронизация биологических ритмов роста, развитие органов и систем организма, повышение чувствительности клеток к стимулирующим и тормозящим воздействиям. Цель работы заключалась в испытании кормовой пребиотической добавки, разработанной для профилактики и лечения диареи телят в молочный период выращивания. Опытная группа телят в период с 3- до 60-суточного возраста получала пребиотическую добавку в виде болюсов следующего состава (г): чистотел большой – 3,5; ромашка лекарственная – 3,5; куркума длинная – 0,6; аскорбиновая кислота – 1,2; фруктоза – 1,2; энтеросорбент – 2,0; сахар – 3,0; зерновая мука – 1,0. Суточная доза добавки, в зависимости от возраста и живой массы, составляла 12–16 г. В качестве энтеросорбента использовался глауконит Бондарского месторождения. В научно-производственном опыте установлено, что уже через два месяца экспериментального кормления отмечено статистически значимое различие в живой массе между группами, которое составило 2,1 кг в пользу опытных животных. Макроскопический анализ кала животных обеих групп показал, что консистенция, цвет и запах практически были одинаковыми, pH – слабокислая (5,23–5,22), примеси (кишечные паразиты и др.) отсутствовали, из чего следует, что секреторная и всасывающая функция желудочно-кишечного тракта у телят были нормальными. В контрольной группе у двух телят в течение первой недели после рождения были зафиксированы признаки нарушения функции желудочно-кишечного тракта (ЖКТ), которое сопровождалось диареей. Продолжительность болезни каждого телёнка составляла в среднем 4 суток. В целом, скармливание фитопребиотика в течение первых месяцев жизни телят оказало лечебное действие на простую диарею, обеспечило нормальное функционирование микробиоты кишечника, стимулировало увеличение среднесуточных приростов живой массы на 5%. The effectiveness of the use of prebiotic food supplements in diets of calves increases in the early (dairy) period of their growing when there is a change in trophic processes, methods of processing plastic substances, synchronization of biological growth rhythms, the development of organs and systems of the body, increasing the sensitivity of cells to stimulating and inhibitory effects. The purpose of the work was to test a food prebiotic supplement developed for the prevention and treatment of calf diarrhea during the dairy period of growing. Test group of calves from 3 to 60 days old received a prebiotic supplement in the form of boluses of the following composition (g): Chelidonium majus – 3.5; Matricaria chamomilla – 3.5; Curcuma longa – 0.6; ascorbic acid – 1.2; fructose – 1.2; enterosorbent – 2.0; sugar – 3.0; grain flour – 1.0. The daily dose of the supplement depending on age and live weight was 12–16 g. Glauconite of the Bondarsky deposit was used as an enterosorbent. In the research and production experiment it was found that after two months of experimental feeding a statistically significant difference in live weight between the groups was noted which amounted to 2.1 kg in favor of the experimental animals. Macroscopic analysis of feces in animals of both groups showed that the consistency, color and smell were almost the same, pH was slightly acidic (5.23–5.22), impurities (intestinal parasites, etc.) were absent which implies that the secretory and absorbing function the gastrointestinal tract in calves was normal. In the control group two calves during the first week after birth showed signs of a derangement of the function of the gastrointestinal tract (GIT) which was accompanied by diarrhea. The duration of disease of each calf averaged 4 days. In general feeding a phytoprebiotic during the first months of life of calves had a therapeutic effect on simple diarrhea, ensured the normal functioning of the intestinal microbiota and stimulated an increase in daily live weight gain by 5%.

Water treatment by contact non-equilibrium low-temperature plasma refers to innovative methods of processing food raw materials, which requires determining the level of safety of its use to meet the requirements of food safety for humans. The test animals were divided into four test groups with two different basic diets. The tested substances were drinking main water (control group) and plasma-chemically activated water (experimental group); wheat bread (control group) and wheat bread produced using plasma-chemically activated water (experimental group). It was found that there was no significant difference between the control and experimental groups of animals in body weight and its changes during 90 days of the introduction of the test substances into the diet. The amount of water and feed consumed was in direct proportion to the change in the weight of animals in the corresponding diets. The hematological and biochemical analysis of the blood of the test rats did not confirm the toxic or allergenic effect of the studied feeding factors on their organism. An increase in the number of erythrocytes in the blood and activation of the phagocytic activity of experimental groups of animals were confirmed. This confirms the positive effect of plasma-chemically activated water and wheat bread made with its use on metabolic processes in the body of animals. Macromorphological parameters of the body of animals and the results of histological studies of the stomach, liver, kidneys and femur as potential target organs demonstrated the absence of dystrophic-degenerative changes in these organs. A comprehensive study of the food safety of plasma-chemically activated water and wheat bread made with its use proves the possibility of using an innovative method of water treatment in food production.
