The results of studies on feeding biologically active additives suspensions of chlorella and Bactistatin in the diets of primates are presented. Its positive effect on the bioconversion of diets was experimentally established. The coefficients of digestibility of nutrients with dry chlorella and fishmeal in the composition of complete feed were determined. The obtained experimental data are important for the preparation of scientifically grounded and optimally balanced feeding rations, taking into account the digestibility of feed. This will optimally balance feed rations for all nutrients, while reducing feed costs and, as a result, increasing the profitability of keeping primates. It was found that the introduction of chlorella powder and fishmeal into the diet improves protein absorption by 6.83 and 5.66%, crude fat - by 2.61 and 3.92, crude fiber - by 4.78 and 4.25, NFES - by 4.15 and 2.26, crude ash - by 18.93 and 12.08%. The use of calcium and phosphorus macronutrients was higher in the 3rd experimental group, which received 14% chlorella in the main diet by 1.38 and 8.07%, respectively. In the 5th experimental group, which received 18.26% of the main ration of fishmeal, calcium was absorbed more efficiently by 4.77, and phosphorus - by 1.21%. The use of diet supplements in the form of a suspension of chlorella and Bactistatin helped to stimulate the bioconversion of nutrients in the diets used in the nursery for feeding monkeys, and enabled to maintain the main blood parameters within physiological norms.

The article presents the results of the influence of new recipes for feed additives made on the basis of local resources on the biochemical parameters of the blood of dairy cows of the Simmental breed in the conditions of Yakutia. Research objectives: 1) study the chemical composition of new recipes for feed additives produced from local resources; 2) determination of the influence of the new formulation of feed additives from local resources on the biochemical parameters of blood in cattle of the Simmental breed. In our experiments, there were no statistically significant changes in the biochemical parameters of blood during the period of the experiments, all the studied blood parameters, both at the beginning and at the end of the experiments, in all groups of animals were within the physiological norms and did not have significant differences between the groups. Consequently, feeding the formulation of feed additives in the composition of Tammi barley, Tuymaada wheat, Pokrovsky and Vilensky oats, dry brewer's grain, Hongurin zeolite, Hongurinobakt probiotic in the diet of cows and heifers of the Simmental breed contributed to the activation of vital processes in the body, assimilation of feed and improved appetite. It should be noted that the cows of the II-experimental group showed a tendency to increase the composition of amino acids. At the beginning of the experiment, the blood lysine content increased by 5.22 mg /% compared with the control and by 5.79 mg /% with the I-experimental group, methionine by 19.67 mg /% and by 10.02 mg /% respectively. The same pattern is observed for the rest of the amino acid composition at the end of the experiment. The data obtained indicate that the optimization of the feed rations of Simmental cows in terms of the content of vitamins of groups A and C through the use of the formulation of protein-vitamin-mineral feed additives had a positive effect on the hematopoietic function. So, if the content of vitamins A and C at the beginning of the experiment was less, then at the end of the experiment the same indicators returned to normal.

The physiological state of animals is to a certain extent characterized by hematological indicators, since blood occupies a special place in the body. By transferring nutrients and biologically active substances, the blood performs the general regulation of vital functions of the body. The use of Vitartil as a feed additive in the diets of animals leads to an increase in glycolytic processes and a decrease in the body’s need for oxygen delivery, which contributes to the growth of the animal body. The purpose of the research was to study the changes in blood parameters taking into account the age of Hereford steers against the background of the use of Vitartil feed additive to the main diet and its effect on the productive traits of animals. In order to carry out the experiment two groups of steers-analogs of Hereford breed have been formed at the age of 6 months per 10 heads in each. The difference between the groups was that the steers of the experimental group have been received the feed additive Vitartil in addition to the main diet. The greater yield of the meat part was in the steers of the experimental group in comparison with the herdmates of the control group. This indicator in the experimental group was 78,9 %, while in the control group it was lower by 1,6 %. The animals of the experimental group were superior to their herdmates in terms of meat weight by 1,4 kg or by 8,8 %. The relative number of bones was lower in the experimental group and amounted to 18,4 %, and in the control group 19,2 %. The meat content index was high in the steer have been received the biologically active additive Vitartil and was 4,3, and in the control group 4,0. It has been found that the use of Vitartil feed additive to the main diet of Hereford steers increases the blood content of hemoglobin and glucose, which has a certain effect on the morphological and chemical composition of meat, as well as increases its energy value.

Жизненно важными микроэлементами для жвачных животных являются медь, цинк, марганец, железо, кобальт, йод, селен. Микроэлементы, в которых атом металла соединён и защищён белковыми молекулами, улучшают воспроизводительные качества самок за счёт повышения оплодотворяемости, уменьшения эмбриональной смертности, улучшения состояния мочеполовой системы или повышения интенсивности функционирования яичников. Поэтому в настоящее время актуальными являются разработка и внедрение в технологию кормления сельскохозяйственных животных наиболее эффективных препаратов с необходимыми биологически активными веществами. На основании проведённого исследования дано практическое обоснование использования в технологии кормления тёлок отечественной кормовой биодобавки на основе гидролизата соевого белка, витаминов и микроэлементов. Установлено её положительное действие на некоторые функции органов и систем животных. Экспериментально доказана эффективность её применения для оптимизации обменных процессов и повышения воспроизводительных функций тёлок. Так, биохимическим исследованием образцов крови подопытных животных установлено, что количество кальция и фосфора в крови у тёлок опытной группы по сравнению с контролем было достоверно выше на 2,35 и 2,9% соответственно. Эритропоэтическая фракция была более выражена у молодняка опытной группы. У тёлок опытной группы время от начала скармливания препарата до первой выраженной охоты и осеменения, по сравнению с контрольными животными, сократилось на 16%, а период от начала скармливания препарата до плодотворного осеменения – на 25,7%. Количество тёлок, пришедших в охоту и осеменённых в первый месяц, в опытной группе по сравнению с контрольной было на 43% больше. Оплодотворяемость тёлок опытной группы за учётный период составила 95%, что на 20% больше, чем у животных контрольной группы. Включение в рацион тёлок биодобавки в дозе 100 мл/гол. позволило получить дополнительно на 8,5% больше валового прироста живой массы по отношению к их аналогам. The vital trace nutrients for ruminants are copper, zinc, manganese, iron, cobalt, iodine, selenium. Microelements in which a metal atom is jointed and protected by protein molecules improve the reproductive qualities of females by increasing fertility, reducing embryonic mortality, improving the state of the genito-urinary system or increasing the intensity of ovarian functioning. Therefore the development and implementation of the most effective preparations with the necessary biologically active substances in the technology of feeding farm animals is currently relevant. On the ground of conducted research a practical substantiation of the use of domestic food supplement based on the hydrolyzate of soy protein, vitamins and trace nutrients in the feeding technology of heifers is given. Its positive effect on some functions of animal organs and systems has been established. The effectiveness of its application to optimize metabolic processes and increase the reproductive functions of heifers has been experimentally proven. Thus a biochemical blood samples analysis of experimental animals found that the amount of calcium and phosphorus in the blood of the heifers of the experimental group compared with the control was significantly higher by 2.35 and 2.9% respectively. The erythropoietic fraction was more defined in the young experimental group. In heifers of the experimental group the time from the beginning of feeding the drug to the first defined heat and insemination compared with control animals decreased by 16% and the period from the beginning of feeding the drug to prolific insemination – by 25.7%. The number of heifers that came to the heat and inseminated in the first month in the experimental group was 43% higher than the control group. The impregnation capacity of the heifers of the experimental group during the record period was 95% which is 20% more than in animals of the control group. Inclusion in the diet of heifers bioadditive at a dose of 100 ml / goal allowed obtaining additionally 8.5% more the gross body weight gain relative to their analogs.

When balancing ration it is necessary to remember that the active factors of feeding are not the feed itself, but the content of nutrients and biologically active substances in them. It has been developed and physiologically justified feeding rations of cows during increasing the milk yield period, which are based on succulent feed, hay, grain and rapeseed presscake and a source of minerals and vitamins PVMA have been used. The experimental part of the work has been carried out in the winterstall period in the educational and experimental farm in the State Agrarian University of the Northern Trans-Urals. It has been found that from cows of the experimental group during the increasing the milk yield period 1503 kg of milk containing 3,98 % fat and 2,87 % protein has been obtained. Animals of the experimental group exceeded cows of the control group in milk yield by 90 kg (P > 0,95), in terms of fat and protein content in milk their superiority was 0,37 abs.% (P > 0,999) and 0,21 abs.% (P> 0,999). Input into the rations of lactating cows rapeseed presscake in the amount of 2 kg/ head/day and PVMA in the amount of 100 g during 3 months of lactation gives an increase in productivity for the entire lactation in the experimental group by 572 kg of milk with additional products by 2745,2 Rubles can be obtained more. The positive effect of the input of rapeseed presscake in the rations of lactating cows in the amount of 2 kg/head has been established/day and PVMA in the amount of 100 g in the period of following on the subsequent productivity of animals.

The article presents the results of studies on the digestibility of nutrients and the metabolism of calcium and phosphorus in dairy cows. The balance of minerals in the body of cows when feeding feed additives from local resources indicates that the content of macro- and microelements in the diets of animals during the period of the experiments basically corresponded to the norms. The use of protein-vitamin-mineral supplements from local components (barley "Tammi", oats "Pokrovsky", dry brewer's grains, zeolite-hongurin, probiotic preparation "Khongurinobakt", as well as factory components: mineral premix "Megamix", synthetic amino acid – lysine and table salt) balanced the diet for missing nutrients and improved the palatability of the main feed. In the studied diets, 1 ECU had digestible protein – 107.1 g, 125 MJ of metabolic energy and 14.81 kg of dry matter. The ECE concentration in 1 kg of dry matter was 0.66. Feeding by cows of the 2nd experimental group of the recipe for feed additives No. 2 contributed to better digestibility and use of nutrients in the rations. The digestibility of nutrients of cows was higher in cows of the 2nd experimental group, while a high level of digestibility in comparison with the control and 1st experimental groups was established in relation to dry matter by 1.0 and 1.5%, organic matter by 2.8 and 2.0%, crude protein by 3.3 and 2.0%, crude fat by 2.3 and 1.5%, crude fiber by 3.0 and 2.0% and BEV by 0.5 and 1,3%. As a result of the study of the balance of minerals in the body of cows, the positive effect of using feed additives from local resources in the diets of cows has been proven. Consequently, the improvement in the metabolism of calcium and phosphorus in the diet is explained by the fact that protein-vitamin-mineral feed additives had a stimulating effect on the state of metabolic processes and the health of animals in general.

Aim of the research was to study the effect of premix with buffering properties in diets for newborn cows on their milk production, blood biochemical composition, microbiological parameters of scar fluid and its acidity. The experiment was carried out on 2 groups of calving black-motley cows, selected on the basis of the pair-analogue principle with 6 animals each. The first, control group of cows received a ration adopted on the farm. The second group of animals received the same diet, only instead of 0.5 kg of compound feed they used a multicomponent mineral premix enriched with biologically active additives, which has buffering properties, which is very important in the newborn period of cows. Feeding premix with buffering properties in the composition of the main diet to newborn cows contributed to an increase in the consumption of dry matter by animals. Since the cows of the second experimental group consumed more nutrients, a significant increase in the average daily milk yield was found. The studied premix helped establish a tendency to improve metabolic processes in the body of ruminants. In a scientific experiment, a positive effect of the buffer premix on the microbiological parameters of scar fluid, as well as its acidity and acid-binding ability, was established. The consumption of more nutrients was due to a significant increase in average daily milk yields by 9.1%. The results of biochemical studies of blood serum allow us to say that all indicators characterizing the metabolism were within the physiological norm in cows of both groups. Also, a qualitative change for the better in the microbiological parameters of scar fluid was noted. Feeding the studied premix to experienced animals contributed to the additional profit of 4069.8 rubles per head.

The pre-incubation treatment of eggs of the Ross 308 cross-country with a composition consisting of colamine, succinic acid, serine and vitamin B6 had a positive effect on the incubation biocontrol parameters, antioxidant status and histogenesis of some internal organs of the poultry gastrointestinal tract. Thus, the output of chickens in the experimental batch exceeded the control by 2.47%, and the hatchability by 2.23%. The thermogenesis of chickens from the experimental group was also better; the temperature was significantly higher by 0.7-1.3 ° C (p <0.05, p <0.01) as compared with the control. The antioxidant properties of this composition contributed to a decrease in the ORH level by 2.5 times (p <0.05), (MDA) - by 1.3 times (p <0.05), with an increase in the peroxidase activity by 17.65%, SOD- 1.6 times (p <0.01), respectively, relative to the control. internal organs for histological examination were taken. The decrease in the anomalous intensity of free-radical reactions and, as a result of lipoperoxidation, had a positive effect on the histoarchitecture of the muscular and glandular stomachs. Thus, a tendency to an increase in the thickness of the mucous membrane of the muscular stomach by 16.6% was recorded, as well as its cuticle significantly 1.4 times (p <0.05), glandular - 1.2 times (p <0.01) relative to control. These data allow us to conclude that the study of the histological characteristics of the stomachs in chickens at the age of day is an important marker of their future adaptive capacity in postembryogenesis. The literature suggests that increasing the thickness of the glandular mucosa will contribute to better digestion of feed, the viability of intramural regulatory processes, intestinal microbiocenosis and other functions of the digestive system as a whole.

It should be noted that the cows of the II experimental group showed a tendency to increase the composition of amino acids. At the beginning of the experiment, the blood lysine content increased by 5.22 mg/% compared with the control and by 5.79 mg /% — with the I experimental group, methionine — by 19.67 mg/% and by 10.02 mg/% respectively. The same pattern is observed for the rest of the amino acid composition at the end of the experiment. The data obtained indicate that the optimization of the feed rations of Simmental cows in terms of the content of vitamins of groups A and C through the use of the formulation of protein-vitamin-mineral feed additives had a positive effect on the hematopoietic function. So, if the content of vitamins A and C at the beginning of the experiment was low, then at the end of the experiment the same indicators returned to normal.
