Introduction. Currently, various biologically active substances, preferably of biological and not synthetic origin, with having a growth stimulating effect, are frequently used as food additives in the poultry industry. Some of these substances with a stimulating effect on the growth of chickens are represented by the biomass obtained from apathogenic strains of Streptomycetes. Material and methods. The investigations were conduvted within the ILR “Avicola Sărătenii-Vech” v. Sărătenii Vechi, Telenești district. The biological material was one-day-old Adler's silver chickens. The research was carried out on 150 chickens (one control and two experimental), which were randomly distributed in three groups of 50 chickens in each. Results. The dynamics of body weight was higher in the experimental group of chickens which, received biomass of Streptomycetes, indicating that the chickens in experimental group II recorded a 5.1% increase in body weight compared to chickens from the control group. The analysis of blood indices showed a slight increase of the number of lymphocytes and eosinophils, from 4 to 9% in experimental group II.  Conclusions. The use of biomass of Streptomycetes in feeding the experimental grup of chickens demonstrated an increase of body weight with 5.1% compared to the chickens from the control group. The biomass of Streptomycetes stimulated an increase of the number of limbocytes and eosinophils in chickens from the experimental group II, thus demonstrating an immunostimulatory effect.

The work considers the causes of the coronary X syndrome development in women by assessing the experimental group and the control group with typical angina pectoris with angiographically altered vessels. Each group included 30 patients. When studingy medical records of the patients in the study group, we found out that in the reproductive period all of them had hyperestrogenemia, confirmed by the laboratory data, with the corresponding consequences in the form of various gynecological diseases, while the patients of the control group had unburdened gynaecological history. In terms of the lipid spectrum, the results turned out to be opposite. In the experimental group, the rates were within the normal range, and the control level of LDL-C significantly exceeded the required values. Despite the fact that estrogens increase the concentration of high density lipoprotein (HDL) in the blood and lower the content of low density lipoprotein (LDL) that are atherogenic, their surplus has a less negative effect than their lack, as the risk of developing atherosclerosis increases with decreasing concentration, and with an increase there is a risk of developing endothelial dysfunction, which provokes the development of coronary syndrome X. These date confirm the development of endothelial dysfunction in the patients of the experimental group with hyperestrogenemia in the history resulted from the impairment of the process of proliferation of endothelial cells with subsequent imbalance of secretion of biologically active substances. Among them, there is nitric oxide, which causes the relaxation of smooth myocytes, thus resulting in vasodilatation, and endothelins, providing the opposite, vasodilating effect. Prostacyclines and thrombomodulins secreted by the vascular endothelium in physiological conditions, counteract platelet aggregation. In the case of damage to the vascular wall, the production of prostacyclin and thrombomodulin is suppressed, but the release of thromboplastin, platelet activation factor and von Willerband factor activates that promote platelet aggregation and blood clotting. Under the participation of other physiologically active substances, selectins, endothelial cells promote adhesion to their surface and further penetration into the site of inflammation of neutrophils, blood acidophils. Selectin is accumulated in the cytoplasm of the endothelial cells in the form of specific electron-cellular inclusions, the so-called bodies of Weibel-Palade. Normally, vascular endothelium is impervious to blood components. However, being affected by a number of factors, and in particular histamine, endothelial cells lose contact with each other and decrease in number. This leads to the release of water and plasma proteins into the intercellular medium causing oedema. Due to the ability of the inner layer of vessels to produce a large number of biologically active substances, such changes can hardly be corrected by therapy.

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 research data on the impact of deficient dietary microelements (cobalt and selenium) and biologically active supplement Humilid  on the indicators of the reproductive function of heifers after the first calving. We have found out that Humilid and trace elements influence on the physiological state of reproductive organs and stimulate the sexual heat of animals. Regarding the duration of the period from calving to fertilized insemination, the difference between the control and experimental groups is more visible. Thus, the service period in the experimental group I (under the influence of Humilid) was 293.2 days, which is 2.6 days less than in the control group. In the experimental group II (under the influence of cobalt and selenium), it was, respectively, by 3.9 days less than in the control one. This may indicate that the minerals and dietary supplements contribute to more rapid recovery of the ovarian cycle. Protein composition of blood serum was investigated in the study of the biochemical spectrum of blood. Balancing the nutrition of animals with deficient dietary microelements and adding Humilid increase the concentration of protein molecules, which is visible from the indicator of crude protein and its components - albumen and globulin.In comparison with animals in the control group, a total protein level of heifers in the experimental group I was higher by 8.8% (P <0.05), and in the experimental group II - by 8.6% (P <0.05). This may indicate the increased intensity of synthetic and redox processes in heifers’ bodies in preovulatory period which serve best for the insemination.The level of albumen was also higher by 8.0 and 7.3% respectively under the influence of Humilid and trace elements in relation to the control group, indicating the improvement of transport of substances, in our case estradiol.As far as globulin is concerned, the growth of this class of proteins was marked by 9.4 and 9.6%, indicating the improvement of the level of resistance of the organism. Thus, the increase in blood biochemical parameters creates certain conditions in heifers’ body to improve their insemination.

This paper presents the results of experimental studies the influence of biologically active substances of propolis on micromorphometric parameters of the ileum in young pigs. The results of the experiment make it possible to ascertain a change in the functional activity of the studied organ after the use of the drug from propolis. Since the most active process of absorption of monomeric hydrolysis products, especially amino acids and carboxylic acids, occurs in the ileum. Hydrolysis of intermediate products to monomers and preparation of the transition to absorption is carried out by enzymes fixed on the intestinal cell membranes. And the level of bioconversion of feed and retention of nutrients depends on their shape and structure, which ultimately affects the payment for feed with products. Therefore, the study of the histology of the small intestine and especially the ileum is of great importance. So, as a result of the study, it was found that the most characteristic histological changes in the structural components of the intestinal wall are observed in young animals of the experimental groups. The thickness of the main lamina of the mucous membrane of the ileum in piglets in the control group is 308.28 ± 2.81 µm, in piglets in the experimental group – 255.49 ± 0.75 µm. The height of the villi of the ileum, in the animals of the control group, is significantly lower and amounts to 193.89 ± 2.66 µm versus 280.97 ± 3.37 µm in the experimental group. Similar changes are observed in young animals of the older age group. The height of intestinal villi in pigs of the experimental group significantly exceeds the indicator of the control group and is 256.89 ± 1.62 µm and 163.96 ± 0.61 µm, respectively. The muscle plate of the intestinal mucosa of the pigs in the experimental group is significantly thicker than the control and is 17.8 ± 0.2 μm and 8.89 ± 0.08 μm, respectively. The obtained experimental material substantially supplements the information on the biological properties of propolis preparations. In practical veterinary medicine, research results can be taken into account when prescribing propolis for medicinal and prophylactic purposes. Since histological analysis of intestinal sections did not reveal destructive or pathological changes in any of the compared groups. In feeding, using the obtained practical material, we can specify the stimulating effect of the propolis preparation to intensify the growth of animals depending on the age of the pigs.

Numerous studies have shown that sapropel is an effective source of macro-and microelements, as well as biologically active substances. There are about 3 million lakes on the territory of Russia, where sapropel reserves are estimated at 250 billion tons. There are 497 lakes on the territory of the Tyumen region, the estimated reserves of sapropel in them are 1398,7 million tons. The Tyumen region is a biogeochemical province for all normalized trace elements. Biologically active compounds obtained from natural raw materials, including normalized trace elements in organic form are the most promising and safe. Under the inviroments of the Tyumen region, such natural raw materials can be sapropels. The study of the effectiveness of the use of sapropels and their influence on the metabolism and milk productivity of cattle is an urgent topic. The purpose of the research was to study the influence of sapropel lake Nepryak on milk productivity indicators and the biochemical composition of the blood of cows. For the experiment 3 groups of cows have been formed (a control group and two experimental ones) based on the principle of pairs of analogs. Cows of the 1st experimental group have been got in the ration of 300 g of sapropel per head/day, 2nd experimental – 500 g/head/day. Cows of the control group did not receive sapropel in the ration. It has been found as the result of research that the use of sapropel lake Nepryak in feeding of cows in doses of 300 and 500 g/head/day had the positive influence on their milk productivity. At the same time, it is most effective to feed sapropel at the dose of 300 g/ head/day.

Abstract The present in vitro study investigated the influence of doxazosin on the contractility of the urinary bladder in female pigs with experimentally induced cystitis. Fifteen juvenile female piglets (18-20 kg body weight) were randomly assigned into three groups (n=5 animals each): i) control (clinically healthy animals, without doxazosin treatment), ii) animals with induced inflammation of the urinary bladder, but without doxazosin treatment (experimental group I) and iii) animals with inflamed bladder, treated orally with doxazosin (0.1 mg/kg body weight for 30 days; experimental group II). Thereafter, the pigs were sacrificed and strips of the bladder trigone were suspended in organ baths. The tension and amplitude of the smooth muscles was measured before and after exposition to 5-hydroxytryptamine (5-HT; 10-6-10-4 M), acetylocholine (ACh; 10-5-10-3 M) and norepinephrine (NE; 10-9-10-7 M). 5-HT caused an increase in the tension of contractions in all the groups and the amplitude in the experimental groups, however, the effect was higher in the experimental group I than in group II as compared to that found in the pre-treatment period. ACh caused an increase in the tension in the control group and a decrease in the amplitude in both experimental groups; these changes significantly differed between the control and doxazosin-treated group. NE caused a decrease in the tension in both experimental groups and amplitude in all the groups, however, the effect was most strongly expressed in doxazosine-treated group. The present study has revealed that long-term administration of doxazosin causes a desensitization of the detrusor smooth muscle to in vitro applied mediators in the autonomic nervous system.

This paper examines the development of a fundamentally new automated hydroponic system for growing green fodder, which creates a solid fodder base capable to satisfy the need of livestock for nutrients throughout the year with low material costs. The new hydroponic green fodder produced according to the developed technology contained the required nutrients that contribute to the digestion of proteins, fats and carbohydrates into easily digestible organic components (amino acids, fatty acids and simple sugars) which are simpler in their structure. Moreover, it completely replaced compound feed, a mineral supplement in the diet of milking cows, and reduced the amount of fodder needed. In dry matter, compared to fodder barley, the content of protein (128.93%) and fat (196.73%) were higher, and biologically active substances were also formed. The new fodder used the nutrients of the diet more efficiently, increased milk production and reduced fodder costs. When hydroponic green fodder from barley was introduced into the diet of cows with 100% replacement of the compound fodder and 50% replacement of grain mass, milk yield in the experimental group exceeded the yield in the control group by 6%. An additional 549.5 kg was obtained from each cow for lactation, and 549.5 × 20 = 10990 kg was obtained from the entire experimental group. The annual income from feeding green fodder was 329710 rubles at the purchase price of milk of 30 rubles / kg (10990 × 30), and the daily efficiency of compound fodder was (80.6 × 20) = 1612 rubles; for the period of lactation it was 491660 rubles. Keywords: technology, new fodder, productivity, milk quality, resistance
