The spectrum of acaricides changes continuously and improves. At the same time, big attention is given to research of new, more effective preparations meeting modern requirements. Research on studying the efficiency of Akaribil preparation against swine sarcoptosis (Sarcoptidae) was realized in the conditions of swine breeding farm in the Republic of Belarus. The preparation possesses high insect-acaricidal activity. In the conditions of the preparation storage and repeated opening of a ware in the course of tests there were stated no changes in drug smell or color. The scheme of the preparation application is applied in industrial production technology. It possesses anti-inflammatory properties, antiseptic stimulating healing of skin damages, does not irritate integuments, renders weak irritating effect on mucous membranes of eyes. In recommended doses Akaribil does not cause any adverse effects and complicating disease. There were stated no contraindications to preparation application. High therapeutic efficiency against arachnoentomosis was proved. Application the preparation made it possible not only to reduce disease incidence and animal death, but also to facilitate the severity of scabietic diseases. As a result of realized research it was established that efficiency of Akaribil against swine sarcoptosis was 100%.

In the conditions of the Republic of Belarus there was realized a complex of studies of quality swine slaughter products against the background of combine applications of the albuminous-vitamin-mineral additive Immovit and an extract of hill-growing saltwort for the preventive maintenance and treatment of a toxic dystrophy of liver. Research results showed the analysed preparations did not render negative influence on quality and safety of produced meat products. Against the background of application of the albuminous-vitamin-mineral additive Immovit in combination with an extract of hill-growing saltwort there was stated the improvement of swine slaughter product quality. In products from the animals which were administrated with a complex of examined preparations there was stated an optimized moisture content, the increasing of a relative biological value of a product (101,3-103,8%), and according to the indexes of bacterial safety the experimental pork considerably surpassed the meat indexes from animals of control groups. At the same time, in slaughter animal products of control groups there were revealed coliform bacillus bacteria.

In the conditions of the Republic of Belarus as a result of task-specific selection and breeding work there was developed and approbated Berezinsky breed type of Belarusian meaty breed. Sows of the studied breed type were notable for high indices of reproductive signs: the average multiple pregnancy in three breeding swine herd was 11,1 pigs per farrowing; milkability - 55 kg, litter size at weaning stage at 35-day age - 87,1 kg. The predominancy over the forecast exponent indices made 4,7-5,7%. In course of the study there were analyzed the forecasted indexes of the basic breeding signs of Berezinsky breed type of Belarusian meaty breed for 2005-2010; productivity indices of the experimental sows; coefficient of variations of sow productivity.

In the conditions of the Republic of Belarus there was studied the influence of methods and means of spot heating and localization of warmth on indexes of microclimate in piglet breeding houses and resting area of piglets and their growth parameters. In course of the study there taken into consideration the indexes of an average temperature on piglet resting area housings; atmosphere relative humidity, air velocity, content of carbon dioxide, content of hydrogen nitride in the housing and resting areas of piglets. Research results of microclimate of swine breeding areas and resting areas of piglets under different means and methods of heating and warmth localization showed that the it was the most efficient to add for the local heating in the first three weeks of suckling period the glow-discharge tubes or in suckling period or weanling periods - the heated floors; and in suckling period - brooders in the form of tops with shields.

In the conditions of the Republic of Belarus there was studied the morphology and growth dynamics of vomeronasal cartilage of swine at postnatal period. The vomeronasal cartilage covers the vomeronasal body outside. Lateral and medial bases of vomeronasal cartilage formed an antrum in which there was an organon vomeronasal. The most intensive growth of a cartilage of pigs occurred in the first two months of animal life. Arrangement of cartilage was dissymmetric - at the right it was sited more caudad than at the left; this fact caused the differences in its dimensions at the transverse sections.

In the conditions of the Republic of Belarus there was analyzed the influence of mycotoxins on state of energy metabolism and development of energy deficient states of bred and milking sows maintained in the production breeding conditions. Clinical status of sows was characterized by concurrent mycotoxicoses. As a result of action of mycotoxins in sows there was developed an energy deficiency and state of acidosis. The mentioned above changes played an important part in the pathogenesis of mycotoxicosis. There were presented the following results: analysis of groups of pregnant sows and suckling-pigs; the content of mycotoxins in mixed fodders; symptoms revealed at sows and pigs; indexes of carbohydrate and lipide exchanges in blood of sows; the content of trace elements in blood of sows; gas composition of sow blood. | Исследования проведены на супоросных и подсосных свиноматках, содержащихся в условиях промышленной технологии. Клинический статус свиноматок характеризовался сочетанным микотоксикозом. В результате действия микотоксинов у свиноматок развились энергодефицит и состояние ацидоза. Данные изменения являются важной составной частью патогенеза при микотоксикозах. В табличной форме представлены группы супоросных и подсосных свиноматок, содержание микотоксинов в комбикормах, симптомы, выявленные у свиноматок и поросят, показатели углеводного и липидного обменов в крови свиноматок, содержание макроэлементов в крови свиноматок, газовый состав крови свиноматок.

As a result of realized in the conditions of the Republic of Belarus research it was revealed that application of immunostimulative drugs of sodium thyosulphate and vitamin С (ascorbic acid) in combination with a vaccine against salmonellosis, pasteurellosis and streptococcosis of pigs promoted the statistically authentic increasing of leukocytes, absolute quantity of T- and B-lymphocytes content in peripheral blood. Also, it promoted the activation of phagocytic activity and digested ability of neutrophils; activization of mieloblastic hemopoiesis and decreasing of erythrocytopoiesis; activization of morphological reactions in a tissue at a place of administration of the vaccine, lymphatic nodules and spleen. | Проведенные исследования показали, что применение иммуностимуляторов натрия тиосульфата и витамина С с вакциной против сальмонеллеза, пастереллеза и стрептококкоза свиней способствует статистически достоверному повышению в периферической крови содержания лейкоцитов, абсолютного количества Т- и В-лимфоцитов, активизации фагоцитарной активности и перевариваемой способности нейтрофилов; активизации миелобластического кроветворения и снижению эритропоэза; активизации морфологических реакций в ткани на месте введения вакцины, лимфоузлах и селезенке.

Belarus concerns a biogeochemical province with the lowered content in environment of such microelements, as iodine, selenium, copper, cobalt, manganese, zinc and some other. It conducts to infringement of intensity and an orientation of processes of an exchange of proteins, carbohydrates, lipids, and finally - to decrease in their growth and development of an organism of young growth. High cost of foreign preparations for treatment and preventive maintenance of an alimentary anaemia, low bioavailability of iron and toxicity do not provide purposeful disesase control and immunodeficiencies arising on its background. The special urgency is got by research of means of complex preventive maintenance of an alimentary anaemia and immunodeficiencies. It has been established that the recipes N1-3 have proved to be non-toxic for laboratory animals and have no effect on the meat quality.

In the conditions of the Republic of Belarus there was determined the parasitizing influence of Oesophagostomum and their larvae on a metabolism of experimentally infested animals. In course of the study there were generated experimental and control groups of two-month old piglets. Animals of the experimental group were infested in a dose of 15000 invasion larvae per one kg of body weight. Animals of the control group were not infested. Infestation was realized through a mouth with invasion larvae with wet forage. Invasion larvae received by cultivation of excrement tests from infested pigs at temperature of 24 deg C. As a result of the realized research it was established, that Oesophagostomum invasion rendered a substantial influence on the experimental animals. At bimestrious pigs after the experimental infection with Oesophagostomum larvae there were stated the following changes: the disease on 4-30th day was characterized by frustration of function of a gastroenteric path - diarrhea, fever, anaemia, and in the subsequent - stagnation and juvenilism of animals. Oesophagostomum in a host organism caused the pathological changes of haemotological and biochemical blood value which were expressed in quantity decrease of erythrocytes, concentration of haemoglobin, leucocytosis. Eosinophilia was observed in a leukogram. In blood serum there was stated the lowering of crude protein and its fractions content; gradually, but authentically there was noted the increasing of activity serum glutamic oxalacetic transaminase and glutamic-pyruvic transaminase. Bactericidal and lysozymic activity of blood serum decreased. Activity of alkaline phosphatase increased.

In the conditions of the Republic of Belarus there was studied the influence of herbal infusion, tincture, liquid and dry extracts of elecampane (Inula helenium) on morphological and biochemical indexes of pig blood. In course of the study it was established, that preparative forms of elecampane stimulated the formation of blood corpuscle, and also increased of the hemoglobin level in blood of pigs. Administration of elecampane preparations did not cause any authentic changes in blood leukogram of swine; all indicators were within normal limits. Elecampane preparations did not cause changes on the part of biochemical blood indexes of and did not influence the activity of enzymes. Research results showed that herbal infusion, tincture, liquid and dry extracts of elecampane did not render negative influence on swine.
