В табличной форме представлены данные по активности аланинаминотрансферазы (АлТ), аспартатаминотрансферазы (АсТ), щелочной фосфатазы (ЩФ) в печени, поджелудочной железе и сыворотке крови ремонтного молодняка кур, вакцинированных против ИЛТ

There was studied the influence of parasites on quantitative and qualitative characteristics of gastrointestinal microflora of animals. The digestive path represents open system by means of which contact of macroorganism to environment and present at it microbes is carried out. For normal functioning of digestive system the essential role is played by its microbiocenosis condition. During the research some regularities in the rumen and intestine microflora content under the influence of parasites (e.g. N. vitulorum and in assotiation with Eimeria spp. and Strongylata spp) have been postulated. They are expressed by quantity reduction of bifido- and lactoflora with simultaneous increase of content of conditional-pathogenic intestinal stick, aerobic bacillus and micromicet; decrease of quantitative and qualitative structure of protozoa rumen, decrease in their mobility, and also decrease in activity of cicatricial microflora. | Целью работы является изучение влияния паразитов на количественную и качественную характеристики микрофлоры желудочно-кишечного тракта животных. Пищеварительный тракт представляет собой открытую систему, посредством которой осуществляется контакт макроорганизма с внешней средой и присутствующими в нем микробами. Для нормального функционирования пищеварительной системы существенную роль играет состояние ее микробиоценоза. В ходе исследований установлены определенные закономерности в изменении микробиоценоза рубца и кишечника под влиянием паразитарных агентов у телят (а именно, при паразитировании Neoascaris vitulorum в виде моноинвазиии или в ассоциации с Eimeria spp. и Strongylata spp.), которые выражаются уменьшением количества бифидо- и лактофлоры с одновременным увеличением содержания условно-патогенной кишечной палочки, аэробных бацилл и микромицет; нарушением количественного и качественного состава простейших рубца, снижением их подвижности, а также снижением активности рубцовой микрофлоры.

There was studied the features of intra-bodies vessels of turkey thymus of white breed during postnatal ontogenesis. Results of the anatomic and histologic research which allowed to study law of transformations of intra-bodies vessels of turkey thymus are reflected. It is established, that age reorganisation of intra-bodies vessels of turkey thymus is interfaced to development of the basic structural body components. The microvascular thymus channel at the expense of presence hemato-thymus barrier accepts active participation in separation of blood and blood-groove regulation in parenchyma. The maximum factor of thymus blood supply of turkeys is noted in 70 days. Before puberty there is a growth of intra-bodies vessels at the expense of increase in their diameter and a thickness of a wall (mainly media), and after 220 days the haemodynamic potential of body decreases owing to increase of the involutional processes characterized by reduction of vesseldiameter and a thickening of their wall for the account of adventition. In the tabular form the sizes of intracapsular thymic vessels, the sizes of interlobular thymic vessels are presented. | Цель исследования - изучить особенности интраорганных сосудов тимуса индеек белой широкогрудой породы в постнатальном онтогенезе. Отражены результаты анатомических и гистологических исследований, позволивших изучить закономерности преобразований интраорганных артерий тимуса индеек белой породы в период постнатапьного онтогенеза. Установлено, что возрастная перестройка интраорганных артерий тимуса индеек сопряжена с развитием основных структурных компонентов органа. Микрососудистое русло тимуса за счет присутствия гематотимусного барьера принимает активное участие в сепарации крови и регуляции кровотока в паренхиме. Максимальный коэффициент кровоснабжения тимуса индеек отмечен в 70 суток. До полового созревания происходит рост интраоганных артерий за счет увеличения их диаметра и толщины стенки (преимущественно медии), а после 220 суток гемодинамический потенциал органа снижается вследствие нарастания инволюционных процессов, характеризующихся уменьшением диаметра артерий и утолщением их стенки за счет адвентиции. В табличной форме представлены размеры интракапсулярных артерий тимуса, размеры междольковых артерий тимуса.

Belarus is among regions, where the selenium content in soil, hence, in cereal and other cultures considerably below requirements that leads to insufficiency of this microelements in a diet as the person, and animals. Synthesized in the All-Russian Scientific Research Institute of Physiology, Biochemistry and Feeding of Agricultural Animals new organic compound of selenium - selenopyran on variety of criteria has no analogues in the world among considerable quantity selenium of containing preparations and favourably differs from all known forms of microelements. Selenopyran, brought in fats and forages, shows antioxidatic the properties which are not conceding traditionally applied in veterinary science and medicine to antioxidants. Arriving in animal body with forage or in the form of injections, selenopyran is capable to play a role of a metabolic regulator. It activates enzymes of antioxidatic body protection, reduces formation new and will neutralize of earlier formed activeproducts of peroxide lipids oxidations, improves functioning of cellular membranes, normalizes metabolism, makes active cellular, humoral and phagocytal immunity links, raises nonspecific resistance and efficiency of animals. Toxicity of selenopyran more low, than at all known organic connections of selenium, and more than in 100 times is less, than at sodium selenit. The data allow to expand possibilities of application of organic selenium and to use it as a preparation raising resistance and body viability at the expense of the patronage of cellular structures from influence of oxidizers and free radicals, to normalize metabolism and to stimulate thus the big additional body weight at animals. The influence of medicine organic selenium on piglet bodies what are behind a growth and development is shown. The results showing the dynamical changes of haematologicals, physiologicals and biochemicals indices under the influence of selenopyran was given.

The use of low intensive red spectrum laser radiation for prevention of abomasoenteritis in calves is effective method. As a result the increase of erythrocytes level and saturation of them with hemoglobin happens. Natural resistance with bactericide and lysozyme activity are going up phagocytosis of neutrophils is activated. The most successful method are magnet-laser radiation of blood and laser acupuncture. There was studied the low intensive red spectrum laser radiation for prevention of abomasoenteritis in calves. During the research it is established, that preventive efficiency at abomasoenteritis in the first trial group has made 80%, in the second and the third - 90%. As a result of the spent work high preventive efficiency of action of the low intensive red spectrum laser radiation is established at prescription of through-skin blood irradiations by the therapeutic laser in a combination to a constant magnetic field and as a result influences on biologically active points. Application of these ways allows to reduce level of disease of animal abomasoenteritis. As a result of physiotherapeutic influence there is content increase of erythrocytes in blood of calves and saturation their haemoglobin. Natural resistance with bactericide and lysozyme activity are going up phagocytosis of neutrophils is activated. The most successful method are magnet-laser radiation of blood and laser acupuncture. It is caused by that positive changes occurring in an organism, have been more brightly expressed and besides preventive and economic efficiency of these ways of irradiation also were at higher level.
