Contribution of some immunological and metabolic factors to formation of piglets’ post-vaccination immunity
The role and responsibility of natural resistance factors, protein and lipid metabolism in the formation of piglets post-vaccination immunity against circovirus is researched. Blood was taken for tests before and on the 15th, 40th and 70th day after the vaccination. The sampled blood was analyzed to determine immunological and biochemical parameters. It was revealed that before vaccination, 31.46% of the studied samples have a positive reaction in ELISA; their number increases to 67.80–71.16% on the 40th and 70th days after vaccination.In the blood of piglets, especially on the 40th and 70th day after the vaccination, the total count of leukocytes, monocytes and lymphocytes increases by 1.21; 2.28 times and 1.48 times, but neutrophils reduced by 1.74 times along with the phagocytic properties activation. The anabolic directivity of protein metabolism is defined by the synthesis of globulin proteins. At the same time albumin-synthesizing activity in a liver decreased and “cytolysis reaction” of hepatocytes was detected. In the lipid profile of piglets’ blood, the content of LDL‑cholesterol increased by 1.44 times, while that of triglycerides decreased by 2.64 times. X‑ray spectral analysis revealed the correlation between the formation of post-vaccination immunity and two factors: the factor of the principal component (PC) 1, which is predominantly associated with indicators of natural resistance, and PC2, which is associated with metabolism indicators. The research results show that in order to increase the efficiency of formation of post-vaccination immunity in piglets, it is necessary to combine vaccination with hepatoprotective drugs

Pathological features of the lungs and liver of piglets under conditions of constant vaccination of livestock against circovirus infection
The pathogenicity of PCV 2 in the body of vaccinated piglets was studied based on the results of pathomorphological changes in the lungs and liver of animals. The work was carried out on commercial piglets vaccinated with the vaccine Ingelvak CircoFLEX (Germany) against circovirus. The work used clinical, zootechnical, enzyme immunoassay and pathomorphological research methods. It has been established that under the conditions of ongoing vaccination of piglets against PCV2, 30.3% of piglets still do not have virus-neutralizing antibodies. The main reason for the culling of animals are circovirus diseases that have respiratory clinical signs, as well as signs of multisystem wasting syndrome, determining the safety of the livestock at the level of 68.05%, the average live weight of 1 head at the moment of its transfer for fattening is 40.44±0.78 kg, and the average daily gain in live weight is 346.00±9.18 g. At autopsy, sick piglets reveal an increase in the lungs and liver, and the signs of inflammation in them, as a result of circulatory disorders, damage to the lymphoid tissue, the development of dystrophic and necrotic changes. The results of the research suggest that in order to increase the efficiency of the formation of post-vaccination immunity, specific medical preparations can be used to stimulate the immune response of the body, as well as to enhance the resistance of the lymphoid tissue of the lungs and liver in animals.The pathogenicity of PCV 2 in the body of vaccinated piglets was studied based on the results of pathomorphological changes in the lungs and liver of animals.

The influence of brood chickens by-products processing with probiotic culture starter on change of their functional and technological parameters.
By-products are the potential source of animal protein obtained from brood chickens and egg-laying hens. Certain by-products like gizzards and combs are quite tough and possess low nutritional and biological value due to their high content of connective tissue. Biotechnological processing improves the quality parameters of collagen-containing by-products. In this article a probiotic starter culture of propionic acid bacteria, which have high proteolytic activity, was used to treat the gizzards and combs of brood chickens. Before processing of by-products with starter culture, physical and chemical parameters and the yield of by-products in relation to poultry live weight were analyzed and recorded. 5%, 10% and 15% starter culture were added to the tested samples of chopped by-products, the samples were kept at a temperature of 30 °C, and every 4 hours the following functional and technological parameters were monitored: moisture binding capacity, water holding capacity (MBC and WHC) and yield of the product after heat treatment. The results proved that increase of starter culture amount and longer exposure of by-products to hydrolysis led to decrease of functional and technological parameters values, but for the combs those parameters remained at a sufficiently high level compared to the gizzards, as the gizzards were exposed to more intense hydrolysis than combs. The decrease in the pH value correlated with the dynamics of MBC and WHC changes; and dynamics of the product yield after the heat treatment. Also the stained histological preparations were studied in order to assess the influence of biotechnological processing on by-products microstructure, where significant differences were found in the morphological structure of muscle and collagen fibers of hydrolysates of combs and gizzards exposed to action of bacterial concentrate. The results of rheological studies showed that hydrolyzed chicken combs differed from gizzards; the combs were denser and featured more elastic structure due to a lower degree of hydrolysis by bacterial enzymes. In general, the properties of collagen-containing by-products (muscular gizzards and combs) change significantly after being exposed to enzymes of propionic acid bacteria

New Nanostructured Carbon Coating Inhibits Bacterial Growth, but Does Not Influence on Animal Cells
An electrospark technology has been developed for obtaining a colloidal solution containing nanosized amorphous carbon. The advantages of the technology are its low cost and high performance. The colloidal solution of nanosized carbon is highly stable. The coatings on its basis are nanostructured. They are characterized by high adhesion and hydrophobicity. It was found that the propagation of microorganisms on nanosized carbon coatings is significantly hindered. At the same time, eukaryotic animal cells grow and develop on nanosized carbon coatings, as well as on the nitinol medical alloy. The use of a colloidal solution as available, cheap and non-toxic nanomaterial for the creation of antibacterial coatings to prevent biofilm formation seems to be very promising for modern medicine, pharmaceutical and food industries

продуктов животного происхождения с профилактическими свойства для экологически неблагоприятных регионов. Разработаны мясные биопродукты (с использованием конины, обработанной селезенки крупного рогатого скота, печени птицы, морской капусты) для профилактики заболеваний щитовидной железы, содержащие полноценные белки животного происхождения, а также комплекс витаминов, положительно влияющих на
организм человека. Решение проблемы снижения заболеваемости, вызванной
неблагополучной экологической обстановкой, возможно по двум направлениям:
улучшение экологической обстановки и создание новых продуктов питания
функционального назначения, позволяющих осуществлять коррекцию пищевого статуса, корректируя неблагоприятное воздействие окружающей среды. Создание
многокомпонентных продуктов функционального назначения является актуальной
задачей, решение которой имеет экологическое, научное и социальное значение для населения. Профилактическую направленность новым мясным продуктам придают, в основном, вводимые в рецептуры дополнительные источники белка животного и растительного происхождения, морепродукты, обладающие радиопротекторными
свойствами. Авторами выявлен не менее важный фактор, определяющий актуальность
поставленной проблемы, – необходимость обеспечения и контроля физиологической
ценности разрабатываемых продуктов питания с профилактическим эффектом. При
создании функциональных продуктов питания важная роль отводилась таким вопросам,
как медико-биологические требования к сырью и продуктам питания, основным и
составным компонентам разрабатываемого продукта, биологически активным добавкам,
придающим им направленность, сочетаемости компонентов, условиям приема продуктов.
Зарубежными и отечественными исследованиями установлено, что повышенный
неустойчивый радиационный фонд, попадание внутрь организма токсинов,
радиоактивных изотопов вызывают существенную перестройку белкового, минерального,
витаминного и других метаболических процессов в организме человека, а также приводят
к серьезным нарушениям важнейших для жизнедеятельности систем кроветворения и
пищеварения. Мировые тенденции в области питания связаны с созданием ассортимента
продуктов с профилактической направленностью, способствующих улучшению здоровья
при ежедневном их употреблении в составе рациона. The article describes the results of a study on the basis of food products of animal origin
for the preventive properties of ecologically unfavorable regions. Developed meat bioproducts
(using horse meat treated with bovine spleen, liver, poultry, seaweed) for the prevention of
diseases of the thyroid gland, containing complete proteins of animal origin, as well as a complex
of vitamins, has a positive influence on the human body. Solving the problem of reducing
morbidity caused by adverse environmental conditions, it is possible in two directions: improvement
of the environment and the creation of new food functionality, allowing for correction
of nutritional status, correcting adverse environmental effects. Creating a multi-product
functionality is an urgent task that has ecological, scientific and social significance for the
population. Preventative give new meat products, mainly incorporated in the formulation additional
sources of animal protein and vegetable, seafood, has radioprotective properties. The authors
identified no less important factor determining the urgency of the problem – the need to
ensure and monitor the physiological value of food developed with preventive effect. When
you create a functional food an important role was given to issues such as medical and biological
requirements for raw materials and food, basic and integral component of the developed
product, dietary supplements, give them orientation, compatibility of components, conditions
of reception products. Foreign and domestic research found that radiation increased the unstable
foundation Ingestion of toxins, radioisotopes cause substantial alterations of protein, minerals,
vitamins and other metabolic processes in the human body, but also lead to serious violations
of the most important for the life of hematopoietic system and digestive system.
Global trends in nutrition associated with the creation of a product range of preventive, contributing
to the improvement of health in daily use as part of their diet

свойств модельных фаршевых систем, обогащенных йодом. В рецептуру модельных фаршевых систем вводили морскую капусту, пищевую добавку «Ламинария» и «Йодактив». Проведен анализ результатов исследования степени влияния растительного компонента и пищевых добавок на изменение функционально-технологических характеристик готового продукта. Результаты эксперимента показали, что использование в соотношениях растительного компонента 0,05–0,10 % морская капуста; пищевых добавок ламинарии и йодактива 0,23–0,29 %; 0,48–0,55 %, соответственно, от рецептуры приводит к изменению ряда биотехнологических характеристик фарша по сравнению с контролем. Так, при введении жира до 10 % к массе обезжиренного мяса способность фарша удерживать влагу, жир и
его стабильность увеличивается благодаря образованию системы вода – белок – жир, в качестве стабилизатора которым выступает белок. При исследовании величины рН установлено, что, несмотря на изменение кислотности рН, изменение функционально-технологических свойств системы не произошло, что вызвано введением с растительным сырьем дополнительного количества катионов натрия, магния, фосфора, способных влиять на заряд белковой молекулы. При исследовании влияния добавок на водосвязывающую способность установлено, что уровень прочносвязанной влаги во всех опытных образцах был ниже по сравнению с контролем. Содержание прочносвязанной влаги в контрольном образце составило 79,4 %, а в опытных образцах всех вариантов от 72,4 до 73,5 %. При изменении рН жироудерживающая способность оказалась максимальной при его значении, равном 5. Это свидетельствует о том, что в кислой среде растительный компонент морской капусты и пищевых добавок имеют наибольшую удерживающую способность. Стабильность эмульсии достигает максимального значения при величине рН, близкой к 5,5. The paper presents the results of studying the functional and technological characteristics
of model forcemeat, enriched with iodine. Laminaria, food additive “Laminaria” and “Iodactiv” have been added during preparing the forcemeat. The results of the analysis of impact of plant and food additive on the functional and technological characteristics of the final product have been studied. The results show, that adding 0,05–0,10 % of laminaria, 0,23–0,29 % of food additive “Laminaria” and 0,48–0,55 % food additive “Iodactiv” leading to the change of some biotechnological characteristics of forcemeat comparing with the control sample. Thus, in adding until 10 % of fat to the nonfatted meat the capability of the forcemeat holds the moisture, fat and its stability increases through the creation of the system water-protein-fat,
where the protein is a stabilizer. While analyzing pH it is recognized, that notwithstanding the
change of pH the functional and technological characteristics has not been changed. This is
caused by introducing external amount of cations of sodium, magnesium, phosphorus which
are capable to influence on the charge of protein molecule. The impact of additive to the water
bound ability have been discovered. The level of bounded moisture in all test samples were below
the level of control sample. The content of bounded misture in the control sample was
79,4 %, but in all test samples were from 72,4 to 73,5 %. Due to pH change the fat holding capacity
has reached the maximul level at pH 5. This demonstrates that in acidic medium the
plant component of laminaria and food additives have their maximum holding capacity. Stability
of emulsions reached maximal level at pH close to 5,5
