The effect of probiotics on the Californian rabbits' productivity

Against the background of an increase in allergic diseases in humans, the issue of safety and bioavailability of meat products is very relevant today. The diversity of the biochemical composition of rabbit meat and the high percentage of its nutrients' digestibility by the human body determines the value of rabbit meat. In this regard, the study of the issues of increasing the rabbits' productivity is relevant. The aim of the work was to study the effect of the Bio-Mos probiotic on the productivity of Californian rabbits.The study was conducted on the basis of the FSBEI HE SAU of the Northern Trans-Urals and on the basis of the rabbit breeding complex of CJSC APPK "Roshchinsky" of the Tyumen region. The object was male rabbits at the age of 4 months. 2 groups were formed: control (regular diet), experimental (regular diet + Bio-Mos probiotic at a dose of 2 g per kg of granulated feed). Further, the stomach contents of rabbits were evaluated; biochemical analysis of muscle tissue samples, slaughter yield, organoleptic and microbiological indicators of meat were carried out. The studies revealed a positive effect on the digestibility of nutrients (fiber, copper, and zinc), as well as on the slaughter yield (an increase of 2.5%), an increase in the amount of protein (18.30± 0.19g/100g), fat (8.5±0.64g/100g) and the energy value of meat (647.90±6.59kJ/100 g). All this indicates an increase in productivity against the background of introducing Bio-Mos into the diet due to stabilization of the digestive system

Titrimetric determination of primary, secondary, and tertiary amino groups in amine epoxy hardeners

Procedures are proposed for the determination of primary, secondary, and tertiary amino groups in polyethylenepolyamine. In these procedures, the products that formed in the reaction of polyethylenepolyamine with acetic and maleic anhydrides in a mixture of water and an organic solvent are titrated with an aqueous solution of an acid using the potentiometric or visual detection of the titration end-point. The procedure does not require prolonged heating of the reagents at the stage of sample preparation; pyridine and acetic acid are not used in the analysis. © 1998 MAEe cyrillic signK Hayκa/Interperiodica Publishing

Safety in the structure of values of young people living in an urban environment

The article presents a study of psychological safety in the structure of values of young people living in an urban environment. Also, the gender factor was taken into account to understand young people’s social expectations and as an explanatory framework for the individual fate of each person. The results show that in both young men and women the value of safety is built into the very value context that is fundamental for young people at a certain stage of their life. These studies show that it is a sense of safety that creates real opportunities to meet the natural and social needs of the present and provides grounds for confidence in the future

Comparative analysis of the efficiency of the application of domestic and foreign mixed fodders for sturgeon and catfish

The conducted studies have revealed the possibility of replacing imported mixed fodders with domestic analogues and obtaining cash savings in the production of high-quality fish products. A comparative analysis of domestic and foreign mixed fodders for sturgeon and catfish showed significant similarity in nutritional value. Saving money, taking into account the growth of fish when using domestic mixed fodder with the addition of a suspension of chlorella, rapeseed cake and safflower cake, amounted to 15,01 BYN per 1 kg of growth of juvenile Lena sturgeon and 1,04 BYN per 1 kg of growth of juveniles of African catfish in comparison with imported mixed fodders manufacturers «Le Gouessant» and «Aller Aqua» respectively.Проведенные исследования выявили возможность замены импортных комбикормов отечественными аналогами и получения экономии денежных средств при производстве качественной рыбной продукции. Сравнительный анализ отечественных и зарубежных комбикормов для осетровых и сомовых рыб показал значительное сходство по питательности. Экономия денежных средств с учетом приростов рыб при использовании отечественного комбикорма с добавлением суспензии хлореллы, жмыхов рапса и сафлора составила 15,01 BYN на 1 кг прироста молоди ленского осетра и 1,04 BYN на 1 кг прироста молоди клариевого сома по сравнению с импортными комбикормами производителей «Le Gouessant» и «Aller Aqua» соответственно

Growing young catfish (Clarias gariepinus Burchell) with the application of mixed fodders with suspension of chlorella and oilseed crops cake

Aquaculture is based on the use of compound feed, which accounts for about 70–80% of costs. Due to their biological needs, metabolic characteristics and habitat, fish are more demanding on the quality of feed, the main suppliers of which in the Republic of Belarus are foreign firms. This leads to an increase in the cost of production and significantly hinders the development of aquaculture, therefore, when developing formulations of domestic mixed feeds for juvenile fish of valuable species, it is necessary to rely on the use of inexpensive, affordable and effective components. In the aquaculture of Belarus, one of the promising species for industrial production is the African catfish (Clarias gariepinus Burchell). High food plasticity makes it possible to grow it under industrial conditions, for example, in recirculating water systems, on the same artificial feed. It is known that the addition of algae to feed contributes to the normalization of metabolic processes in fish, accelerates the growth of natural beneficial microflora during digestion and strengthens the body’s immune system. On the basis of this, experimental compound feeds for juvenile African catfish were developed with the addition of chlorella, rapeseed cake and dyeing safflower to the suspension. A chemical analysis of the experimental and control feed was carried out, which revealed the ability of the developed feed to meet the needs of fish in basic nutrients on a par with the control feed. The results of growing African catfish using an experimental compound feed (KS + 3% rapeseed + 3% safflower + 3% chlorella suspension) indicated an increase in absolute and relative growth rates, as well as a decrease in the feed ratio, which made it possible to obtain the best economic effect among the applied compound feeds. This indicated the possibility of effective use of the developed compound feed with the addition of a suspension of chlorella and rapeseed and dyeing safflower cake as a full-fledged replacement for imported compound feed.Аквакультура базируется на использовании комбикормов, которые составляют около 70–80% затрат. В силу своих биологических потребностей, особенностей метаболизма и среды обитания рыбы более требовательны к качеству комбикормов, основными поставщиками которых в Республике Беларусь являются зарубежные фирмы. Это ведет к удорожанию продукции и значительно сдерживает развитие аквакультуры, поэтому, разрабатывая рецептуры комбикормов отечественного производства для молоди рыб ценных видов, необходимо опираться на использование недорогих, доступных и эффективных компонентов. В аквакультуре Беларуси одним из перспективных видов для промышленного производства является африканский (мраморный) клариевый сом (Clarias gariepinus Burchell). Высокая пищевая пластичность позволяет выращивать его в индустриальных условиях, например в УЗВ, на одних искусственных кормах. Известно, что добавки водорослей в корма способствуют нормализации обменных процессов у рыб, ускоряют рост естественной полез-ной микрофлоры желудочо-кишечного тракта укрепляют иммунную систему организма. На основании этого разработаны опытные комбикорма для молоди клариевого сома с введением в состав суспензии хлореллы, жмыхов рапса и сафлора красильного. Проведен химический анализ опытных и контрольного комбикормов, выявивший способность разработанных комбикормов удовлетворять потребности рыб в основных питательных веществах наравне с контрольным комбикормом. Результаты выращивания клариевого сома с применением опытного комбикорма (КС + 3% рапса + 3% сафлора + 3% суспензии хлореллы) свидетельствовали об увеличении абсолютного и относительного приростов, а также о снижении кормового коэффициента, что позволило получить наилучший экономический эффект среди применявшихся комбикормов. Это свидетельствовало о возможности эффективного применения разработанных комбикормов с добавлением суспензии хлореллы и жмыхов рапса и сафлора красильного как полноценной замены импортному комбикорму
