В статье приводятся результаты изучения аллельных вариантов гена каппа-казеина (k-cas) – AA, AB, BB в молоке у коров разных линий Вис Бэк Айдиал 1013415 и Рефлекшн Соверинг 198998 голштинской породы крупного рогатого скота. Были сформированы 6 групп коров третьей лактации по 15 голов в каждой по принципу аналогов аллельных вариантов каппа-казеина. Разница по 3-й лактации между коровами III группы (7060 кг) и остальными группами составила 307, 543, 270, 283 и 112 кг молока соответственно. По содержанию жира и белка в молоке разница составила в пределах 0,01–0,04% по группам. В связи с этим по количеству молочного жира разница была незначительная – в пределах 12,19–21,94 кг. Установлено, что наибольшая вариабельность (Cv%) характерна для удоя, затем величина коэффициента вариации последовательно убывает по массовой доле жира и белка в молоке. Наибольшая изменчивость по удою (15,37%) наблюдалась у коров IV группы. Связь между удоем и содержанием белка в молоке была положительная у животных всех групп (+0,07…+0,52), кроме коров VI группы (k-сas (BB)), у которых она была слабая отрицательная (–0,37). Отрицательная связь массовой доли жира и белка наблюдалась в молоке коров I, II, IV и V групп, а у животных III и VI групп она была положительной, но достоверной только у коров VI группы (Р > 0,95). В молоке коров всех подопытных групп установлена высокая положительная и достоверная связь между массовой долей белка и его основной фракцией – казеином.
The article presents the results of studying allelic variants of the kappa-casein (k-cas) gene – AA, AB, BB in milk in cows of different lines Vis Back Ideal 1013415 and Reflection Sovering 198998 of the Holstein breed of cattle. 6 groups of cows of the third lactation were formed, 15 heads in each according to the principle of analogues of allelic variants of kappa-casein. The difference in 3 lactation between cows of group III (7060 kg) and the rest of the groups was 307, 543, 270, 283 and 112 kg of milk, respectively. In terms of fat and protein content in milk the difference was within 0.01–0.04% by groups. In this regard, the difference in the amount of butterfat was insignificant – in the range of 12.19–21.94 kg. It was found that the greatest variability (Cv%) is characteristic of yield, then the value of the coefficient of variation consistently decreases in the mass fraction of fat and protein in milk. The greatest variability in yield (15.37%) was observed in cows of group IV. The association between yield and protein content was positive in animals of all groups (+0.07…+0.52), except for cows of group VI (k-cas (BB)), in which it was weakly negative (–0.37). A negative association of fat mass fraction and protein was observed in milk of cows of groups I, II, IV and V, and in animals of groups III and VI it was positive, but significant only in cows of group VI (P >0.95). In milk of cows of all experimental groups there was a high positive and reliable association between mass fraction of protein and its main fraction – casein.

Проанализирована скаковая карьера кобыл чистокровной верховой породы, несущих вариант Т/Т полиморфизма гена миостатина. Выявлено, что встречаемость такого типа полиморфизма у отечественного поголовья выше, чем у поголовья в других странах. Результативность испытаний кобыл с типом полиморфизма Т/Т более высока в трёхлетнем возрасте и на дистанциях свыше 1600 м. Из 19 скакавших лошадей побед добивались 7, а призовых мест – 11, но только две кобылы побеждали несколько раз и 6 кобыл имели в карьере несколько призовых мест. В результате проведённого анализа становится понятно, что большинство (более 63%) лошадей, несущих гомозиготный вариант Т/Т, выдерживают многолетнюю ипподромную эксплуатацию с достаточно высокой её результативностью. Возможно также, что импортированные лошади, в силу большего присутствия в родословных кровей фляеров, имеют преимущество на скаковой дорожке, поскольку обладают выраженными резвостными качествами. Как известно, стайер без предрасположенности к резвостным броскам – самая бесперспективная для скакового использования лошадь, так как обладает только выносливостью, без способности делать резвые броски по дистанции и на финише. Скаковой класс кобыл с вариантом полиморфизма Т/Т раскрывается в старшем возрасте и на дистанциях более 2000 м. Так, более значимые совокупные за карьеру призовые суммы (от 150000 до 1760000 рублей) получены при выступлениях в призах на удлинённые дистанции – 2000 и более метров.
The racing career of Thoroughbred mares carrying the T/T variant of the myostatin gene polymorphism was analyzed. It was revealed that the occurrence of this type of polymorphism in domestic livestock is higher than in livestock in other countries. The test performance of mares with the T/T type of polymorphism is higher at the age of three and at distances over 1600 m. Of the 19 horses that raced, 7 achieved victories and 11 won prizes, but only two mares won several times and 6 mares had several winning places in their careers. As a result of the analysis, it becomes clear that the majority (more than 63%) of horses carrying the homozygous T/T variant withstand long-term of racetrack use with fairly high performance. It is also possible that imported horses, due to the greater presence of flyer blood in the pedigrees, have an advantage on the racing track, since they have pronounced agility qualities. As you know, a stayer without a predisposition to make quick throws is the most unpromising horse for racing use, since he only has endurance, without the ability to make quick throws along the distance and at the finish line. The racing class of mares with the T/T polymorphism variant is revealed at an older age and at distances of more than 2000 m. Thus, more significant total prize sums during a career (from 150000 to 1760000 rubles) were received when competing in prizes at extended distances – 2000 meters or more.

Предложен комбинированный агрегат обработки почвы и посева, обеспечивающий оптимальное размещение семян в почве. Важным элементом устройства размещения семян является перфорированная труба. В результате расчётов и пространственного моделирования ранее были выявлены зависимости: количества драже между первым и вторым сбрасывателем от наружного диаметра перфорированной трубы, максимального количества отверстий от наружного диаметра перфорированной трубы, исходя из геометрии перфорированной трубы и возможного количества драже между первым и вторым сбрасывателем. На основании проведённых исследований предварительно определён оптимальный наружный диаметр, количество отверстий в поперечном сечении перфорированной трубы и угол между осями этих отверстий. Ранее путём моделирования и расчётов установлена корреляция скорости агрегата с диаметром перфорированной трубы при безударном попадании драже в отверстие перфорированной трубы. Однако для правильной конструктивной компоновки высевающего устройства следует рассмотреть другие варианты. Поэтому рассчитаны параметры оптимального посева семян при небезударном контакте драже со стенкой отверстия и выведены зависимости параметров от наружного диаметра перфорированной трубы.
A combined tillage and sowing unit has been proposed, which ensures optimal placement of seeds in the soil. An important element of the seed placement device is the slotted pipe. As a result of calculations and spatial modeling, the dependencies were previously identified: the number of dragee between the first and second tripper diverter on the outer diameter of the slotted pipe, the maximum number of holes from the outer diameter of the slotted pipe, based on the geometry of the slotted pipe and the possible number of dragee between the first and second tripper diverter. Based on the research carried out, the optimal outer diameter, the number of holes in the cross-section of the slotted pipe and the angle between the axes of these holes were preliminarily determined. Earlier, by modeling and calculations, a correlation of the speed of the unit with the diameter of the slotted pipe was established in case of non-impact hit of dragee into the hole of the slotted pipe. However, other options should be considered for proper design of the seeding device. Therefore, the parameters of optimal sowing of seeds for non-impact contact of the dragee with the wall of the hole were calculated and the dependences of the parameters on the outer diameter of the slotted pipe were derived.

В статье представлен разработанный авторами фильтр с полимерными элементами, имеющий микроконтроллерную систему, которая управляет выходной частотой ультразвукового генератора и питает блоки многослойных преобразователей. Частота механического резонанса колебательной системы зависит от многих параметров и меняется в процессе работы. Со временем фильтрующие элементы забиваются, теряя эффективность очистки масла. Поэтому фильтрующие элементы заменяются новыми. Для обеспечения высокой эффективности частота очистки фильтра должна постоянно контролироваться и настраиваться на резонансную частоту. Применение микроконтроллерной системы позволит управлять ультразвуковым преобразователем, отправляя пакеты импульсов с частотой 30 кГц, для обратной связи применяется датчик ультразвука HC-SR04. Данный датчик необходим для контроля передачи преобразователем ультразвуковых колебаний. В приведённых расчётах по преобразователю ультразвуковых колебаний резонансная частота будет составлять 35,5 кГц, что соизмеримо с частотой передачи импульсов микроконтроллера.
The article presents the filter with polymer elements developed by the authors, having a microcontroller system that controls the output frequency of the ultrasonic generator and feeds the blocks of sandwich transducers. The frequency of mechanical resonance of the oscillating system depends on many parameters and varies during operation. Over time, the filter elements become clogged, losing the efficiency of oil cleaning. Therefore, the filter elements are replaced with new ones. To ensure high efficiency the filter cleaning frequency must be constantly monitored and tuned to the resonant frequency. The use of a microcontroller system will allow you to control the ultrasonic transducer by sending pulse packets at a frequency of 30 kHz, a HC-SR04 ultrasound sensor is used for feedback. This sensor is necessary to monitor the transmission of ultrasonic vibrations by the transducer. In the calculations given by the ultrasonic oscillation transducer, the resonance frequency will be 35.5 kHz, which is commensurate with the pulse transmission frequency of the microcontroller.

PARASITIC DISEASES OF FISH IN THE CONDITIONS OF FARMING PONDS OF "AQVAREST" AND "AQUACITY" LLC IN THE ODESSA REGION
Authors: Bogach М. , Panikar V. 
Published: November 2023

The article provides data on the spread of parasitic diseases in carp and grass carp in the farming ponds of Aqvarest LLC and Aquacity LLC of the Odesa region. Fish diseases are registered both in natural reservoirs and in fish farms, as a result of which the growth rates, reproductive capacity, marketability of fish decrease, quality indicators and biological value deteriorate; in addition, mass kills of fish may occur. The causes of diseases can be both non-contagious (adverse environmental conditions) and contagious (viruses, bacteria, parasitic diseases). Thus, constant monitoring of fish parasitofauna in pond farms of Ukraine is necessary, since the study of patterns of occurrence and spread of fish diseases, forecasting of these diseases affects the effectiveness of aquaculture breeding and preservation of fish products.
The purpose of the work was to monitor parasitic diseases in carp and white amur in the farming ponds of Aqvarest LLC and Aquacity LLC of the Odesa region.
During the parasitological examination of this year's and two-year-old carp and white amur in the ponds of LLC "Aqvarest" and LLC "Aquasti" of Odesa region, five diseases were diagnosed, the causative agents of which were: Gyrodastylus birmani, Dactylogyrus vastator, Khavia sinensis, Caryophyllaeus fimbriceps and Philometroides lusiana.
Gyrodastylus birmani and Caryophyllaeus fimbriceps were recorded the most in the deep pond of "Aqvarest" LLC with the extent of invasion of 25.7%, in two-year-old carp and two-year-old white amur - 21.4%. In the shallow reservoir of "Aquacity" LLC, Gyrodastylus birmani (31.4%) and Caryophyllaeus fimbriceps (25.7%) were most recorded in two-year-old carp, and in two-year-old white amur Khavia sinensis (28.5%) and Caryophyllaeus fimbriceps (32.1 %).
The intensity of infestation with cestodoses (caviasis and caryophyllosis), as well as nematodes (phyllometroidosis) was low, 1-2 or 3-4 specimen for fish, and clinical manifestations of the disease were not always recorded. However, the presence of these pathogens in the fauna represents a significant danger for the development of commercial fish species, namely carp and white carp.

In the article a literature review related to the etiology, epizootology, pathogenesis, clinical symptoms of endometritis in cows and modern means of its etiotropic therapy is provided. Postpartum endometritis is considered one of the most common diseases in cows, causing great economic losses to dairy operators, due to the increase in the number of unfertilized cows after repeated artificial insemination, the increase of the service period and the percentage of culled cows, treatment costs, decrease in milk yield, etc.
The main role in the etiology of endometritis in cows in the postpartum period is assigned to bacterial opportunistic microflora. In the etiology of endometritis, the basic role is played by Staphylococcus spp., Streptococcus spp. and Escherichia coli. Other bacteria can cause endometritis in cows, such as: Actinomyces pyogenes, Fusobacterium necrophorum, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Prevotella spp., Bacteroides spp. In many cases, acute postpartum endometritis in cows is caused by the association of microorganisms, especially Escherichia coli with streptococci and staphylococci.
Microorganisms penetrate the mucous membrane of the uterus, their toxins and enzymes destroy nerve endings and capillaries, what leads to a reaction in the form of an inflammatory process, what is localized mainly in the surface layers of the endometrium and in the inter-glandular connective tissue. The development of endometritis depends on the immune response of the cow, as well as on the type and number of bacteria that colonize the endometrium.
According to the kind of the inflammatory process, endometritis in cows are classified into: purulent; serous; catarrhal; serous-catarrhal; fibrinous; catarrhal-purulent. According to the passing of the disease, endometritis are acute, subacute, less often - chronic.
Diagnosis of endometritis includes collection of anamnestic data, general clinical exploring of the animal and special gynecological (vaginal and rectal) testing.
The basis of the treatment of endometritis in cows is etiotropic therapy, what involves by the use of antimicrobial drugs that affect the cause of the disease, and is used to stop the reproduction of opportunistic microflora in the uterine cavity and normalize the microbiocenosis. For the etiotropic therapy of endometritis in cows, drugs for intrauterine administration and drugs for systemic treatment in the form of a solution or suspension for injections are used.
