Application of Vertical Electrical Sounding (VES) Resistivity Method to determine a well recommendation point at deep-groundwater exploitation
Authors: Taufiq Taufiq , Maharani Maharani , Mega H D
Published: April 2021

The demand of fresh water to develop of life community is very important, where almost all construction activities is required a water such as irrigating rice fields, building infrastructure, and to daily consumption. To obtain a good quality of groundwater, several parameter must be specified such as the depth of groundwater, thickness of the source, and resistivity value of rock. In this case, we try to applied Vertical Electrical Sounding (VES) resistivity method with Schlumberger configuration on one of Pamsimas Project to answer that parameter. VES Resistivity method is one of the active methods in geophysical study based on electrical properties of the subsurface rock by injecting electric current (I) into the earth and record the potential difference (?V) produced to the surface. From the results of current and potential difference measurements for each electrode spacing (AB/2) different then be lowered resistivity variations in the value of each layer below the measuring point (sounding points). After the acquisition on 3 points at Pandansari Village (PS-01, PS-02, PS-03), we get the result on PS-01, the water layer is indicated on the depth 60-80 meters with resistivity values equal than 36.7-50 ?m. On PS-02, the water layer is indicated on the depth 50-100 meters with resistivity values equal than 18.7-40 ?m. On PS-03, the water layer is indicated on the depth 30-60 meters with resistivity values equal than 52.8-70 ?m. Afterthat, we run 2D-pseudosection to know the distribution of groundwater layer in subsurface and get the thickness of groundwater is 20-50 meter with depth 40-80 meter. Based on this result, the PS-01 is the best point to make a well-exploitation on South Pandansari Pamsimas Project.
The Effect of Stress Distribution Around The Decline Shaft on The Support System Stability in Underground Mining
Authors: Pradani Diana Irmawati
Published: April 2021

The decline shaft is one of the main facilities in an underground mining work that is used as access to the mining panel from the surface. Making decline shafts on materials with weak characteristics is one of the important geotechnical issues that must be considered. The initial stage of making decline shaft holes is carried out on a relatively shallow ground surface or soil depth so that the horizontal stress that works is greater than the vertical stress. This excavation process will change the direction and magnitude of the initial stress from being in an equilibrium state to being disturbed. In addition to the stress on the rock mass, the condition of weak soil strength will affect the behavior and distribution of stresses working around the decline shaft hole. If the stress around the decline shaft exceeds the strength of the rock, there will be instability in the decline shaft so that strength is needed to control the existing stress.
Parâmetros de sensores em robótica móvel para exploração autônoma de ambientes internos
Authors:   , Vieira Flavio Barbosa
Published: April 2021

The area of mobile robotics has developed remarkably in recent years, many researchers are motivated by the growing demand for this technology and the variety of applications. Robotics competitions foster new challenges when considering diverse application scenarios for service robotics, such as RoboCup@Home, which sets rules for autonomous and intelligent robots to be evaluated while performing tasks in domestic or public scenarios. The present work focuses on solving the problem of exploring unknown residential indoor environments. To do this, the robot must collect external and internal information through sensors, to fuse this data and interpret it efficiently, making it possible to locate itself through probabilistic algorithms, simultaneously mapping the environment, and navigate the mapped environment avoiding collisions. The work studies and tests the configuration of distance sensors (lasers, sonar and cameras) and exploration techniques, available and shared in the ROS community, to ensure that the robot is able to fully explore the residential environment in order to optimize the necessary time, distance traveled and the rotation performed. The tested exploration packages are: explore-lite, RRT-exploration and cam-exploration. The variation of sensors was crucial to understand the advantages and disadvantages of using the Lidar laser and depth cameras in different combinations. Thus, the results show that the increase in the number of sensors does not improve performance in exploration in all conditions. The work concludes that both explore-lite and RRT-exploration perform well in all proposed conditions and indicate the best sensor assemblies for each package. Thus, a package was created for the implementation of autonomous exploration in the HERA Robot

Novel Processed Cheese Production Using Lycopene Oil Obtained By Green-Extraction Technique of Tomato Peels Waste
Authors: Bakry Amr
Published: April 2021

Extracted lycopene oil of tomato peels waste using green-extraction technique may be used as a convenient alternative to butter in processed cheese manufacturing. The effects of partial substitution of butter by lycopene oil at ratio of 25%, 50%, and 75% were evaluated, in comparison with cheeses produced only with butter. The substitution of butter by lycopene oil increased dry matter, ash, lycopene content, antioxidant activity, meltability and sensorial characteristics of processed cheese. While, the firmness value was decreased with increasing level of incorporated lycopene oil. The present study displays that the substitution of butter by lycopene oil obtained by green-extraction technique of tomato peels waste in processed cheese can be used as a substitute process for decreasing saturated fats in dairy products with keeping other desired characteristics of the product.

ABSTRAK. Terbitnya UU 21/2019 meningkatkan efektifitas sistem pengendalian sebaran HPIK. Sebelum UU ini diterapkan, potensi berpindahnya HPIK antar area tidak bebas HPIK cukup tinggi akibat diperbolehkannya komoditas perikanan carrier HPIK asymptomatic dilalulintaskan tanpa pengujian laboratorium sesuai regulasi pada saat itu. Hal ini menyebabkan upaya eradikasi di area tujuan tidak berjalan efektif disamping diinterpretasikannya “area bebas atau tidak bebas HPIK” hanya sebatas wilayah administratif membuka peluang berpindahnya HPIK dari area tujuan MP yang tidak bebas HPIK ke area lain disekitarnya yang masih bebas. Berdasarkan regulasi baru, setiap MP harus melalui penetapan bebas HPIK melalui pengujian laboratoris sebelum dilalulintaskan. Studi ini dilaksanakan untuk mengkaji resiko HPIK yang berpotensi terlalulintaskan bersama komoditas perikanan yang sering dikirim keluar dari Yogyakarta. Analisa dilakukan secara deskriptif melalui kajian tim analisa resiko HPIK lingkup SKIPM Yogyakarta dan desk study terhadap berbagai standar, peraturan perundangan terkait dan hasil berbagai penelitian temuan HPIK. Studi ini menunjukkan bahwa terdapat 12 penyakit viral dan 4 penyakit bakterial yang beresiko menyebar dari pintu pengeluaran Yogyakarta. Resiko tinggi mendominasi hasil penilaian HPIK dengan tingkat resiko barvariasi dari 18 hingga 25. Berbagai HPIK pada inang tertentu rata-rata merupakan target untuk sertifikasi dan pemantauan HPIK kecuali TILV dan RSIVD pada Gurami,VNN dan E. ictalurii pada Nila, CMNV pada Vannamei, WSSV Lobster tawar, YHD pada Udang Windu, dan E. ictalurii pada ikan Lele yang hanya merupakan target pemantauan; dan VNN pada Bandeng yang hanya sebagai target sertifikasi. Hasil analisa menjadi dasar penentuan target pengujian HPIK secara laboratoris terhadap komoditas perikanan yang akan dilalulintaskan dari Yogyakarta.

The novel COVID-19 disease, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus, apart from its respiratory complications and coagulopathy, is also involved in damage to other organ systems. We present a report of presumptive case of COVID-19 positive patient with no respiratory symptoms with superior mesenteric vein and portal vein thrombosis along with acute intestinal ischemia. The patient underwent exploratory laparotomy, resection of the ischemic bowel loops with proximal ileostomy and distal mucous fistula. The case highlights that despite the absence of respiratory symptoms, patients infected with SARS-CoV-2 may show atypical presentations, such as gastrointestinal symptoms.
Occult posterior inferior cerebellar artery dissection requiring endovascular treatment following pediatric head trauma: case report
Authors: Grover Patrick J , Harris Lauren , Qureshi Ayman M , Rennie Adam , Robertson Fergus , James Greg
Published: April 2021

This is the eighth case report of a pediatric dissecting posterior inferior cerebellar artery aneurysm. The authors present the case of a 13-year-old boy who presented with posttraumatic posterior fossa subdural, subarachnoid, and intraventricular hemorrhage with hydrocephalus. Initial vascular imaging findings were negative; however, a high level of suspicion is necessary. The aneurysm was identified on day 20, after recurrence of hydrocephalus, and was treated with endovascular vessel sacrifice. The patient made a good recovery. It is important to consider arterial dissection in pediatric traumatic brain injury, especially with suspicious findings on initial CT scan and clinical presentation out of proportion to the mechanism of injury. Delayed vascular imaging is imperative for appropriate management.
Late-week surgery and discharge to specialty care associated with higher costs and longer lengths of stay after elective lumbar laminectomy
Authors: Salas-Vega Sebastian , Chakravarthy Vikram B. , Winkelman Robert D. , Grabowski Matthew M. , Habboub Ghaith , Savage Jason W. , Steinmetz Michael P. , Mroz Thomas E.
Published: April 2021

OBJECTIVE

In a healthcare landscape in which costs increasingly matter, the authors sought to distinguish among the clinical and nonclinical drivers of patient length of stay (LOS) in the hospital following elective lumbar laminectomy—a common spinal surgery that may be reimbursed using bundled payments—and to understand their relationships with patient outcomes and costs.

METHODS

Patients ≥ 18 years of age undergoing laminectomy surgery for degenerative lumbar spinal stenosis within the Cleveland Clinic health system between March 1, 2016, and February 1, 2019, were included in this analysis. Generalized linear modeling was used to assess the relationships between the day of surgery, patient discharge disposition, and hospital LOS, while adjusting for underlying patient health risks and other nonclinical factors, including the hospital surgery site and health insurance.

RESULTS

A total of 1359 eligible patients were included in the authors’ analysis. The mean LOS ranged between 2.01 and 2.47 days for Monday and Friday cases, respectively. The LOS was also notably longer for patients who were ultimately discharged to a skilled nursing facility (SNF) or rehabilitation center. A prolonged LOS occurring later in the week was not associated with greater underlying health risks, yet it nevertheless resulted in greater costs of care: the average total surgical costs for lumbar laminectomy were 20% greater for Friday cases than for Monday cases, and 24% greater for late-week cases than for early-week cases ultimately transferred to SNFs or rehabilitation centers. A Poisson generalized linear model fit the data best and showed that the comorbidity burden, surgery at a tertiary care center versus a community hospital, and the incidence of any postoperative complication were associated with significantly longer hospital stays. Discharge to home healthcare, SNFs, or rehabilitation centers, and late-week surgery were significant nonclinical predictors of LOS prolongation, even after adjusting for underlying patient health risks and insurance, with LOSs that were, for instance, 1.55 and 1.61 times longer for patients undergoing their procedure on Thursday and Friday compared to Monday, respectively.

CONCLUSIONS

Late-week surgeries are associated with a prolonged LOS, particularly when discharge is to an SNF or rehabilitation center. These findings point to opportunities to lower costs and improve outcomes associated with elective surgical care. Interventions to optimize surgical scheduling and perioperative care coordination could help reduce prolonged LOSs, lower costs, and, ultimately, give service line management personnel greater flexibility over how to use existing resources as they remain ahead of healthcare reforms.
Patterns of median nerve branching in the cubital fossa: implications for nerve transfers to restore motor function in a paralyzed upper limb
Authors: Bertelli Jayme A. , Patel Neehar , Soldado Francisco , Duarte Elisa Cristiana Winkelmann
Published: April 2021

OBJECTIVE

The purpose of this study was to describe the anatomy of donor and recipient median nerve motor branches for nerve transfer surgery within the cubital fossa.

METHODS

Bilateral upper limbs of 10 fresh cadavers were dissected after dyed latex was injected into the axillary artery.

RESULTS

In the cubital fossa, the first branch was always the proximal branch of the pronator teres (PPT), whereas the last one was the anterior interosseous nerve (AIN) and the distal motor branch of the flexor digitorum superficialis (DFDS) on a consistent basis. The PT muscle was also innervated by a distal branch (DPT), which emerged from the anterior side of the median nerve and provided innervation to its deep head. The palmaris longus (PL) motor branch was always the second branch after the PPT, emerging as a single branch together with the flexor carpi radialis (FCR) or the proximal branch of the flexor digitorum superficialis. The FCR motor branch was prone to variations. It originated proximally with the PL branch (35%) or distally with the AIN (35%), and less frequently from the DPT. In 40% of dissections, the FDS was innervated by a single branch (i.e., the DFDS) originating close to the AIN. In 60% of cases, a proximal branch originated together with the PL or FCR. The AIN emerged from the posterior side of the median nerve and had a diameter of 2.3 mm, twice that of other branches. When dissections were performed between the PT and FCR muscles at the FDS arcade, we observed the AIN lying lateral and the DFDS medial to the median nerve. After crossing the FDS arcade, the AIN divided into: 1) a lateral branch to the flexor pollicis longus (FPL), which bifurcated to reach the anterior and posterior surfaces of the FPL; 2) a medial branch, which bifurcated to reach the flexor digitorum profundus (FDP); and 3) a long middle branch to the pronator quadratus. The average numbers of myelinated fibers within each median nerve branch were as follows (values expressed as the mean ± SD): PPT 646 ± 249; DPT 599 ± 150; PL 259 ± 105; FCR 541 ± 199; proximal FDS 435 ± 158; DFDS 376 ± 150; FPL 480 ± 309; first branch to the FDP 397 ± 12; and second branch to the FDP 369 ± 33.

CONCLUSIONS

The median nerve's branching pattern in the cubital fossa is predictable. The most important variation involves the FCR motor branch. These anatomical findings aid during nerve transfer surgery to restore function when paralysis results from injury to the radial or median nerves, brachial plexus, or spinal cord.

Published: April 2021

When designing the antenna field of a stationary HF transmitting radiocenter, it is necessary to provide for reserving ground-based symmetrical antennas operating on round-the-clock radio directions with backup, fast-deployable antenna systems. As such antennas, it is proposed to use asymmetric vertical dipoles, active phased antenna arrays (APAA) based on them with a controlled directional pattern. This article considers methods for calculating such systems, a method is developed for determining the phase relationships of currents at the inputs of APAR elements, taking into account its placement and functioning on a real object. The results of route tests of single antennas and APAA on a radio link with a length of 650 km are presented.
Editorial note
Authors:   University of Zimbabwe, Zimbabwe, Magosvongwe Ruby
Published: April 2021

We argue in the present article that cumulatively over time, inexorable as it is, like change with the evolvement of time, perceptions and values remain immutable to the demands of the day in any society, wittingly or unwittingly. The hearty professor of Political Science from the University of Zimbabwe and former Cabinet Minister in the late former President R G Mugabe’s reign, Professor Jonathan Moyo once remarked: ‘Only a fool does not change his mind’. Does anyone who does change their minds/perspectives answer to the call of wisdom or they actually buttress the foolishness therein ingrained in their life’s outlook/worldview, generally? What is there to gain or lose by adjusting perceptions, positions, persuasions, and strategies to be an active agent in the pursuit of life in its fullness? Is it a crime to shift perceptions in whatever area of one’s life? Is joy always the outcome? In any case, on what authority can one conclusively argue that life is only about the pursuit of happiness, for everyone?

Authors: Kumar N. , Rocha F.G. , Moustafa A.S.Z. , Masten M. , Bruder A. , Parmar K. , Adekola H. , Sampath V. , Monga R.
Published: April 2021

BACKGROUND:

Pregnant mothers with opioid dependency commonly receive maintenance treatment of opioid (OMT), either as buprenorphine (BMT) or methadone maintenance treatment (MMT). We investigated, whether OMT adversely affects standardized neonatal anthropometric outcomes and whether BMT is potentially safer than MMT in this regard.

METHODS:

Retrospective chart review of mother infant dyad, with and without OMT. Infant’s absolute and standardized ( z-score) anthropometric outcomes at birth were first compared, between OMT and control group (negative meconium drug screen), and then between BMT and MMT group. These outcomes were also compared between infants who did or did not require treatment after birth for neonatal abstinence syndrome (NAS).

RESULT:

A total of 1479 participants with MDS were included [Control = 1251; OMT = 228 (MMT = 181; BMT = 47)]. Both the z-scores of birth weight (BW) and head circumference (HC) was lower in OMT group ( p < 0.001). Among the OMT group, GA at delivery was slightly higher in the BMT group ( p = 0.05). There was an inverse correlation between maternal dose at the time of delivery and anthropometric z-scores in the BMT group, mainly in female infants (BW: p = 0.006; HC: p = 0.003). Furthermore, In BMT group, infants with lower HC were more likely to require treatment for NAS ( p = 0.01).

CONCLUSION:

HC and BW when comparing Z-scores were not different between MMT and BMT. High maternal dosing of buprenorphine is associated with lower BW and HC Z-scores but dose effect is not seen with methadone. In addition, there seems to be an association between NAS severity and HC, especially in the BMT group.

To date, there has been limited work evaluating the total cumulative effective radiation dose received by infants in the neonatal intensive care unit. Most previous publications report that the total radiation dose received falls within the safe limits but does not include all types of ionizing radiation studies typically performed on this vulnerable patient population. We aimed to provide an estimate of the cumulative effective ionizing radiation dose (cED) in microSieverts ( μSv) received by premature infants ≤32 weeks from diagnostic studies performed throughout their NICU stay, and predictors of exposures.

METHODS:

Retrospective chart review from 2004–2011. Data included demographics, gestational age (GA), birth weight (BW), length of stay (LOS), clinical diagnosis, and radiological studies.

RESULTS:

1045 charts were reviewed. Median GA = 30.0 weeks (SD 2.7, range 22.0–32.6). Median BW = 1340.0 grams (SD 445.4, range 420–2470). Median number of radiographic studies = 9 (SD 28.5, range 0–210). Median cED = 162 μSv (range 0–9248). The cED was positively associated with LOS ( p < 0.001) and inversely correlated with GA ( p < 0.001) and BW ( p < 0.001). Infants with intestinal perforation had the highest median cED 1661 μSv compared to 162 μSv for others ( p < 0.001).

CONCLUSION:

Our results provide an estimate of the cumulative effective radiation dose received by premature infants in a level 4 neonatal intensive care unit from all radiological studies involving ionizing radiation and identifies risk factors and predictors of such exposure. Radiation exposure in NICU is highest among the most premature and among infants who suffer from intestinal perforation.
Import substitution contribution to Russia’s economic growth
Authors: Gotovsky A. V.
Published: April 2021

Import substitution becomes a hot topic in Russia every time world oil prices fall and the exchange rate of the ruble weakens. Since 2014, it has become a key area of state economic policy. Despite this, various indicators for assessing this phenomenon in the Russian economy have different trends and do not allow to make a clear conclusion about the results achieved. There is also no comprehensive assessment of the impact on economic growth. The paper analyzes approaches to the construction of relevant indicators, taking into account the model tools of the inter-industry balance, offers a macroeconomic method for decomposing GDP growth in the areas of its final use, with the allocation of the contribution of import substitution by increasing the availability of finished domestic products, and localization of production, domestic import substitution, and export-oriented one. Based on the results of calculating the corresponding indicators for 1996—2019, the conclusion is made about the significance of this factor for the dynamics of economic growth in Russia, especially in the periods of high volatility of economic environment. A deliberately high error of forecasts is noted when applying the traditional approach of GDP decomposition from the final demand side, which assumes the preservation in the short term of the proportions of consumption between domestic and imported finished products, materials and components.

The article discusses issues related to the effectiveness of diagnostics of persistent infections. Using PRRS as an example, the relationship between “disease stages” and “diagnostic stages” is discussed on the basis of a meta-analysis of data from diagnostic studies (n = 4307 results) presented in refereed scientific papers to understand the key points. Despite the ongoing improvement of diagnostic methods, none of them individually can be recognized as the only correct decision: the choice of the type of sample and test for research depends on the specific task. In most cases, to establish the true picture of an epizootic, it is necessary to use several research methods and / or types of samples.

Relevance. Modern livestock breeders face an important task of producing organic products, in Russia this is regulated by the Federal Law “On Organic Products” (from 01.01.2020), it allows producers to enter in the state register and mark the products with the “organic” sign. There is a problem of deterioration of the quality of milk, low content of fat, protein, SOMO, deficiency of macro- and microelements, vitamins, which is associated with a violation of the proper feeding of animals. The use of innovative technologies for the activation and modification of silicon-containing minerals (diatomite and zeolite clinoptilolite) enhances their properties. This makes it possible to use them as an adsorbent, an ion exchanger and a source of readily available silicon and other mineral elements to produce high-quality organic products.

Methods. To achieve this goal in the Ulyanovsk region we organized a production experiment in the conditions of a dairy farm of “Agrofirma Tetyushskoe” for a duration of 100 days. Three groups of 50 cows were formed: 1 — control, received only the basic diet (BD), 2 — experimental (BD + supplement based on modified zeolite enriched with amino acids), 3 — experimental (BD + supplement based on modified diatomite enriched with amino acids). The supplement was given once a day in the morning in a mixture with mixed feed, the input rate was 250 g/head/day. For the physiological experiment 5 analog cows were selected in a group. To enrich the minerals a complex of plant-derived amino acids of high purity and biological activity was used.

Results. The intake of additives based on silicon-containing natural minerals (zeolite and diatomite), processed with innovative technologies and enriched with plant-based amino acids, increases the level of animal productivity and ensures the yield of organic products of high-quality. It has a prolonging effect.

Published: April 2021

Relevance. Introduction and variety study of flower and ornamental crops is one of the main tasks of botanical gardens, which aims to expand the promising assortment for domestic floriculture.

Results. In the period from 2018 to 2020 varieties of hybrid iris (Iris x hybrida hort.) from the garden group “tall bearded” were studied in the Stavropol Botanical Garden. The presented 13 varieties belong to foreign selection. Basically, the varieties are characterized by medium or early flowering periods with an average duration of 11-15 days. In the course of the study, biometric characteristics, the economic and biological properties of the varieties were analyzed. The varieties with the longest duration and productivity of flowering were identified. The ability to bear fruit, which is important for further breeding work, was noted in three varieties: Autumn Circus, Pallida Variegata, Immortality. The main disease that harms the studied culture is heterosporiosis. The most resistant to diseases are the varieties Afternoon In Rio, Bye Bye Blues, Pallida Variegata (up to 10% damage). The detected pests (flea beetle, aphid, mole cricket, etc.) generally cause minor damage to the studied plants. In the assessment of decorativeness, 11 parameters were analyzed using a 100-point scale and taking into account the conversion factor. The color, size, shape of the flower, aroma, inflorescence, duration and abundance of flowering, resistance to adverse weather conditions, decorative vegetative part of plants, originality, condition of plants were taken into account. As a result of the variety study, 9 highly decorative varieties were identified: Bye Bye Blues, Stardock, Autumn Circus, Lotus Land, Power Point, Good Day Oregon, Lorilee, Conjuration, Afternoon In Rio.

The current paper has presented the estimating results of the effect of vegetation conditions on a leaf area index, preservation of chlorophyll pigment and productivity of the winter common wheat samples developed by the ARC “Donskoy”. The study was conducted in the laboratory of plant physiology in 2017-2020. There has been used the following methodology: the leaf areas were determined by the Nichiporovich's method (1955), the leaf area index during the periods of ear formation and flowering was estimated according to S.A. Tarasenko (2015). The chlorophyll content in the leaves of winter wheat varieties was assessed by the Shmatko's method (1976). The study results have identified that the leaf area indices and the chlorophyll content in leaves during the vegetation period changed according to the drought resistance degree of plants and depended mainly on the root moisture supply and on the studied genotype. In the conditions of insufficient moisture supply the varieties Krasa Dona, Asket, Etyud and Volny Don formed the maximum values of a leaf area index and preservation of chlorophyll pigment.

Relevance. In peasant-farm conditions and conditions of subsidiary plots, with a wide variety of growing times in greenhouses, which are very different in equipment, heating and use, it is necessary to clarify the agro-ecological terms and introduce regulators of the growth and development of cucumber plants. The use of the adaptogen increases the yield. The aim of the research was to consider the economic efficiency from the use of the adaptogen “Epin-extra” on the growth, development and productivity of various varieties of cucumbers when grown in spring-summer film greenhouses of the Megino-Kangalassky ulus of the Republic of Sakha (Yakutia). Research methods were used according to the methods of the State Commission for Testing and Protection of Breeding Achievements of the Russian Federation [7, 8, 9]. The calculation of economic efficiency was carried out on the basis of the financial costs included in the technological map and the actual costs per 1 hectare according to the method of S.V. Melnikov.

Results. As a result of the research it was found that with a two-fold treatment with a solution of Epin-extra, the development of the main phenological phase of flowering is accelerated for 6 days from control (without treatment with an adaptogen). At the same time, the prevalence of such diseases as ascochito decreases to 1.7%, and the prevalence of root rot is 2.5-3.2 times lower with 2-fold processing, depending on the hybrids. The use of the Epin-extra adaptogen solution increases the quality of products -marketability and weight of cucumber fruits. Due to the use in small volumes, ease of use, the Epin-extra solution increases profitability up to 58.1% with double processing on the Stella F1 hybrid and up to 46.4% in the Maisky F1 hybrid.

Recently, an important element in improving the genetic traits of dairy cattle on commercial farms is the use of interbreeding (crossbreeding). The use of crossbreeding makes it possible to use a variety of additive genetic levels between breeds to grow individuals with higher economic potential. The aim of this study was to analyze the development of udder parameters in crossbred first-borns compared to purebred counterparts and to study the indicators of milk production during milking. The research was conducted on the first-born Ukrainian black-spotted dairy breed and first-generation crossbreeds obtained by crossing with the Brown Swiss breed and on the Ukrainian red-spotted dairy breed and first-generation crossbreeds obtained by crossing Ukrainian red-spotted dairy breed with Montbeliarde breed. Two groups of purebred and local first-borns were formed in both farms. Both farms use the same type of year-round feeding of cows with complete feed mixtures. The study was performed on first-born cows during weaning (2–3 months of lactation). It was found that local first-borns obtained by crossing red-spotted and Montbeliarde breeds outnumbered purebred red-spotted analogues in terms of measurements and udder indices. The opposite situation was observed in local first-borns obtained as result of crossing black-spotted and Brown Swiss breeds, which were inferior in these characteristics to purebred black-spotted analogues. In purebred black and red-spotted cows, the rates of single and daily milking were higher than in local ones. Also, purebred first-borns had a longer duration of single milking, indicators of average and maximum intensity of milk production and milk yield in the first 3 minutes. Prospects for further research are to study the productivity for completed lactation, the quality of milk and the duration of the service period.
