Context. Millimeter astronomy provides valuable information on the birthplaces of planetary systems. In order to compare theoretical models with observations, the dust component has to be carefully calculated.

Aims. Here, we aim to study the effects of dust entrainment in photoevaporative winds, and the ejection and drag of dust due to the effects caused by radiation from the central star.

Methods. We improved and extended the existing implementation of a two-population dust and pebble description in the global Bern/Heidelberg planet formation and evolution model. Modern prescriptions for photoevaporative winds were used and we accounted for settling and advection of dust when calculating entrainment rates. In order to prepare for future population studies with varying conditions, we explored a wide range of disk, photoevaporation, and dust parameters.

Results. If dust can grow to pebble sizes, that is, if they are resistant to fragmentation or turbulence is weak, drift dominates and the entrained mass is small but larger than under the assumption of no vertical advection of grains with the gas flow. For the case of fragile dust shattering at velocities of 1m s−1 – as indicated in laboratory experiments –, an order of magnitude more dust is entrained, which becomes the main dust removal process. Radiation pressure effects disperse massive, dusty disks on timescales of a few hundred Myr.

Conclusions. These results highlight the importance of dust entrainment in winds as a solid-mass removal process. Furthermore, this model extension lays the foundations for future statistical studies of the formation of planets in their birth environment.
AGN jets do not prevent the suppression of conduction by the heat buoyancy instability in simulated galaxy clusters
Authors: Beckmann Ricarda S. , Dubois Yohan , Pellissier Alisson , Polles Fiorella L. , Olivares Valeria
Published: August 2022

Centres of galaxy clusters must be efficiently reheated to avoid a cooling catastrophe. One potential reheating mechanism is anisotropic thermal conduction, which could transport thermal energy from intermediate radii to the cluster centre. However, if fields are not re-randomised, anisotropic thermal conduction drives the heat buoyancy instability (HBI) which re-orients magnetic field lines and shuts off radial heat fluxes. We revisit the efficiency of thermal conduction under the influence of spin-driven active galactic nuclei (AGN) jets in idealised magneto-hydrodynamical simulations with anisotropic thermal conduction. Despite the black hole spin’s ability to regularly re-orientate the jet so that the jet-induced turbulence is driven in a quasi-isotropic fashion, the HBI remains efficient outside the central 50 kpc of the cluster, where the reservoir of heat is the largest. As a result, conduction plays no significant role in regulating the cooling of the intracluster medium if central AGN are the sole source of turbulence. Whistler-wave-driven saturation of thermal conduction reduces the magnitude of the HBI, but does not prevent it.

Published: August 2022

The article presents the results on evaluating the effect of the gamma-octalactone compound isolated from Eucalyptus viminalis leaf extract on the amino acid and fatty acid composition of protein and lipids of broiler chickens' muscle tissue. The object of the study was 7-day-old broiler chickens of the Arbor Acres cross. During the experiment, the control group poultry consumed the main diet (MD); the poultry of the experimental groups received the main diet plus gamma-octalactone at the following dose: group I – 0.05 ml/kg l.w./ day; II – 0.1 ml/kg l.w./ day; III – 0.2 ml/ kg l.w./day. It was found that the experimental compound's introduction into the diets significantly increases protein and fat content, as well as improves the balance of experimental groups' chicken meat for essential amino acids, as evidenced by a significant increase in the content of leucine and isoleucine - 2.27% (P≤0.01), valine - 0.8% (P≤0.05), phenylalanine 0.44 (P≤0.05) % in chickens of the experimental group III in relation to the control. With a relatively stable amount of saturated fatty acids in the experimental groups, compensation for insufficient synthesis of polyunsaturated fatty acids was observed by increased accumulation of monounsaturated fatty acids. However, despite the existing differences in the concentration of unsaturated fatty acids, no significant intergroup changes were observed.

The article presents the study results on the effect of probiotic (Bacillus cereus IP 5832) and coumarin on the chemical and amino acid composition of body tissues when fed to broiler chickens together with the main diet. According to the experimental results, an increase in the concentration of dry matter by 0.27% and crude fat by 0.75% was found in the liver of young animals from the I experimental group compared to the control. At the end of the experiment, the broilers from the control group were inferior in the protein amount in the liver of the experimental poultry by 0.46%, 2.69 (P ≤0.05) and 1.16%. A similar pattern was observed when studying pectoral muscles' chemical composition on the 16 and 29 day study period; the accumulation of dry matter and protein in the poultry's pectoral muscles from the III experimental group by 0.7 and 0.71%; 0.89 and 1.21% relative to the control was revealed. Feeding broilers with a basic diet plus coumarin contributed to the accumulation of essential amino acids in their liver: lysine – by 1.05%, phenylalanine – by 0.41% and leucine-isoleucine by 0.63% relative to the control.

Published: August 2022

In this experimental work, the effect of vitamin and mineral concentrate P52-1 of domestic production as part of barley and wheat compound feeds on the growth dynamics of young pigs and their health indicators for the experiment duration was studied. At the same time, the physiological parameters of the health of the studied animals were considered. Morphobiochemical studies of blood allowed to conclude that this feed additive had a positive effect on the metabolism of young pigs in the post-weaning period and during rearing. The result of the use of P52-1 was an accelerated increase in the mass of the test animals of the experimental group compared with the control group in terms of average daily and gross increments. At the same time, in the experimental group of animals, morphobiochemical indicators exceeded those of the control group, while they were within the normal range. The cultivation of young pigs using a multienzymatic premix, of domestic production, provides an average daily increase in animals of the experimental group of over 16%.

Authors: Zaitsev Sergei Yu. , Voronina Oksana A.
Published: August 2022

The main aims of research were: to measure the surface tension (ST) values of hybrid pig blood; to establish the relationships between these ST-values and obtained biochemical parameters of the same blood samples. All studied animals (n=43) were healthy and grown at the feeding stations (Russia). The ST-values (measured using PAT-device) of the pig blood were obtained at initial (n=30) and final (n=13) points of animal fattening. The following correlations between eST at final (or initial) point of pig fattening and the biochemical parameters were obtained: +0.80 (+0.19) with the ratio of albumins to globulins (A/G), -0.39 with globulins (-0.38) with phospholipids, +0.32 (+0.40) with the “de Ritis” coefficient, -0.52 (+0.35) with Cl. The correlations between eTA at same fattening points and the biochemical parameters were obtained: +0.32 with A/G ratio, +0.18 with globulins, +0.36 with phospholipids, +0.28 (+0.17) with the “de Ritis” coefficient, -0.32 (+0.21) with Mg, +0.35 with Fe, +0.30 with Cl, +0.31 (+0.34) with the ratio of calcium to phosphorus (Ca/P). Such tendency indicated the stabilization of pig physiological-biochemical status during their fattening. The authors recommended the following eST (42-46 mN/m) and eTA (10-30 mN·m-1·s-½) blood parameters as reference values for further applications in husbandry.

The study of roach for the metazoic parasites' presence allowed to detect D. crucifer, D. chromatophorum. P. homoion homoion, C. laticeps, O. felineus, P. ovatus, R. campanula, I. platycephalus, S. bramae, P. elongatum. R. acus (l.) Unionidae gen. sp E. sieboldi P. geometra Proteocephalus sp. The greatest species diversity was observed in fish in groups 2+, 3+, and 4+ (11, 14, and 13 species of parasites, respectively). At the ages of 1+ and 5+, 8 species of parasitic organisms were found, in the group of 0+ - 6 species of parasites. The greatest parasites' species diversity was noted on the gills - 5 species, in the intestines – 3 species, in the muscles and mesentery - 2 species, in the lens, on the fins, in the kidneys and on the body surface - 1 each. Cluster analysis on the invasion extent of roach parasites aged 0+ - 8+ showed groups 1+ - 4+ merging into one cluster; fish aged 0+, 5+ and 6+-8+ are allocated to a separate cluster. The calculated clustering by IE in age groups shows the similarity of parasite fauna and the magnitude of the invasion extensiveness at the ages from 1+ and 4+, and 6+ - 8+. With age, the biotopic distribution and nutrition spectrum of roach changes, which affects its infestation by parasites and the composition of the parasitic community as a whole.
Mycoplasmosis of farm animals

Published: August 2022

The article presents an overview characterizing the spread of Mycoplasma infections among various kinds of farm animals. It also demonstrates the urgency of the pathogen of the disease - Mycoplasma spp., its characteristics and structural features, which provide significant differences from other types of microorganisms. Most species of Mycoplasma spp. are strictly specific to the host, but some of them pose a danger to humans. Mycoplasmas in animals cause diseases ranging from acute forms of the disease to an asymptomatic course. With the development of pathology, damage to various organs and tissues is observed, which indicates a high tropism of the pathogen, which contributes to the development of a generalized form of pathology. The most susceptible is the respiratory and reproductive tract, as a result of which farms are inflicted with significant economic damage. At the same time, some of the mycoplasmas build a symbiotic relationship with the host organism. Attempts to use antimicrobial therapy, including in various combinations, do not always lead to a positive result, which is due to the development of antibiotic resistance of the pathogen. Thanks to the change in the genome, mycoplasmas have become the smallest bacteria capable of self-replication. Mycoplasmas are classified as parasites or symbionts of animals, insects and plants, while the disease itself is opportunistic. Diagnosis of the disease consists mainly of three methods: serological, molecular biological and bacteriological, which are often used simultaneously. The cultivation of mycoplasmas has its own characteristic difficulties and features due to the structure of bacteria.
Variability of indicators of milk productivity in cows of different genotypes and with different index of lactation constancy
Authors: Bakai F.R. , Mukhtarov A.M.
Published: August 2022

at present, the livestock industry in Russia is aimed at obtaining highly productive cows, taking into account their individual characteristics. It is known that animals with high genetic potential react to certain environmental changes especially. Hence, phenotypic evaluation will not help select the best cows with high genetic potential. Therefore, the assessment of individual qualities requires a new approach, which can be safely attributed to various kinds of indices, among which the index of lactation constancy occupies a special place. Such an index score fully characterizes the genotype. Any herd is characterized by a large genetic diversity of individuals. The variability of milk productivity traits determines this diversity, therefore, among highly productive cows there are those that are able to maintain the amount of milk yield and other valuable traits and be able to pass them on to their descendants. The main goal of breeding is aimed at identifying cows with such a valuable genotype and further their widespread use within the farm. Cows, daughters of different breeding bulls with a high index of lactation constancy, can serve as a starting point in the selection of producers with further recommendation for their use in different populations with different levels of productivity.

The purpose of this work was to realize the reproductive qualities of sows and the productivity of young pigs with immunotropic preparations PigStim-C and PigStim-M. To set up the experiment, 30 heads of nursing sows were selected on the 15th day after the first farrowing. The selected sows were divided into 3 groups according to the breed, reproductive qualities and reproductive health according to the principle of pairs of analogues. It was found that intramuscular injection of the immunotropic drug PigStim-C to animals of the 1st experimental group (and PigStim-M to animals of the 2nd experimental group) at a dose of 5 ml per head on the 15th, 20th, and 25th day after farrowing contributes to: reducing the period from weaning to coming into heat and the onset of the optimal period for insemination by 4.5-9.1%; an increase in the success of insemination from 90% in the control group to 100%; an improvement in sows’ prolificacy by 8.1-8.6% and a decrease in the number of stillborn piglets by 16.7-33.3%; a decrease in the number of sows with prolonged farrowing by 2-3 times resulting in a decrease in the occurrence of postpartum pathologies of reproductive organs, such as metritis-mastitis-agalactia syndrome, as well as an increase in the therapeutic measures' efficiency in case of their occurence; a decrease in the disease incidence of young pigs obtained from these sows during the next farrowing by 36.8-41.5%, an increase in their viability by 1.45-2.97% and an increase in live weight at the end of the growing period by 0.16-0.18 kg, rearing – by 1.1-1.22 kg, and when removed from fattening – by 3.6-4.0 kg.

Published: August 2022

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.

Water is an extremely important element of metabolism in the body of pigs during ontogenesis. It acts as a transport and solvent medium for nutrients and waste products; improves the digestive system; provides a normal balance of electrolytes and mobility of joints; regulates body temperature; serves as a conductor of biochemical reactions. Pigs' need for water depends on many factors, including feed type, ambient temperature, and general health. Observations of the water consumption of pregnant sows indicate that the ratio of water and feed is stable in sows of the first and second farrowing, and water consumption increases further with each farrowing. The lactating animal should consume up to 40 liters of water per day. In weaning pigs and pigs for fattening, the maximum consumption is noted at the beginning and at the end of the period. Ethological observations have found that animals imitate each other when drinking, showing a herd reflex. With population increase in the group, water consumption increases. The dynamics of the process is influenced by feed type and feeding method. Lack of water leads to dehydration, which affects the behavior of pigs.

Diseases in newborn animals cause significant damage to animal husbandry. This is a complex problem, in which, along with such factors as the environment and the pathogen, an important role is played by the reaction of the body of newborns and their close connection with the mother's body. The study of enzyme relationships in the functional system «mother-fetus-newborn» can make a significant contribution to solving the problem of improving the safety of the population of newborn animals. Newborn animals have different degrees of functional maturity. Functional capacity of some organs and the system of the newborn, in comparison with the parent individuals, can be determined both genetically and by the conditions of intrauterine development. Currently, a sufficient number of facts have been accumulated that any deviations or violations of homeostasis parameters the mother's body affects the fetus and Vice versa. The main role in compensating for impaired functions belongs to the mother's body, but the fetus is also able to participate in these reactions to a certain extent. Functional integration of fetal and maternal homologous systems when performing homeostatic functions concerns the activity of the blood enzyme component. The aim of our research was to study quantitative and qualitative changes in the activity of blood enzymes in non-pregnant sows, in the first and second half of pregnancy and the postpartum period.

Our study presents the results of a comparative assessment of meat productivity and biological value of meat in bulls of various breeds. The work was carried out at OJSC named after N.E. Tokarlikov of the Almetyevsk region of the Republic of Tatarstan using industrial technology in three groups (18 heads in each group): I - Simmental, II - Black-and-White and III - Hereford. Relatively high rates of meat productivity and qualitative characteristics of the meat were determined in Hereford bulls: meat weight was 1.7 and 4.5% more compared with Simmental and Black-and-White peers. The meat index in animals of the meat direction (4.59) is higher by 7.5 and 5.5% compared to analogues of I and II groups. The specific gravity of the protein did not have significant differences (18.60-19.05%). At the same time, a higher level of fat was noted in meat from beef cattle - by 1.05 and 1.51%. They also favorably differed in essential amino acids content in the proteins of muscle tissue. Their amino acid score was above 100%. A more balanced ratio of essential amino acids was established in individuals of beef cattle when calculating the biological value of the protein. Meat from animals of Hereford breed was differed by relatively high level of non-essential amino acids - 318.8 mg per 1 g of protein, which is 1.3 and 10.4% more than in the peers of the first two groups.

The article shows for the first time the results of studies on the aftereffect of 4 years of a single use of dairy industry waste - cake as a fertilizer for crops in the crop rotation link: potatoes - spring wheat - potatoes - barley on productivity and product quality. In the spring of 2017, the experimental plot after harvesting the remains of perennial grasses was mechanically processed with a motor cultivator and divided into plots of 10 m2 with the following experimental options: 1. Control (without fertilizers); 2. Complex mineral fertilizer - azophoska with the content of plant nutrients N - 16%, P2O5 - 16%, K2O - 16% at the rate of 100 kg/ha; 3. Cake 3 kg/m2 (30 t/ha); 4. Cake 6 kg/m2 (60 t/ha); 5. Cake 9 kg a.i./m2 (90 t/ha). Variants of experiments were studied in six repetitions. The cake substance gradually mineralizes in the soil and supplies crops with nutrients throughout the growing season. The aftereffect of the cake was studied from 2018 to 2020, and for all the years of research, the maximum yield was observed in the variants with the introduction of cake. So, if in 2020 in the control variant the yield of barley was 2.13 t/ha, then in the variant with azofoska - 2.21 t/ha; in the option of 30 t/ha of cake - 2.41 t/ha; in the option of 60 t/ha of cake - 2.95 t/ha; in the variant 90 t/ha of cake - 3.10 t/ha (HCP05 = 0.22). The agrochemical properties of the soil in the variants with cake application improved significantly: the humus content in the control variant - 3.03%, in the variant with azofoska - 3.16%, in the variant 30 t/ha of cake - 3.22%, in the variant 60 t/ha ha of cake - 3.65%, in the option of 60 t/ha of cake - 3.60%. The content of plant-available forms of phosphorus and potassium in the soil also increased. The pH values of the exchangeable acidity increased to neutral values (6.59).

In the Sverdlovsk region, holstinized black-and-white cattle of the Ural type is bred, which is represented by large, highly productive animals with a high genetic potential for productivity. The purpose of the work is to study the productive qualities of Holsteinized black-and-white cattle with a high proportion of blood relationship in the Holstein breed, depending on the linear affiliation and their relationship. There are no differences in milk yield and milk quality indicators in cows of different lines. All cows were of dairy productivity, as evidenced by the high coefficient of milk production. There was a significant difference between groups of cows of different lines in terms of the lactation stability coefficient, which was higher in the group of cows of the Reflection Sovering line (P≤0.05). The figure clearly shows that the correlation between milk yield and milk quality indicators – FDM and PDM in milk is negative, that is, with an increase in milk yield, there is a decrease in FDM and PDM in milk. A positive correlation has been established between the phenotypic trait (live weight) and their productive qualities – milk yield and lactation stability coefficient, which makes it possible to recommend selection by live weight.

The Ural type of the domestic black-and-white breed is characterized by high productivity and good suitability for use in the conditions of industrial milk technology. During its breeding, the use of purebred bulls-producers of the Holstein breed of both domestic and foreign breeding continues. As a result of the conducted research, it was found that the productivity of cows changes significantly with age. Milk yield for 305 days of lactation increases from 1 lactation to 3 lactation, and then decreases by 369 kg or 3.8% in the fourth, relative to the third, and by 2090 kg or 22.2% in the fifth, relative to the fourth. The productivity of full-aged cows is higher than that of young cows and can remain at a high level for a long period. The quality indicators of milk changed upward from the first to the fifth lactation. High correlation coefficients were established by the conjugation of milk quality indicators with each other, regardless of lactation. They ranged from 0.364 (2 lactation) to 0.533 (1 lactation). That is, a decrease or increase in MJ in milk will lead to the same change in MDB.

Published: August 2022

The Ural type of the domestic black-and-white breed is distinguished by high productivity indicators, good suitability for use in the conditions of industrial milk technology. High productivity is accompanied by a decrease in productive longevity, which raises new questions for livestock workers. The assessment of the productive longevity of cows, depending on belonging to the line, is relevant and has practical significance. As a result of the research, it was found that the highest lifetime milk yield had animals of the Siling Trijun Rokita line, which in this indicator exceeded the rest by 23015 - 30647 kg or by more than 54.0 - 72.0%. In each group there are animals that have low productivity and cows with a high lifetime milk yield of over 65-77 tons of milk. Cows of the Siling Trajun Rokita line have high rates of productive longevity – 5.9 lactation, and the other lines have low from 1.4 to 2.4 lactation. The genetic potential of productive longevity of cows of all lines (with the exception of the Pabs Governer line) is high 9 - 10 lactation. An increase in the duration of lactation does not significantly affect the overall milk productivity of cows.

Published: August 2022

Digital technologies ensure the competitiveness of agriculture and have the ability to attract investment. They are needed to increase milk yield and improve the quality of dairy products. "Smart Farm" is a fully robotic facility that analyzes the feasibility of production. For example, this analysis indicates the economic feasibility of breeding certain breeds of farm animals. Now milking robots are used all over the world. If the average milk productivity of cows is 5,000 liters per year, then due to the introduction of modern technologies, the result can be up to 12,000 liters per year. Another plus is the fact that the production process can take place without the presence of an operator. A smart farm is a fully automated process. Such a farm can independently calculate the economic profitability of its production, where the necessary digital technologies are used. Based on the analysis, a decision is made to optimize the production process.

The article deals with the issues of rational use of the farming system under the conditions of anthropogenic impact. In this regard, a new scientific direction is considered to improve the modern technology of growing crops that contribute to the rational use of the indicator of energy resources by 2-3 times. This approach necessitates a revision of the structure of crop placement depending on the solar radiation coefficient (KR). In the long term, due to the irrational use of energy resources, the degradation of soil potential has intensified, which has dramatically affected the gross yield and the sustainability of agricultural production. Therefore, there is a need to move to a new level of assessment of the basic principles and methods of the farming system. Suggested comparative analysis of two technologies for the cultivation of corn for grain in the Zhambyl region is proposed: the existing and resource-saving. The article was carried out as part of the implementation of applied scientific research in the field of the agro-industrial complex under the scientific and technical program (IRNBR10764920) "Technologies and technical means of irrigation when introducing new irrigated lands, reconstructing and modernizing existing irrigation systems" for 2021-2023.

With the arrival of the coronavirus, life will not return to its usual course. Some industries are under threat of existence. With each new wave of morbidity of the population, most of the business loses its achievements, some stop their entrepreneurial activities, losing resources not only for development, but also for current activities. The advantage of the agro-industrial complex of the country is that it is a producer of basic foodstuffs for the population. Therefore, the pandemic crisis affected the agricultural sector less painfully. However, as the current analysis shows, the agricultural sector of the economy continues to develop with dignity. People will always need protein food, and the agro-industrial complex will provide this need, while becoming less vulnerable. It should be noted that the agricultural sector is characterized by continuity of production.

A better understanding of elastomers’ behavior during Rapid Gas Decompression (RGD) requires advanced knowledge of what is happening during gas sorption and desorption. This will offer to improve numerical simulation phenomena to consider a real environmental use of an O-ring, as for thermal applications. A previous experimental study developed testing protocols to investigate the performance of elastomeric O-rings. The non-contact measurement technique has been validated to identify the swelling and shrinking coefficients during sorption and desorption of carbon dioxide (CO2) from a Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring. The present work describes the effect of CO2 pressures on Fluorocarbon rubber (FKM) seals behavior coupled with temperature. To evaluate the effect of reinforcing the HNBR and FKM matrices with nanofillers, experimental tests were carried out and compared with those of the two elastomers without fillers. The four materials’ CO2 sorption and desorption coefficients are identified, and their swelling upon decompression is measured. It appears that HNBR is the best candidate under the applied service conditions. On the other hand, the nanofillers introduced in the elastomers may cause some early damages under RGD conditions.
An improved PDE-constrained optimization fluid registration for image multi-frame super resolution

Published: August 2022

The main idea of multi-frame super resolution (SR) algorithms is to recover a single high-resolution image from a sequence of low resolution ones of the same object. The success of the SR approaches is often related to a well registration and restoration steps. Therefore, we propose a new approach based on a partial differential equation (PDE)-constrained optimization fluid image registration and we use a fourth order PDE to treat both the registration and restoration steps that guarantee the success of SR algorithms. Since the registration step is usually a variational ill-posed model, a mathematical study is needed to check the existence of the solution to the regularized problem. Thus, we prove the existence and of the well posed fluid image registration and assure also the existence of the used second order PDE in the restoration step. The results show that the proposed method is competitive with the existing methods.
