Published: December 2021

Abstract
Investigation and modeling of osmotic dehydration parameters on antioxidative activity of peach samples in combined dehydration methods of osmotic dehydration and lyophilization are done to produce the final product of preserved and enhanced antioxidative activity. Antioxidative activity of dehydrated peach samples was investigated by measuring DPPH radical scavenging capacity, and response surface methodology for developing mathematical models was applied. The results showed that combined osmodehydration and lyophilization processes have led to the increased antioxidative activity of dehydrated peaches samples. All three investigated osmodehydration process parameters affected the increase of DPPH values, where process time was found to be the most influential parameter. Maximal obtained DPPH value of 18.25% was achieved in osmotic dehydration process of 5 hours, in 80% concentration molasses, at a temperature of 50 °C and successive 5-hour lyophilization process. Developed mathematical model of DPPH response of dehydrated peach samples was statistically significant, while predicted and observed responses had good correlation, allowing good prediction of the peach samples’ antioxidative activity.

Authors: Trishkaneva M , Posokina N 
Published: December 2021

Abstract
Agricultural waste and food and processing industry waste are sources of food and biologically active substances with high nutritive value. In this regard, the development of technologies for the processing of waste and secondary raw materials can be considered as one of the promising areas for the development of alternative technologies in the production of new types of food products, which will allow for more effective development of complex deep processing of raw materials. One of the most valuable types of secondary raw materials is the waste of vegetable raw materials obtained as a result of technological processes of processing fruits and vegetables in the production of canned products. At the same time, today a rather low efficiency of waste processing is observed, which in the CIS countries on average accounts for about 45% of production and consumption waste, including in the food processing industry. For comparison, in European countries, the share of waste involved in re-production is 80–87%. In these conditions, the search for technological methods and solutions that allow the most complete use of the full potential of plant raw materials remains relevant. The article presents the results of the analysis of patent documentation for innovative developments in the use of waste generated during the production of canned products to obtain new types of functional food products.

Published: December 2021

Abstract
It has been established that the products of processing of poultry slaughter products within the species groups can be additionally divided according to the principle of the meat part content. The meat part of the products may consist of meat and products of processing of poultry and agricultural animals slaughter products. The analysis of the possible composition of the non-meat part of the product is presented. The criterion for assigning products to a homogeneous group with a high content of the meat part – “poultry meat products” has been determined. The value of the criterion has been determined. The analysis of the protein content in model formulations of focal types of products with the established value of the criterion for assignment to a homogeneous group was carried out.

Abstract
The article discusses the impact of severe drought on the growth and development of winter wheat plants. The studies were carried out in 2018-2020. As a starting material, we used 57 samples of winter soft wheat bred by ARC “Donskoy”. The studies were carried out under laboratory and vegetation methods. According to the analysis, it was revealed that the highest values of the index of complex resistance were shown by the samples: intensive type - 1630/17 (282.8 rel.units), 2078/16 (265.1 rel.units), 1990/17 (265, 0 rel.units); semi-intensive type -1727/17 (260.6 rel. units), 2243/17 (258.6 rel. units), 522/16 (252.8 rel. units). The maximum value of the degree of drought resistance of samples of the intensive type was noted for lines 2243/17 (92.4%), 1727/17 (84.9%), and 522/16 (82.6%). Among 36 samples of winter soft wheat of intensive type, high drought resistance was noted in 67% (24 samples) with germination from 71.6 (Univer) to 92.9% (1630/17). High values of heat resistance (I-81-100% of germination) out of 57 studied samples of winter wheat were noted in 56 genotypes, the indicators of which ranged from 85.1% (1181/16) to 98% (Zodiac, 1166/15, 1275/16). The highest grain yield under model drought conditions was noted for winter wheat varieties Zodiac (332.86 g/m2), Premiera (332.48 g/m2) and Podarok Krymu (317.50 g/m2), which is higher than the yield of the Ascet classifier (292.97 g/m2) by 8.0-13.7%..

Of the 130 studied samples of the collection of peas, which had at least 25.0% of the protein content in the grain, on average over the years of research, only 13 samples had a protein content of at least 25.0%. The highest minimum protein content was observed in the Russian-bred OMK-3 sample, which had an indicator of 26.1%. For the rest, the minimum value was from 25.0 to 25.3%. The maximum protein content over the years of research in pea samples was from 25.8 to 29.7%, of which samples 193/73 (Ukraine) (29.7%), OMK-3 (Russia) (29.5%), NS-01-68 (Bulgaria) (29.1%), B-887 (Russia) (28.7%) and Orel-330 (Russia) (28.7%). The average value of the coefficient of variation for varieties, characterizing intravarietal variability, was 6.8% on average for the collection, with the lowest value being 1.2% and the highest value being 15.9%. In the 13 isolated samples, the intravarietal variability was lower than the average for the collection as a whole (1.2-6.6%), except for sample 193/73 (Russia), for which it was 7.3%. This sample has the highest average and maximum protein content in the years of research. The selected 13 samples from the pea collection are of breeding value as initial parental forms in the direction of increasing the protein content in the pea grain and enhancing the stability of this indicator.

Authors: Ivanov Yury , Novikov Nicolai 
Published: December 2021

Abstract
The problem of livestock premises air environment parameters ensuring in terms of temperature, humidity and CO2 gas content, established by zoo technical standards, is considered. The problem is formulated as a problem with non-linearity object and consists in its phase (temperature, humidity and CO2 gas content) coordinates stabilizing by the premises heating capacity and its air exchange intensity controlling. A mathematical model of control object’s dynamics parameters based on material flows and energy balance equations is developed. A cyclic algorithm for this problem solving has been developed, it consists of two successive stages: the control search this problem solving, and the found control establishment until any of the coordinates’ phase go beyond the established limits due to disturbances.The search for the control vector consists in periodic relay switching of its coordinates from specified maximum to minimum values so that the phase coordinates remain in the region of permissible variation. It is shown that the control vector corresponding coordinates as their average values for the switching cycle are defined. A block diagram of the control system implementing the developed algorithm is presented. The calculation data are given for a pigsty for 1300 animals.

Authors: Lachuga Yury , Pakhomov Victor , Braginets Sergey , Bakhchevnikov Oleg , Rudoy Dmitry , Maltseva Tatyana 
Published: December 2021

Abstract
The object of the study was an extruded feed made from an undivided grain heap of winter wheat, stripped in the phase of waxy ripeness. The use of this type of inexpensive raw material makes it possible to increase the protein content in feed by 7-8% in comparison with feed based on fully ripe grain. The process of extruding feed based on waxy ripeness wheat ears is satisfactory. It has been established that extruded feed based on a grain heap can be successfully used for feeding farm animals. To use extruded feed from wheat ears harvested in the phase of waxy ripeness, the addition of raw materials of animal origin in an amount of no more than 20% is required for feeding fish, which is less than for feed based on full ripeness wheat grain.

Published: December 2021

Abstract
The development of effective methods of prevention and treatment of hypovitaminosis in piglets is one of the promising areas of veterinary science and practice. The article presents the results of studies obtained when evaluating the effectiveness of the use of complex multivitamin preparations from various manufacturers: Trivit (CJSC Mosagrogen, Russia), Tetrahydrovit (LLC NITA-PHARM, Russia), Dufalite (Zoetis Inc, USA). The peculiarity of vitamin nutrition of pigs is associated with the absence or insufficient synthesis of water-soluble B vitamins in their body, so they should always be present in the diet feed. In addition, pigs are in urgent need of the delivery of carotene, vitamin A, C, E, D with food, which is due to the intensity of metabolism and energy in the body; at the same time, the consumption of vitamin A and carotene increases exponentially. Based on the conducted studies, it was found that the most effective method of prevention and treatment of hypovitaminosis in suckling piglets is the use of the multivitamin drug Tetrahydrovit intramuscularly on the 1st day of life and again after 7 days at a dose of 1 ml per head 1 time per day.

Published: December 2021

Abstract
The skin performs the most important physiological functions of the body. The protective function is the main among them. This article presents the results of studies of how the technological stress affects the protective properties of pig skin depending on the animals’ age. The parameters of the skin, characterizing the epidermis, the main protective skin barrier, were studied in domestic Poltava Meat Breed pigs of different ages. The skin epidermis in animals of all studied age groups is actively involved in the performance of protective functions. Upon reaching the live weight of 100 kg, the young boars of the breed experience a great technological load, which causes tension in the skin protective systems and, thus, activation of these systems. This results in greater values of the epidermis thickness comparing to adult boars (by 17.22% (p⩽0.05)) due to an increase in its inner (underlying) layers (by 33.05% (p⩽0.001)). The stratum corneum of the young boars’ epidermis is thinner but more dense, with pronounced sudanophilia. With pigs reaching their adulthood, the tension in their protective factors decreases and stabilizes. In adult boars, the stratum corneum is thicker (a significant difference is 6.82 μm or 28.14%), but it is more susceptible to keratinization, is looser and has pronounced fibrillation. These changes probably mark the already developed adaptation to the existing natural and technological conditions.

Published: December 2021

Abstract
Experimental studies of the impact of agricultural mobile machinery movers on the soil are seasonal in nature and require complex experimental equipment. The complexity of the physical processes occurring in the elastic wheel-ground system requires the introduction of many assumptions and limitations that reduce the accuracy of the results, according to the design of simulation models performed in the software environment. The aim of the research was to study the influence of the design parameters of the tire on the efficiency of the normal deflection along the contact spot zone X. Studies have shown that 65% to 77% of the normal deflection of the tire is used when passing the contact spot. The reinforcement parameters of the tire frame have the greatest impact on the efficiency of the normal deflection along the contact spot zone. With an increase in the number of layers of the frame cord from 2 to 8, the coefficient of usability of the normal deviation for the stroke of the contact spot decreases from 0.761 to 0.689, with an increase in the angle of inclination of the frame cords - decreases from 0.755 to 0.693.

Published: December 2021

Abstract
The article deals with water management complexes, including hydraulic structures and reservoirs. The purpose of the study is to identify the attractiveness, significance and potential of such complexes as objects of recreational and ecological tourism. The analysis of unique hydrotechnical objects of different countries of the world is carried out. The features of their designs and ways to increase the attractiveness of objects for tourists are shown. The simplest and most common method of increasing the recreational potential of a water management facility is the arrangement of species sites. It is much less common to arrange organized recreation areas for participants of the natural tourism route using hydraulic structures or separate entertainment attractions for tourists. Significantly more complex complexes with the inclusion of high-and medium-pressure dams are typical for recreational park areas. A separate group includes objects that serve as historical and educational sites or monuments of history, culture and technology. Thus, the analysis revealed a wide variety of uses of hydrotechnical objects as attractive places for recreation and eco-tourism. The conclusion is made about the expediency of the development of the considered areas of use of water management complexes.

Published: December 2021

Abstract
We studied the methane content in Lake Onego bottom sediments and bottom water and revealed a wide variation of its concentrations among different parts of the lake. Methane concentrations were the highest in the pockmarked area of Petrozavodsk Bay, where hydrocarbon gases rise to the lake bed surface from the depth. Methane emissions from Lake Onego sediments were estimated. We show that in addition to the geological and geomorphological characteristics of the basin, the flux rate depends on how the lake sediments are forming under the uneven human pressure and climate oscillations of today.

Abstract
The analyze of dynamic of quantity and composition of the Russian catches in the Sea of Azov, Black and Caspian Seas in the 21st century was made. It has been shown that catches decrease with a simultaneous increase in the proportion of marine fish proper. The analyze of aquaculture development in southern regions is provided and also identified the prospects for its development in the near future. Currently, there is a positive dynamics of growth in the production of commercial fish farming products. Since 2000 this parameter has decreased from 77 to 328 thousand tons in 2020. The volume of aquaculture in the southern regions of the country in 2020 amounted to more than 78 thousand tons, which is 24% of the total Russian. In Rostov and Astrakhan region, Krasnodar territory obtained 90.6% aquaculture production. The perspective ways are pasture aquaculture, ponds and industrial fish farming, recreational aquaculture, mariculture. The expansion of the species diversity of farmed fish is possible both due to the aboriginal ichthyofauna and the use of previously acclimatized species.
