Abstract

The lipid peroxidation and antioxidant defense system is a balanced system responsible for the processing and utilization of lipids in the body’s cells. It plays an important role in lipid metabolism, cell protection and overall health of the body. Its proper functioning is necessary to ensure optimal functioning of cells and organs throughout the body. The article clinically and experimentally substantiates the pathogenetic role of lipid peroxidation products and the level of antioxidant protection in cows with endometritis and purulent-necrotic processes in the finger area, as well as with the comorbid course of endometritis and orthopedic pathology. It has been shown that multimorbid manifestation is accompanied by a more severe course than individual diseases. It has been established that the development of postpartum endometritis and purulent-necrotic lesions of the limbs in cows is accompanied by a highly significant increase in lipid peroxidation products in the blood serum against the background of a decrease in the amount of antioxidant enzymes, with the exception of ceruloplasmin. Moreover, these changes are accompanied by a sharp jump in the comorbid course of endometritis and orthopedic pathology in highly productive animals.

Abstract

Relevance. The article presents data on the toxicological assessment of the safety of the specific immunobiostimulant of antigen-directed action “Transfer Factor” in a form ready for intramuscular administration and obtained from the blood of hyperimmunized donors on laboratory animals in an acute experiment.

Methods. The object of the study was the finished form of “Transfer Factor”, the acute toxicity of which was determined in models on laboratory animals (nonlinear mice, nonlinear rats).

Results. It was found that after administration of the drug to mice intramuscularly (0.25 ml/head) and intraperitoneally (0.5 ml/head), to rats intramuscularly (2.5 ml/head) and intraperitoneally (2.5 ml/head), muscle tremor is observed, disappearing after 15–20 minutes. Intraperitoneal administration of the drug to mice and rats in dosages of 0.75 ml/head and 3.75 ml/head, respectively, determines the presence of tremor lasting 40 minutes. During the 14-day observation period, the body weight of mice and rats increases by 10.15-14.25 and 11.84-17.67%. Autopsy of animals does not reveal visible changes in the location of organs and fluid in the abdominal and pleural cavities. However, some pathological changes in color, consistency and size are found in the lungs, heart, spleen and liver with intramuscular administration of Transfer Factor to mice and rats at a dose of 0.25 ml/head and 2.5 ml/head, intraperitoneal administration to mice at a dose of 0.5 ml/head and 0.75 ml/head and to rats 2.5 ml/head and 3.75 ml/head. Based on the totality of changes in the vital signs of laboratory animals, body weight and macroscopic characteristics of internal organs according to GOST 12.1.007-76, the drug “Transfer Factor” can be classified as hazard class IV “Low-hazard substances”.

Abstract

The work is devoted to the issues of using polyhydroxy acids in rabbit breeding. Antioxidants are extremely important compounds for living organisms. The authors considered the effect of gluconolactone used in the animal diet on the metabolic processes and physiological indicators of life activity of rabbits. Based on the studies (using gluconolactone as an example), the advisability of including supplements containing polyhydroxy acids in the rabbit diet is shown. Polyhydroxy acids, which are antioxidants, when regularly introduced with feed, help to increase the overall resistance of the body, stimulate the growth and healthy development of animals, which in turn leads to obtaining high-quality agricultural products. Rabbits, like other animals, can obtain antioxidants from plant foods, but their concentration may be insufficient for full protection against oxidative stress. To stabilize feed rations, various biologically active additives are used, which make it possible to increase the efficiency of animal rearing and improve productivity indicators. Thus, polyhydroxy acids, in particular gluconolactone, are well suited for sensitive animals that require the utmost care and gentle rearing.

Abstract

Four diets were developed, including the control (main diet), which actually contained 34.00% crude protein, while the other three contained protein close to this value, taking into account the measurement error, and isoleucine in groups 2, 3 and 4, 4.9%, 8.51% and 12.12%, respectively. The study of the effect of L-isoleucine additives in compound feeds on the growth of tilapia (Oreochromis niloticus) showed that varying the concentration of this amino acid has a significant effect on fish growth rates. Adjusting dosages makes it possible to achieve more efficient use of feed in aquaculture conditions. It was found that when the amino acid isoleucine is introduced into the diet, feed conversion decreases by 0.64 points with an additional concentration of 1.42 g/kg of feed (4.9%), by 0.88 points with additional administration of isoleucine by 1.55 g/kg of feed (8.51%), by 0.76 points with an additional concentration of 1.68 g/kg of feed (12.12%). It was shown that the best group with the lowest feed conversion rate was the 3rd group, in which the amino acid isoleucine was introduced into the diet by 8.51% more than in other groups. The optimal level of isoleucine administration in tilapia feed is 1.55 g/kg of feed (8.51%). It was found that the ash content in the carcass of O. niloticus increased by 0.8%, fat — by 1% in muscles compared with the control.

Abstract

Relevance. As a result of morphological studies, materials were obtained characterizing the effect of genotype and castration of young cattle and the development of the bone system in the postnatal period of ontogenesis.

Methodology. For the purpose of conducting the experiment, groups of experimental young animals were selected:

Results. The influence of the genotype and castration of young cattle on the absolute weight and length of individual parts and the entire skeleton of gobies and castrated gobies of the Bestuzhev breed and its first-generation crossbreeds with simmentals was established. The advantage of crossbred bulls of the ½ Bestuzhevskaya × ½ simmental group II in terms of the absolute weight of both the axial and peripheral skeleton over purebred and crossbred bulls and castrated bulls of the Bestuzhevskaya breed, crossbred castrated bulls has been established. For the entire mass of the carcass skeleton, this superiority was, respectively, 12 g (2.4%), 6616 g (14.7%) and 5553 (12.0%). Similar intergroup differences were found in the length of individual parts and the entire skeleton of the carcass.

Abstract

The article presents data on the efficiency of a repeated series of transvaginal ultrasound-guided recovery of oocytes (OPU) in donor heifers of the Simmental breed. Two series were performed — five OPU sessions with an intensity of once a week and a two-week rest period between series. During the repeated series of OPUS, 1.7 fewer follicles were visualized in donor heifers on average per session compared to the value of this indicator established in the first series (7.0 versus 5.3 follicles, p < 0.05). A decrease in the number of ultrasound-visible follicles during repeated series at the trend level was noted in all five OPU sessions. During the repeat series, 0.4 fewer oocyte-cumulus complexes (OCCs) were obtained from one donor on average per session (3.1 versus 2.7 OCCs). There were no differences in the quality of OCCs between the two OPU series: the proportion of OCCs suitable for further use was 67.0% and 63.5%, respectively, while in individual OPU sessions the differences between the series were multidirectional. Fertilization of oocytes and further in vitro cultivation showed a significantly higher degree of the first division — crushing during the 1st series of OPU (p < 0.05), however, these differences were leveled with further cultivation: the yield of blastocysts was, respectively, 23.6% and 21.7%. Considering the absence of significant differences in the quantitative characteristics of the obtained oocytes, as well as their developmental competencies in vitro, conducting a repeat series of OPU after a two-week rest period may be recommended for obtaining oocytes in donor heifers of the Simmental breed.

Abstract

Currently, genome-wide association analysis is a modern and reliable method for analyzing genomic information about animals, as well as determining the “genotype — phenotype” relationship. This study aims to use the GWAS method to identify significant SNPs located within or linked to genes for meat traits in Large White pigs — backfat thickness over the 6–7th and 10–12th vertebrae, and loin muscle depth. The conducted GWA analysis revealed 60 genes, of which 17 are associated with biological functionality, annotated using the DAVID program. Three genes were found to have codification in the Pig QTL database. The genes were divided into 10 groups based on gene ontology (GO). Of all the genes, the AUTS2 gene, located on chromosome 3 and predicting the number of corpora lutea in sows, is of greatest interest. The results of this scientific work will contribute to the development of a genetic evaluation system and improvement of meat qualities in pigs.

Abstract

The purpose of this study was to study the dynamics of the comparative level of expression of the EGR1 gene in the tissues of rainbow trout at different ages. The EGR1 gene encodes a transcription factor that influences the transcription of a large number of genes from both the 5-bar and 3-bar ends of genes. A random sample of fish aged 6, 12 and 18 months was taken for the study. To assess the expression level of the EGR1 gene, located on 14 chromosomes, a housekeeping gene was taken: G6PD. A comparative analysis of the expression level of the EGR1 gene in rectal tissues revealed a significant change in different age periods of rainbow trout. Expression in the tissues of the rectum at the age of 6 months was maximal, and at the age of 12 months it was minimal, but no significant differences were found (p = 0.2648). As a result of the analysis of changes in the level of relative expression of the EGR1 gene in the heart tissues of rainbow trout at different ages, it was found that in the group of fish aged 6 months, the expression level was maximum at the stage of 12 and 18 months (р < 0.01). As a result of the study, a correlation between the size and weight parameters of rainbow trout and the level of gene expression in different eras and in different countries was established. Expression dynamics at different ages in rainbow trout were also determined.

Abstract

Relevance. The research was carried out in order to analyze the impact of technologies for the development of virgin and fallow lands on erosion processes in the steppe zone in the 60s and modern conditions.

Methods. The analysis of approaches to the prevention of soil degradation and desertification of the territory is carried out based on materials obtained in the steppe zone of the Republic of Khakassia in the second half of the XX century and in modern conditions. We used the results of the application of technologies for the development of virgin and fallow lands of Tselinnoye LLC in different periods. Information about dust storms was taken from data from the Bey and Shire weather stations. In 1954–1960 when plowing the chernozem of the southern virgin lands, technology was used using plows, huskers and other tillage tools. The lack of adapted ways of developing and using new lands has led to an outbreak of wind erosion of soils over large areas, including in the south-east of the country.

Results. The dump system of soil treatment during the mass development of virgin and fallow lands in the 60s, without taking into account soil, climatic and other conditions, led to a strong development of wind erosion. The number of days with dust storms in Khakassia reached up to 4.8–11.6 per year. In modern conditions, the removal of highly ventilated soils from arable lands and the use of strip placement of crops and minimal tillage on the rest of the arable land contribute to increasing the erosion resistance of agricultural landscapes. The use of the Tornado 500 herbicide in August during the development of the deposit reduces the erodibility by 2.5 times, compared with the technology with its introduction in early summer.

Abstract

Relevance. The development of new varieties and their rapid introduction into production remains the most effective resource for improving productivity, energy saving, profitability and competitiveness. The purpose of the current study was to develop the winter bread wheat variety Rubin Dona and evaluate its productivity and basic adaptive, technological, and baking properties.

Methods. The current study was carried out in the fields of research crop rotation of the department of winter wheat breeding and seed production in 2018–2023. The variety was developed by the method of intravarietal hybridization using the productive and adaptive variety Nakhodka as a maternal form and the high-quality strong wheat variety Donskaya Yubileynaya as a paternal form and a subsequent individual selection.

Results. There has been established that the variety Rubin Dona has a high and stable level of productivity. For 6 years of competitive variety testing the mean productivity of the variety sown in green manure fallow was 9.45 t/ha with the minimum of 6.77 t/ha and the maximum of 11.80 t/ha, compared to the standard variety Ermak with 8.80, 6.06 and 11.21 t/ha, respectively. The variety Rubin Dona sown after various forecrops also demonstrates a reliable and stable productivity increase to the standard, 0.67 t/ha after maize for grain, 0.79 t/ha after peas, 0.62 t/ha after sunflower, 0.77 t/ha after winter wheat. There has been revealed that the advantage of the new variety, which provides high and stable yields, is its high environmental resistance to regional soil and climatic conditions such as drought, low temperatures, spring frosts, diseases, and lodging. The variety has lower indicators of the coefficient of variation, factor of stability (FS), yield range (d) with a high level of realization of productivity potential in comparison with both the standard variety Ermak and the highly productive variety Razdolie, which has a contrasting periods of heading and ripening. The technological and baking properties of the new variety are of high quality and meet the requirements of GOST-9353-2016 referring to the first class. Since 2023, by decision of the State Commission of the Russian Federation for testing and protection of breeding achievements, the variety has been included in the State List of the varieties approved for use in the Central Blackearth (5) and Lower Volga (8) regions.

Abstract

Sanitary monitoring of spring wheat agrocenosis in the zone of unstable moisture was carried out to determine the degree of development and prevalence of diseases. The fungicidal activity and effectiveness of seed protectants of various classes against seed infection on spring wheat variety Yasenka have been studied. The results of the research established the effectiveness of the disinfectant DVD Chance, KS, corresponding to 85.7% relative to the effectiveness of the standard Polaris, ME Eco Plus (100 g/l prochloraz + 25 g/l imazalil + 15 g/l tebuconazole) (84.6%). An increase of 15–20% in damage to spring wheat plants by root and basal rot caused by fungi of the genus Fusarium in the “tillering” phase and its dependence on the climatic conditions of the growing season was established.

By the “flag leaf” phase, the prevalence of root and basal rot caused by fungi of the genus Fusarium increased to 20,5%, and the degree of development — to 7–9%.

Evaluation of the effect of the fungicide DVD Chance, KS (30 g/l difenoconazole + 6.3 g/l cyproconazole) by pre-sowing treatment of spring wheat grain of the Yasenka variety established the effectiveness of the drug at a consumption rate of 1.0 l/t against molding of seeds, corresponding to 85.6% , in the reference variant the indicator is 84.6%, with the development of the disease in the control — 34.5%. By harvest, the effectiveness of the drug remained and reached 79.2%, in the standard — 78.3% with the development of the disease 43.7%. Research contributes to the expansion of the range of fungicides for treating grain crops, the development of regulations for use and the possibility of recommending them for registration tests for further inclusion in the State Catalog of those approved for use.

Abstract

Individual features of growth, development and dry matter accumulation by sunflower hybrids of one maturity group on typical, medium-humus, medium-loamy chernozem were studied. The research was carried out in a link of grain-plowing crop rotation on the lands of farm S.E. Nekipelov Pristensky district of Kursk region in different hydrothermal conditions in 2020–2022. The object of the study were sunflower hybrids (Sumico-Syngenta, P63LE10-Pioneer and Elion-Galaktika), sown to a depth of 4–5 cm when the soil was heated to 10 °C in the amount of 60 thousand pcs/ha of germinating seeds. The work was carried out in the technology of yield planning 40 c/ha, with the introduction of liquid complex fertilizers (HCS NР 11:37) before sowing in the amount of 50, 100 and 150 l/ha per depth 5, 10 and 15 cm. In the experiment, the traditional technology of preparing the soil for salting with the regulation of the number of the weed component by Express Sun technology was used. Due to the increased growth energy of the hybrids under consideration, the height of plants varies according to the phases of development and maturation in the studied variants reached 177–191 cm, which is 4.7–6.5% higher than the control values. The mass of plants in the sunflower agrocenosis increased in the Sumiko hybrid by 13.2%, P63LE10 by 11.1%, Elion by 12.5%. The plants of the hybrid Elion accumulate more dry matter in the aboveground mass. The use of HCS at a maximum dose of 150 l/ha when applied to a depth of 15 cm contributed to an increase in the accumulation of dry matter by the maturation phase in the plant biomass of the Sumiko hybrid by 304.3 g/m², the P63LE10 hybrid by 177.7 g/m², the Elion hybrid by 354.0 g/m², or, respectively, by 34.7%, 17.2% and 33.7% relative to the control.

Abstract

Relevance. The creation of high-quality oilseed flax seeds using new plant breeding methods is an imperative principle with the advent of better crop seed production. Current methods for creating such seeds continue to be complicated and laborious. In this regard, the development of more advanced methods for obtaining renewed seeds with a high level of manifestation of sowing, various types and morphophysiological properties is relevant and has practical importance.

Methods. The experiments were carried out in accordance with the methods of planting, conducting field experiments with flax, and methodological recommendations for seed production of oil flax. The assessment of sowing quality and seed material was carried out in accordance with the current certification system , varietal quality — by the soil control method.

Results. The high efficiency of creating updated oilseed flax seeds using the method of plant selection during the growing season — from the beginning to the end of full flowering, which allowed for a significant increase in their yield to 61.5%, compared with the control. Selection of plants in the interval from the beginning to the end of full flowering ensured the preservation of the sowing qualities of the created seeds at the control level — selection according to the current method, as well as increasing the uniformity of indicators of the morphophysiological properties of seeds, including the uniformity of seed sprouts along the length by 4.6%. The selection method with the removal of plants atypical in morphological charakteristics compared with the control allowed to increase the yield of updated oilseed flax seeds by 29.7%, improve their morphophysiological properties. The varietal quality of the updated seed material for all methods of its creation was characterized by the absence of atypical seeds in color and minor differences between the options in the uniformity of varietal characteristics.

Abstract

One of the main agrotechnical activities carried out in the garden is tree pruning. When studying the variety-double combinations of apple trees in certain environmental conditions, it is necessary to take into account the strength of growth, the density of fouling, the type of branching, the structure of fruit formations, which depends on the varietal characteristics and technologies of growing plantations.

The author presents the results of studying the parameters of the influence of the degree of pruning of Golden Delicious apple trees grafted on low-growing rootstocks SK-7 and M-9, depending on the rootstock, on growth processes, productivity and marketable qualities of apple fruits. The reaction of plantings to pruning was determined depending on the biological characteristics of the variety and on the degree of branch removal and their orientation. With an increase in the intensity of pruning, the leaf surface area per fruit on the rootstock SK-7 was 180–750 cm², on the rootstock M-9 — 172–619 cm², respectively. The yield of apple trees from one tree on the rootstock SK-7 was 13.2 kg with a minimum shape, 11.4 kg with an average, 10.5 kg with a maximum, and 11.4 kg, 9.5 kg and 7.7 kg on the rootstock M-9, respectively. The average weight of fruits grafted on the rootstock SK-7 increased by 1.9 times, and on the rootstock M-9 — by 1.3 times.

It was noted that the life cycles of trees on the low-growing dwarf rootstock SK-7 were 10–12% higher than on the rootstock M-9.

Abstract

Relevance. One solution to the problem of selenium deficiency is the enrichment of socially important food products, in particular dairy products, with bioavailable forms of selenium. Such forms include selenium nanoparticles. The aim of the work is to develop a dairy product enriched with selenium nanoparticles stabilized with chitosan.

Methods. According to dynamic light scattering spectroscopy, a sample of selenium nanoparticles stabilized with chitosan has a monomodal size distribution with an average hydrodynamic particle radius of 25 nm.

Results. Quantum chemical modeling of selenium nanoparticles stabilized by chitosan has revealed that the most energetically favorable interaction is the interaction of the surface of selenium nanoparticles with the hydroxo group attached to the C3 glucosamine residue of chitosan. A study was conducted of the influence of technological parameters on the stability of selenium nanoparticles stabilized with chitosan. It was found that increasing the exposure time leads to an increase in the average hydrodynamic radius of selenium nanoparticles stabilized by chitosan. In the case of pH, an inverse relationship is observed: particles with the largest average hydrodynamic radius are found in samples with an acidic environment (pH ˂ 5). As part of a study of the influence of technological parameters on the stability of selenium nanoparticles stabilized by chitosan, it was found that selenium nanoparticles stabilized by chitosan can be used as a source of selenium for food products that have a neutral pH, but can be subjected to heat treatment at temperatures above 70 °C in for 5–15 minutes, in particular pasteurized milk. A study of pasteurized milk fortified with selenium nanoparticles stabilized by chitosan showed that there were no significant changes in titratable acidity, surface tension and pH of milk, as well as the average hydrodynamic radius of casein micelles after milk fortification. The value of antioxidant activity increases by 0.88% — from 6.50 to 7.38%.

Abstract

The purpose of scientific work is a comprehensive analysis of the impact of changes in the structure of acreage and the land use system on ensuring the sustainability of the agricultural industry in Russia. The results obtained demonstrate that, despite the implementation of a number of legislative initiatives aimed at improving the efficiency and environmental orientation of agriculture, a number of unresolved problems remain in the Russian Federation that hinder the transition to a model of sustainable agricultural production. Inefficient use of land resources is a problem faced by many agricultural regions in Russia. Irrational structuring of land, unbalanced distribution of agricultural land, low efficiency of use of modern technologies and resources lead to the loss of land potential. This has a negative impact on the yield and quality of agricultural products. There may be insufficient attention to the environmental aspects of land management: conserving biodiversity, maintaining natural ecosystems, minimizing the ecological footprint of agricultural activities and applying methods that promote soil regeneration. The comprehensive improvement of land management mechanisms in the Russian Federation, taking into account the concept of sustainable agriculture, involves the development and implementation of policies aimed at stimulating sustainable agricultural practices, supporting innovative methods and technologies, as well as training and advising agricultural producers on sustainable agriculture. This approach will significantly improve land use efficiency and ensure the sustainable development of Russia's agricultural sector.

Abstract

In recent years, there has been a problem of reducing the marketability of agricultural products of farms for many types of goods. Among the key food products supplied by farmers, the negative dynamics of sales was noted for the sale of potatoes and vegetables. This situation is largely related to the annual fluctuations in agricultural production, which is especially evident in the cultivation of fruit and vegetable crops. Using econometric modeling based on the construction of regressions based on panel data, the article shows the negative impact of changes in production volumes on the percentage of marketability of farm products. Farmers, like other small-scale enterprises, do not have a developed marketing infrastructure, unlike agricultural organizations. Therefore, farms are particularly sensitive to fluctuations in production volumes, which create for them the problem of lack or excess of resources for sales. An important way to solve this problem is the activity of trade organizations aimed at implementing social functions to support the sale of farm products. In Russia, such social practices are being implemented by the largest representatives of the retail industry in a pilot mode in certain regions of the country. In particular, in some areas, agricultural aggregators are operating, launched by the “X5 Group” and “Magnit” retail chains, which perform technological and marketing functions to ensure the sale of farm goods. There are other social projects of trade organizations, for example, “Agrocontract” and “Farmer›s Island”, initiated by “X5 Group”, which involve the conclusion of direct contracts with farmers in order to reduce the purchase prices of goods and provide for the purchase of various unique goods from farmers. The expansion of the social functions of trade organizations will significantly overcome the existing problems of marketing farm products and provide such farms with sufficient income and profit for further self-development of activities.
