The article presents the results of observations of the seasonal dynamics of the growth of annual shoots of two species of shrub willows: Salix triandra and Salix viminalis. Object: genetically aligned model inbred-clonal populations of S. triandra and S. viminalis. Material: growing shoots on annual cuttings. Methods: comparative morphogenetic, chronobiological, numerical analysis of the series of dynamics. Results. Clones of two species of shrub willows, phylogenetically distant from each other, demonstrated high productivity along the length of shoots on annual cuttings. On the shoots of the strongest clone of S. triandra, the length of mature shoots was 176–215 cm, on the shoots of the strongest clone of S. viminalis - 132–192 cm. As the shoots grow, the differences in length between them increase. No significant influence of the clone factor on the dynamics of the daily growth of S. triandra shoots was revealed, and the effect of the clone factor on the dynamics of the daily growth of S. viminalis shoots is insignificant. In the seasonal dynamics of the daily growth of shoots, regardless of their species and clonal affiliation, three stages of shoot development were identified: spring, early summer, and late summer. The transitions between stages are synchronized in clones regardless of species. Qualitative interspecific and interclonal differences in the seasonal dynamics of daily shoot growth were not revealed. Quantitative interspecific differences in the seasonal dynamics of daily increment were revealed only at the second stage of shoot development, with high values of daily increment. Significant interclonal differences in the seasonal dynamics of daily growth were not found: differences between the trajectories of shoot development are due to intraclonal variability within each species. Recommendations. When planning, creating and operating pure and mixed cultures of S. triandra and S. viminalis, take into account the fundamental similarity in the seasonal dynamics of the development of shoots of different species of shrub willows. When harvesting and planting cuttings, use a homogeneous mother material. Culling of weak cuttings that are lagging behind in development should be carried out in the first year of life.

The development of an inflammatory process in the liver tissue and bile ducts in cats is a frequent and severe pathology that requires early diagnostic and therapeutic approaches. It is shown that the diagnostic approach for feline cholangiohepatitis should be comprehensive and based on a thorough analysis of anamnestic data, the results of physical examination and additional methods of instrumental and laboratory diagnostics. It is important in the diagnosis of cholangiohepatitis in cats to conduct visual diagnostic methods, in particular ultrasonography. It is established that the method of ultrasonographic diagnostics is of high value in the verification of acute cholangiohepatitis in domestic cats. Hepatomegaly was detected in 23.5% of sick cats, the severity of this sign positively correlated with the severity of the course of cholangiohepatitis. Microhepathy in patients with feline cholangiohepatitis was observed with a frequency of 5.9%, hyperechogenicity of the liver – 17.6%, hypoechogenicity of the liver – 7.8%, dilatation of the bile ducts – 23.5%, thickening of the gallbladder wall – 9.8%, pathological echogenicity of the gallbladder wall – 3.9%, echogenic debris in the gallbladder cavity – 32.4%, change in the echogenicity of the pancreas - 31.4%, increase in the size of the pancreas – 15.7%, thickening of the duodenal wall – 11.8%, pathological layering of the duodenal wall – 7.8%, hyperechogenicity of parapancreatic fat – 5.9%, peritoneal effusion – 5.9%.

The article discusses the use of digital aerial photography and aircraft laser scanning to assess the state of rice systems. An analysis of the state of affairs in rice growing shows that today there is not enough financial resources not only for the reconstruction and technical re-equipment of outdated elements of rice systems, updating technologies and equipment in accordance with the achievements of science and best practices, but also to maintain the existing technical level of the systems. The article presents the results of a study of planning technology options and the prospects for its improvement based on the introduction of laser control systems. Rational use of water, material and labor resources is the main reserve for increasing the efficiency of rice systems. The resource-saving potential contributes to the intensification of the production activities of water users. Rice is the most productive and most water-intensive crop. Rice cultivation in Russia was most widespread in the Kuban, occupying a technologically advanced position. Rice irrigation systems occupy once unproductive lands with a thin humus horizon, with a low humus content and unfavorable water-physical properties, prone to swimming and the formation of a surface soil crust. Research has shown that significant improvements in planning quality in the construction of rice paddies can be achieved with laser control systems. As part of the modern development of aerial survey work, a network of base stations, reference and control points is being created to conduct a technical survey of the structures of the rice system. Measurements are made using GNSS satellite measurements. The distance between base stations is no more than 60 km, between control points – no more than 20 km. At each 20-kilometer aerial survey site, it is necessary to provide four planned altitude landmarks and one control point. Identification marks and control points should be applied on the ground, the coordinates of these points should be determined by instrumental geodetic methods for conducting a technical survey of the structures of rice systems.

For veterinary practice, the antimicrobial agent "Cliodeziv" (the developer organization is Pharmpromvet LLC) in the form of a powder for use in the form of a fumigation aerosol is proposed. The product as an active substance contains 40% of crystalline iodine. During thermal sublimation, iodine vapors are formed, which have a high penetrating ability and sanitizing properties. Studies have been conducted to evaluate the effectiveness of the use of the "Cliodeziv" agent in the rehabilitation of poultry houses by determining the bacterial contamination of the air and the walls of the poultry house before and after treatment. It was found that the agent "Cliodeziv" has a pronounced bactericidal activity, since it causes a significant decrease in the microbial contamination of the air and walls of the poultry room. The total microbial contamination of the air in the poultry housing decreased by 64.9% and amounted to 202 CfU, compared to 575 CfU before the experiment. The bacteriological assessment of flushes from the wall surfaces showed a decrease in bacterial contamination by 65.1%, from 1100 CfU to 384 CfU after treatment. The drug "Cliodeziv" did not have a negative effect on the biochemical parameters of the bird's blood. Under the influence of the iodine included in the product, an increase in the level of metabolic processes was noted. By the end of the experiment, the total protein content in the blood serum increased by 16.2%; cholesterol decreased by 25.25%; glucose increased by 29.86%. The test agent promotes the activation of the antioxidant protection system of birds, the activity of the enzyme glutathione peroxidase increased by 40.71% by the end of the experiment. By the end of the experiment, AlAT decreased by 35%, AsAT decreased by 21.58%, which indicates a positive effect of the drug on the muscle tissue and productivity of poultry. The product "Cliodeziv" does not have a negative impact on the veterinary and sanitary indicators of poultry meat. Organoleptic and biochemical parameters of poultry meat confirmed its good quality.

Goat breeding is a topical trend in agriculture at the present time. Goat milk is in demand because of its dietary properties, and goat meat also has high taste. However, the development of both dairy and beef goat breeding in Russia on large farms is insignificant. To develop recommendations on the technology of breeding goats in the Rostov region, studies of the indicators of meat and dairy productivity of the most popular breeds of Lamancha and Zaanen goats were presented at the FSBEI VO Donskoy State Agrarian University on the basis of IP Panchenko. It has been established that the experimental goats can be attributed to mid-season animals, and the content of internal fat in the carcasses of goats increases with age. In the meat of young Lamancha goats, the protein and dry matter content is higher, therefore, young Lamancha goats are superior to those of the Saanen breed. Goats of the Saanen breed surpass the Lamancha goats in milk yield in 305 days and have higher average daily milk yields, but the Lamancha goats have superiority in milk fat yield in 305 days of lactation. Also, the milk yield of goats of the Saanen breed for 20 days of lactation is greater than that of goats of the Lamancha breed. To increase the production of goat meat, it is necessary to practice fattening super-repair young Lamancha goats from 6 to 8 months of age. In order to obtain competitive, high quality goat meat, young animals should be intensively raised, fattened and slaughtered for meat between 7 and 10 months of age. For dairy goat breeding, it is more effective to use Saanen goats for purebred breeding.

The development of socially significant food products based on the introduction of breeding and genetic innovations and the use of modern biotechnological techniques will reduce the cost of production, the costs of transporting, storing and processing raw materials, and also, due to the increase in the profitability of all links in the technological chain, will increase the competitiveness of domestically produced food products. Increasing the production of meat products, expanding the range, increasing their biological value, as well as creating new generation products that meet the requirements of a healthy diet, are urgent tasks for the meat industry. The article is devoted to the study of the biological characteristics of sheep of different genetic potential and the development of a recipe and technology for a lamb meat product using non-traditional plant components. In order to increase the production volumes of the sheep breeding industry, it is necessary to use the genetic potential of breeds of domestic and foreign breeding, which affects the economic and biological characteristics and the level of animal productivity, to the maximum. We have studied the productive characteristics of sheep of different genetic potential in the production of competitive mutton and products of its processing. The article substantiates a new rational technology for the production of meat loaves using inulin and pumpkin powder. Despite the development of the production of synthetic forms of food additives, interest in the expanded use of non-traditional types of plant materials is constantly growing. The study was conducted at the Department of Food Technologies and Commodity Science, Don State Agrarian University. Experimental samples were made containing different amounts of herbal ingredients, the dose of inulin and pumpkin powder was established in the product, and the organoleptic evaluation was determined. On the basis of organoleptic and physico-chemical studies, a rational formulation of the product is proposed.

The results of experimental studies on the influence of variable temperatures of egg incubation (37.8°C - 1...14 days; 39.5°C for 2 hours daily - 15-17 days; 37.5°C - 18 days; 37.0 °C - 19-20 days) on the growth and development of chicken embryos of egg crosses "Hisex Brown" and "Lohmann Brown" in different periods of embryogenesis. Under conditions of variable temperature incubation of eggs in the embryos of hens of the Lohmann Brown cross, compared with the Hisex Brown, there was a statistically significant increase in the absolute values of body weight by 12 (p=0.011), 14 (p=0.001), 15 (p= 0.000), 20 (p=0.000) days, body length - on days 6 (p=0.000), 8 (p=0.000), 9 (p=0.025), 13…16 (p=0.000) days. Differences in the rhythm of the growth of chicken embryos were established, accompanied by 5 critical stages of the growth rate of body weight and 6 critical stages of the growth rate of body length in the Haysex Brown cross, and in the embryos of the Lohmann Brown cross - 4 and 1 critical stages, respectively. Throughout the studied period of embryogenesis in the studied crosses, the highest intensity of the growth rate of weight and body length was noted in the embryonic period of development with a decrease towards the hatching period. The highest specific weight growth rate in the embryonic period is typical for embryos of chickens "Hisex Brown" (p=0.000), and body length - for embryos of the cross "Lohmann Brown" (p=0.047). In subsequent periods of embryonic development, the specific rate of growth in body weight and length decreased in both crosses. Differences in the specific rate of body weight growth in embryos of chickens "Hisex Brown" and "Lohmann Brown" in the prefetal (p=0.680) and fetal periods (p=0.477) were not found, and in the specific rate of body length growth - in the prefetal (p= 0.709), fetal periods (p=0.942) and hatching period (p=0.918). By the hatching period, the specific body weight growth rate prevailed in the Lohmann Brown embryos (p=0.000). The effect of exposure to variable incubation temperatures was accompanied by a higher percentage of chick hatchability of the Lohmann Brown cross (94.90%) compared to the Highsex Brown cross (91.90%). The results obtained indicate the feasibility of using the proposed mode of incubation with variable temperatures for cross-country chickens "Lohmann Brown".

Under conditions of variable temperature incubation of eggs in the embryos of hens of the Lohmann Brown cross, compared with the Hisex Brown, there was a statistically significant increase in the absolute values of body weight by 12 (p=0.011), 14 (p=0.001), 15 (p= 0.000), 20 (p=0.000) days, body length - on days 6 (p=0.000), 8 (p=0.000), 9 (p=0.025), 13…16 (p=0.000) days. Differences in the rhythm of the growth of chicken embryos were established, accompanied by 5 critical stages of the growth rate of body weight and 6 critical stages of the growth rate of body length in the Haysex Brown cross, and in the embryos of the Lohmann Brown cross - 4 and 1 critical stages, respectively. Throughout the studied period of embryogenesis in the studied crosses, the highest intensity of the growth rate of weight and body length was noted in the embryonic period of development with a decrease towards the hatching period. The highest specific weight growth rate in the embryonic period is typical for embryos of chickens \"Hisex Brown\" (p=0.000), and body length - for embryos of the cross \"Lohmann Brown\" (p=0.047). In subsequent periods of embryonic development, the specific rate of growth in body weight and length decreased in both crosses. Differences in the specific rate of body weight growth in embryos of chickens \"Hisex Brown\" and \"Lohmann Brown\" in the prefetal (p=0.680) and fetal periods (p=0.477) were not found, and in the specific rate of body length growth - in the prefetal (p= 0.709), fetal periods (p=0.942) and hatching period (p=0.918). By the hatching period, the specific body weight growth rate prevailed in the Lohmann Brown embryos (p=0.000). The effect of exposure to variable incubation temperatures was accompanied by a higher percentage of chick hatchability of the Lohmann Brown cross (94.90%) compared to the Highsex Brown cross (91.90%). The results obtained indicate the feasibility of using the proposed mode of incubation with variable temperatures for cross-country chickens \"Lohmann Brown\".","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75000096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The content of the article includes the results of phytosanitary monitoring of spring wheat crops in various soil regions of the Republic of Mordovia for the presence of a pathogenic complex of root rots. In the course of the studies, the dependence of the damage to spring wheat due to the site of infection of the plant organ was revealed. Their occurrence and species structure depended on the type of soil. A direct connection was revealed to increase the occurrence of Bipolarissorokiniana species on chernozems, and Fusariumspp on sod-podzolic soils. Numerous sampling and data processing have demonstrated the diverse structure of fungal communities belonging to root rot pathogens. During the research, 6 species of the genus Fusarium of the local population were first identified. A comparative assessment of the occurrence of species of the genera Fusarium and Helminthosporium showed an increase in the proportion of dominant typical species on sod-podzolic and chernozem soils and a decrease in the presence of rare and random species in them. On gray forest soils, there were no obvious changes in the composition of the pathogenic complex of root rots.

The article is devoted to the development of technology for enriched fermented milk ice cream. The production of functional products is an urgent problem in the modern food industry. Such products must have not only functional properties, but also good organoleptic characteristics. Most types of ice cream are high in calories, high in food additives such as synthetic sweeteners, colors, flavors and stabilizers. One of the promising ways to increase the volume and improve the quality of fermented milk ice cream that meets modern requirements for a healthy diet is its enrichment with probiotic microorganisms and natural biologically active substances. In the formation of the organoleptic indicators of fermented milk ice cream, the key role belongs to the microflora of the starter cultures used, the correct selection of which affects the quality indicators of the finished product. The optimal dose of introducing fig syrup into fermented milk ice cream has been substantiated, which was determined on the basis of organoleptic indicators. The optimal amount of fig syrup was established without deteriorating the technological and consumer properties of fermented milk ice cream. The developed scheme for the production of fermented milk ice cream with fig syrup includes the acceptance and preparation of raw materials, normalization, filtration, homogenization, pasteurization, cooling to the fermentation temperature, adding fig syrup under aseptic conditions, fermentation, fermentation, adding a stabilizer-emulsifier, cooling, maturation of the fermented milk mixture, freezing, packaging and labeling. Enrichment of fermented milk ice cream with fig syrup, gives the product functional properties and allows you to expand the range of ice cream, which, with systematic use, has a beneficial effect on the body. It was found that the use of fig syrup in the technology of fermented milk ice cream improves the consistency and taste of the product. A recipe for enriched fermented milk ice cream and its production technology have been developed.

The work was carried out in the laboratory of veterinary medicine VNIIOK - a branch of the Federal State Budgetary Scientific Institution "North Caucasian FNAC", as well as in the farms of the Kochubeevsky district of the Stavropol Territory. The object of the study was cattle of various age groups, blood and its serum. 4 groups of 12 animals each were created: 1st group: newborn calves; 2nd group: calves 4-6 months; 3rd group: heifers (15-18 months); 4th group: cows 4-5 years old. Each group was divided into 4 subgroups of 3 animals, while the 1st subgroup received Immunofan, the 2nd subgroup - Biferon-B, the 3rd - Ligfol, the 4th - control, the animals of which were injected with sterile saline. Analyzing the dynamics of hematological parameters of infected newborn calves and calves 4-6 months. of age, it should be noted that the immunomodulators Immunofan and Biferon-B provoke prolonged leukocytosis in the physiological range. In the 1st subgroup of calves, by the 14th day of the experiment, the ESR decreased significantly. The use of Ligfol in calves contributed to an increase in the level of hemoglobin in the blood. Immunotherapy with Immunofan and Biferon-B of VL-infected heifers contributed to a decrease in the level of leukocytes and ESR, Ligfol caused a decrease in ESR and an increase in hemoglobin. The use of Immunofan and Biferon-B preparations in infected cows 4-5 years old provoked leukocytosis, a decrease in ESR, Ligfol activated hematopoiesis and contributed to a decrease in ESR, but the changes were not prolonged. The conducted studies allow us to draw the main conclusions: the use of immunomodulators Immunofan and Biferon-B to VL-infected young animals from birth to 4-6 months contributes to the normalization of the clinical condition and activates the immune system; helps to reduce the number of infected livestock (newborn calves); introduction of Ligfol to VL-infected young animals from newborn to 15-18 months. weakly enhances the immune status, but improves the clinical condition of animals; immunotherapy of VL-infected heifers with Immunofan and Biferon-B helps to reduce immune tension caused by a viral infection and contributes to an increase in natural resistance; Immunofan and Biferon-B immunomodulators in order to improve the immune status and normalize the clinical condition, it is advisable to use VL-infected calves from newborn to 6 months and heifers (18 months).
