Recreational areas contribute considerably to the establishment of sustainable and comfortable urban environment. Green stands and soils of recreational areas provide important environmental functions and ecosystem services, their utilization depends on natural and anthropogenic factors distinguished by land-use history. For the case of the recreational areas of New Moscow, a comparative analysis of trees (n=1909) and soils (n=39, 0-10 cm layer) of the parks, established on former forested and fallow lands, was performed. It was shown that the species diversity was higher although the tree condition score was lower in the forest-parks, compared to the parks established on former fallow lands, which were generally characterized by a higher level of maintenance. Soils of these parks had a neutral pHH20 (7.20.8) and high content of organic matter (8.52.5 %), whereas the forest-parks soils were similar to the natural Retisols of the forest area with pHH20 6.40.2 and 5.10.2, organic matter content 5.90.2 и 3.50.2 %, respectively. Soils of the parks, established on the former fallow lands, had also a higher pollution level by particular heavy metals as well as considering the integral pollution index. Thus, a higher level of maintenance of the parks established on former fallow lands coincided with a higher anthropogenic pressure and ecosystem alteration. However, reorganization of forests into forestparks allowed partial preservation of the natural ecosystems. That is necessary to consider for planning the new urbanized areas in Moscow.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45423652","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 article considers the features of clinical manifestation of subcompensated intestinal dysbiosis in cats in assessing the effectiveness of its treatment. The studies were carried out on the basis of Department of Veterinary Medicine, RUDN University, and the clinical work was conducted at private veterinary clinics: Avettura, Epiona, In the World with Animals. Cats were selected for the experiment as they arrived at the initial appointment at veterinary clinics. The diagnosis of suspected intestinal dysbacteriosis was made considering anamnesis, clinical examination, and microbiological tests. The severity of intestinal dysbacteriosis was assessed on the results of clinical and laboratory studies. During the research, clinical and diagnostic approaches for subcompensated intestinal dysbacteriosis in cats were improved. Furthermore, effective ways of its treatment were developed. For subcompensated intestinal dysbacteriosis, administration of Lactobifadol probiotic, Vetelakt prebiotic and Azoksivet immunomodulator showed the greatest therapeutic effect, which led to an overall clinical improvement in 5.50 days. Therapeutic efficacy of B3 regimen was also clearly evidenced by the positive changes in intestinal microbiota and hematological blood parameters during the pharmacorrection. Improvement of clinical diagnostic approaches, prognosis of intestinal dysbiosis of varying severity and treatment effectiveness in cats require will allow to study intestinal dysbiotic disorders in other animal species.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45355148","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}

A reduced level of copper and zinc was found in animals from both farms throughout the entire study period. The dependence of the content of microelements on the physiological state of animals (before and after calving) was not revealed. It was shown that the content of iron in the blood of highly productive cows from farm 2 was lower throughout the study, and manganese - a week and a month after calving.

The components of economic damage under stress are a decrease in overall resistance and productivity, deterioration in product quality, an increase in labor costs and funds per unit of production, an increase in animal morbidity and mortality. The studies were carried out on the basis of Belozernoe farm in the Salsky district, the Rostov region. A complex of clinical and laboratory studies was performed on 18 sheep (10 Romanov and 8 Tsigay breeds) aged 2 to 3 years, before and after a planned routine shearing. Stress in sheep caused by planned shearing was clinically manifested by general depression, in some cases, subfebrile fever, moderate tachypnea and tachycardia. It was shown that stress was accompanied by anemia, the development of erythropenia and leukopenia. Immunocompetent cells in the blood of experimental animals during stress development were analyzed. Severe lymphocytopenia was found to occur after a haircut. In addition, in the blood of experimental animals under stress, a tendency to a decrease in T-total cells was noted, which was accompanied by an increase in 0-cells, which was significant in sheep of the Tsigay breed (p0.05). When analyzing the main immunoregulatory T cells in sheep under stress, a significant increase in T-suppressors was revealed with a relatively stable level of T-helpers in the blood studied. Thus, a significant (p0.05) increase in the level of T-suppressors in sheep of Romanov and Tsigay breeds was recorded; it was by 1.15 and 1.19 times higher compared with the initial data. It should be noted that we did not find any significant differences between animals of Romanov and Tsigay breeds in stress development after shearing. The obtained data should be taken into account in the further search for methods of stress correction in sheep.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49385210","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}

Busch, P. saxatilis Kom. were analyzed in the article. The initial material was obtained by seed exchange with botanical gardens in Russia, the CIS and foreign countries. Phenological observations were carried out according to generally accepted methods, on the basis of which the phenological spectrum of seasonal development of plants were constructed, and survival points (SP) were assessed. The introduction coefficient (IC) was calculated, which reflected the introduction value of the considered group of plants. The method of ecological-geographical analysis was used to compile the introduction forecast. Among the studied species, Primula nutans (SP=11) obtained from the seeds of cultivated plants from Scandinavian countries and P. jesoana (SP=9) were most adapted to the conditions of the Kola Arctic. Two species ( P. borealis, P. patens (SP = 4)) were poorly adapted to the conditions of the region, P. farinosa (SP = 1.0) and P. saxatilis (SP = 1.5) were not tested enough due to a short study period. The study showed that plants living from the tundra to the steppe zone ( P. nutans - I C = 1.57) and, in some cases, plants of the taiga zone reaching the subalpine belt in the mountains ( Primula jesoana - I C= 1.28) were adapted to local conditions.

In order to stop desertification, forest reclamation works were carried out in the Caspian region in the mid-20th century, and significant areas of Krascheninnikovia ceratoides (L.) plantings were created. The Pamirian winterfat is a wide distributed plant. It has a well-developed root system, providing sufficient water in climatic conditions of the arid zone. The article provides a systematic assessment of the long-term impact of afforestation and the development of a subshrub layer in various humidity conditions over the growing season during the functioning of pasture ecosystems in reclaimed Molodezhny-teresken territory. The main taxation indicators used to assess the development of Krascheninnikovia ceratoides were determined: height, crown diameter, plant standing density. The research was based on field taxational and morphological measurements of the subshrub and calculations of the complex indicator D. The study revealed that the generalized analysis of the biometric parameters of Pamirian winterfat according to criterion D was an objective tool for assessing its development in the prevailing climatic factors of a certain year. A direct correlation was established between the amount of precipitation in autumn period of research years and the values of the integral indicator D (r = 0.97) with its higher value in 2012 (D = 0.905). There is a high level of direct correlation between the values of the integral indicator D and the yield of feed mass (r = 0.90). Krascheninnikovia ceratoides reclamation and forage plantations have stability, durability, high price-forming potential and are the best way to improve and restore pastures in arid and semi-arid zones.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47332944","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}

Before planting Carob seeds must be treated in order to disturb mechanical dormancy. The main reasons for the decline in genus Ceratonia L. are anthropogenic impact on natural ecosystems, as well as the uses of Ceratonia for many goals. This problem is aggravated by the fact that seedlings of Ceratonia in nature are very rare because of organic dormancy, and the distribution of carob occurs mainly with the help of seeds. The aim of this work was to study the methods of pre-sowing treatment of dormant Carob seeds. This study was conducted on a wild Carob genotype grown in Syria. Four different pre-sowing treatments were the following: soaking in boiling distilled water (70 С) for 10 min; soaking in boiling distilled water (70 С) for 10 min + soaking in distilled water for 24 h; acid scarification with sulphuric acid (H2SO4); acid scarification with sulphuric acid (H2SO4) + soaking in distilled water for 24 h.
