The work involved 15 varieties of hulled barley, which were grown for three years in conditions of the Krasnoyarsk foreststeppe (Minino farm, Emelyanovsky district, the Krasnoyarsk Territory). Climatic conditions in the research years differed significantly in terms of temperature and precipitation during the growing season. After harvesting plants, fat content in barley grain was measured by the chemical method according to GOST 13496.15-97. For barley varieties, two parameters of ecological plasticity (coefficient of variation; stress resistance index) and four stability parameters (indicator of level and stability of variety; homeostatic parameter; stability factor; index of selection value of variety) were calculated according to the indicated biochemical trait. It was found that Simon and Pallidum 4727 had the lowest value of plasticity and the highest value of stability (and, accordingly, the minimum sum of ranks) in terms of fat content in grain for the conditions of the Krasnoyarsk forest-steppe. G 18619, G 19589 and Dygyn were least valuable in terms of adaptability parameters with the maximum sum of ranks. It was shown that barley varieties with a higher fat content in grain were characterized by increased values of all stability parameters for this trait, and the indicated positive relationship was statistically proven for the Cs parameter. The result obtained shows that through the successful selection of barley for the maximum stability of grain fat content trait, oil content will not decrease.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68268314","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}

Lambs were divided into two groups - control and experimental, which were administered nanoselenium orally at a dosage of 0.5 mg/ kg of feed once a day, daily. Each group consisted of five male lambs. According to the findings, cholesterol levels dropped significantly at days 45 (P 0.01) and 60 (P 0.05), whereas triglyceride levels significantly rose at days 15 and 30 (P 0.01). Throughout the trial, the levels of uric acid and creatinine were constant. At days 15 and 60, aspartate aminotransferase (AST) levels were significantly decreased (P 0.05), while at days 45 and 60, alkaline phosphatase (ALP) levels declined (P 0.01 and P 0.05, respectively). At days 15 and 30, albumin levels dropped significantly (0.05), but day 60 saw an increase in globulin levels significantly (P 0.05). The drop in AST and ALP levels might be a sign that liver function has possibly improved. However, the drop in albumin levels and rise in globulin levels raise the possibility that taking nano-selenium supplements may affect how proteins are metabolized. The findings of this study concluded that the effects of nano-selenium supplementation on lipid metabolism, liver enzymes, renal function, and protein levels in male lambs were time-dependent. In addition to possible improvements in liver function based on decreased AST and ALP levels and changes in albumin and globulin levels, the study also noticed an initial transient increase in triglyceride levels that was followed by a decline in cholesterol levels. To determine the time-dependent changes in liver function, liver enzymes, as well as renal function in response to nano-selenium supplementation in male lambs was objective of this study.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68268381","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}

Prenatal influence of estrogens results in reproductive system disorders in an adult organism which is accompanied by parallel growth of steroid dependent cancers of the offspring: testicles and ovaries. The aim of the study was to perform immunohistochemical analysis of Bcl-2 marker during prenatal exposure to different doses of the synthetic estrogen analogue Sinestrol in the testes of the offspring of white non-pedigreed laboratory mice. After fertilization, the pregnant females were divided into 3 groups, one intact and two experimental groups. The intact group was unaffected (n = 10). The first experimental group, C-25 (n = 13), was injected with the estrogen drug Sinestrol in the form of a 2 % oil solution at a dose of 25 g/kg. The second experimental group (n = 13) was given the estrogen preparation Sinestrol in the form of 2 % oil solution in a dose of 40 mkg/kg. When the offspring reached sexual maturity, they were removed from the experiment. Immunohistochemical analysis was carried out on sections from paraffin blocks of testes of progeny intended for standard morphological study, the marker of apoptosis inhibitor Bcl-2 was determined on indices of cellular elements of male glands of progeny: spermatogonia, spermatocytes, sperm-tides, spermatozoa and Leydig cells. Expression of Bcl-2 marker upon exposure to the synthetic drug Sinestrol at doses of 25 and 40 g/kg showed that the number of positively stained cells in spermatogonia increased by 8.6 and 9.4 % respectively compared to the intact group. When the intact group was compared with experimental groups C-25 and C-40, the expression of Bcl-2 marker in spermatocyte cells and spermatozoa showed no difference, a slight increase in positively stained cells in spermatids was observed. Bcl-2 marker expression rate in experimental groups C 25 and C-40 decreased in Leydig cells by 56.0 (P 0.05) and 60.0 % (P 0.05), respectively. Administration of the synthetic estrogen analogue Sinestrol during fetal gland initiation resulted in impaired morphology in the testes in adulthood. The expression index of Bcl-2 marker in experimental groups C-25 and C-40 decreased in Leydig cells, resulting in apoptotic cell death, which is responsible for production of male sex hormone testosterone. The results can be used to select optimal doses of the synthetic estrogen analogue Sinestrol in the prenatal period.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68268925","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}

Ventral stabilization was carried out by forming an arthrodesis between atlas and epistropheus by inserting screws or spokes through articular structures and vertebral bodies from ventral surface and then fixing them with bone cement. In the studied method, there are also complications in form of failure of metal structures or damage to recurrent laryngeal nerve, but, according to statistics, the incidence of these complications in world practice does not exceed 20 %. Among the possible complications during the operation are death of animal because of sudden respiratory arrest associated with spinal cord injury, migration or breakage of implants, inadequate alignment of spine. In addition, implants may not be placed correctly causing chronic pain or damage to the spinal cord. As a result of the operation, 104 dogs fully recovered, partial preservation of neurological deficit was observed in 13 animals, 18 animals died in the early postoperative period. Complications that did not lead to a deterioration in neurological status and quality of life occurred in 17 animals. Analyzing the work done, the method of ventral stabilization in the treatment of atlanto-axial instability can be recommended as the most reliable and optimal method, since it is technically simple and has good long-term results. Statistical data showed good results, the method is effective and allows to fully return the animal to a quality life in more than 86 % of cases.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68268393","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 study showed that when Farnesol is added to the treatment regimen for fungal otitis etiology in dogs, small changes in the clinical composition of the blood are recorded, characterized by an increase in the number of erythrocytes and hemoglobin, a decrease in the number of leukocytes, with a decrease in the indicators of eosinophils and rod-shaped neutrophils in the experiment compared with the control. In addition, the complete absence of Malassezia pachydermatis in the smears of the ear contents after two weeks of therapy with a combined drug was proved. That is, in the experimental group, there were no cases of the presence of yeast-like fungi (YLF) in the smear after combined therapy with Surolan + Farnesol. And in the control group of 15 animals, YLF were observed in two with microscopy of ear exudate smears, but not in high concentration.

For this reason, the mycotoxicological study of various types of feed under production conditions is an indispensable component of veterinary support of industrial animal husbandry. As part of this study, a retrospective analysis of the results of a mycotoxicological study of feed for different animal species was carried out in the Omsk region in 2017-2021. All feeds received by the Omsk Regional Veterinary Laboratory for 5 years for the determination of mycotoxins were examined for the presence of ochratoxin A, zearalenone, T-2 toxin, aflatoxin B 1, deoxynivalenol. It was established that almost 70 % of the studied samples contained mycotoxins, including their maximum allowable level was exceeded in 74 samples. Exceeding the permissible levels was noted for the content of T-2 toxin (34 samples), zearalenone (27 samples), ochratoxin A (6 samples), aflatoxin B 1 (4 samples) and deoxynivalenol (3 samples). The largest number of cases of contamination was recorded in the study of feed and feed mixtures. The greatest danger is the multiple contamination of feed with mycotoxins.
