The study results are presented in the paper. The economic use period of the study cows did not have statistical differences and lasted 3,42–3,43 lactation periods. Black-and-white cows exceeded Kholmogory cows in the lifetime milk yield (by 3416,5 kg), fat content in milk (by 0,47 %) and milk amount in terms of basic standards (by 6317,7 kg) (P > 0,999). The optimal age for the first insemination of black-and-white cows can be considered 16–17 months, since insemination at the specified age ensures highest longevity in cows (3,85 lactations) and the highest lifetime milk yield indices (21347,8 kg), also expressed in terms of basic standards (27065,6 kg). Too early insemination of the black-and-white cows (up to 15 months) is not recommended, as it results in the decreased lifetime milk yields (up to 15491,4 kg), fat and protein content and shortens the economic use period of the animals up to 3,33 lactation periods. The lowest longevity (3,07 lactation periods) was observed in the black-and-white cows inseminated at the age of more than 20 months. The Kholmogory cows demonstrated an increase in lifetime milk yields (1084,5 kg (P > 0,95)) and the economic use period (1,05 lactation period (P > 0,999)) when the age of the first insemination was increased. However, as the fat mass ratio in milk decreased (by 0,06 % (P > 0,999)) and the protein mass ratio in milk fell (by 0,02 % (P > 0,999)), the increase in lifetime milk yield in terms of basic standards resulted from the increase in the age of the first insemination has no significant differences.","PeriodicalId":253385,"journal":{"name":"VESTNIK OF THE BASHKIR STATE AGRARIAN UNIVERSITY","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132140081","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}

Features of their seasonal growth and development rhythm, morphometric indicators were considered, success of the plant introduction was measured. The study was conducted in the South Ural botanical garden. Silaum silaus and Levisticum officinale both have spring aftergrowing at the end of April, budding in the second ten-day period of June; Levisticum officinale starts to blossom in the first ten-day period of July, while Silaum silaus starts to bloom in the second ten-day period of July. The blooming period of both plants averages 35 days. Seeds of Levisticum officinale begin to mature at the end of August, while seeds of Silaum silaus start ripening in the middle of September. In comparison to the second species Levisticum officinale features higher rates in height and stalk thickness, however, the plant forms three times fewer bottom leaves and generative shoots. Morphological indicators have standard variation rates (from 1,4 to 19,7 %). The introduction of Silaum silaus and Levisticum officinale revealed that in the Bashkir Cis-Urals the plants complete the development cycle, that is, blossom, give yield, set full seeds. The study plants can be recommended for use as raw materials in food production, cooking and alcoholic beverage production.","PeriodicalId":253385,"journal":{"name":"VESTNIK OF THE BASHKIR STATE AGRARIAN UNIVERSITY","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121957461","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}

Based on the literature review and analysis of the mixing process conducted in the Samara State Agricultural Academy, the design of the blade mixer was developed. The mixer consists of a body where there is a horizontal shaft with working bodies, made in the form of radial blades of helical shape. There are received equations that allow determining the concrete uniformity depending on a number of the impacts of the mixer blades per unit of the concrete weight as well as on the concrete weight that act on the blades of the slow-speed mixer. The power function is adequately described by the experimental results of 98 % confidence probability. In the studied areas of changes in independent factors rational values of the number of impacts per unit of the concrete weight is not less than 800 PCs/kg, as well as the concrete weight having impact on the blade of the slow-speed mixer is not more than 0,001 kg/PC.","PeriodicalId":253385,"journal":{"name":"VESTNIK OF THE BASHKIR STATE AGRARIAN UNIVERSITY","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122312545","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}
