Analysis of trends and factors in the development of dairy cattle breeding substantiates the directions for providing the country's population with milk according to the rational nutritional standards in light of international sanctions. The agrarian policy pursued by the state has increased milk production and reduced its imports but has not solved the problem of food security in the consumption of dairy products. The authors conclude that food security in the consumption of milk and dairy products will be supported by import substitution in the food market, the increase in milk production through technical and technological modernization of dairy farming, improvement of selection and breeding work and state support, concentration of milk production in specialized agricultural organizations and farms, the development of cooperation, improvement of livestock productivity through the use of modern technologies, improved use of the genetic potential of cows, strengthening of the feed base, and optimization of feed rations.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114750338","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}

Se caracterizó físico-químicamente los productos a emplear en la formulación de las bebidas. Se realizó un diseño factorial , donde quedaron establecidos los niveles de almidón y suero lácteo. Para esto se fijó en la formulación de cada una de las corridas experimentales la concentración de azúcar y se completó el resto con los componentes leche entera de vaca y de soya mezclados en una relación 7/3. La formulación mejor evaluada se elaboró a escala piloto y se caracterizó. Para el caso del 1,2 % de almidón independiente del contenido de suero en las formulaciones siempre se obtuvieron mejores resultados. Se apreció que la calidad sensorial del producto está condicionada tanto por la viscosidad como por el sabor lácteo. La formulación mejor evaluada por parte de los catadores fue la que contenía un 1,2 % de almidón y 30 % de lactosuero. La caracterización sensorial de la bebida arrojó una calidad excelente, debido a la percepción de una correcta combinación del sabor café, sabor a soya, y sabor lácteo. Presentó un contenido de sólidos totales de 17,8 % y una acidez de 0,07 %.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129937303","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}

It is essential to conduct a comprehensive analysis comprising as many studies as are available to summarize the separate studies and provide an overall view of how the research field has been evolving over the last few decades. This paper performs a bibliometric analysis using a large dataset of published papers from 2000 to 2021. The study examined 1022 publications from those 20 years. About 79% used statistical analyses, and machine learning techniques were utilized by almost 21%. It is worth mentioning that the publications related to statistical analysis were grouped in the following way: multivariate or univariate statistical analysis (52.4%), Bayesian analysis (21.7%), and spatial analysis (50.5%). There were several key points regarding the overall results of the research. Results illustrated that publications had grown significantly during the last two decades. The majority of the publications come from the United States. In addition, the most prolific authors and journals were identified. Over the last decade, due to advanced technological methods, more research has been focused on enhancing and designing Bayesian techniques for using psychoactive substances.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123235113","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}
