Selva Andina Anim. Sci. 2022; 9(1):23-36. In The objective of the research was to describe quantitative genetics and breeding principles in animals destined for livestock production. Economically important characteristics, such as body weight gain, egg, milk, and meat production rate are quantitative or metric typologies, traits with continuous variability. The action of addictive genes tends to originate a normal phenotypic distribution between the means of two progenitor populations, while multiplicative genes create geometric series governed by genes with multiplicative action. In addition, it should be considered that the most important factor in the creation of effective breeding techniques to optimize the genetic quality of animals is heritability, as they contain all types of gene action. In addition, parametric and non-parametric methods offer us a solution that becomes helpful or appealing to the questions that arise from the research and testing of hypotheses that are presented, we should also mention the models that explain the action of genes, such as breeding value and selection and production ability. Animal producers apply selection following several criteria in parallel as mating methods (panmixia, inbreeding, and heterosis). Finally, the application of breeding processes leads to a sensible selection by mating with special intentions without restrictions. 2021. Journal of the Selva Andina Animal Science. Bolivia.

Currently, beekeeping encompasses several health problems, which have drastically affected the populations of beehives in production. Among the diseases affecting bees are: American foulbrood, European foulbrood, limebrood, stonebrood, nosemiasis, acariosis and varroasis, among others. The Varroa destructor mite, which acts as a vector of different diseases and is recently associated with colony collapse syndrome. This mite affects bees during the phoretic and reproductive phase. However, the indiscriminate use of synthetic acaricides, in addition to having a harmful impact on the environment, affects the safety of products derived from the hive. In addition, they have originated resistance in V. destructor populations. This has forced the development of new strategies and treatment alternatives, such as the use of various plants native or endemic to the region (milling, extracts, oils and/or dehydrated powdered extracts). Plant essential oils are volatile aromatic compounds, mainly terpenoids, phenylpropanoids, monoterpenes, sesquiterpenes and alcohols, which have a wide range of antimicrobial and antioxidant activity, so the addition of essential oils of clove, eucalyptus, mint, rosemary, oregano and cinnamon can be beneficial in the apiary. The uses of these products can minimize production costs, encouraging producers to use these products.","PeriodicalId":31533,"journal":{"name":"Journal of the Selva Andina Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72517541","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}
