Резюме: в статье освещены генетические ресурсы якутской, приленской и мегежекской пород табунных лошадей Якутии. Показано, что новые породы, приленская и мегежекская, ввиду отсутствия внутрипородных типов, структурно не сформированы. В этой работе должны быть задействованы, помимо конных заводов, и племенные репродукторы. Якутская порода лошадей структурно состоит из трёх внутрипородных типов: коренного, янского и колымского. Установлена необходимость изучения коренного типа по изысканию выдающихся особей типа по продуктивным качествам и адаптивности к условиям содержания с целью выведения заводского типа якутской породы выраженного мясного типа.Ключевые слова: генетические ресурсы, табунные лошади, якутская порода, коренной тип, янский тип, колымский тип, приленская порода, мегежекская порода, внутрипородные типы, заводской тип якутской породы Summary: The article highlights the genetic resources of Yakutian, Prilensky and Mericskay breeds herd horses of Yakutia. It is shown that the new breed Prilenskaya and Magicscan, due to the lack of intrabreed types that are not structurally formed. In this work, should be involved, in addition to horse plants and pedigree reproducers. The Yakut breed of horses consists of three inbreeding types: indigenous, Yana and Kolyma. The necessity of studying the native type to find outstanding individuals of the type of quality productive and adaptability to the conditions of detention with the aim of removing the factory type of Yakut breed of pronounced beef type.
Displayed are the results of epizootiological differentiation of the Pre-Caspian sandy plague focus in the territory supervised by Astrakhan and Elista plague control stations (Volga-Kumsk Interfleuve). This differentiation is significant for further development of epizootiological monitoring practice in the enzootic regions. Using circular extrapolation method, designed is the map of the persistent epizootic region within the last period of the focus activation since 1979 till 2010. Depicted is the dislocation of focus activity nucleuses and areas where short-term epizootic process is registered. Identified are their qualitative characteristics. Determined is the fact that density of plague-positive samples in the nucleuses is much higher, than in the areas with non-recurring manifestations. This cartographic differentiation model can be used for justified and substantiated planning of epidemiological control measures and further investigation of problems related to plague epizootiology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
