Nezhlukchenko T. The theoretical background and the practice of the perfection of the selection proceess of sheep's in the ascanic merino breeding

Sheep. The purpose - theoretical substantiation and perfection of methods of hereditary improvement new tavrishes type such as ascanic merino sheep. Purebreeding cultivation, crossing with improving breed - Australian merinos, genetic-mathematical and statistical methods (clasters, travelling, correlation and regression the analyses). For the first time on the basis of results complex genetic-populational of researches is theoretically proved and is developed more perfect system breeding and increase of genetic potential of efficiency merino sheep. The offered methods are introduced in breeding economy, that promoted increase of efficiency of ascanic merino sheep of breed on wool weight of a pure wool on 18,7%, on an exit of a pure fibre on 19,5%. The general economic benefit has made 345,6 thousand grn.
