THE INNOVATIVE SYSTEM of IN-DEPTH SYNTHETIC SELECTION of INTENSIVE TYPES of the SHEEP of BREEDING FARM "Askania Nova" for the FORMATION in UKRAINE the MARKET of BREEDING PRODUCTION
The results of researches on the use of innovative system of in-depth selection of intensive sheep types - Askanian crossbred and Askanian black-heads breeds, in small closed populations, to generate export potential of world-class breeding resources, are given in the article. The effect of feeding level on indicators of reproductive ability of ewes and viability of lambs was defined. It was found, that the recovery of genetic resources is due to their resistance to stress, which was formed during five generations under the influence of the permanent stressor, that is the unfavorable feeding conditions, while maintaining a positive relationship of the main breeding traits. If sheep have had providing of the fodder at the level below 80% of the norm, the breeding performance indicators are absent. It is discovered, the unique acclimatization and adaptive capacity of the intensive types lambs, their viability is 98%. The innovative system of synthetic in-depth selection provides the creation of a prominent animals of intensive types by selection of special pairs.
