Ostapenko V. Theoretical substantiation and working out of methods of valuation pedigree and productive qualities of present-day poultry gene pool

The object of researches is Conformity to the law of forming of egg and meat productivity of bird under act of inherited and paratipic factors, development of the system of estimation of pedigree and productive qualities of bird of basic and reserve gene pool. The purpose of researches is the theoretical ground and practical improvement of methods of estimation of pedigree and productive qualities of bird of egg and meat direction on the basis of the use of additional selection signs. Methods of researches - zootechnics, comparative, statistical, dispersion, population. Results of researches - For a theory: First on the basis of complex selection-genetic researches the developed innovative methodical approaches to the rise of productivity of bird of the best world and home gene pool. The offered system of informative analysis of phenotype and genotype features of present gene pool of bird with its basic structural elements. For practice: The use of the offered principles of systems analysis of genofond population of agricultural bird allows to carry out the detailed analysis of genetic resources of agricultural bird in Ukraine and is foundation for the choice of the most perspective lines, cross-country races for the subsequent use in the pedigree or commodity (industrial, private, farmer) economies.
