Krasnoschok V. Improvement of selection methods of the geese to increase reproductive qualities and feather and fluff productivity.

The work is devoted to study of regularities of growth and evolution of two-breed hybrids of the geese Reynsky x Kubansky of various classes of distribution according to mass in the beginning of ontogenesis and during reaching puberty. The influence of mass and index of the egg form in their incubation qualities, correlation of sexes, survival of young geese is noted. The close correlation dependence between live mass and outcome of plumage from female-geese is established. The influence of morphometry parameters on meat, feather and fluff, egg reproductive property is analyzed, that allows to organize groups of individuals of various direction of use. The data are supported by researches of biochemical peculiarities. They are mathematically processed. The introduction of received results gives appreciable economic effect. The offered methods of selection are applied both in production of products of geese farming, and in selective and breeder work. Key words: genotype, ontogenesis, productive qualities, classes of distribution, correlation relations.
