Abstract
The purpose. Perfecting pedigree and productive qualities of Obroshin grey and white gooses at growing «in it». That has allowed saving valuable qualities of initial livestock. Methods. Selection-pedigree work was carried out with the use of instrumental methods and the newest recommendations concerning application of physiological- and-biochemical markers of assessment of economically beneficial attributes, supervisory control of exterior indexes and methods of analysis of variance. Results. Experimentally is fixed that average egg production of gooses in I group made 41 pieces of eggs for a head, II — 40,5, III — 38,6, IV group — 38,1 pieces of eggs. Average mass of an egg in I group made 160,1 g, II — 162,4, III — 153,2, IV — 159,1 g. Breeding efficiency of eggs was above at gooses of I group — 84,3%. The maximum hatchability had gooses of II group — 76,5%. Preservation of young birds in I group was the best and made 92%. Conclusions. By results of slaughter it is determined that mixed Obroshin white gooses predominated above coevals by pre-slaughter alive mass, mass of viscerated carcass and edible parts of a body.

Key words: gooses, egg production, breeding efficiency, hatchability, preservation of young birds, dressing percentage.
