Pedigree and productive qualities of Obroshin grey and white gooses at their growing

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.
