Possibilities of productive and reproductive performance improvement in geese: part I - genetic factors

SUMMARY Goose is a poultry species modest in terms of breeding conditions that enters breeding relatively late. These birds are characterised by the lowest production of eggs during the season, lower fertility and lower degree of hatchability than any other species of poultry. The productive and reproductive abilities of geese are dependent on genetic and numerous non-genetic factors. The right choice of the genotype, adequate application of breeding technology and incubation of eggs, as well as thoroughly planned selection, can greatly improve the reproductive properties of geese. Selection of genotypes and selection work for their improvement should be in accordance with regional breeding conditions, which allow maximum expression of genetic potential and conservation of animal genetic resources.
