VARIABILITY, HERITABILITY AND CORRELATIONS OF EGG SHAPE IN THE ZATORSKA GOOSE
2010, 11 (4) p. 433-436
The experiment was aimed at the evaluation of inheritance of goose egg measurements, egg shape indices and egg weight as well as the relationship between these traits. The research was carried out in the flock of the Zatorska geese, belonging to the FAO registered genetic resources of poultry. Seven hundred sixty-one eggs from pedigree bred geese in their first to fourth reproduction seasons were included in the analysis. Average egg shape index was 68.8%, average shell surface area was 140.6 cm2. Egg weight of geese in different age was 165 g. Heritabilities and genetic and phenotypic correlations estimated between the analysed traits of goose egg are presented.
