This study aims to determine the effects of storage period and egg weight on albumen pH and hatchability of hatching eggs. For this purpose, the eggs produced by native breeder hens (28 - 31 weeks of age) were used in a completely randomized design with a 3 × 8 factorial arrangement. The main factors were 3 egg weight ranges (46 - 49, 50 - 52 and 53 - 56) and 8 storage periods (1, 3, 6, 9, 12, ...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
