Effect of egg sequence position on egg fertility and hatchability and early embryo mortality


, : Effect of egg sequence position on egg fertility and hatchability and early embryo mortality. Archiv fur Geflugelkunde 58(1): 18-23

14 341 eggs were collected daily from the 10th week of lay from 585 hens with an average laying cycle of 4.8 or 6.7 days. Of the eggs set, 13.2 and 1.5% of those from the 2 groups of hens respectively were first eggs laid after a pause of 1 day or >1 day, 11.6% were second eggs, 58.2% middle eggs, 12.4% last eggs and 3.1% single eggs.

Studies with turkeys (BACON and NESTOR, 1979), White Leghorn (BUHR, 1990), the broiler breeders (ROBINSON et al., 1991) have shown that first eggs in a clutch tend to have lower fertility and hatchability than subsequent eggs. This study was under...

Two hundred Large White turkey hens were fed diets varying in vitamin D3 supplementation (300, 900, or 2700 IU/kg feed) from day-old to 37 weeks of age. Hens receiving 300 IU vitamin D3/kg feed produced fewer eggs, which were lighter in weight and...
