Background Duration of fertility (DF) is an important economic trait in poultry production
because it has a strong effect on chick output. Various criteria or traits to assess DF on …

Simple Summary In alternative poultry production systems, a key aspect for the viability of
the hatching egg is its storage before incubation, its management being less standardized …

ABSTRACT The effect of 0-, 7-, 14-, 21-, 28-, and 35-d storage periods on hatchability and
weight loss during storage and incubation of red-legged partridge (Alectoris rufa) eggs …

This study was carried out to investigate the effects of different breeding systems (breeding
on the ground and in the cage) on the egg production and egg characteristics of Rock …

ABSTRACT A study was conducted to determine the effect of live weight of partridges on
egg production and egg quality characteristics. A total of 144 Rock Partridges were divided …

In this research, partridge eggs were stored during zero to 7, 8 to 14, 15 to 21, 22 to 28, 29 to
35 and 36 to 42 d, respectively. The effect of different egg storage periods on egg protein …

The aim of the present study was to investigate, in red-legged partridge (Alectoris rufa) eggs,
the effects of 7-and 42-d storage periods with different storage temperatures (15, 12, and 9° …

This study was conducted to determine the effect of egg weight on chick weight, egg weight
loss and hatchability in partridges. Eggs (847) obtained from rock partridges (44-46 weeks …

1. Changes in water loss, eggshell conductance and hatchability with flock age were
monitored in layer hens in a commercial hatchery. 2. Optimal water loss for maximal …
