This research was carried out to study some hattching egg traits and chick weight at
day old in black type of Syrian local hens and Egyptian Fayoumi strain , and study the
differences in egg traits and chicks which come from hybrization between Syr
ian black
male and Fayoumi female.
Results showed that the average egg weight of Syrian hens was 52.33 g and of
Fayoumi hens was 46.86 g .
The fertility rate increased in hybrid egg compared with parents . It was87.94% in
hybrid compared with 84.08% in Syrian hens and 77.22% in Fayoumi strain hens.
The day old hybrid chick weight increased compared with Fayoumi chick. It was 32g
in hybrid chicks while it was 30 g in Fayoumi chicks , and it was lower compared with
black Syrian chicks (35g). Hatchability rate was 89.5% and 92.3% in Syrian local hens
and Egyptian Fayoumi hens respectively .And this rate decreased to 82.6% for the hybrid .
Chicks hatched decreased to 69.2% for hybrid compared with 72.93%for Syrian local hens
and 69.44% for Egyptian Fayoumi hens .
The mortality of hybrid chicks was 3.3% , it was lower compared with mortality of
Fayoumi chicks (6.05%) and higher compared with mortality of Syrian chicks (2.22%).
