Study of crossing effection between black type of Syrian local hens and Egyptian Strain Fayoumi on some eggs indicators

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 Syrian 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%).

Effect of utilization of Artificial Insemination on fertilization rate in hatching eggs of Syrian local poultry

This research was conducted to apply the technique of Artificial Insemination in poultry for the first time in the Syrian Arab Republic , and study the differences between the impact of the use of fresh or stored semen on the fertilization rate in hatching eggs . Results showed that the response to massage was different between cocks, It was greater in the cock A and cock B while the cock C was the least response to massage. The greater volume of ejaculate was obtained from the cock A( 0.072) ml ,and the least volume of ejaculate was obtained from the cock B (0.05) ml . The volume of ejaculate obtained from the three cocks was ranged between (0.049 -0.072) ml. The value of X in the count ranged between (230 - 237) sperm, semen concentration ranged between (4.6 - 4.7) billion sperm / ml. It also found that Insemination with a fresh semen injection yielded fertilization rate (91%), While insemination with semen injection cooling at the heat +4 ̊ C for 48 hours yielded fertilization rate (67%) .
