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%) .
أجريت هذه الدراسة على 800 بيضة أخذت من قطيع أمهات دجاج اللحم من الهجين التجاري (روس) بعمر 7-8 أشهر وقسم البيض حسب الورزن إلى مجموعتين (45-55) غ و (56-65)غ
The research was carried out on two classes of hatching eggs obtained
from broiler breeder flock ( shifer starbro- Hybird ) 39 and 59 wk of age .
In each class the hatching eggs were graded into three groups according
to their weights.
The hatchi
ng eggs of each group were divided into three replicates .
Eggs of all replicates were incubated in the same incubator . At hatching
(115) chicks were taken from each replicate and fed in separate pen until 7
weeks of age . All conditions of housing, rearing and feeding
( vegetable diets ) were same for all birds of all replications.
