all hens distributed randomly on four separated houses(four treatments), each treatment include 3500 female plus 500 male.
This study aims to know influence of four levels ambient temperatures in summer season as fellow:(T1=28C).(T2=30C).(T3=32C).(T4=34C) on performance of breeder laying hens strain Tetra SL which imported from Syrian country.
All birds intakes the same production rations along periods of study.
Using Completely Randomized Design with one way experiment ( uni factor that is temperatures) and applicated SAS program in stasticals analysis of data.
The results shows high significant decrease in summer season on general performance .The power of these effects relative according to rising of housing temperatures along the period of this study among May – Sep months .
There were negative effects on egg production, egg mass, feed consumption, feed conversion ratio and less significant comprise with guide of producer company for these breeders.
Also decrease significantly hatchability percent, at every periods ( four weeks) at all periods in all treatments.
But there were no significant differences in egg shape index, egg broken, egg with double yolk between all treatments.
Our conclusion that this strain of breeders laying hens have been negatively affected by hot climate in south of Iraq.
