دراسة بعض صفات بيض التفريخ عند الدجاج البلدي السوري في البيئة الساحلية تحت ظروف التربية الريفية السرحية

This research included 1281 eggs collected from some villages in Lattakia. The aim was to study the most important traits of incubation eggs. 865 out of total eggs were selected for incubation (67.53% were suitable for incubation). Thus, the average egg weight of the studied eggs was 50.2 gr; for incubation eggs, it was 52.3 gr. The average of the index form was 75.8%. and the percentage of the fertility was 89.8%, hatchability 75%, and chicken hatchability 65.54%. This study indicates the low level of the values of these descriptions compared with the given values which are demanded by and limited to the international breeds and crosses, and how much are they influenced by genetic and environmental factors in order to set the right future programs needed to raising and improving these values; at present, they don’t reflect the potential ability of the genetic combinations for this local kind.
