الانتخاب لتحسين مؤشرات معامل التحويل الغذائي (FER)‎ بين جيلين عند النمط البني من الدجاج البلدي السوري

Abstract EN

The growth Indicators and (FER) have been studied concerning /144/ chicks belong to first generation (F1) and /144/of second generation (F2 ) from (1 – 49) days old.

The results of the research showed that the averages of the body weight relative to one day old were 36.8 g.

of (F1) chicks and 37.58g.of (F2) chicks.

Concerning the 49 days old, the living weight averages of these two generations were 539.96g.

and 556.14g.

respectively.

The average of the daily weight gain in (F1) ,was 10.26g./bird/day, compared to 10.58g in (F2) .The average of the daily fodder consumption was 35.06gr.

in (F1) and 34.57 g.in (F2).

FER in (F1) and (F2) was 3.3 and 3.16 respectively.

The research showed that the values of studied indicators relative to that type of the local poultry were very low in comparison with the meat production hybrids.

This assures the necessity of designing scientific researches in the poultry field to apply the programs of genetic improvement on the local animal species, and the target is to raise the values ofits productive indicators.
