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 1774 chicks of sexual separate chicken from
the hybrid Hibrd. The chicks were distributed into five groups, every group
contained three repelications, and the chicks were fattened until the age of six
weeks. The pro
gram of feeding and sex was as the following in every group:
The first group /control/: Its birds were both male and female /not sexual
separate fattening/, they were fed on three vegetal mixtures
according to age stages.
The second group: Its birds were only male, and it was fed on three vegetal
mixtures according to age stages /the mixtures of control group /.
The third group: Its birds were only female, and it was fed on three vegetal
mixtures according to age stages /the mixtures of control group/.
The fourth group: Its birds were only male, it was fed according to age stages
on three vegetal mixtures, which were distinguished by there high
content of metabolic energy and raw protein, with comparison
between them and the mixtures of control group.
The fifth group: Its birds were only female, it was fed on three vegetal
mixtures, according to age stages, which were distinguished by
