This study was conducted at the Faculty of Agriculture, Damascus
University, during the period from the beginning of January and the beginning
of April, during the year 2002, on 107 local rabbit offsprings at one day age,
were divided according to
the color into five groups: 27 white, 22 black, 25
brown, 14 red, and 19 gray, then given numbers at the birth on her abdomens
and were weighted weekly, after that they were weaned at age 28 days.
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
there low content of metabolic energy and raw protein with
comparison between them and the mixtures of control group.
