dc.description.abstractThis research was conducted at the University of Ankara, Faculty of Veterinary Medicine Farm. The three hundred and sixty of one-day old chicks were seperated to male and female sex groups, and each sex group were also divided in to control, experiment I and 2 groups. Regimen feeding programme applied as crude protein 23.10 % from 1 to 11 days for all groups; 21.80, 20.20 and 18.40 % from 11 to 31 days for control, experiment I and 2 respectively. All groups were fed with % 18.40 crude protein from 32 to 47 days of age. Metabolic energy levels were 3117.80, 3083.69 and 3120.55 kcal / kg for all diet periods respectively. Animals were slaughtered at 40 and 47 days of age. Body weights at 47(th) day for males in experiment 1 and control groups were found similars (3075 ve 3086 g). The best feed conversion rate was found in males of experiment 1 groups (1.643 ve 1.763). Dressing, chilled dressing, breast, thigh and wing weights in males were found heavier (p<0.05, p<0.01) than females and similar in males of experiment I and control. The abdominal fat weight were high (p<0.001) in female and control groups. The average values estimated for the meat pH was similar in male and female as well as in experiments and control groups. Lightness, redness and yellowness (L*, a*, b*) values were high in females, water holding capacities were similar, cooking losses value was high in both male and experiments (p<0.01). While the crude protein values in experiment groups were high among groups, the intramuscular fat content was statistically similar. The percentage of crude ash and dry matter were Sigh (p<0.001) in control, the saturated fatty acid was similar, mono and polyunsaturated and omega-6 fatty acid were also similar or high in experiment groups. Antibody response to sheep red blood cell was found to be high (p<0.05) in control groups. In conclusion the body weight and feed conversion ratios were found high in male groups. The growth performance and carcass yield of male groups in experiment I were similar to control. There were no significant differences for meat quality and viability. Omega-6 in experiments over groups and antibody response in control were high. Hence sex separate rearing and diet programme in experiment I could be suggested in practical application.en_US
