The feed restriction program is one of the main techniques in

growth curve manipulation for increasing production efficiency

in broiler chicken, therefore, this experiment was conducted to

determine the effects of different feed restriction levels, at

finisher phase from 30 to 42 days, on productive performance

and carcass traits. In this experiment a number of 90 Male Ross

broilers were used, the chicks were distributed into five

treatments at three replications for each treatment and six chicks

for each replication. The first group was control (T1) which the

chicks of this group were fed according to Ross Management

Manual, and (10, 15, 20 and 25% less than Ad-libitum) for T2,

T3, T4 and T5 respectively. The results showed that feed intake

at different levels was significantly (p<0.05) less than the control

group. Meanwhile, at 42 days old Live weight, body weight gain

and feed conversion ratio of (T2, T3, T4 and T5) were

numerically less than the control group, nevertheless, these

differences were not significant (p>0.05). The results also show

that carcass traits were significantly (p<0.05) affected by feed

restriction at which abdominal fat percentage in all treatment

groups were significantly (p>0.05) lower compared to control

group. Meanwhile carcass weight, gizzard percentage and

dressing percentage in all treatments were numerically lower

than the control groups, however differences were not significant

(p>0.05). In conclusion; results shows that using feed restriction

(less than the Ad-libitum feed intake decreased significantly the

feed intake without any effect on productive performance and

carcass traits.
