Abstract EN

The aims of this study to evaluate the use of different systems of feeding with the addition IRAQI probiotic on the performance of broiler.

This study was conducted at poultry farm.

Animal Resources Department.

College of Agriculture University of Basrah.

One day of 270 unsexed chicks of Ross 308 strain were used in the study.

The chicks were randomly distributed into 6 treatments with three replicates.

Each replicate contain 15 chicks.

The treatment were as follows (1) control.

(2) early feed restriction 20% (8-21) days.

(3) late feed restriction 20% (21-34) days.

(4) control with addition IRAQI probiotic 0.3%.

(5) early feed restriction 20% (8-21) days with addition IRAQI probiotic 0.3%.

(6) late feed restriction 20% (21-34) days with addition IRAQI probiotic 0.3%.

The control treatment with added IRAQI probiotic achieved significant (p<0.05) increase on live body weight.

While the use of late feed restriction with.

or not adding probiotic led to significant (p<0.05) decrease in live body weight and body weight gain.

and use early feed restriction with.

or not adding probiotic led to significant (p <0.05) improvement in feed conversion.

And use early.late feed restriction with.

or not adding probiotic led to significant (p<0.05) decrease in mortality coparing with control treatment
