الملخص EN

This study was conducted at poultry farm pertaining of the Department of Animal resources, College of Agriculture at University of Kufa during the period from 8/13/2014 to 9/17/2014.

The objective of this study was to investigate the effect of partial or complete replacing of fermented wheat by Saccharomyces cerevisiae, Iraqi probiotic and rumen liquor instead of corn on some productive performance, production index and economic figure.

A total of 360 one day unsexed Ross-308 chicks were used in this study.

The chicks were randomly distributed into eight equal treatments, forty five chicks for each treatment with three replicated per treatment (15 chicks/replicate).

The treatments were: T1= As control (basal diet with antibiotic); T2= As control (basal diet without antibiotic); T3= A diet contained partial wheat fermented by Saccharomyces cerevisiae; T4= A diet contained complete wheat fermented by Saccharomyces cerevisiae; T5= A diet contained partial wheat fermented by Iraqi probiotic; T6= A diet contained complete wheat fermented by Iraqi probiotic; T7= A diet contained partial wheat fermented by rumen liquor; T8= A diet contained complete wheat fermented by rumen liquor.

Results showed a significant or numeric increase in body weight through 5th week of age in T3 to T8 compared with T1 and T2.

Results also showed non significant increase in weight gain of accumulative weeks (1-3) for all treatments compared with controls.

The highest significant increase in cumulative weight gain (1-5) weeks were shown in T4 to T8 compared with controls and T3.

A significant increased in accumulative feed intake (1-5) weeks compared with controls.

Results also indicated non significant differences in feed accumulative for two periods (1-3) and (1-5) weeks compared with controls.

In addition, results indicated a significant increases in figure economic and production index in T4, T5, T6, T7 and T8 compared with others treatments(T1, T2 and T3).
