Abstract EN

The experiment was conducted at the poultry farm , Department of Animal production , College of Agriculture / University of Tikrit the period between 8 / 4 / 2014 and 12 / 5 / 2014 .

The study was aimed at investigating the effect of using various levels of Dried Distillers Grains and supplementing with the Iraqi probiotic together with performing a fermentation treatment of a ratio one water/one diet for 24 hours at 35° c .

1125 broiler chicks ( Ross 308) at one day age were randomly assigned to 15 treatments .

Each treatments includes three replicates and each replicates consists of 25 chicks ( 75 chicks for each treatment ) .

The treatments used were as follows: Treatment 1 : The control , no supplement ( the negative control ) .Treatment 2 : The control + Iraqi probiotic ( the first positive control ) .Treatment 3 : The control + Iraqi probiotic + Fermentation ( the second positive control ) .

Treatment 4 : DDG 5 % .

Treatment 5 : DDG 5 % + Iraqi probiotic .

Treatment 6 : DDG 5 % + Iraqi probiotic + Fermentation .

Treatment 7 : DDG 10 % .

Treatment 8 : DDG 10 % + Iraqi probiotic .Treatment 9 : DDG 10 % + Iraqi prbiotic + Fermentation .

Treatment 10 : DDG 15 % .

Treatment 11 : DDG 15 % + Iraqi probiotic .

Treatment 12 : DDG 15 % + Iraqi probiotic + Fermentation .

Treatment 13 : DDG 20 % .

Treatment 14 : DDG 20 % + Iraqi probiotic .

Treatment 15 : DDG 20 % + Iraqi probiotic + Fermentation .

The chicks were feed on diets having similar amounts of energy and crude protein percentages according to ( Ross 308 rearing Guide ) .

The diet were supplemented in a ground form where as the water was available freely at all times .

the lighting and management schedules were arranged according the standard procedures presented in the guide .The broiler rearing period was 35 days .

The results obtained a significant superiority of T2 over all other treatments excluding T1 , T5 and T7 with respect to PI and EI Higher Dressing percentage was recorded in T10 broiler carcasses as compared with all other treatments .

The differences between treatments for the relative weights of abdominal fat , heart , liver , and spleen were found to be non consistent .

Fermentation process have showed a significant increase ( p < 0.05 ).
