Effect of Using Different Levels Of Corn Distillers Dried Grains without soluble ( DDG ) , Iraqi Probiotic and Fermentation Treatment in the Some Productive Performance in Broiler

Abstract

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 ).
