This experiments is conducted to investigate the effect of using various levels of Dried Distillers Corn Grains and supplemented with the Iraqi probiotic with fermentation treatment on the physiological performance of laying hens . A total of 600 laying hens ( ISA Brown ) at the age of 22 weeks are used . Hens are assigned randomly on 12 treatment groups with two replicates for each treatment , 25 hens for each replicate .The treatment groups are as follows :
T1 : The control treatment , no supplementation ( the negative control ) T2 : The control treatment with Iraqi probiotic ( the first positive control ) . T3 : The control treatment with Iraqi probiotic + Fermentation ( the second positive control ) . T4 : Dried Distillers Corn Grains "DDG 10 % . T5 : DDG 10 % + Iraqi Probiotic . T6 : DDG 10 % + Iraqi Probiotic + Fermentation . T7 : DDG 20 % . T8 : DDG 20 % + Iraqi Probiotic . T9 : DDG 20 % + Iraqi probiotic + Fermentation . T10 : DDG 30 % . T11 : DDG 30 % + Iraqi probiotic . T12 : DDG 30 % + Iraqi probiotic + Fermentation .
The diets are given in a ground form . The lighting program and the water supplementing regime are performed according to ( guides for laying hen - ISA-Brown ) from the age of 22 weeks till the age of 37 weeks . The results obtained could be summarized as follows :
Diet supplementation with Iraqi probiotic significantly ( p < 0.05) increases the total bacteria count and lactic acid bacteria and decrease the count of E. coli in the jujinum of treated birds as compared with control – Treatments significantly increase the villi high and crypts depth in favor of the treatments which contained DDG The serum cholesterol in treatments which fed on diets supplemented with DDG exception the control which fed10% DDG fermented with probiotic .
DDG Treatments significantly( p < 0.05) decrease triglyceride compared with the T12 (30% DDG and fermentation with probiotic ) in addition to high significant in total protein and globuin experience for all treatments as compared with T11 (30% and probiotic ).
