This research was carried out in the Research Center of the Faculty of Agriculture in Al-Muslimiya, 240 hybrid Babcock B300 female laying hens were randomly distributed since the first day of the experiment into four independent groups. Each group included 60 birds according to three replicates (20 birds in each replicate). Lactic acid bacillus was added to the feed mixture according to three levels (50 mg/kg; B group, 100 mg /kg; C group and 150 mg/kg; D group), while the first group was considered as a control group (A group) and was without additions. During the production period, the results showed that the addition of lactic acid bacillus led to significant differences (p<0.03) in the egg production and shell thickness compared with the control group. The additions did not affect the egg weight and feed consumption rate as well as the feed conversion ratio. The birds of the third group (C group) showed clear superiority in various productive traits compared to others in the other groups throughout the productive period followed by the birds of group D and then group B. The current study concluded that adding 100 mg /kg lactic acid bacillus to the feed mixtures for laying hens will contribute to raising the productive efficiency of laying hens and improving egg specifications.

The research was conducted at the Research Center of Agriculture Faculty of the University of Aleppo. 240 chickens of Babcock B300 strain were used and distributed randomly from day one into four independent groups. Each group included 60 birds distributed into three replicates (20 birds). The control group (A group) was fed a balanced standard feed mixture (1-18 weeks) without additives, while lactic acid bacillus was added to treatments groups according to three levels (50 mg/kg feed; B group, 100 mg/kg feed; C group and 150 mg/kg feed; D group). Haematological analyzes were performed over two- time intervals (1-21 weeks and 22-32 weeks). In the first time interval, results showed that a rise in blood albumin (P<0.001) was also observed in C and D groups compared to the A group. The rates of blood globulin increased (P<0.02) in the D group compared with the rest of the groups. No significant differences were noticed across the various groups for the total number of white blood cells and lymphocytes rates. In the second time interval (productive stage), significant differences (P<0.01) were noticed across the various groups in the percentages of the total protein (the highest value was 4.75 g/dl; B group) and serum albumin (the highest value was 3.26 g/dl; D group). It is concluded from the current study that the addition of probiotics to the mixtures of laying hens had a significant improvement in the immune parameters in the blood.

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 ).
